I should add that this was the 1st version of the ReadyNAS (NV4?), just
after it was purchased by Netgear.

Good to know.

For rules of thumb:

Gigabit ethernet is ~ 60 MB/s.  I've measured up to 100 MB/s on a high end
system.  I've seen a Windows 7 system do NFS at 50 MB/s, but 40 MB/s is
more typical.

A hard drive is usually ~ 60 MB/s after you saturate the cache ram.

USB 2.0 is ~ 30 MB/s.
