Could someone please try "SD Tools" and report you SD cards speeds. Im getting about 2.5 mb/s on both read and write. Tried several cards type 4 and 6. Cards reach full speeds when tested on a PC. Is that a limit for this phone or something is wrong with my unit? I had a Adata SD card die on me recently, too.. Could have been one of the fakes.
So, download and run "SD Tools" program on your i5800 and let me know the results. Also the type of sd card. I cant find any results on internet or this forum. I cant belive that i5800 is capped at 2.5 mb/s.
Thanks in advance everyone!
with the 1GB stock card, I got following result:
2.2 MB write speed
and
4.9 MB read speed.
8GB a-data
3,2 W
6,2 R
Hmm interesting. It seems something is wrong with my phone. I get 2.5 read on genuine 8GB class 4 sandisk card FAT32, at this moment. Thanks! Feel free to add the scores.
is it MB or mB, big difference!

Hope "SD tools" can be trusted for Galaxy 3? Guess its time to RMA the phone.
-3.4 MB/s for writing
-4.7 for reading
Ok here is the concluson. I just got a new Class 6 Transcend card to make sure. Phone is OK. I got around 5.5 on both read and write. This is my third card so far.
No1: A-data 8gb Class 6 - died after 3 months of use, was always slow around 2.5 MB/s. I suspect it to be fake!
No2: Sandisk 8gb Class 4 - slow scores like its a Class 2 card. Also 2.5 MB/s. Tested it and its not one of the fake cards. Bought at a big reliable store. It seems Sandisk has some Class 2 cards marked as Class 4. WTF! Hope to return it.
No3: Transcend 8gb Class 6 - finally working as it should! Transfer speeds up to specs. Actually getting close to Class 10 scores with adapter under windows?!
I was either very unlucky or the SD card market is really crazy right now. Im just glad I dont have to return my phone. Thanks everyone for results!
Transcend 8gb Class 6- read=5mb/s

Hi All,
Just got myself a 16GB version of one of these:
http://www.transcend-uk.com/Products/ModDetail.asp?ModNo=195&SpNo=1&LangNo=0
to replace the stock 8GB Class 2 card that came with the phone. Unpackaged carefully to avoid dribbling on it
Have run benchmarks using both SKTools and Pocket Mechanic and ..... approx 5% SLOWER than standard card!! Have got SDTuneUp loaded, am I missing something glaringly obvious here???
SKTools summary results:
8GB Class 2 Sandisk (supplied with phone):
Buffered Write speed 910 KB/s
Read speed 7119 KB/s
16GB Class 6 Transcend:
Write speed 859 KB/s
Read speed 7021 KB/s
Could the glaringly obvious thing be *don't buy Transcend cards* ??!!! Am I benchmarking with the wrong software (figures vary greatly between the 2 apps but summary is the same - this card is slower)
Any tweaks I'm missing?
Cheers.
Bones.
Is this with the card in the phone or in a card reader?
Most likely it's the limitation of the phone. Try some desktop benchmarks with a good card reader.
You won't gain much speed from higher speeds cards on a phone.

hmm so whats the point of buying a higher class SD card?
Benchmarked in phone. I'll try in my card reader tomorrow. Got to say I'd be very disappointed if it's a hardware limit in the phone, class 2 cards are much cheaper than class 6 and HTC should have made this apparent if this is the case...
Will update when re-benchmarked, anyone got an comparison stats?
one comparison Class 6 to Class 4
At hand a Transcend 16gb Class 6 and Toshiba 2gb Class 4 SD cards measured in Thinkpad card reader:
Crystal Disk Mark mb/s
Transcend/Toshiba
Seq: 14.78/12.11 read 8.755/5.315 write
512K: 14.76/12.09 read 1.982/2.010 write
4k: 3.114/3.216 read 0.025/0.025 write
Not much there to recommend Class 6
Are you sure you have 8GB class 2 sandisk card? I got class 6 with the ppc.
My results in SKTools:
write: 642 KB/sec
read: 2963 KB/sec
That's 16GB class 2 sandisk card formatted with 32KB clusters. So i think your card is ok
Double post
Class6 does not mean that its faster its just "assure" you it can transfer up to 6mb/s. Thats prolly a device limit and not the card you should try it on a notebook or card reader outside phone. I thought the same when i bought a 16gb sdhc class6 SD for my axim - had no changes in speed at all =\
Hey folks,
is there any Speed difference between a Micro SDHC Card with Class 2,4 or 6 while working with the HD2? For example loading big files like Navigation Software.
Copying things onto the Card is for sure much faster, but while copying i've time to wait. Intressting to me is just the speed difference while working with the phone.

I've got a class 2 16GB SanDisk card in mine, and if a class 4 or class 6 make operation time any quicker, then I seriously doubt that you'd notice it. I've not tried any other classes, so can't compare, but I can definitely say that a speed improvement is not required.
allright
a 16gig class 2 is ordered!
Depends on the storage size. With most 16GB cards, there's almost no difference between class 2,4,6.
The less the storage size, the greater the difference between the classes.
However, I recommend a quick test to make sure the data rates are acceptable, before you keep the card.
@johncmolyneux
what's your average speed with 16gig class2 (card in the HD2 and connected via USB)?
Would be great if you could make some Benchmarks with HDTune or HD2testw!
A friend of mine got an PNY Premium 16gig Class2 Card and he got:
~3MB/s Write
~8MB/s Read
(hd2testw)
i hope its the card that is limiting and not the HD2, because these values are bullsh*t!

