Hello all,
Ive got a spare 16GB Micro SDHC card which i have swapped for the stock 2GB version that came with the Desire, but it is only a Class 2.
Having read that its best to use Class 6, should i shell out £50 for a new one, or will i not notice a difference in class ?
Dunno - I'm using a class 2 16gb card myself and I don't notice much slowdown if at all. I'm surprised these things haven't come down in price after two years... key thing is do you notice any slowdown with apps that access the SD card? like I say, I haven't thus far...

i read somwhere that class 4 is enough coz the phones do not support hihger speeds. class 6 will help you if you will take card to the card reader straight to the computer... it think

Thats what i ......... think. Im sure it only matters if its connected to the PC, and in that case i dont care.
I read it on another forum that i wont link too
Class 6 are almost double the price of Class 2.
You don't NEED to get one, I did use a Class 2 card for a few days and didn't have any problems.
Personally I am using a Class 6 now, as I regularly transfer a lot of big media files onto the card, so the extra speed is worth it for me.
If you don't fancy forking out though, you don't have to.
I totally agree, My desire came with a 4gb sandisk class memory card which I initially assumed was class 4 until I took the card out yesterday...connecting the desire to my pc and switching to usb drive mode, i am able to transfer my movies etc to the memory at +/- 8Meg per sec which is more than adequate enough for me...I was about to get a 16gb one but was thinking of getting the class 6 one until i discovered the one I currently have is class 2, so I just made up my mind and went for a class 2 16gb, saved me money....
They only refer to the write speed of the card, i came from a 8gb class 6 and now have a 16gb class 2 and notice no difference, only difference is the write speed from pc to card.
Even though i got a class 2 i still see 4-6mb/s so happy enough with that.
I have a class 10 16Gb card in phone. Read and write speeds seem to be limited to around 8Mb per second (copying uncompressed music). Using an adapter, the computer is able to copy at 14Mb+ using the same card.
They just seem a big outlay for nothing to me, lets face it the only big write time is when you transfer everything across from your previous card once the stuff is on there the write times really won't be much of a problem.
The main reason you will find people suggesting class 6 and above SD cards is due to "Apps to SD". For the Newbies "Apps to SD" or A2SD is a modification that has been done on most android phones (though not the desire at time of writing) which allows the Apps you download to be stored on the SD card rather than the phones limited internal memory. I am not sure if it makes a huge difference to the faster processor phones, but in the G1 days it was noticeable. For just moving music and pictures about it isn't really important to have a faster card and we may have to wait a while for A2SD anyway. I will pop over to the N1 forum and see if they can shed some light on this.
Anyone using a microSD 16GB Class 4, if so are they any good? I'm looking at buying one for the Desire. Also where's the best place to get a deal on one of these card?
I'm serious about my portable music and am trying to find the best combination of Xperia phone and SD to match an iPod Classic in file transfer speed and audio quality but I'm mostly concerned with data transfer for now.
I'm using a class 4 32GB Sandisk and want to shoot myself :crying:
My iPod Classic laughs at the speed. :crying:
Anyone using a Class 10 or any kind of Ultra SD? How's that going? Do you own/owned any portable music devices like an iPod to compare with? All I know is my Classic can transfer at least 1 song per second, usually more, with over 32GBs of music that's great or if just transferring my newest 30 songs. With my class 4 SD in my Xperia it takes about 4-5 seconds per song and I would prefer to bounce it off the wall :fingers-crossed: :good:
I'm planning to get the Xperia Sola and upgrading my SD, (upgrading headphones after that) but I'm just looking for feedback?

Use a microSD USB adapter or SDcard adapter to get 10Mb/s, if I do use the usb cable the speed is like 2mb/s
I use a Samsung Class 10 32GB SD and the speeds are very Good.

I don't get it. What's so bad about class 4 microSD cards? I use Sandisk 16GB Class 4 aswell, I don't cry about lag, because I don't have it. Transferring songs isn't that slow, I don't do it often either so no problems with it.
Or is it just that people keep wanting more and more?

