Serial ATA
hard drives have been on the market right at a year now. Pretty much every
motherboard produced today has a built in SATA controller. I don't know if SATA
hard drives will ever outnumber ATA hard drives, but when it comes time to
upgrade, you should definitely go SATA. The advantages are obvious, it's all
about speed! Today we take a look at Seagate's newest Serial ATA150 hard
drive, the Barracuda 7200.7.
Specifications
The 7200.7 comes
in 4 sizes; 80, 120, 160, and 200gb. Our particular drive is the
ST3160023AS, 160gb drive.
