16GB Micro SDHC card reading speed - HD2 Accessories

Hi,
I have recently purchased a PNY 16GB micro SD card from play.com, marked as class 2; the strange thing is that the card came without the PNY brand and that made me a bit suspicious... it is marked C16G "Made in Japan", it looks like a Toshiba...
Anyways I did few tests and I got a writing speed of around 4-5MB/s , however the reading speed (tested with freeware HD Tach) is peaking only at 8MB/s where with my old 8GB card I can get 30MB/s at peak.
The tests have been performed on my PC using the HD2 in mass storage mode.
Has anybody bought the same card from Play?
What speed do you get with your memory card (tested in the same way)?
Thanks

speeds sound about right on a mobile device, i am not sure how you managed to get 30MB on a mobile as that is like 'unreal' speeds. For a desktop bechmark that seems fair but not in a mobile.

I made a test with a different software and I get the same writing/reading speeds. Note that the 8GB card is class 4.
Unfortunately I cannot use a desktop card reader for benchmark as the one I have got it's very slow.
Hence the reason for asking other people to test their memory cards on their phone.
Thanks

8GB Adata SDHC Card

I'm presently running Toflock WM6 and wanted to install the biggest possible SD card so I can put TT6 UK & Europe plus tons of other stuff without swapping cards.
I was advised in the Hima forum that there were SDHC patches which would enable SDHC. So based on this advice I just bought an Adata 8GB card.
I've tried several patches and nothing works, even the non-HC cards stop working and I have to re-install the Extrom prog to bring it back
So has anyone managed to get a class 6 SHDC card running yet ? If so with what rom etc.
Thanks
i am sorry to tell u this but SDHC is not possible on any Hima YET !!..i released 2 or maybe 3 Patches my self but none of them work...users cant even run 4GB and u bought 8GB..hope its refundable
Okay, I'll just have to keep an eye out for threads about SDHC updates.
In the meantime the Adata 8GB SDHC card will have to serve as a healthy sized flash drive to swap movies / mp3s with friends/family etc.
I've noticed 'non-SDHC' 4gb 50x speed cards on ebay. Has anyone got positive experience of slower speed 4GB cards like this??

Forget it.
Decent 4 GB SD cards from well known manufacturers cost approx. 20 €/$
There is no need for this cheap crap.

how? and what product?

Yes, i'm sure!
It's a Transcend card
I've got an A-Data 4-Gb, pink stiker (it says: myflash, 150x turbo SD 4gb Adata) and it's working well (sure not at 150x, maybe 1x ). To be fair, I have tryed several ones diferent sizes and the bigger they are slower they work, not only on the PDA but in the PC as well.
Have you testet read/write access to the whole 4gb? As far as I know, you can use these cards, but you have no access beyond 2gb.
4GB CARD
I am working with Transcend 4GB Card and the speed is great , No problem at all.
I also use a Transcend 4GB SD and it works great. You can access the full 4Gb. I watch many tv series in my himalaya with tcpmp.
As I said full access to the 4Gb card. I used to travel with my 100Gb 2,5 USB HD, some times I thinks it's a shame there is no app to get acess to it through a kind o USB cable, wuold you imagine?

