We wrote about Western Digital's first 640GB mobile hard drive yesterday, but WD competitors are also prepping similar drives for the coming weeks or months. Samsung, for one, recently announced its 640GB Spinpoint M7 hard drive, which also uses a two-platter design to achieve that capacity.
The rest of the 2.5" Spinpoint M7's specs sound prety similar to the WD Scorpio Blue's, too: a 5,400-RPM spindle speed, an 8MB cache, and a 300MB/s Serial ATA interface with Native Command Queuing support. The two drives even have similar suggested retail prices of around $150. Samsung says initial shipments "will be available in Europe and the U.S. from mid September," while widespread availability will follow by the end of the month.
Meanwhile, Toshiba has introduced another similar offering. The Japanese firm's new 2.5" MKxx65GSX lineup includes a two-platter 640GB model with, again, the same spindle speed, cache size, and interface. Toshiba doesn't quote pricing, but it says that drive will "ship to distributors and PC manufacturers in the fourth quarter of 2009." (Thanks to DigiTimes for the tip.)
