Advice on Voyager GTR 32 stick


gkaytaz

Recommended Posts

Hello everyone.

I just got a Corsair Flash Voyager GTR 32GB USB stick. There are a couple of questions I would like to ask you guys to benefit from your experience.

First a little background info:

I am using two computers (older one with Win XP Pro SP3 32-bit and a newer one with Win 7 Home Premium 64-bit). The stick I bought will be used solely to transfer experimental result files (both text and binary) between those. Number of files range from 2000 to 3000 per transfer and individual file sizes range from 4 to 10 MB (total data amount varies from 10 to 30 GBs).

Now the questions:

1) What is your recommendation for the format FAT32, exFAT or NTFS?

2) What would the best cluster size be?

3) Should I prefer to zip all 2000+ files and transfer as a whole or copy them individually?

Thanks for all your help.

Cheers.

ntfs is needed for large file sizes. why not just use a crossover network cable? or are the computers at different locations?

 

Thanks for the reply.

 

The files are not very big (4 to 10 megs each). They are just numerous.

 

You are correct. The computers are some 25 miles apart.

The drive will be Fat32 by default and with Fat32 you will have a file size limitation of about 3 Gig per file for speed sake I would suggest using 3 or 4 -3 zip files and transfer or cop the files on the flash drive in that way.

Here's the benchmark file of my Corsair Flash Voyager GTR 32GB as promised... All tests done using HDBench 200MB file, O/S Win 7 Home Prem 64-bit (stick was formatted with FAT32 on the Win XP Pro SP3 machine earlier today). Antivirus, firewall, other non-essential tray programs all shut down during the tests.

 

1) Connected to a USB 3.0 port (via the supplied USB cable):

Read - 30038

Write - 24812

Random Read - 30104

Random Write - 6855

 

2) Connected to a USB 3.0 port (direct connection):

Read - 30038

Write - 24812

Random Read - 30104

Random Write - 6862

 

3) Connected to a USB 2.0 port (via the supplied cable):

Read - 30108

Write - 24812

Random Read - 30104

Random Write - 6848

 

4) Connected to a USB 2.0 port (direct connection):

Read - 30104

Write - 24860

Random Read - 30104

Random Write - 6840

 

5) Connected to a front USB 2.0 port:

Read - 30108

Write - 24812

Random Read - 30108

Random Write - 6869

 

These are pretty much identical. I guess I have hit a limit set by the motherboard or the O/S. Then again 30 MB/s and 24.8 MB/s are quite impressive. I will try the same config on the Win XP machine on Monday and post the results here.

 

Just for kicks here's the HDBench benchmark identical to test 5) except that filesize has been changed to 100 MB:

6) Connected to a front USB 2.0 port:

Read - 29959

Write - 23352

Random Read - 30099

Random Write - 3626

 

These numbers prompted me to try a larger file. Same test with a 500 meg file:

7) Connected to a front USB 2.0 port:

Read - 30108

Write - 25861

Random Read - 30108

Random Write - 5403

 

Last but not least some Atto benchmarks for test #7 (everything left at their default values):

Tr size - Write - Read

0.5 - 407 - 450

1.0 - 676 - 1365

2.0 - 1274 - 2730

4.0 - 1473 - 5461

8.0 - 6869 - 9372

16.0 - 11484 - 16384

32.0 - 18170 - 23860

64.0 - 24453 - 30840

128.0 - 24591 - 30840

256.0 - 26240 - 30840

512.0 - 26137 - 30854

1024.0 - 26577 - 30854

2048.0 - 26736 - 30854

4096.0 - 26604 - 30854

8192.0 - 26709 - 30854

 

Again I seem to have hit a limit. Perhaps the stick needs to have a different cluster size than the default one or the file system needs to be changed to exFAT or NTFS. I guess things will become clear after I finish tests with Win XP on Monday.

 

Would it make a difference if I formatted the stick with Win 7 (FAT32, default cluster size)?

What possible bottlenecks are there that limit the transfer speed?

 

That's it for now.

 

Wishing you all a great weekend... Cheers!

Easy, please... As you can see from my earlier post, my intention was never anything like that. It just so happened that an English word caused a filter to kick in and I made a simple remark about it. Sorry if I offended anyone :bigeyes:

Part II of the benchmarks. All tests done using HDBench 200MB file, O/S Win XP Pro SP3 32-bit (stick was formatted with FAT32 on this machine). Antivirus, firewall, other non-essential tray programs all shut down during the tests.

 

1) Connected to a USB 2.0 port (front panel):

Read - 33862

Write - 23700

Random Read - 33862

Random Write - 6559

 

2) Connected to a USB 2.0 port (back panel):

Read - 33862

Write - 21915

Random Read - 34042

Random Write - 6602

 

Next test was to repeat the previous ones with a 100 meg file:

3) Connected to a USB 2.0 port (back panel):

Read - 33761

Write - 19501

Random Read - 34121

Random Write - 3377

 

4) Connected to a USB 2.0 port (front panel):

Read - 33595

Write - 22362

Random Read - 29510

Random Write - 3353

 

ATTO benchmarks (all defaults):

Tr size - Write - Read

0.5 - 425 - 874

1.0 - 623 - 2403

2.0 - 1356 - 3891

4.0 - 1710 - 7858

8.0 - 10850 - 12800

16.0 - 16995 - 21277

32.0 - 22808 - 28555

64.0 - 26319 - 34492

128.0 - 26162 - 34538

256.0 - 26214 - 34402

512.0 - 26036 - 34503

1024.0 - 26525 - 34458

2048.0 - 26525 - 34370

4096.0 - 26525 - 34370

8192.0 - 26577 - 34195

 

These numbers made me think that the GTR reads a little faster in the machine it was formatted on. Does that make sense? Also Win 7 seems to have better writing benchmarks compared to XP (HDBench and ATTO disagree on this one). I am inclined to say that overall Win XP suits the stick a tad better...

 

I will repeat these tests next week and try to come up with some statistics.

The controller and the operating system you use can both have an impact on performance but it seems your drive is performing at or above spec so I do not see any problems..

 

I am very happy with it. Just wanted to share the data and perhaps find out ways to make the stick perform at its peak...

I do not remember the review site off the top of my head but there are several good reviews that discusses performance with our GTR drives just search for Corsair GTR drive and reviews I am sure you will find them. I will look for them when I have a chance but check on the Review Link on our main web site
