I don't think there is much tuning that can be done, other than |
11 |
putting them in a RAID0 array. SCSI already does DMA, so as long as |
12 |
they are attached to the fastest controller that the drives support, |
13 |
you are probably maxed out on throughput. |

BTW, 24MB/s on a 7200rpm 200G drive on an IDE channel seems very, very |
16 |
low. That number should be more like 65MB/s. Unless this is actually |
17 |
in a USB enclosure... |
