Hi, I have been searching on the forum in search of some information on MicroSD cards and came to no avail.
With my HD, it came with a 8GB Class 6 MicroSDHC. I think it needed it to play videos. I can't imagine using it with a slower card.
Now, my TP2 will arrive Monday and I would like to know the following:
1. Brand
2. Size
3. Speed (class)
4. Price
Is it performing well with the video playbacks or have you installed the SD Tuner software available for the HD?
What do you recommend?
Many, many thanks for any replies, comments and help!
Bought a A-Data microSD class 6, 4 GB at a local computer store.
Not the one i was looking for, i wanted the 8GB or 16GB but both where not in stock and the 4GB was less then 10 euros. I will buy a larger one in a few months.
With class 6 my phone isn't slowed down. A few years ago i bought a 2GB mini-SD, but my HTC Vox was slowed down very much. Didn't look to the class/or speed back then.
MicroSD cards based on SLC might be beter them MLC. IMHO i would always take a class 6 or higher card. However class 8 cards are hard to find.
I'm using the 8GB Class 4 card that came with my daughter's Nokia 5800 and it seems fine. Just watched an xdiv episode of Only Fools and Horses on it with no stutter or dropped frames.
I bought a class 6 off Ebay and it should be here on Monday so I can compare then
i'm using sandisk 8g class 2. whatched movies and played music, everything is fine. It only cost me just under tenner.
The performance diference between a class 2 or a class 6 is not that noticeable. However, at the price the cards are, I think it worths always to buy a class 6 card.
I bought a Transcend 8GB class 6 card. It cost me aprox. 20€.
The biggest differences I noticed between a class 2 and 6 card are:
-Taking photos is faster with class 6
-Browsing photos in sdcard is a bit faster also
-Viewing movies sometimes is a bit more smooth.
HastaSSSS
I have a 16GB class 2 Sandisk. I watch movies just fine. I figure with a class 6 i might be able to watch HD videos more smoothly.
Hi guys,
Thanks for all your replies. So from what you guys are telling me, it is always better to pay that little extra for the class 6 MicroSDs. But then again, is it worth investing in a 16GB Class 4 (no Class 6 available except the brand A-Data) or an 8GB Class 6.
16GB is nearly 4 times more expensive than the 8GB and yet it is slower. Shall I just get 2 8GB and hot swap the 2 cards as need be?
I bought a class 6 off Ebay and it should be here on Monday so I can compare then

I have read about this brand, and what others said was that their Class 6 under performs Sandisk's Class 4 Cards. Do yo notice any differences? How is the performance?
Also, I wouldn't recommend buying these cards off eBay. There are so many, fake cards on there. I know so, because I know mates that sell these cards. I would just buy from a genuine local store and pay a little bit more unless you don't care about performance.
Anyway, my last question.
What brand do you think has the best performance. Yeah, we can find out all the data about these cards on the web but it's nothing like the hands on tests from real users. So, will it be Sandisk, Transend, Toshiba, Kingston or the later A-Data?
Found a pretty review on the Sandisk 16GB C4 MicroSDHC cards. They compared it to the Kingston 8GB C4 MicroSDHC card.
Sandisk seems to be the company that is producing the fastest cards. It out performs Kingston.
But $133, is a bit steep. I think if I am correct a Sandisk 8GB C6 MicroSDHC is only $49.
What do you think?
You won't notice much difference between class 2 and class 6 as the device can only read at a certain speed, which is nearer class 4.
There are some cheap class 2 16gb cards out there, I have them and you only really notice if you install something like sdtuneup, but then again, you wouldn't notice much difference between class4 and class6
SanDisk microSDHC 16 GB Mobile Ultra works fine!
With the enclosed reader it is really fast via USB.

Cheers for the heads up about the TP2's read speed.
I was going to go for a 16GB class 2 but now might hold out for a class 4.
Haven't noticed any speed difference between my 8GB class 4 and 6 cards except that it's possibly slower than my Trinity but that may be due to the crummy TP2 stock ROM...

Please don't get two 8GB's, you will ruin the back cover of the device swapping the cards over all the time
My understanding is that the Class affects write speed, not read speed, so you won't see a difference playing movies on one or the other. You will see a difference in the amount of time it takes to get the movie onto the card (providing you aren't using ActiveSync, which will slow things down way beyond Class2 speeds).
I have a SanDisk Class 2 16 GB card on my Vogue and watch movies just fine with CorePlayer. Maybe a brief stutter once every 5 minutes or so, which I attribute to WinMo doing some other task in the background, not the read speed of the card.
In short, if it doesn't matter to you how long it takes to transfer large files onto the card, go with the least expensive.