Is it just that people don't read entire posts?
As I posted above already, the issue is that I've been using various dedicated media devices for years which have consistently performed at far higher data transfer speeds. I'll say it again:
I have 32GB of music, if I transfer with an Apple device it transfers at least 1 song per second. For a large music collection, it does this very quickly as you can see. If I'm transferring the newest 20 or 30 songs in my collection, it does that in about 30 35 seconds.
If I asked my last phone or my current Android phone to do this, it takes about 4-5 seconds to transfer ONE song (or podcast). Whether it's a few minutes for just a few songs, or a few hours to transfer my whole collection, it's terrible performance and tedious.
Which brings me to my question about data speeds. I'm sure someone suggested before that it could be partly Apple cables being designed for optimum transfer speeds. I completely forgot about SD classes though, and I found the Sandisk Class 10 Ultra transfer up to 30mbps. I checked on eBay and they are not that expensive - about €30 for for 32GB. I'll get that soon and report back!
p.s. I just asked Sony about this and they said they've tested classes 2 and 4 with their phones and said that a class 10 will likely not work with their phones so not to purchase! Hmm. Mind you, many people here have bought 64GB SD cards when Sony said 32GB is the highest that you should use. I'll find someone here using a class 10!

One of the problems - the chip. Phone's motherboard and it's transfer speed. It takes a longer 'distance' for the data to travel - from the computer, through the cable, through the chip, onto the SD.
Apple devices don't use SD cards, they have built-in memory chips, which have a lot faster r/w speeds, also they use the full max speed of USB 2.0(35 megabytes per second), microUSB has a bit lower rate of speed, and certain compression to transfer faster, which doesn't happen on other devices.
On the internet, there are sometimes written only maximum speeds(like you said - up to). The Class shows only minimum speed, Class 10 having minimum of 10 MB/s for write operation.
Android devices are not the same as Apple. Everything can't be the same, because it has been built different.
And FYI, I did read the whole post.
Thank you very much for explaining that :fingers-crossed: - that was exactly the extra kind of detail I wanted to understand the technology better - which in turn allows me to make better purchases.
What is roughly speaking, the best performance you can achieve with Android using an SD? What is the best performance a micro-USB can provide? On my new laptop, I made sure to get a USB 3.0 port but I'm guessing I won't be able to use that with Android until compatible devices are released. Devices with on-board storage as large as I'd like are uncommon and very expensive, so SD it is. Would a class 10 SD be the best you could get? I would be happy with a slight decrease in Apple-type performance, but 1 song every 4-5 seconds is too bad. Essentially, what I'm trying to do is to integrate my phone and media player in one device, without paying a fortune for an iPhone.
I just found this thread with some of the same intention: http://forum.xda-developers.com/showthread.php?t=1674373
Perhaps, better micro USB cable such as: http://www.monstercable.com/productdisplay.asp?pin=4989 + class 10 SD = mission kind of accomplished?

A 32GB Class 10 SDHC is the largest and fastest kind of SD card compatible with Arc/Arc S. Some people have had luck with larger cards, but officially SDXC isn't supported on 2011 Xperia phones.
Phones currently don't support USB 3.0 as they don't have the processing power or data bandwidth to support USB 3.0 transfer speeds. You're hard pressed to find anything that maxes out USB 2.0 apart from dedicated storage - the two devices that exceed USB 2.0 speeds that I own are an external hard drive and a card reader that I use with high-speed CompactFlash. I usually get 10MB/s writes using this with my Class 10 MicroSD.
To be honest, trying to write at high speeds through the phone's system is an exercise in futility - just get a good card reader, it doesn't have to be a USB 3.0 model (which are usually rather expensive and aimed at photographers) as SDHC maxes out around 10-12MB/s writes anyway.
I got a 32 GB class 10 card with my phone when I got it. I move all apps to SD as much as possible, and also listen to a lot of music. I also take a lot of pictures and videos. So for me it was just calculated in as part of the cost of the phone when I bought it - it was a no-brainer.

You lucky thing, a 32GB class 10 SD with the phone? Hah that's great. Well how do you like the performance?
My plan is: new phone with excellent audio tech+class 10 SD+great earphones=very happy me. I'll have the phone next week, finally.
So I have a 32 GB Class 6 and runs well
YEs i used 32GB class 10 in my neo v, but you always to fomrat it when you put it in your device
I've a 16 gb class 10 Samsung sd, and run's fine whithout problems.

Well I have the same card, and I never managed to cross 7MB/s, with large files, music or videos. Not on my old system, not on my new system. Not on Windows XP, not on Ubuntu, not on Windows 7. Not on 6 different USB ports on my old system, and not on 8 USB ports on my new system. Two different USB cables are tested also.
So I'm really curious to know how could anyone manage to get 15MB/s with this phone.
Do you mind to post screenshot while transferring data at 15MB/s?

