[ nb: You should save a lot of time copying to flash if you zip/tar/rar all your files together and copy them across as one big file. ]
These speeds do certainly sound way under the (what?) 20-40MB/s claimed write speeds for brand name flash sticks. usb2.0 shouldn't be imposing any bottleneck (max 60MB/s), assuming there's no other bottleneck that is.
Someone here posted their fairly unscientific results for write speeds for different brand name flash drives using both dsl and Windows a while back, saying the write speeds came in way under spec and that the '20x' (@ 150kB/s) etc designations appeared to be almost meaningless.
But then - you say the same drive got much faster transfer speeds when seen as an ide device. So then it is not the device that is the problem, suggesting you are not actually getting usb2.0 speeds at all.
Do we have any hardware engineers out there who could comment?
