I got myself a Samsung 64GB Pro UHS-1 card directly from Korea. It's one of the newer 20nm cards rated at 20mB/s write and 70mB/s read speeds.
I got it from this seller on eBay for $91. I got it within a week from ordering it, which is quite good considering I'm on the other side of the world.
Compared to the SanDisk 64GB UHS-1 card, on the phone itself I'm getting:
With SD Card Tester app:
SanDisk: 9.25mB/s write, 12.95mB/s read
Samsung: 13.71mB/s write, 12.78mB/s read
Edit: I increased the readahead to 1024K and I'm getting 18mB/s read on the Samsung.
The SanDisk card shows up as 59.47GB, the Samsung one as 58.53GB on the phone.
Seems disappointing considering the advertised speeds. However this is caused by the host controller on the phone seemingly limited to 100mbit/s on both cards, so for people who want to expect a big boost here, don't. I guess we won't see better scores until Exynos 5 devices come out.
Tested on my laptop reader with an adapter:

It looks like the reader itself is the bottleneck here too, however the SanDisk card is clearly outmatched by almost a factor of two by the Samsung card, especially in the write tests.

Speeds may be twice as much but so is Samsungs price. I got my Sandisk for $46. I think I can wait for the Samsung price to come down.

Yes and is the Note 2 or any other available device really in need of that extra speed? I doubt it does. When the price comes down then it will be a good buy for phones.
no phone supports uhs 1, so you won't get the advertised speed.
try to get a uhs 1 reader and try again.

I don't know what the hardware differentiation is between normal and UHS speed modes, but the host device driver in the phone does support and uses UHS.

That's an up to advertisement, it doesn't guarantee anything. It also doesn't explain why the Samsung one is twice as fast as my SanDisk, because they would be both be limited at the same speed of the host controller if that's the main cause.
The host controller driver in the phone runs at SDHCI spec v2 while v3 is the new version, however the speed is determined by the host controller bus width and speeds and are independent of the spec beyond the minimum requirements. The SDHCI on this SoC is also the HSMMC which controls the internal memory and that one is capable of 62-65mB/s read speeds. If anything, the USB 2.0 bandwidth limit is more of a problem.

it's upto you to use compatible and supported hardware, it doesn't matter if you pc has the supported driver, do you have a uhs 1 card reader, if not , the speed is not reachable.
for the sandisk ultra it state upto 30, i have a 32 and 64, both reach 38mb/s.
you cannot test full speed on the phone, it a card reader to pc that you need, as i said, no phone supports uhs 1.
if you want faster card, and you do need a uhs 1 card reader, try the sandisk extreme pro at 95mb/s.

I'm talking about the phone's host controller and that's the spec it is running at extracted from the hardware, and on that the Samsung is still faster, it's an apples to apples comparison regardless if the top speeds are limited or not.
Those extreme pro's are nice, but come only in maximum of 16GB and are outlandishly unavailable or expensive, they're the same price as the 64GB ones.

If so then why buy the expensive SD cards to put on the phones that not yet have the needed support in order to have the max. speeds?
In fact you put the card into the fone most of the time, not to the reader into the PC - so the card's speed when plugged into the fone is the thing that is most important, not the speed when you test in ur PC.
=> Wait until the prices of the new SD drop & the new support for them come out for the fones

I have just got myself a Transcend microSDHC Ultimate 32GB to try out; have been using the SD Ultra 16GB (both Class-10)
The seller has both cards for the same money but he points out the TS as he told the speed was more stable when copying big files (like HD Movies).
Have checked the serial in: http://vn.transcend-info.com/Support/SerialCheck_tw.asp?Func1No=3&Func2No=207
Initial impression, not tested yet.
- Sandisk: the outer box and also the card itself to me was better, also the adapter was printed with characters, numbers and Made in Taiwan; the box of the Trans printed Made in TW; while in the microSD itself: Made in Korea; the adapter was not printed with anything.
The performance and stability is to be tested when I get back home The SD has served me well for like a year.

