I just read that the throughput of the MaxAttach 6000 (with an IDE 
RAID) is about 180 Mb/s, and that the throughput of Dell's PowerVault 
755N (with a SCSI RAID) is about 230 Mb/s.


Also, I heard that Dell's new PowerVault 755N based on Tualatins can 
reach 470 Mb/s.

Naively, I had thought so far that striping over a dozen of disks gives 
throughputs greater than 1 Gb/s.  Could you please comment on whether

- the above examples are poor performers, and typical NAS servers give 
a throughput greater than 1 Gb/s?,

- it would make any sense to connect more than one Gigabit line from 
the cluster switch to the file server?,

- which NAS servers you would recommend that give a throughput of 1 
Gb/s?, and

- how much those beasts would cost?