Really? How much slower?
Yeah, I think I will go for 16GB for sure. The only thing now is what class. I am hearing 2 things here. I am worried about stutters on watching movies.
Some are saying speed only matters to write and not read.
But then I have read that it does matter, that is why there is a SDTuneUp for the HD.
I really don't want to buy a cheaper Class 2 card and only finding it is not working to my standards. I am pretty fussy about these things.
Any of you needed to install the SDTuneUp registry edit for the TP2? Do we need it? Anyone did any tests?

Check this out.
And this.
Class rating only refers to write speed, even though on the official SD association page it says "transfer speed." What they don't say is that it's transfer speed only one direction.

Hello ajbopp,
Thanks for your additional information. I think not a lot of people actually realise this. I always thought the Class Rating was how you determine transfer speed and not just write speed.
But there must be some ratings for Reading. Some cards are faster than others and that will certainly affect the rate of requiring information from the card, right? Because files are written in blocks and are distributed everywhere (fragmentation), so if the card is faster, then finding the blocks will be quicker, hence a better performance for reading movie files.
Just thinking logically how computer hard disk works. Not sure if that applies to SDHC cards. I also think the speed is also determined by the drive (the hardware reading/writing on the card).
There aren't many information on this. I have been searching around and most information I found was given by the companies that made these cards. Real tests are few and far between. Most websites I visited, tells me only of the write speed as I think that is what is most important to people who uses these cards, such as Photo Fanatics who needs speed for taking high end photos very quickly and for taking HD videos at 30fps. There is less need to know about read speed.
It's so confusing...
Got it yesterday. Thanks for all your help guys!
I finally went for the Transcend 8GB Class 6 Micro SDHC. Cost of only $187 HKD, roughly $23 USD. Didn't end up getting the 16GB as they didn't have any in stock and it costs 3 times the amount.
Without any tests, I just loaded my movies and it played very well. No dropped frames. No tweaks whatsoever.
Hello!
I had a TP with a Micro SD 8GB Class 2 card.
I'm considering buying a new one (lack of space available) and I wonder if I should consider a class 4 or 6...
I use the MicroSD to store software, pictures (camera), music (to listen), and some videos (to watch).
I don't intend to remove the microsd from the TP2 slot (have to remove the cover) so what I usually do is to connect via USB cable (data instead of AS).
So, transfering data like this will I notice difference with Class 2, 4 or 6?
I'd get a good price with this:
http://www.amazon.com/Kingston-Technology-SDC2-16GB-microSDHC/dp/B001RPD06I
is it good enough or should I buy a Sandisk or perhaps a Class 4 or 6?
Thanks
SanDisk and Kingston are both good manufactures.
Class 4 is faster than class 2 and class 6 is faster than class 4.
But on the other hand: class 4 cards need more power consumption than class 2 cards and class 6 cards need power consumption than class 4.
For this reason I bought 1 x 16gb class 4. That is the compromise of speed and power.

Again, this is only for write speed. I think it's an important distinction to make, especially if you are hoping for better video playback because of a faster card. The class of the card is not likely to have any impact on the device's performance, either video or anything else (other than file saving/writing operations).
so... for my kinda use there is no need for a class 6 right?
do you think a class 2 kingston MicroSD 16GB can be used for what I want?
playback music and some video... storage ... navigation?
I looked around but couldn't really find any info- Not sure if I worded my serach right so forgive me if this has been answered.
Does anyone know if there is any performance increase using a class 10 or higher card versus a class 6? A class 10 card is about $30 more, but i'm not sure if the Evo hardware has a limit where the extra speed of the card would provide diminishing returns-
I'm assuming there's a bus limit similar to a pc, so if class 6 is 6 MB/s and class 10 is 10MB/s, anyone know the max speed card you can use?
I'm looking at this card versus this card.
TYIA
I have the adata and haven't had any issues with it.
Anyone know what class the card that came with it is?? Can't seem to find the answer anywhere.

