Late last year, Western Digital
decided to make the leap to the land of perpendicular
magnetic recording with its 160GB Scorpio
, and now the firm is stepping it up to a full quarter terabyte with its latest rendition. The 2.5-inch SATA drive fits nicely within the confines of most lappies, sports 8MB of cache, a 12-millisecond access time, spins at 5400RPM, and touts the company's WhisperDrive technology so you'll barely know its there. Additionally, the ShockGuard and SecurePark systems tag team to keep your data safe during turmoil, and the IntelliSeek system reportedly "calculates the optimum seek speed of the read / write head actuator to help reduce noise and power consumption." So if you're looking to up the storage capacity of your mobile machine, you can snag WD's latest right now for a penny under $200.