Memory card advice wanted

Hi,
I've just received my TyTn II and am interested in getting a memory card for it.
It takes Micro SD but what is the max size that it/WM6 will work with?
Also, what is Micro SDHC? and can I use it?
I've seen a 2GB MicroSD card for £7.55 del. but I probably want a bigger card.
I intend using it for tomtom - photos - some games and apps and of course data file storage.
TIA
Bryan
I picked up a SanDisk 8GB via Amazon for under $70 USD (minus shipping).
http://www.amazon.com/Sandisk-Micro...1?ie=UTF8&s=electronics&qid=1204123335&sr=8-1
I have a San Disk 8gig in mine and it's great.
Cheers, Paul
Thanks for the quick replies,
As you are using 8GB cards they must be MicroSDHC? AFAIK MicroSD cards that hold 4GB or greater are all MicroSDHC.
Any chance you can pop your card and see?
The 8Gb SanDisk that I ordered is MicroSDHC (a.k.a. 2.0).
The HC stands for High Capacity and it is indeed for cards above 4 GB.
The device for the memory card has to be HC capable and lucky for us, our Kaiser is
Every micro sd card also has a class (2, 4 or 6 I believe). The higher the number, the better transfer rates (and response time), but also the bigger the cost.
I currently have a 6 GB (class 4) micro SD card. I'm going to wait a while to buy a new one until cards with about 16 GB or 32 GB (or something like that) of memory come around.
I'm also running the sandisk 8gb SDHC card. Its speedy and
works flawlessly. I got it on amazon for about 80 USD
The only thing i could recommend after having a card this big
is a good card exporting program on your phone so not
limited by activesync
Thanks for the help.
The 2GB MicroSD card at £7.55 seems very good value but I'll wait for an 8GB MicroSDHC deal to come along.
Hopefully a faster variant too..
Is it possible to connect the phone to a PC and have it recognised as a large memory stick? I know some phones do and then you can just explore them like a disc drive.
I will setup activesync at home for normal installation etc. but wondered if I could access the SD card whilst in phone from the PC/USB a la memory stick whilst at work.
yes, you can access the SD card like it's a memory stick by exploring. However, the transfer rate isn't as good as a USB connection with a stick. The 8GB SanDisk comes with a USB reader so that the card can actually be used in the reader just like a stick. Fastest transfer rate I've ever gotten with my phone
I'm using an 8Gb SanDisk MicroSDHC.
Works great!
I have a 8gb and it is fine.. but if you wait until next month you can pick up a 12gb and really have some storage space.

Talk about a deal i just purchased two 8gb for $70 because they were used and only came with one adapter.
I got my 8 gb sandisk sdhc card on ebay - another place to look for a great deal. Just be careful about the track record of the seller. I love the 8 gb card, but will be looking for a 16 gb card when they come out.
i saw the 16GB ones out anyone tried if it will work with the kaiser???
I run a Kingston 8GB SDHC in mine without problems (brought it over from my SDHC enabled Orbit), which I bought for £25 about 8 months ago from mobymemory. Never had any problems with it at all.

Can the HD2 benefit from class 6 SD? Or is it a bottleneck >Class 2?

I ordered a class 6 16gb card to replace the slow-ass class 2 8GB card I had in my HD2.
First of all I couldnt find the format sd tool in my energy rom (1st July) so I had to format the card using vista while the HD2 was connected in disk drive mode. THAT TOOK OVER 1 HOUR.
(Is there a cab file to install the "Format SD Card" tool for the newer energyroms?)
Anyways after formatting (Fat 32, 16KB cluster), I started to copy my 1.4GB sd backup file to the card using the same method as above (disk drive mode)....
My maximum write speed was 2.7MB/sec. Average 2MB/sec.
Class 2 speeds????
After restoring the backup, which took forever, I ran spb benchmark on the card and was gutted to get slightly lower results than the old class 2 I was replacing.
Can the HD2 make use of anything faster than a class 2 card?
Has anyone here tested a class 6 or even 4 card and found good write speeds (~6MB/sec, or ~4MB/sec)?
Does it sound like I have bought a lemon (class 2 labelled as class 6)?
I have spoken to the seller and he is adamant that they ARE genuine class 6. Reckons he tested some of the batch in TrueHD cameras which will not accept <Class6. Seems genuine and some of his feedback states that the cards are Genuine class 6. Which leads me to think that the bottleneck could be the HD2... Does that sound likely?
I'm waiting for a microsd USB reader to arrive so I can test the card outside of the HD2, but Until I can do that... can anyone tell me if a class 6 is wasted in a HD2?
The strange thing is that when browsing photos/wallpapers etc, the thumbnails ARE loading maybe 3x quicker than my old class 2. So I'm pretty confused about this one.
Can anyone shed any light here? Feel free to post benchmark results/screenshots etc.
Thanks in advance.
can anyone PLEASE answer this ^^^?
Is there any point having a class 6 card in the HD2 instead of a class 2 or 4 card?
there is a thread in the accessories section have a gander in there, I no this is Q&A's but lots of talk about mem cards in the accessories section mate
Cheers mate, I'll take a look.
I will move this thread there. I also recently bought a Class 6 card and and have seen a huge improvement in media reading and over all performence.
I get 4-5MB/s both for reads writes with my 16GB class 6 card in disk drive mode.
Thanks zelendel and kilrah.

