That sounds about right!
You weren't expecting to get 100Mb/s were you??

ata100 is 100M*B*/s, not 100Mb/s. However, unless you are reading out
of the cache of the drive, you'll get a much lower speed (on the order

Actually, using a variety of Maxtor drives, I don't think I have ever
gotten anything better then 11.5 Megabytes/sec - and this was on boards
with ATA-100.
About a year ago I had several Tyan S2099's with a 40Gb Seagate, and was
doing drive duplications with dd and a FreeBSD boot CD. Again, 11
