This was for an individual drive.

I didn't try this, I will do that. >=20 >> =46rom what you've written, the bottleneck could be the controller, = the > port multiplier, or the drive itself. 131 MB/s sounds about right > for a single drive, unless it is some super high performance drive > or you are reading from the drive's RAM rather than from the platters. > I can get 253 MB/s reading from a drive's RAM.
