For this
test a single 8.5GB file is copied from an OCZ Vertex 2 SSD system disk to the
test disk (write to), from the test disk to the OCZ Vertex 2 SSD (read from),
and from the test disk to itself (read and write to self). While this test is
heavily influenced by the SATA controller and by the number of files being
transferred, it provides a good indication of the sustained transfer rates
capable from the hard drive being tested. Higher transfer speeds are best.

A simple
copying test in Windows Explorer illustrates the basic advantages this 2TB
Seagate Barracuda XT drive brings to the table.
2 Terabytes of Sweet Sweet
Drive Space
Hard drive capacity is always on the up and up, but the
standards which enable the PC to access those Terabytes of data, such as IDE and
SATA, change much less frequently. With the Barracuda XT Seagate
inaugurated the era of SATA III storage devices.
What's notable about Seagate's desktop 2TB Barracuda XT hard drive is that it was the
companies first 3.5" hard drive to support SATA-IO's Serial ATA 6Gb/s interface. The Barracuda XT is
built around a four platter 7200RPM spindle, with ramp loading for the heads and
64MB of onboard cache.
Architecturally the Barracuda XT is quite similar to
the Barracuda 7200.12, so evidently the bandwidth advances are coming by
way of the XT's enlarged cache and shiny new SATA 6Gb/s
hardware controller, rather than changes to its perpendicular magnetic
recording technology.
As we saw in the benchmarks the 2TB Barracuda XT drive
performed well compared to HDDs of similar capacity. On the price per GB front,
the 2TB Barracuda will run $0.125/GB. While SSDs are markedly faster, at a
cost of ~$1.58/GB (120GB) they are hardly large enough, nor cost
effective enough for the average home user.
Hard drives are the fundamental building blocks of every
computer system so it's good to know that Seagate is confident in its
Barracuda XT series; each drive is backed by 5 year warranty!
That's commitment. Whatever type of PC you're building, the 2TB Seagate
Barracuda XT is a worthwhile hard drive to consider.