Of all the card trandscend, adata and sandisk tend to be the most reliable and stable cards available, whiles toshiba and kingston has the speed, but the speed do fluctuate alot.
sandisk cards are made by themselves, whiles transcend are usually rebadged from sandisk and other manufacture.
adata also has cards made from sandisk and themselves.
kingston is really really bad, stay away from it. SanDisk might be slower but it is solid and yes Transent is very very good, stable and fast.
Transcend Class 10 MicroSD (not the UHS I version)

thanks for the review! but just an fyi for anyone out there thats thinking of buying a samsung card. average at the time of this post is that the cards are for 90 online. I found on another thread that someone bought the card off frys.com for 70. its the us brand model too
Here's the SanDisk card as measured on my MacBook Air (mid-2012), the card reader is PCIe based so there shouldn't be any bottlenecks.
Instinctively I'm thinking I have a bad card because I reckon it should go faster than this. But meh, I'm pretty happy with those results.

ok I see a lot of quadrant scores and stuff here .. which is great and all .. but I would like to see what everyone is using as far as their sd card goes. This will help others who see this choose an sd card that is proven to be effective here .. a reliable source to say.
I would like:
1) Brand, Size of card, and Class rating
2) Price and where it was purchased at
3) what you think of the card
4) a screen shot of the speeds .. I used SD Tools (free and it lets you save a screenshot)
so here is mine:
1)OEM systems 32GB class 10
2) $57.25 on amazon http://www.amazon.com/OEM-microSD-m...4AJO/ref=sr_1_2?ie=UTF8&qid=1320822033&sr=8-2
3) I really havent decided if I like this card or not .. when I run the benchmarks in my class 10 8gb card from sandisk the speeds are much better (15mb write to 8mb write now). I dont know if I can tell a difference in the performance of the phone ... maybe a little loading pictures in my album... but I also have my Nikon DSLR 7000 full size photos on there as well .. so its to be expected i guess.

if the write speed is ABOVE the class number, then it means you got a good card
in your case it was rated Class 4, so it supposed to guarantee a minimum of 4 MB/s write to the SD card
and your score shows 5 MB/s that means it's good, and not a fake counterfeit or defective unit, which might have shown 2 MB/s
even on the oldest of my phones like the Treo650 it was able to easily write above Class 6 speeds

they offer life time warranty, however it takes a bit of work for them to replace your dead cards
Patriot 32Gb Class 10
Originally bought this card maybe one week after it was released, approx one year ago. Bought it on Amazon for approx $105. Recently totally crashed and could NOT be formatted. I did have off and on weird issues with SD card not recognized, and basically had to reformat. Was running the card in Nexus one, as well as the Sensation 4G. Patriot did an RMA on the card and the replacement runs twice as fast as the original. I think my first card had some weird bugs. Glad it died off. Patriot did honor their unconditional 5 year warranty BTW. I typically get 10MB/s write speed when copying ROMs over from my PC over USB. I used to get only 3Mb's at best with the original card. Using BeastMod II v2.1 ROM.
Edit:
http://forum.xda-developers.com/showthread.php?t=1010807 go to this thread and it describes how changing the cache settings can alter read speeds. I seem to get better results using 4096 setting, while I used to use 1024 setting on my Nexus one. Best to test settings for yourself. My read speeds increased to a consistent 21.0MB/s. Write speeds were anywhere from 9.0 to 10. The cache settings only affect the read speeds, BTW as far as I know.

yes, the cache only works for read, and it doesn't improve it by much on fast phone like ours, is good for older phones that were Sub 1 Ghz
as for your writing speed, it did not even reach the minimum guaranteed of 10 MB/s
you are only getting 9 MB/s write on both test
Yet another reason why i do not trust that brand Patriot

May I ask why you specifically want a Class 6 and not a Class 4 (generally quicker) or Class 10 (quicker for large transfers only (unless you get a very good one))?
Sent from my GT-N7000 using XDA App
edanfalls,
Class 4 has a lower transfer speed (than Class 6 and above) for both small and big files.
Class 6 is a "golden middle" between low (<6) and high (>6) Class cards - fast Class card for entry Class card price.
Nice choice!

