Samsung is joining the ranks of those manufacturers who are offering behemoth-sized 320GB hard drives for laptops. The M6 HM320JI is now the highest capacity 2.5” drive that Samsung offers, and at 5400RPM will probably fit in well with other offerings. The drive uses a SATA interface and boasts low output noise. Drives of this form factor and capacity have become increasingly popular not only for putting more storage into laptops, but for putting mass amounts of storage into slim servers such as 1U rack chassis or blade servers, where space is limited.

In recent days, Toshiba and Western Digital announced 320GB 2.5” drives as well. Mass storage on a laptop is now easier than ever, provided you want to spend the premium.
