1GB Flash Voyager with slooooow writes

Recommended Posts

Bought this drive about 18 months ago and it's never been right. Always meant to do something about it, and now I've got some RAM to go back on RMA, might be the opportunity to kill two birds with one envelope...


Anyway, have two 1GB Voyagers. One of them has always been fine, the other has always written at dog slow speeds. Here are some tests, writing from hard disk to the two USB drives


626MB .ISO Image

drive 1 32 secs

drive 2 158 secs



469MB folder containing 167 large image files

drive 1 33 secs

drive 2 323 secs



635MB folder containing 613 mixed size image files:

drive 1 55 secs

drive 2 850 secs (yes, over 14 minutes!)


HDBench scores for drive 2 are read=18775, write=2512, random read=18775, random write=580.


As you can probably work out from those scores, it particularly struggles with smaller files - even tiny text files a few bytes long take a second or so to copy over.


Read performance is and always has been fine, but as you can see, it's normally better to go away and make a cup of tea when I'm copying something over to it. Have tried unconditional formats from the command line, repartitioning, switching from FAT32 to FAT, everything I can think of.


Is there anything else I can try?

Please try to format the drive from a command prompt with this syntax:

Format (X:) /FS:FAT32 /U (X=the drive letter assigned to the Flash Voyager)

Please try the HD-Bench software to test the performance.

The write should be about 2-6 MBps and read should be about 20 MBps.

If you still have problems we can get it or them replaced, please use the RMA request found in TSXpress or follow the link in my signature “I think I have a bad part!” and we will be happy to replace them or it!
