[Cialug] Virtual Box and NAS

[Dave Hala Jr]

I'm not an expert on this, I'm trying to figure it out. It would appear
that the bottleneck is between the hard drives and the Nic, correct?
I'm assuming that you could come close to saturating a decent 1GB nic
with a hardware raid array consisting of a bunch u320 scsi drives, but
not even come close with Sata drives.
