Transcend 16GB Class *6* Micro SDHC Speed Test

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 =\

Speed difference while working with SDHC Class 2,4 or 6?

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.

What is the best cluster size to use for formatting a 16 gig card?

[Q] Testing the i5800 card speed

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
- write-4mb/s

Write = 3.7 MB/s
Read = 17.5 MB/s

Benchmark thread for best sd card for running android

THIS THREAD HAS BEEN CONVERTED TO THE FUNCTION OF RECORDING INFORMATION ABOUT MICROSD CARD BENCHAMARK AND ANDROID ROM PERFORMANCE ON THE SD CARD.FROM NOW ON REPORT YOUR BENCHMARK TOGHETHER WITH THE INFORMATION ABOUT WHICH ROM YOU HAVE INSTALLED AND HOW IT WORK ( LAGS ECC. ) PERSONALLY I SUGGEST TO TRY WITH THIS ONE : http://forum.xda-developers.com/showthread.php?t=954030
1) FOR THE BENCHMARK USE THIS : http://www.hdtune.com/files/hdtune_255.exe TO CHECK ACCESS TIME
2)THEN USE THIS TO AND RUN TEST OF 50 MB AND 500 MB TO CHECK RANDOM READ AND OTHER STUFF : http://crystalmark.info/software/CrystalDiskMark/index-e.html
Also use this app from the market ( it's free ) to improve read speed https://market.android.com/details?id=com.sdincrease.it . Anyway this is about daily use on your android ROM, it doesn't interfere with the test that you can run on your computer !
Original first post :
Hi all !
I was looking for a good memory card to use for booting android from memory card, expecially I was interested in the desire hd build which I know are the slowest one. I hope that a class 10 micro sd with a good access time can solve the speed problem .
I have selected those microsd as I don't want to spend more that 30 euro :
1) http://www.amazon.co.uk/Patriot-Cla...1?ie=UTF8&s=electronics&qid=1303572216&sr=8-1

4) http://cgi.ebay.it/ws/eBayISAPI.dll...109247&ssPageName=STRK:MEWAX:IT#ht_4103wt_905
any suggest ?

My advice to you is: check online the benchmarks and tests to SD cards, you don't need a class 10th SD card, it probably will be slower on Android than a class 2, because class 10 SD cards have a huge sequential data speed but a low random write/read, search for random access benchmarks and buy your SD from a reliable seller, carefull with eBay fakes..

Agreed! You may not need Class 10 micro SD as random access speed is much important. Besides, the power consumption of micro SD is also important for running Android on SD. For your info.,
-- normal max. power consumption of KingMax Class 4/6 micro SD is 60mA
-- normal max. power consumption of Toshiba Class 4 micro SD is 80mA
-- normal max. power consumption of Transcend Class 4/6 micro SD is 100mA
-- ......
You can search to find more info. about power consumption of micro SD. As these info. is from official site, which micro SD is the balance between performance and power consumption is required to be tested on HD2.

get the Adata is the best purchase you can do read write 20 mb 16 mb

I see, thanks you all for those advise, anyway I need a 16 gb microsd because now Ihave a 8gb and it's full and I don't know if 16gb class 6 exists !!!
Also my memory is a "team" 8gb class 6 micro sd and I think that it has a bad random access as android never runs well on it...Sadly I don't think that I can find benchmark for those memory card and expecially benchmark of people that are using them to run android.
Also on the productors site there aren't any data on the random access !!

You can use a program called crystalmark to test every aspects of the SD card.. its very good, if you want I can put here my results with my 8gb and 16gb cards..

yeah it would be nice ! Also indicate the brand of the cards !

my "team" micro sd has an access time ov 2.2 ms ...too high !!
I have seen this http://www.androidiani.com/forum/htc-hero/9327-microsd-16gb-classe-6-benchmark.html years better !!

I was just about to do a search on this.
I just want the "best" sd card for a reasonable amount of money (let's say max 200 Euro).
What do you recommend? I don't really need more than 16 GB but I want speed and safety.
What do you think of: Sandisk Sdhc Extreme Pro - 16gb, 45 MB/s?
All input is appreciated!
Cheers,
Patrick

I've used both a Kingston 8GB class 2 and an Adata 16GB class 2 without any issues. Will buy a Kingston 16GB class 4 in the near future. From comments, it seems to be a good card.

not really, kingstone has bad access time from what I have read on the internet..
So your patriot LX 16 gb class 10 is unsuble ? I was thinking to buy just that !!!
Why don't you try to do a hdtune 2.55 test ? it takes 2 minute..so we can see you access time ! ( for the patriot and the a-data ! )

Burst Rate: 14.2 MB/sec
CU Usage: 23.8%

The issue with the Patriot 16GB card is that I was consistently getting errors after 24-48 hours of use. That has never happened with the other two cards. I can see that the differences between the Kingston 8GB and the Patriot are very small. Obviously, the Adata is less impressive, but 18% on speed and 25% on access time is acceptable if the card is solid. Any suggestions re the Patriot card? Obviously, it was expensive and it would be nice to be able to use it.

well I have write wrong ! I was referring to the access time !! HDtune do not show random access !! By the way your patriot sd is not bad at all also if I have to say that A-data is most impressive because it's a class 2 and has spec of a class 10 !
AH maybe this is your are lucky! I know what's the problem with your patriot SD card, I have read this yesterday. Try this and your patriot card will work wihout any problems : http://forum.xda-developers.com/showthread.php?t=1010228 you have to format it without the LBA protocoll then you can use it with android !

I have selected those microsd as I don't want to spend more that 30 euro :
1) http://www.amazon.co.uk/Patriot-Cla...1?ie=UTF8&s=electronics&qid=1303572216&sr=8-1
2) http://www.play.com/Mobiles/Mobile/...source=9593&_$ja=tsid:11853|prd:88610&cur=258
3 ) http://www.kmelektronik.de/shop/ind...8&Ref=104&gp=4653&fd=608294&ID2=9007765597179

any suggest ?

Do not buy number 1 - Patriot LX class 10. I bought two of them and have terrible results - some androids do not boot at all, constant cash files, error files on the card, often files become unreadable and you can't delete them anymore and have to format the card - not good at all. Now ordered a class 6 card that's 38 dollars more expensive than this Patriot class 10 card

[Q] Question about microsdhc

I've got a while ago a Samsung 32gb PLUS microsdhc class 10 UHS-1...blah blah blah
I didn't pay attention to speeds before, but i was reading something about last night, and i checked on mine.
This card is advertised to reach up to 48mbps (read)
I tested on my s4 and the results was:
SD Tools:
Writing speed: 12.2 mb/s
Read speed: 19.7 mb/s
A1 SD Bench:
Writing speed: 14.60 mb/s
Read speed: 18.60 mb/s
My question is to someone who knows a bit about those memory cards and have some experience with them..
Did i get a fake one? Or the speeds above are normally for this type of card?

Anyone?

I think our phones can't handle more than 20MB write and read speed but on the computer, it may be faster. If you want to check if your microSD card is genuine then use H2TestW on your computer to test the card

Oh yes our phones has much higher reading/writing speeds.
For an example:
Internal phone card:
read: 81.42 mbps
write: 33.33 mbps
This is a quick test on A1 SD Bench.
So i would like to know from someone who knows better those cards if is normal.
I know that fake ones will not get writing speeds over 10mbps anyway, but i want to be sure.
Thanks

There is at least one similar thread.
Your speeds are the same as everyone else's. Don't worry, your card is ok.
Is the phone that is not able to use the full speed that the card can achieve.