Class = Minimum speed
Often class 2 cards perform much better than their rating. My Samsung SD card that came with the phone is a class 2, but performs at around 5 mb/s. The read speed is sadly only around 12 mb/s.
I'm currently using a class 2 Polaroid 16 GB that writes at 7.4 mb/s and read at 20.3 mb/s.
edit: I also have a class 6 Maxell that only does 5.7/15, and a class 2 Sandisk that does 13/20. Just remember that class rating is the minimum speed and your mileage may vary.
Depends on the quality of the chip. If it's just some cheap card, it may be right on the cusp of class 10, or even below.
Sandisk is going to be your best bet for quality (as long as you make sure that it's genuine). Kingston is usually from what I've heard, a pretty safe bet. I don't know what speed limits the phone has, but I don't know why you'd really need anything over a class 6... At least a good quality class 6
Keep in mind that Class 2, 4, and 6 are the official ones. Unless something has recently changed, that's all the real classes that there are. Class 10 is just a marketing gimmick.
edit: it looks like they actually did add a class 10...news to me
I'm trying to decide if i should go for space, or speed.
For those of you that bought 32gb cards, are they class2? and if so do apps and such run off it fine, playing movies?
Class 6 is much more fast, and a class6 16gb card is still half the price as a class 2 32gb card.
Just looking for guidance here, do we need more then class2 for our phones.
Plan on putting movies and apps and stuff on the card.
I have a 16GB class 2 card in my Cappy, and I can play 720p video off it without a single stutter, and I never did install the lagfix, so class 2 SHOULD be fast enough, depending on what you want to do with it.
But right now, the cost of the 32GB cards is, I think, prohibitive. It costs > 3x what I can get a 16GB card for, and thus far, I have not filled my card yet.
I would go with a faster speed for the bigger size card, class 2 would be too slow if you are read/write onto it constantly; For the best bang of your buck, the Polaroid 16GB microSD (made in Japan by PNY) from Frys is going for under $20 (after rebate); Even though it is labeled as a Class 2 card, but under most SD benchmark app, it is detected as a Class 4 card (4.5 MB/s Write/15 MB/s Read under the 300MB file R/W test in SD Card Speed Test)
I would rather take a 2GB class 6 over a 32gb class 2. Class 2 is so unbelievably slow its unbearable. I use my phone as a usb drive very often. In my previous phone I had an 8gb class 2. It was so slow I thought the card was broken. So I RMAed it and the new one was the same. I realized that it just takes like 8min/gb to transfer to it. (and no its not faster in this phone)
Class 4 is standard, anything less is a waste of silicon and plastic.
Class 6 is about as fast as your average-quick USB thumb drive.
Yes class 2 is fast enough to run programs and play back video, but you'll spend a lifetime transferring those things.
Not worth it IMO. Get an 8gb class6 if cost is an issue. Also, don't go with any crappy random manufacturers. I find that a class 6 from 'craptasticMEM' is nowhere near the speeds it should be, and in fact usually slower than a clas 4 I have from kingston.
The class rating has nothing to do with playback speed, only write speed. Copying files is faster, but how often are you loading up your SD card from your computer?
I am using class 2 and it is recording video just fine. I am not sure why above poster claims "class 4 is standard" - that would imply that class 2 is sub-standard. It is not, it just has slower write speed.
Keep in mind that if you lay out the big bucks for a class 6 32GB card today, it will half the price in a few months.
Now in my HD Camcorder it requires Class 6 to record 1080P - our phones have no such requirement, so anything above class 2 will help in initial data transfer from PC - after that you may never, ever see any benefit.

Yes, sorry you're correct. Class 4 is standard in my gauge of memory cards/usb drives. All the classes "should" perform fine. The higher classes are obviously faster (with significant brand to brand variation). I find that they are faster at everything though. Not just write, but read as well. A class 6 card is as smooth as the internal memory in the captivate. A class 2 card is abysmal at everything (in my experience). I say class 4 is standard because class 2 is really bad...

It could be my blindness - not physically, but the ignorance of not having a class 4 or 6 to compare to my class 2. My class 2 works fine for me, but if the class 6 stuff gets cheap I will head on over to it.

its not healthy to lie
you guys are missing the fact that the class ratings are a MINIMUM rating. a lot of brands will perform MUCH faster than what they have printed on them. just saying something is class X is pretty much pointless. it's just a guideline that is being loosely followed. benchmark and move on
If your running apps off of your card than believe me there is noticable difference between a class 2 and a class 6, and yes dont go for a no name.

I don't believe you. It 100% fully depends on the card. Some class 2's are faster than class 6's. Ratings are lies.... benchmark ftw!
True that. Ive found significant differences by brand. However, there is definitely a noticeable difference between a class 2 and a class 6 card.
What you get depends on personal requirements more than anything else. Faster or more storage?
I know speeds are:
Class 4 - Minimum of 4 MB/s performance.
Class 6 - Minimum of 6 MB/s performance.
Class 10 - Minimum of 10 MB/s performance.
Can the Galaxy S even get up to class 10 if I go that route?
Yes, it matters a buttload.
Yes the Vibrant can make full use of the fastest chips out there.
Spend a few dollars more at Newegg and get a good chip from a known maker (Crucial, PNY, Micron, etc). The stuff is pretty cheap anyways....worth a few bucks just for piece of mind.
http://www.newegg.com/Product/Produ...00007962 600006209&IsNodeId=1&name=Micro SDHC
I'd suggest staying clear of Kingston and *possibly* Patriot.
I've nver seen Kingston stuff work as advertised and Patriot is a hit or miss at best.
Agree with n2ishun
I agree withn2ishun
Crucial and the other he mentioned are way more ereliable and have a better burst capacity (ability to write for shot periods of time faster than normal benchmark).
SD Memory Card basic breakout these are just averages i have in my phone a 16 gig card that claims 20+mb transfer rate never checked it but it is fast
Speed Class -2 Normal Bus I/F SD, miniSD, microSD
micro SDXC data rate less than 3 mb per sec
Speed Class - 4 6 HD ~ Full HD video recording above less than 7 mb per sec
Speed Class - 10 High Speed Bus I/F Full HD video recording 10 Greater than 10 mb per sec
UHS Speed Class 1 UHS-I Bus I/F HD TV Real time recording (only available on bigger cards)