That is exactly the kind of data I'm looking to compare.
Whith my 'class 6' Im getting just under 3MB/S WRITE and under 6MB/S READ when using the HD2 in disk drive mode.
If I use the card in a USB 2.0 reader I can get around 5.5MB/S Write and ~11-13MB/S read.
Based on this alone would you say my card is a class 6 or not. I'm beginning to think it may be a class 4 re-labelled.
Picture browsing etc is faster with my class 6 but all benchmarks indicate it is identical speed to my genuine Kingston Class 2.
What do you guys reckon, Should I send this card back for a refund???
Well if you're getting 5.5 and over 11MB per second with a card reader then we can safely assume it's class 6. The bottleneck is something to do with the phone, rom, cable or simply the phone doesn't like this particular card etc...
EDIT: Test your class 2 card with the memory card reader and see if you get similar results.

Thank you for helping me clear things up.
Comparing the 'class 6' and the 'class 2' transfer speeds is where I really get confused here.
Transferring a ~700MB .Avi to and from SD using a reader:
Kingston Class 2 8GB:
Read 12.5MB/s
Write 5.4MB/s
Unbranded Class 6 16GB:
Read 12.5MB/s
Write 6MB/s
So, from this, would you say its safe to assume:
1. The class 2 card is a good one, performing at almost class 6 speeds.
2. The class 6 card is 'Genuine' and shouldnt be returned.
3. There is a bottleneck when using the HD2 as a card reader/disk drive. I should be getting more than 2.5mb/s write speeds in this mode.
4? Does 12.5MB/sec sound close to USB 1.1 speeds? could my reader or even USB port (Vista laptop) be another bottleneck?
Once again thank you for helping me make sense of all this.
At least I now know that the 16gb card doesnt really need to be returned.
Can you give me your oppinions on the above?
Well class 2 means you should be getting a minimum 2MB/s speeds and class 6 means you should be getting a minimum 6MB/s.
Seems like you have a very good class 2 card.
More info here
http://en.wikipedia.org/wiki/Secure_Digital
Your class 6 is performing to spec.
Personally I would never buy an unbranded card but that's me. A branded card may perform better than there class rating e.g. Your Kingston brand I've always used Sandisk personally...
I've just managed to drum up enough funds to get myself a HD2 and now looking to upgrade my HCSD card to 16GB. To get the "right" class I tried to find the spec on the SD interface but I cannot find anything and the best data I can find is that I shouldn't waste my money on unbranded devices, I would always buy a SANDISK device for something I relied on! For data and communication!
People seem to get appropriate speeds for the class of device they have, if they are branded and sometimes if unbranded. However, there doesn't seem to be anything better than class 6 results debated or given. Is it a VERY rash assumption that the fastest the HD2 interface can go is Class 6?
Chris
Does this mean its not worth getting 32gb cos its a class2
& theat would make the phone slower cos lot more stuff on it
& will take more loading time & play Videos lagy ?
anyone useing 32gb ?
Thanks
My experience was positive with higher class micro SD.
At first, I used 8GB micro SD bundled with my HD2 and didn't notice improved loading speed. Later, I changed it with higher class one, same 8GB, with same manufacturer, Sandisk. Higher class one has name "Ultra" on it. Now with changed SD, loading became WAY faster. "Wow" I realized the higher speed of CPU of HD2.
My 2 pennies.
NEVER EVER buy unbranded memory cards!
Keep an eye on Sandisk cards only and even prefer them to Transcend and Kingston.

