We've been around this stuff long enough to know that hard drives just keep getting bigger with time, but if you were eager to know exactly when a 1TB unit would be prepped and ready for your notebook, try 2010. According to those infamous "undisclosed sources," both Western Digital (which started shipping a 500-gigger today) and Fujitsu are looking to pump out 750GB 2.5-inch HDDs by mid-2009 and 1TB variants in 2010. Keep the faith, brethren.

WD has been shipping a 320GB laptop hard drive for months now, but its latest line of alternatives features a few niceties reserved for the Scorpio Black label. Available in 80/120/160/250/320GB sizes, the 2.5-inch drive boasts a 7200RPM spin speed, SATA interface and 16MB of cache. The units are destined for use in OEM systems as well as by end-users looking to upgrade their current rig, and beyond the specs listed above, you'll also find IntelliSeek, SecurePark, ShockGuard and WhisperDrive technologies alongside a built-in free-fall sensor. The whole lot is available now, with the 320GB edition topping out at $249.

No, SanDisk's latest offering in the ever-populating SSD realm is far from the largest, but just a tick after releasing a 1.8-inch edition, now the firm is unveiling a laptop (and external enclosure) friendly 2.5-inch flavor. The SanDisk SSD SATA 5000 2.5-inch is touted as a "drop-in replacement for the hard disk drive," and also boasts the durability that purportedly comes with being a fifth-generation product. Additionally, the NAND-based drive features a sustained read rate of 67-megabytes per second, reportedly enabling it to boot Windows Vista Enterprise on a lappie in "as little as 30 seconds." Of course, SanDisk didn't mind flaunting the low power consumption on this one either, as it boldly proclaims the 0.9-watts used during "active operation" as being nearly half as conservative as typical drives. While we're not exactly sure just how much these things will run the average consumer just yet, they are supposedly shipping to computer manufacturers now at around $350 a pop.
