I have a 2940UW and as far as I can determine, under the best
conditions with NetBSD 1.5.x, it can't achieve even 20Mb/s in
benchmarks with (three different) scsi2wide drives that should be
able to approach 40Mb/s. Since the same machine runs a 7200 ata100
at 40Mb/s (even writes) with the same benchmarks, can I assume a
problem with NetBSD and the Adaptek firmware (even updated to the
latest version) or hardware?
