A potentially good deal right now is the Quantum Lightning 730S
(~699MB formatted, 4500RPM, 11ms avg. seek). The internal version is
selling for about $230 (APS Technologies), which translates into around
$0.32/MB. With a 1542CF controller, I get around 2MB/sec sustained
transfers (iozone results have been appended). Not great, but not bad,
either. For more info, see:
http://www.quantum.com/products/lightng.html
I've got no connections with Quantum, aside from being a customer.
The only downside is that the 730S has only a 2yr warranty. I
guess I'll find out what the reliability is like.