Reading, I got 8.3MB/s, but couldn't try a write test as it wanted to remove the partition on the card. I then tried the same test with the 8GB Transcend card (class 6) that was in my HD, and I got around 50MB/s read on that.
It was definitely a noticable difference doing that test, but not a noticable difference when using the device.
Incidentally, I couldn't find a single thing about hd2testw. Do you have any links?
what? 50MB/s Read. thats stunning!
is the 16gig Card a SanDisk or also one of the "cheaper" producers?
Try ATTO Benchmark.
I'm now going to cancel the ordered card and get the SanDisk 16gig from amazon. Reviewers on amazon talking about 10MB/s write and up to 20MB/s read. Hopefully the HD2 can make same results!
These are both using ATTO Benchmark (8MB chunks, 256MB size).
16GB card is a SanDisk, class 2.
Write : 4 MB/s
Read : 8.6 MB/s
8GB is a Transcend, class 6.
Write : 6 MB/s
Read : 7.4 MB/s
I trust neither of the apps that I've used for these tests, as the results don't make any sense.

No offence, but I would be inclined to suspect your benchmarking software if it's claiming 50MB/s. That sort of speed suggests that all the reading and writing is actually being done to or from an in-RAM cache rather than the card itself.

32KB cluster size ?
What is the best cluster size to use for formatting a 16 gig card?
Hi Guys,
I have a strange situation going on here with my micro SDHC cards. I have an 8gb Sandisk card class 2 and I just bought a 16gb Duracell class 4 card as I wanted a bit more space than 8gb for my desire HD (to be arriving soon).
Anyway the 16gb card arrived today in the post so I was bored and decided to do some speed tests on the 2 cards just to check. The class 4 card wrote at 4.1 mb/s which I presume is what it should do...right? How ever the class 2 card wrote at 13.5 mb/s!! I tested it several times with large amounts of data (using the H2testw program) and it kept getting the same results.
So it lead me to think that there is something wrong with my class 4 card (or its a fake). It does write at 4 mb/s but that is the bare minimum and surely it should be doing better? I got it off ebay and am now aware of the extreme amount of fake cards on there.
Anyone with a little experience on the matter care to offer me some insight?
Btw I will be using my phone for pictures and 720p recording so I want a fast card...but after this I am just confused.
Thanks

Your card is just fine. The class of a memory card just tells you how slow it isn't, not how fast it can get.
Class 2 - Minimum of 2 MB/s performance.
Class 4 - Minimum of 4 MB/s performance.
Being a class 4, a minimum 4 MB/s is fine and passes the class 4 classification. But a 13.5 MB/s for a class 2 is great!
in my experience larger cards tend to be slower in real life situations anyway, i have found issues using slower cards so tend to stick with a minimum of class 6 (but then your class 2 exceeds that spec )
Hello.
I got a question to You about write/read speed in our I5800.
Because I bought micro sdhc 8gb class 10 card (GOODRAM) and I tested it in Antutu benchmark. Write/read was about 4.5-4.8 Mb/s.
But in PC I tested it and I have read:20 mb/s, write 12-14 mb/s.
So, I5800 can't handle class 10 card?
Please, write in this topic Your Antutu scores of SdCard (and which card and class You use)
Greetings.
Sent from my GT-I5800 using XDA App
Well the phone limits the read write speed somehow that s what I ve heard. Why don t you try the SDCard reading speed fix??
Because it may cause lag in playing videos. Or I'm not right?
Sent from my GT-I5800 using XDA App
just read in a german board that there is a conjunction of:
class and size
so:
a class 2 1GB may be faster than 16GB class10
and
class 6 may be the fastest that may be "supported" by the G3, so class 6 is the "fastest" really usable speed in G3 due to G3 bottleneck
all above is waste of money
just ordered class6
4, 8 and 16 GB
cards to verify theory above of speed and capacity in different sizes
keep you updated
Waiting your tests...

Hi,
I have class 4 SD card m running Pda's win7.8 rom. the problem I m facing is its lagging and slow then I did a benchmark test using free benchmark app everything is perfect except the write speed which is just 2.1 something, I know it may be a problem of SD card though wanted to know is there any tweak to speed it up through registry or app like andoirds have?
thankyou
no... buy better card...

can you guide me which type of card should i buy?
thankyou..
someone write this list but also many others cards is fine
Kingston 4GB Class 4
Kingston 8GB Class 4

Microcenter 16GB Class 2
SanDisk 8 GB Class 2
SanDisk 16 GB Class 2
SanDisk 16 GB Class 6
SanDisk 32 GB Class 2
i have SanDisk 32 GB Class 2 and speed is around 8 mb/s
Slower card makes
you wait longer,
gets your cpu hotter,
your battery drain faster,
lags the phone,
slow responses of your phone,
Go buy yourself a class10 SD card!
Believe me, if i knew the diffrence, i would buy it 3 years ago...
Thank-you dxdy and stealth21
will buy new SD and report back
