Hi guys,

I had a pretty obscurely branded usb flash drive (TX Think Xtra 16GB). I recently had to buy a new one (Kingston DataTraveler G3 16 GB) because the plug became wobbling and faulty (if you moved it even slightly it would loose the connection).

I used the old drive to run a live version of backtrack linux. So I installed it on the new Kingston too.

The issue is that linux runs tremendously slowly on the new drive. So I googled a bit and found many people complaining about DataTraveler G3 being slow.

So I decided to do some speed tests:

  1. HD Speed:
  2.  
  3. ->TX Think Xtra (16 GB):
  4.  
  5. ->Burst rate:
  6.  
  7. ->Read: 18.5 MB/s
  8. ->Write: 1.4 MB/s
  9. ->Write+Read: 1.3 MB/s
  10. ->Write+Read+Verify: 1.3 MB/s
  11.  
  12. ->Average:
  13.  
  14. ->Read: 18.4 MB/s
  15. ->Write: 4.2 MB/s
  16. ->Write+Read: 3.0 MB/s
  17. ->Write+Read+Verify: 3.0 MB/s
  18.  
  19. ->Kingston DataTraveler G3 (16 GB):
  20.  
  21. ->Burst rate:
  22.  
  23. ->Read: 24.2 MB/s
  24. ->Write: 17.8 MB/s
  25. ->Write+Read: 10.2 MB/s
  26. ->Write+Read+Verify: 10.2 MB/s
  27.  
  28. ->Average:
  29.  
  30. ->Read: 20.8 MB/s
  31. ->Write: 5.6 MB/s (but keeps oscillating like sin)
  32. ->Write+Read: 4.4 MB/s (but keeps oscillating)
  33. ->Write+Read+Verify: 4.4 MB/s

  46. ->4k QD32 Read: 0.0 MB/s
  47. ->4k QD32 Write: 0.0 MB/s

  50. ->Kingston DataTraveler G3 (16 GB):
  51.  
  52. ->Sequential Read: 22.37 MB/s
  53. ->Sequential Write: 6.667 MB/s
  54. ->512k block Read: 23.13 MB/s
  55. ->512k block Write: 0.951 MB/s
  56. ->4k block Read: 4.465 MB/s
  57. ->4k block Write: 0.048 MB/s
  58. ->4k QD32 Read: 0.0 MB/s
  59. ->4k QD32 Write: 0.0 MB/s

From this data it seems that the Kingston drive is faster than my previous one. Though linux ran flawlessly on it.

The only thing I could think about is that TX Think Xtra was much more stable on average reads and writes, whereas Kingston kept oscillating between high and low values (producing a sinusoid curve on the data plot) keeping a stable average though.

Any ideas about why the faster drive is actually slower than the slower drive?

Thanks in advance

try formatting the drive with
low level format

May be next paramaters is more important for boot/system flash drives
->512k block Write: 1.868 MB/s - 2x faster
->4k block Read: 6.600 MB/s - 1,5x faster