Yes, for sequential low-queue-order reads. This is mostly irrelevant for real-world usage.
Class 10s are usually actually slower in real applications. Of course, if you want the extra speed for simply transferring files, then a Class 10 will be better for you (which is why I stated that Class 10s are quicker for transfers in my first post).
There are some Class 10s which perform better than Class 4s with random high-queue-order reads and writes, but these aren't typical Class 10s and cost a lot more.

Well no reputed manufacturer makes class10 at the moment. The ones tht makes are having shaky performance and data errors within a few months.
If one needs a fast card the safe route is to go with class6 cards... and i want it coz i intend to watch 1080P movies on my phone and it requires transfers as well....
PS: Maybe i will get a class4 card tommorow, which is easily available and i hope it wont lag for any of my use.

Verbatim, Kingston, Lexar... these are all reputable brands and are selling Class 10s.
Mostly they all use the same flash manufacturers anyway.
The only 64gb cards ive seen are these "Sandisk 64GB Mobile Ultra microSDXC Memory Card, up to 30MB/s read speed" I just bought one for $175 from here so not cheap but I wanted more storage for my note. They will get cheaper once more 64gb cards get released but sandisk is the best brand for SD cards.
http://www.scorptec.com.au/computer/42572-sdsdqy-064g-u46sa
I have seen them online for $165 but I only buy sdcards from people I trust and these guys have a shop near my house where I get most of my computer stuff.
Not sure where you live but this is from Australia so you may want to check if they ship OS. I would never trust private sellers for any SD cards as theres just way too many fakes around.
Here is a speed test I did on the card using win7x64 with USB 2 which could be why I don't get much over 20mb/s with any of my cards.

Going by this test it would be a class 6 but they dont have a class rating anywhere apart from 30mb/s read speed which I dont hit. Just transferring over my 32gb cards data to this and am getting a speed of just over 7MB/s so id rate it a c6
Thanks! I was interested in the 64GB card myself but couldn't find any reviews.
Is the Note totally compatible with SDXC?
Also, I remember reading somewhere when it was released a few months ago that it is officially a Class 6, so your rating is spot on
The random 4k write performance is excellent, that makes my mind up.
For those in Europe interested in the 64Gb microsd card, Amazon Germany has it for sell at 90 Eur.
I just brought one for £82 inc delivery, should get here this time next week.
Since a class 10 32Gb card cost £40, 64Gb class 6 card for £80 is not a bad price if you need the storage space.

I've got a Sandisk 64GB Mobile Ultra microSDXC Memory Card in my Note and it works as expected.
I've tested a Kingston 32GB microSDHC Class 10 Memory Card which also worked perfectly fine.
I suggest for mobile usage you get the mobile ultra. The random 4k write speed kills the standard class 10 cards which were optimised to do quick sequential writes only.
I got my Sandisk 64GB Mobile Ultra microSDXC from a store in Australia called Scorptec but they are available all over. look up amazon, etc.. (can't post links because of new member)
Class 10 on Amazon very fast and good
You guy's are the luckiest bastards on the planet! How do you like the Glorious Galaxy Note? I know I'm not on topic but I'm rolling with an Atrix 4g. The Galaxy Note blows my damn mind!!!!!!!
Sandisk 64gb is now 149 on best buy online. Otherwise amazon is the cheapest. Soon as best buy does 99 bucks I'm on that ****

Can anyone comment yet on the speeds they are getting with their internal microsd cards for read and write?
I would like to see if it is worth splashing out on an expensive high speed card, or because it is running USB2 that in real terms it is crippled to about 20MBps read/write. It would be a pitty if the speeds are crappy, as samsung is making some pretty sweet microsd cards these days.

