To take advantage of the Barracuda XT's 6Gb/s SATA III interface, your
computer will need SATA III complaint ports, either via the motherboard chipset
or a hardware controller such as the Marvell 88SE9123. If this part of the chain
is absent, the drive is backwards compatible with SATA 3Gb/s and SATA 1.5Gb/s
It's considered good form to use 6Gb/s SATA III rated cables with SATA III
hard drives. The reason is that some cheap SATA cables bundled in with
motherboards may be fine at SATA II levels, but are subject to electrical
interference that hampers SATA III speeds due to lack of cable shielding, poor
quality materials, etc.
This isn't to say there are any differences in
terms of electrical connections between SATA III / SATA II / SATA cables, there
are not. Suffice to say, not all SATA cables are created equally, but at least
SATA 6Gb/s rated cables should be of sufficient tolerance.
The 3TB Barracuda XT is rated for an average latency of 4.16ms and
is compatible with SATA III, SATA II and SATA I interfaces.
Power is supplied by a SATA style power connector. The 3TB Barracuda XT drive
wasn't too loud by our standards, idling at 2.8 bels and generating 3.2 bels
when seeking. Average operational power consumption is a modest 9.23W.
Alrighty, let's power up this 3TB SATA III drive and test it!
