On a slightly-related topic, any idea what sort of performance have you
been able to get out of the 2200S?  (The number of disks and what kind of
array(s) you have would be helpful to know.)

I'm mainly wondering about sequential performance, since random performance
is harder to gage.

e.g., with my Adaptec 5400S/HP NetRAID 4M, I can get about 92MB sequential
read performance with a 6 disk RAID-5, and up to 50MB/sec sequential write
performance on the same array.

With a RAID-1 array composed of the same disks, I can get 66MB/sec read
performance, and up to about 30MB/sec write performance.

(I'm using Seagate ST373307LC disks -- 73GB, 10K RPM.)

This is with -current from late February.
