A closer look:
In today’s world where you get fancy packaging to go with the latest hardware, I was to be very surprised when Seagate sent the Barracuda XT in nothing more than a OEM clear plastic case, very low tech but none the less effective at protecting the drive, hopefully the consumer will feel all that extra savings…
The drive itself does not have much to commend physically. The drive looks like a standard 3.5 inch drive thicker than some but by no means a large drive.

A close up of the label on the disk. |
Hopefully the benchmarks show a more unique drive because Seagate really went all out trying to make this drive stand out…. just kidding.
Taking a closer look at the specs will hopefully reveal a bit more about this drive.

A couple of interesting facts here, first this is likely 2 platter drive and as we can see it has a high Areal Density (avg). an increase in areal density almost always is followed by an increase in performance as well as the ability to read data more quickly. The spindle speed has not increased so we do not see a noticeable increase in the energy draw of this drive.
