I
always look forward to receiving new hardware. This time I was
especially stoked, because it's Seagate's new flagship drives that
include their new technology, Native Command Queing (NCQ). Yes I
did say "their new technology", because Seagate actually teamed up with
Intel to develop NCQ. We'll talk about NCQ a little later on,
right now let's check out these new drives.
