Data storage doesn't tend to elicit wows or water-cooler conversations, but that's about to change: The Deskstar 7K1000 from Hitachi Global Storage Technologies -- the first hard drive to hold 1TB -- is here, and it apparently lives up to the hype.
Based on the PC World's evaluation, this huge drive is a keeper, scoring near the top on performance tests, but be prepared to pay a premium for this drive's high performance and high capacity.
One terabyte has long been considered a watermark capacity for hard drives, and rightly so: With that much room for storage, it's possible to pack 330,000 high-resolution digital photos (at 3MB a pop) or about 150 high-definition movies (encoded at 9MB/sec. using MPEG-4) onto a single drive.
Previously, if you wanted to achieve such colossal capacity, you'd have to harness multiple 200GB drives together with disk spanning, or pair two 500GB drives configured using either disk spanning or striping (RAID 0).
