Who makes a 160GB, 1.8-inch SATA disk spinning at 5400RPM? Nobody, until today. Toshiba just announced the industry's largest-capacity / fastest 160GB MK1617GSG disk for ultra-portables and netbook-class machines. While others have hit the magical 160GB mark in an 8-mm thick form factor, this is the first 1.8-inch SATA to reach 5400RPM. Oh, and because you're about to ask: no, it's too chubby for an iPod classic (where that speed wouldn't likely be noticed) or ultra-thin laptop like the MacBook Air or Envy 133. Thanks for asking though.
