Fujitsu announces speedy notebook hard drive
Japanese firm Fujitsu has announced a new series of notebook hard drives it says is the world's first to combine a 2.5" form factor, 7200RPM spindle speeds, and support for 300MB/s Serial ATA transfer speeds. These new MHW2 BJ-series hard drives also use perpendicular magnetic recording, which allows them to reach capacities of up to 160GB—right in line with the highest-capacity notebook offerings from competitors like Seagate and Hitachi.
The rest of the drives' specifications include (PDF) 8MB cache sizes, power consumption of 2.3W during reads and writes, and purportedly "best-in-class" noise output of 25dB when idle. By contrast, Seagate's Momentus 7200.2 hard drives—which also go up to 160GB—feature (PDF) cache sizes of up to 16MB and read/write power consumption of just 2.1W, although they only support 150MB/s Serial ATA transfer speeds. Fujitsu says the MHW2 BJ drives will hit stores in 80GB, 120GB, and 160GB capacities in May.
