Hitachi can't lay claim as the first manufacturer to develop a 2TB hard drive -- that distinction belongs to Western Digital -- but it is the first one to do so with a 7200RPM spindle speed, besting the spindle speeds found on 2TB drives from both WD and Seagate.
"The new Deskstar 7K2000 reflects our ongoing commitment to provide customer, channel partners, and OEMs with proven, reliable solutions for enabling desktop computers, gaming systems, workstations, and desktop RAID arrays," said Brendan Collins, vice president of marketing, Hitachi GST.
Hitachi's fourth generation Deskstar crams 2TB onto a five-platter design "with relaxed bit density" and perpendicular magnetic recording (PMR) technology. As would be expected in a modern, high performance drive, the 7K2000 boasts 32MB of cache and a 3Gb/s SATA interface.
Owning a laptop used to mean being condemned to a low performance hard drive, but that's no longer the case. This past year has seen a surge in both higher performing and higher capacity notebook drives, and as of today, Toshiba tosses its new 2.5-inch 400GB model in to the ring.
The 7200RPM MK4058GSX packs 400 gigs onto just two platters with "an improved read-write head and enhanced magnetic layter to boost areal density to 477Mbit/mm²". Further separating itself from Toshiba's previous flagship 320GB 2.5-inch drive, the new model purports to cut acoustic noise during data seek by 2dB, all the while consuming 20 percent less power than its predecessor.
Five other drives round out the new lineup, coming in 80GB, 120GB, 160GB, 250GB, and 320GB flavors, and all of them support an optional Free Fall Sensor function Toshiba says will detect a failing hard drive and park the head before impact. Look for mass production to kick in late this summer.