ooops. you are right... a1 sd bench labels it wrong. It says Internal SD card as my external and my internal as my external. (Sorry)
Here's my new results - reading 40 MB/sec 14 MB/s write..
Once again - sorry about that.
Guys, when you say Class 10 you aren't really speaking to the speed of the card. There is a wide range of speeds in cards that are all rated as class 10. Samsung has some that are 90 read and 80 write for example and most only advertise as 30 read and don't even say their write. Anyone have one of Samsung's good 90/50 or 90/80 cards they have tested?
I have just benchmarked a 64GB Samsung Pro MicroSDXC card (rated at 90MB/s read, 80MB/s write). In a USB 3.0 card reader on my computer it writes at around 65MB/s average and reads at upwards of 80MB/s.
In the Tab S 8.4 (Wi-Fi only model) it benchmarks at 49.53MB/s read and 24.53MB/s write in A1 SD Bench
So what would anyone say... Is the best card for this particular device? Any recommendations?
If you're not planning on taking the MicroSD card out of the tablet in order to transfer content onto it, then you might as well just go for a mid-range card as it will be limited by USB 2.0 transfer speeds anyway. I'd say the Samsung Evo or the old Samsung Pro card would be fine depending on pricing.
I dont plan on taking it out. Since the above Benchmade had the pro at 49.53MB/s read. I feel It's just going to be overkill. Since its not getting the full 90 MB/s read 80MB/s write. I'm thinking the Evo should suffice. What are your thoughts?
I meant the old Pro model, which I think was 70MB/s Read - 20MB/s write, these can sometimes be had for similar money as the new Evo. I think you'd be fine with either of those, or even the Plus model. I think the Samsung MicroSDs are fairly reliable in general.
So nobody knows if Tab S has standard bus, high speed bus or Ultra High Speed Bus UHS-I or UHS-II?
I think that micro SD card Class 10 U3 guarantees minimum 30MB/s. So it supports even 4K recording...
But I still don't know if it is worth of a lot of money. If benchmarks are true - Tab S has UHS (your 45MB/s). If!

According to Samsung support, the Tab S micro SD speeds is limited by the USB 2.0 bus, or 60 MB/s. So that would imply UHS, though the 90MB/s cards would not get the full speed. I would like to see someone test a 90MB/s card and see what the results are. Probably just going to go with a 48MB/s card if there isn't any difference. Though I think write speeds are significantly different between the higher speed UHS-I cards and the lower speed ones (50 vs 10 MB/s write I think).
If anyone has a couple cards and a Tab S they can test with, I would love to see the results.
Tried searching, but coming up empty. Maybe I should have put this in the accessories section.
I need to buy a new micro-sd for my G3 I just got yesterday. I would love to pop for the 128gig Sandisk, but 120 bucks would allow me to buy five 64 gig cards. The only card I have right now is an older 8gig card coming out of my HTC Evo LTE so I definitely want something new and bigger.
Is the G3 physically capable of taking advantage of the cards with the 90 mpbs read/write rates of the higher end cards like the Samsung Pro series? Or would I not see any advantage over the slower 45 mbps cards like the Evo series? I know either card would work, but if the LG G3 is only capable of read/write speeds of 20-30 mbps, the faster card doesnt seem to be worth the money. I think I saw one test where somebody was getting around 19mbps of read/write speeds with one of the Sandisk cards capable of 90 mbps, so this tells me its not worth it to get a faster card for double the money.
This will store pictures and music and the occasional video so nothing crazy as far as use.
64 gig Evo series is 25 bucks, 64 gig Pro series is 50 bucks. The money doesnt matter to me, but if I cant use the capabilities its a wasted 25 bucks.
No, the G3 won't be able to take advantage of the UHS-I speeds. You'd have to remove the card from the phone and use a compatible USB3.0 card reader to see those 90MB/s speeds.
I bought a microsd 128gb for $18..i copied over 1000 songs to my phone in less than 30m

Are those graphs showing the built in memory speeds or a Micro SD card speeds?
So basically it looks like it wont be able to take advantage of the ultra fast 90 mbps cards so I should just save my money and get the mid level 45 mbps card. Done deal.
Yes that is showing the internal memory and not the micro sd. Get the cheaper version. If taking 4k record it to internal then transfer to external

It's showing internal, which may be slower than the Samsung Pro cards. I thought the G3 was UHS-1 capable Also, I'd like to know how that guy tested it. If he started loading some mkv videos than OF COURSE it was slower than advertised. Storage always is slower than advertised speeds at transferring compressed media.
On another note, it's MBps/MBPS which is very different than mbps op

The lowest a 128GB microSD has ever been is $99 a while back, regular retail is around $130. As of now, SanDisk is the only legit manufacturer. Never buy such stuff from eBay, and definitely not at such a low suspicious price of $18.
Sorry you got burned.

