Flash survivor 32gb - Slow write performance

Recommended Posts

Hi,

 

I've got a Survivor 32 GB which seems to be suffering from poor performance, particularly write speed. I had previously formatted as NTFS but having read a few posts here, I formatted back to Fat32.

 

It didn't produce a massive bump in speed. I've now used the SDCardFormatter rather than Windows format to see if that improves things. I used HDBench before and after the SDCardFormat and got exactly the same performance figures.

 

HDBench ran with the 100Mb file produced the following results:-

All: - 5755

Read: - 17317

Write:-6717

Random Read: - 19133

Random Write: - 2873

 

I've had a look round the Corsair website to see if there are any performances figures quoted for this product, but can't seem to see anything. Are these figures really to be expected?

 

I've got a number of Corsair USB flash drives (4 & 16GB Voyager, 16GB Voyager GT) and this is significantly slower than any of the other drives. I would obviously expect this against the GT, but I didn’t think that there would be a massive difference between Survivor & Voyager performance.

 

Cheers,

Ram Guy,

 

Thanks for the quick response. I've submitted a RMA request as advised. Out of interest, what sort of numbers should I be seeing for this model?

 

I would have though pretty much the same as a voyager? As I assumed the internals would be the same just different packaging?

 

Thanks,

Hello

I'm writting to you from Romania. Here are some figures that I've obtained with my 16GB Survivor (8 consecutive tests):

(I formatted the drive both in command line and SDFormatter V2.0)

 

Read Write RRead RWrite

19964 6115 18587 2147

21122 6394 17155 2072

21165 6126 16704 1728

21302 6722 17038 2082

21209 6483 16623 2090

21209 6467 16704 2090

21481 6722 17126 2076

20906 6463 16384 2090

 

Here is the serial number on the USB plug of the Survivor stick:

G16C

FG2910232

 

Is this what can be considered a normal speed for this drive?

 

Thank you

Vlad

I forgot to check test with the factory format. I used the command prompt format (FAT32 /u /32K) and then ran HDBench 3.40 with 100MB.

I got(XPSP3);

Rd 22515

Wr 5586

RRd 23230

RWr 2023

I the tried the SD formatter(v2000) and it failed with something like 'illegal size error'.

I then formatted it with XP's Disk Managment(32K) and then I got;

Rd 28240

Wr 10065

RRd 28484

RWr 2751

I am consistantly getting 10xxx Write speeds now.

I have the same drive 32GB survivor and while I have pretty agreeable read speeds my write are consistantly very low.

 

What file format / formatting methods should a person consider as best practice for a flash drive of this size.

 

Currently I'm formatted NTFS

Windows reports average write speeds of under 3MB/sec - never above 3.

 

I used windows to format the drive.. If another method is preferrable please feel free to suggest something better.

 

Thanks

today I received my rma replacement for the Corsair 32gb Survivor and it is slower than I can imagine. Same problem as the first one i bought. When I tested it today on both my PC and MAC it was stating it was going to take over 3 hours to load 8 gigs of data. I tried using the format tool listed in these forms and it crashed my system.

 

When I run the system test from HDBENCH I get

 

Read - 0

Write - 0

RR - 242678

RW - 387965

 

Not worth the trouble. It took quite some time to get the replacement unit also. I guess I will have to pay for shipping again and wait some more.

In the mean time I purchased a 16gb from another brand and its plenty fast.

Big Difference when moving a small file and larger file appearently.

 

Thanks for the help..

If I can get similar speeds moving files I think it's working properly.

 

Thanks again,

Mal