Ok, i dont know if all you are really using Original Sony USB cable or one chinese and cheaper, due to a posible damage on original one, i only posted for info.
Check write/read speed, tested with Antutu benchmark.
Like I said earlier, card is SanDisk class 10, 16GB.
I'm using 32 GB Ultra High Speed (UHS-I) microSD, works fine
also i've got cute micro adaptor with it for fast downloading from PC
my AnTuTu scores 5624
Has anyone found a inexpensive yet fast Micro Sd card reader?
I just got a Sandisk 64GB and would love to find something that could reader and transfer files to it as quick as possible. I looked at DX.com but a few units mentioned slow speeds. Anyone have any they can vouch for?
I have a Sandisk 64GB and several reader/transfer USB devices. All of them tell me the SD needs to be formatted. My SGS3 accepts media file transfers on the card though. All my readers can read my 32GB SD cards and transfer files with no problems at all. How are you getting files (other than media) to transfer between your PC and 64GB SD card at any speed, even slow?
* * *
Figured it out after reading more SD card posts...
My XP laptop needed an MS update to read exfat. Got it and everything works now.
I got this one from Amazon when it was on sale for $28 as the lightning deal of the day.
http://www.amazon.com/gp/product/B00A4A1TYM/
It comes with a USB 3.0 SuperSpeed microSD card reader (that just sweetened the deal) best of all, this card is rated a UHS I class 300x
I would have gone with 64GB but I'm glad I didn't since you have to hack your ROM to use it as your internal storage on Samsung devices. This is one thing HTC does right atleast. They let you combine your storage, why can't Samsung do the same...
the speeds are very impressive though, it outperforms my Class 10 8gb microSD
I get 41 MB/s read and 24 MB/s write (with the USB 3.0 jack)
with USB 2.0 it cuts those speeds down in half
HELLO FRIENDS
I HAVE N7100 AND OVER 1 YEAR I HAD 32GB MICRO SD CALSS 10
I HAD 13MB\S WRITE SPEED AND EVERYTHING WAS GREAT
LAST MONTH I HAD TO USE MORE THEN 40GB SO I Bought SANDISK 64GB MICRO SDXC
I FORMATED IT TO EXFAT AND THE DEVICE WORKS GREAT WITH HIM
BUT WHEN I CONNECTING THE DEVICE TO PC THE WRITE SPEED IS 7MB\S
AND WHEN I OPEN THE GALLERY APP IN THE DEVICE -- THE PICTURES LOADS VERY SLOW...
THE CARD IS GENUINE AND ORIGINAL
WHAT CAN I DO?

When connecting the device via USB cable, don't expect the transfer speeds to be that great. MTP is the default transfer protocol if you didn't change it. If you need to move files off of your MicroSD card quickly, its best to remove the media card from the Note 2 and put it into a card reader. As for the gallery app on the device, from what I have experienced is if you are using the card for the first few times it may take some time for the picture thumb nails to enumerate completely, especially when you have a lot of photos/videos.
This is purely from experience. I hope this helps a bit.

?????????????????????
I have tried two SD card in my phone now.
They work fine when not in use but if I write to the card the performance is abysmal.
The cards were Samsung 64GB UHS1 class 3 100MB/s. (Not slow cards).
When I write to the SD card from the phone or my external nas or a download. The homescreen performance is unbelievably laggy. When it stops it's fine. No apps are stored to the SD card either.
When I put the cards in my PC. They will write at 50MB/s all day long, in my phone they hit about 20MB/s for a small period then drop to 5-6MB/s.
When I run A1 SD Card benchmark my write speed for my SD Card was 8MB/s. On my PC it's much faster.
Can anyone try something similar? Download a 500MB file that saves directly to their SD Card. Even if I download an album directly to SD from spotify I get lag on the homescreen.
did the sd card benchmark, the top one, that matched the size of my card in a1
my results are 75.69mb read and 59.76 write on my s9, card pulled from my s7 and plopped in the new phone as is.
64g samsung pro plus
let me know about specific testing, new to the app, but already had it installed.

So I just left it and it's okay now. Maybe it was doing something in the background. Managing 50MB/s writes and not lags on the homescreen, not sure what was going on!
