what manufacturer says about usb speeds?
that is the question
Well, "up to 56MB/s" which is pretty much full USB2 speed.
But writing it on the box doesn't mean the speed can actually be
reached.
Benchmarking on windows might be interesting, but I don't know how to
measure raw disk io on windows.
Format the disk, copy a large file to/from it, divide
its size by time spent, add the word "approximately" :-)
I'd rather not format a drive with my backups and other stuff on it :-)
If you want to test under windows then you could use hdbench from c't
magazine. I think it has a non-destructive mode. It's what they use to
do all their disk tests.
Thanks for the tip. Using h2benchw, I get 30.5MB/s - so no magic speed
increase on windows. The limiting factor is not the hd, using ata I get more
than 65MB/s.
According to [1] "The maximum rate currently (2006) attained with real devices
is about [...] 30 MB/s".
