Western Digital announces 1TB 9.5mm thick notebook drive

The standard-sized 1TB 2.5-inch drive is now available for $139

California-based hard disk manufacturer Western Digital (WD) has announced through a press release today its first standard sized 1TB notebook hard drive.

The 9.5mm thick, 500GB per platter drive should fit snugly into most mainstream notebooks. The company has previously offered a 1TB notebook drive but in a thicker 12.5mm casing with 333GB per platter. By increasing the data density, WD has managed to reduce the number of platters from three to two and thus decrease the total thickness.

As part of the Scorpio Blue lineup, the HDD uses WD’s SecurePark technology for increased reliability, be shock tolerant up to 400Gs and is optimized with Advanced Format for a variety of Windows and Mac operating systems.

The 1TB drive is currently available in one model, the WD10JPVT. According to the spec sheet, the drive runs at 5400RPMs while the older, larger 1TB model (WD10TPVT) at only 5200RPMs, so expect performance speeds of the new drive to be slightly faster. For example, the new drive has a maximum data transfer rate of 150MB/sec between it and the host, while the slower model only at a maximum of 124MB/sec. The drives are otherwise identical in cache (8MB), SATA interface (3Gb/sec), average latency (5.50ms) and capacity.

WD isn’t the first company to announce a standard-sized 2.5-inch HDD, however, as Samsung revealed its own 9.5mm thick drive just this June.

The 9.5mm WD Scorpio Blue 1TB notebook drive is now shipping for $139 (97.98 Euros) and is covered by a three-year limited warranty.
