A quick glance at the portable hard drive space shows why this drive is so special. There are other 2TB drives out there, WD announced a 2TB 2.5" drive two years ago, but with a drive height of 15mm, WD was going after the portable hard drive market, which had stagnated with the rest of the notebook hard drive market that stalled out at 1TB. The z-height makes the WD drive too tall though for notebooks, due to its use of a 4 platter design. The Samsung M9T accomplishes its massive storage by solving the density problem, utilizing three 667GB platters within its confines. While it's easy to forget that Samsung, now a Seagate company, is still cranking away at the hard drive business, they've certainly come back with a bang with the M9T.
The M9T is highlighted by its capacity and physical size, but there's plenty of other engineering inside. The drive is notably quiet thanks to its use of NoiseGuard and SilentSeek technologies; it reportedly maintains 25 decibels while idle and 27 decibels during performance. It comes equipped with both ATA Security Mode and ATA S.M.A.R.T. features to keep the drive protected from anyone but the intended user. The Spinpoint M9T also comes equipped with standard head load/unload technology to keep it protected from internal physical damage, which is a consideration with any HDD.
at 5400rpm it is a bit slow