I dont know much about phone memory. i'll be getting my first smart phone this week (vibrant). I followed the link and the only company you had listed that i saw was PNY and they only sold cards at class 4 speeds. So besides kingston and patriot are the other's ok? Centon had a few class 6 cards that i was looking at. Or perhaps i should be asking are there any other companies i should stay away from?
thanks in advance
A lot of brands are okay. Well, that is if you buy it from a legit retailer and not from ebay where there is a chance for you to get a fake one.
Sandisk, PNY, Kingston, Adata, Transcend (I have a class 6 one), Crucial, and etc. They are all about the same. Go to Newegg for reviews.
Ah ok.
thanks alot.

dont forget about meritline.com.
i get all my sd cards from there.

I wouldn't say "impatient" but sometimes we have better things to do than sit there and wait for a file to finish transferring. Especially big files.
Usually files don't really get big enough on phones for 4mbs to be a huge problem.
But I'm not going to argue with you, the faster the better definitely. The good thing is there usually isn't a big difference in price between the different classes if you're shopping in the right places either.
the stock card is a class 4. I have an 8GB class 6 from my G1 days when we were doing 3 partitions on one card (crazy to me now). Does it matter? Yeah... Is it worth spending a lot of money on? Matter of opinion... how much are you using the sd card for read/write? I use the internal memory most.
I can see speed being an issue if you're taking a lot of pictures and video and saving to SD card. I usually use my external just for music, so Class 2 is fine for that (still, wouldn't turn down a Class 6 card if the cost differential were slight).
ok im sorry, i just wanted to confirm something, i'm looking at a getting a new sdhc card, mine is a oem verizon sandisk 16 gb class 2. im looking into upgrading to a 32 gb. i have alota music, maps, cm rom backups etc, and im looking at moving most of my apps to the card.
from what i understand a class 2, 4, 10 dosent mean much difference in the phone, but when downloading files to a computer. i wanted to confirm that the class doesnt mean much in the phone's speed..... this will change which card i go with... sandisk class 2 32gb are roughly 60 bucks and i like the company cause ive never had a problem with them, however the store down the road frys has a wintec class 10 32 gb for 65 bucks.... just wanted to get your guys opinion.... especially since the lenex and kingston are 100 each... again im not talking about the brand im talking about the class
It will make a difference on how fast things on the sdcard load. For instance your gallery will load much faster with a higher class card. If you have apps installed on your sdcard then they will load faster and so on. Now with this being said I have a 16GB Wintech class 10 card and and Adata class 6 card. The Adata class 6 loads everything much faster than the Wintech. My guess as to why this happens is because Adata is simply a better brand than Wintech. Some people have gotten lucky with the Wintech Class 10 cards and some have not. Some Class 2 cards will read and write at class 6 speeds. Is it confusing...a little, but the higher the class for the most part the higher the speed. If you can find a good class 6 or class 10 card it will be worth it, but my advice is to stay away from the Wintech. I have heard also that the Kingston class 4 cards usually are much faster than what they are rated for. If you want cheap, go cheap, but IMO you usually get what you pay for and Kingston is probably the top brand when it comes to microsd cards.
That's not necessarily true. The class rating refers to the minimum write speed - it has nothing to do with the read speed. I recently upgraded to a 16GB class 10 card from an 8GB class 6 card.
The class 6 card got ~7 MB/s write and ~14 MB/s read in SDTools. The class 10 card gets ~11 MB/s write and ~9 MB/s read.
But in general, the higher the class the better the card will perform in your phone.
yeah, higher class cards are only really good if you stream a lot

i know this is only your opinion and im not trying to put you down or anything, but i do believe scandisk is top rated memory card.
i may be wrong, but im pretty sure they have lowest consumer complaints (about card dieing after a month or read and write speeds being slow, or whatever the consumer may complain about)
i have always used scandisk and i, myself would rate them to be the best, but thats just my opinion.