I'm happy to spend more if G3 can works fine and take advantage with the UHS-I at 30/95.
Is this is to confirm that the LG G3 is able to take advantage of the Micro-SD UHS-I speeds. W:30/R:95-Mbps............right?
Please advise, If I store a lot of Hi-Res images [3-5Mb/image] and some HD video files. Is it worth to go for UHS-I 30/95 or 30/30 is enough?
I'm thinking of
1. Toshiba EXCERIA 32G/Class-10/UHS-I @ 30/95Mbps. @ US $31.29
2. Toshiba 64G/Class-10/UHS-I @ 30/30Mbps @ US $32.59
Thnaks :")
I would say so. just performed a test copy of approx 267MB and below are some screenshots showing speeds.
first is Samsung pro 64MB to internal, second is internal to Samsung pro. it was peaking at over 30MB/sec to the SD card when copying photos earlier.

I wouldn't go for the 128GB just yet. The write and read speeds on them are horrendous!! I got a 64GB with 80 write and its fast as hell!

I found that increasing the SD card cache using the "Kernel Tuner **root**" app increases performance. setting to 4096 seems a good level. very slight change between there 6144, though no improvement setting it higher than 6144 in my testing.
SD card manages 33MB/sec write and 78MB/sec read.
internal improves to 70 write and 263 read too.
I noticed that ram tests were faster today. not sure if related to more free RAM, will test again later.

Any idea what speed MicroSD cards the HTC 10 will support? It'd be nice to get a high-spec UHS card to use the expandable storage! Coming from a Galaxy S4 and S2, my last HTC device was an HTC Desire - so I'm not sure what the previous generation of HTC devices supported.
I guess it supports U3, because A9 does.
Good to hear, looks like I'll be upgrading my MicroSD card then, thanks!
Great news. I have a U3 card but don't get the full benefit of it at the moment. When I searched for this information on precious phones I could never find anything!
I called HTC today to see if they could tell me if the HTC 10 will support UHS-II but after consulting with the build team they still did not understand what I was asking about so hopefully the full specs on the bus type for the memory card reader will be released soon. If anyone knows if HTC 10 supports UHS-II please comment as I am considering buying the new sandisk card or the samsung pro + U3 card depending on what the bus type is.

If you're getting Samsung Pro+ U3, you don't need UHS-II. Its specs are:
UHS-I / U3 / Class 10
Max. Read Speed: 95 MB/s
Max. Write Speed: 90 MB/s
It's a fast card. I got several 64 GBs when it was on sale for $28. The 128 GB version is available but almost double the price of slower 128GB cards, but still not a bad deal IMO.

Thank you for the response. I was going to get a UHS-II CARD if the HTC 10 used that bus. If they stick with the UHS-I then I was going to go with the samsung pro plus. Glad to here you like your card, I have read nothing but positive remarks on the samsung cards.
So which card (in terms of speed) to get for optimal user experience?
So I was anxiously waiting for HTC's reply about the UHS-I vs UHS-II.
Randomly looked at the SD820 specs five minutes ago. I'm feeling so dumb right now.

Storage
UFS 2.0
eMMC 5.1
SD 3.0 (UHS-I)

Well there's our answer.
And since the A9 supported UHS-I U3, the 10 will also support UHS-I U3.
It will NOT "fully" support UHS-II U3 cards, they will work (backwards compatibility) but you will not get the full speed benefit of them!
Maybe we'll get SD 4.0 (UHS-II) with Snapdragon 830 or whatever it will be called..

