Check out these two new hard drives: a suprisingly affordable 2TB desktop drive and a super-fast 7200RPM, 500GB notebook drive.
Hard drives are never a hard sell, thanks to the fact that too much space is never enough. But these two drives are going to be spectacularly hot sellers.
Western Digital has announced the industry's first 2TB 3.5" drive, using four platters that each hold 500GB. The drives also have a huge 32MB cache for repeat retrieval of cached data at raw SATA speed -- up to 300MB/s.
Video libraries seem to be the driver for sales of massive hard drives, according to an analyst quoted in Western Digital's press release. "While some in the industry wondered if the end consumer would buy a 1 TB drive, already some 10 percent of 3.5-inch hard drive sales are at the 1 TB level or higher, serving demand from video applications and expanding consumer media libraries," said Mark Geenen, President of Trend Focus. "The 2 TB hard drives will continue to satisfy end user's insatiable desire to store more data on ever larger hard drives."
Western Digital claims the 2TB "Caviar Green" drives also use less power than comparable desktop drives.
The drive, model number WD20EADS has a recommended retail price of $469, however on the day this article was written, online stores already had it listed as cheaply as $374.99.
And now for the ultimate notebook driveā¦
Now this is a first: the highest capacity notebook drive on the market is also the industry's fastest. Typically, hard drive makers make notebook upgraders choose between a super-fast drive with a lower capacity, or the maximum capacity running at a slower 5400RPM speed.
The new wonder drive we're talking about is the Seagate 500GB 7200RPM 2.5" notebook drive. There are two models:
Seagate 500GB 7200rpm 2.5" Mobile Serial ATA HDD w. 16MB Cache (ST9500420AS) Momentus 7200.4
Seagate 500GB 7200rpm 2.5" Mobile Serial ATA HDD w. 16MB Cache (ST9500420ASG) Momentus 7200.4, with G-Protection
The drives are surprisingly cheap -- the basic version can be found as cheaply as $200.40 (at BetterIT Australia) or $209.30 (also at BetterIT). Stock is listed as being due on the 1st Feb.
Seagate claims that despite their huge capacity, these are the lowest power 7200RPM drives yet to be sold, drawing only "slightly more power" than a 5400RPM drive.
The "G-Protection" version includes a motion sensor on the drive's printed circuit board that goes a step beyond traditional motion protection: it can senes falls greater than eight inches and will unload the drive actuator before impact.
Notebook drives haven't traditionally been big sellers at retail because they're more difficult to install than desktop drives. However, the advent of notebooks with easily accessible hard drive slots, as well as ultra-cheap external drive cases have made them popular upgrades.