[Q] About SD Card

Hello
I got my Legend about 2 months ago, and I have a big problem with storage space...
What is the biggest sized SD card the Legend can use?
What is the type of SD card (micro, mini, etc...)
What is SD card class?
Thank you very much
microSD compliant with SD2.0 Standard (aka microSDHC)
The biggest size available currently is 32GB.
I don't know if even more is possible with microSDHC or if bigger cards will only be possible with SD3.0 (aka SDXC) but that question is not relevant as you can't buy any greater then 32GB yet.
The Class of the SDCard is a measurement for guaranteed minimum speed in random read/write.
The Class does not provide any information about real-world speed or max speed.
For your mobile phone the class is a pretty useless criterion as you don't need any guaranteed minimum speeds but good overall speeds ESPECIALLY sequential.
The guaranteed minimum speed is important for HD Video Cameras for example where you write data all the time at a given speed (resolution).
thanks.
but I DO need class with high speed because I want to use Data2Ext...
Don't pick uSD card based on class !! class tels you MB/s for sequential write only... you need a card that is overall fast, I had 16GB class 10 Kingston and data2ext was just horrible!
Now I'm with class 4 Sandisk mobile ultra and it is in fact faster in every test I ran...
So read reviews before you buy
ye but that is exactly why im asking...
well then, I recommend sandisk mobile ultra as I have it and it is OK, there are probably faster cards...just see the small files read / write speeds in reviews those are of greatest importance
i purchased a kingston 8GB class 4 which crapped out. android kept reported sdcard unexpectedly removed. tried all sorts (formatting in windows, android, quick, long, etc).
RMA replacement did exactly the same, so i'm guessing kingston class 4's are best avoided.
If I recall correctly I have a 16GB microSDHC Class 4 card. After applying data2ext with this card, my Quadrant scores hit around 1500, which is crazy.
This is where I found my card: http://www.amazon.co.uk/SanDisk-16G...P06K/ref=sr_1_1?ie=UTF8&qid=1298984123&sr=8-1
I personally recommend this card.
witch is better class 4 or class 6?

I've got a Sandisk Ultra Mobile 16gb SDHC which works fine in the Legend. Make sure you format it with the phone to stop it being dismounted, well known issue and the fix

[Q] Note sdcard read speed.

Hi,
I am eyeing for the sandisk mobile ultra 32gb class 6. It claims to have 30mb/s read speed which is really impressive.
But does galaxy note sdcard reader will be able to handle 30mb/s read speed? Because for what I know most card reader tops at 20mb/s which is why most cards even those class10 ones has read speeds of less than 20mb/s.
Please correct me if I am wrong.
Thanks.
I don't think Note can handle 30 mb/s .. someone with more insight on the hardware of the card reader on Note might be able to help you
I have 32GB 10 class I can help but tell me pliz how to chech the speed read write?

That's the 'realism' that I had in my mind. If I have a full 32gb card, and wanted to transfer my pictures and videos, which is what mostly the card will be used up for, how is the transfer speed will be? If I am able to use the full 30mb/s read speed on sandisk mobile ultra card, that can greatly reduce the amount of time to move 32gb of data off the sdcard.
For sdcard application usage within the phone itself, the only thing that I can think of that will use alot of bandwidth on the card is recording full hd video, which a class 6 card is more than enough to handle the write speed. If for read speed, a mere class 2 cards can do 8mb/s read speed which is fast enough to watch your regular hd video, listen to your mp3 etc.
You just can just connect the phone to pc as storage mass and the program will detect the drive. You can start the test using the software.
What is your microsd brand?
k heres my 2 cents, my family has 5 galaxy notes. Basically I tried many brands ranging class 4, 6 and 10. First off the class 4 32g are like 40% or so slower than the class 10's. The 2 class 10's I have are all different brand both 32g and I can tell you they don't really make a lot of diff in terms of speed its less than 0.5mb per sec diff (the slower class 10 is same brand as the Note and the other one starts with Lex???). Then you have the class 6 64g which runs up to around 10% or so slower than the class 10. At the end of the day what you find is class 6 and 10 are both fast but the class 4 are dam slow. On my machine I'm using the 64g card. Speed was determined and optimized by SD booster and SD tools.
Thanks for info, that's alot of GNotes you got there.. your family must like BIG SCREENS.
Anyway, my actual question was, is the GNote be able to handle 30mb/s transfer for the sandisk mobile ultra versions or atleast what is the highest read speed for GNote card reader.
There is one benchmark that I came across somewhere that proves that the card does actually deliever that transfer speed albeit using usb 3.0 port. It takes atleast a regular usb 2.0 reader on a usb 3.0port to achieve it. A usb 2.0 reader on usb 2.0 port barely makes the 20mb/s mark on the same card. So the usb 3.0 port is quite crucial even though a usb 2.0 reader is being used on it.
So yah, the ideal situation is someone actually has the sandisk ultra mobile card + GNote and is willing to give spare time to benchmark it for us and post it here.