I'm going to assume you mean with Adoptable Storage "enabled".
Well, of course an UHS-I U3 card. Sure you can buy and use an UHS-II U3 card but there is no real benefit to that because the 10 fully supports only UHS-I U3. Also UHS-II U3 cards are really expensive..
For user experience, buy the microSD card with the fastest random 4K read and write speed possible.
Why "random 4K"? Because what we do on our devices is inherently random. Opening an app, updating an app, skipping music files and such. Only things that we do on our devices which are sequential in nature would be recording a video, taking a photo, downloading a large file and so on. (or transferring big files PC<>phone)
Sequential read/write speeds with SD cards (or SSD or HDD) are what's advertised most of the time and those speeds are already waaay more than enough so no need to focus on those aspects!
For example phones record 4K video usually at about 40-65Mbit/s which is 5-8.1MB/s. And that's sequential, not random.
That's about the heaviest sequential write operation we do on our phones. Downloading a large OS update could be "heavier" if you have really fast internet speed.
For random 4K read, I consider 10MB/s or above as really good. 8-9MB/s or below, I personally wouldn't bother.
For random 4K write, at least 1MB/s. 2MB/s is nice and above is excellent. (biggest impact=App install/update, OS update etc)
For speed reference and a reason for the above speed recommendations:
Anandtech's internal NAND random 4K speed tests from Galaxy S7 review part 1.
You can for example google "make model crystaldiskmark" and see the results.
If you don't find CrystalDiskMark results for some specific microSD card
a) don't bother because it's some random card
b) rummage through Newegg or Amazon etc buyer reviews. Occasionally some kind soul will benchmark his/her recent purchase and include the numbers in his/her review.
For example the Sandisk Extreme microSDXC 64GB is really nice

Kingston UHS-I U3 microSDXC 64GB also looks nice at the first glance but look at the random 4K write speed, that's horrendous! (don't even touch it with a ten foot pole)
Lexar 1800x microSDXC 64GB is one of the best I've ever seen. But it's so expensive (100€'s) ;(
Disclaimer: when you are looking at CrystalDiskMark results for 4K speed, do not look at the QD32 or Q32Tx numbers.
Only look at the 4K speed numbers that don't have the QD32 or Q32Tx text next to them, that's the number we are interested in.
QD stands for Queue Depth. Long story short: Queue Depth means how many read and/or write (I/O) operations are queue'd one after the other.
QD32 is a REALLY high and ridiculous number. You do not see that kind of queue depth with I/O operations on a phone, not on a PC, and heck, most of the time not even in servers either.
The speed number which does not have QD32 or Q32Tx text next to it means that the Queue Depth is 1. Only 1 read or write operation is queue'd. That's the normal kind of QD you see in phones or PC's.
so i ordered the 128gb Sandisk Ultra card... i know it is slightly slower than the Extreme range but I wanted more than 64gb to store all my music etc... will I actually notice any issues running this card rather than one of the faster ones?

For music listening I would say no. The difference will be when you want to save large files to and from the card. This is when the differences in speed per second add up over minutes when you are talking about gigabytes of data transfered.
In reality, this shouldn't be a big issue unless you are constantly moving big files. I guess the most relatable for me would be twrp backup to SD card. For a file of that size I would only imagine an extra 30 seconds to 1 minute so its still fine.

You will bottleneck in that scenario... But I would imagine it would be the WiFi causing the slow down rather than the card.
It will be most notable when downloading and uploading via a cable. Or saving to the card from the phone (like twrp which is generating data for the card rather than getting it from the USB cable or online).
I don't think you will have anything to worry about here buddy.
I wouldn't think it comes with a UHS-II bus since no phone in existence does.

If all you're doing is storing music and pictures on it, you won't see a problem. If you decide to use a slower card as expanded storage though, it's going to be a bottleneck for your applications.
I'm going to be doing some research into the fastest card the phone will support, methinks!

That should be the best one, you want u3. So SanDisk Extreme Pro UHS I - U3 Should be in the 40-50 dollar range for a 64gb. They don't make them any bigger.
