Western Digital s Caviar Green arrived earlier this year, thefirst drive to hit the coveted 2 TB capacity point. The unit wasrecently re-validated and is now available under the RAID Editionbrand (RE4) for business applications. Samsung sent us its 1 TBversion of the Spinpoint F2 EcoGreen, and Seagate provided thelow-power Barracuda LP, which now also hits 2 TB capacities andlooks to outperform other green drives while still emphasizingefficiency. Lastly, we also included Hitachi s Deskstar E7K1000,which isn t marketed as a green drive per se. Instead designed for24/7 operation, Hitachi s unit competes with WD s RE4 drive. Shorter Warranties Although WD s new RE4 drives are branded and labeled as enterprisestorage, the manufacturer only provides a three-year warranty, aswith its other desktop hard drives. But WD isn t alone. Seagate,which had offered five-year warranty for all retail products,quietly went back to three-year coverage several months ago.Samsung matches this warranty with its Spinpoint F2 EcoGreen. The one exception is Hitachi s Deskstar E7K1000 and its beefierfive-year warranty. We understand that competition in the hard drive market is terriblyfierce, but we also believe that long warranties represent the proper way for vendors to show they have confidence in what theysell. 5,900 RPM by Seagate Most drive makers target power savings by releasing new drivesbased on lower spindle speeds. WD and Samsung, for instance,re-introduced 5,400 RPM speeds on their green drives. Hitachi hasbeen reluctant to jump on the green bandwagon, with the exceptionof its 7,200 RPM Deskstar P7K500. This drive offers standout speed while keeping power consumptionrelatively low due to a single-platter layout. Seagate recently introduced its own spin on how a low-power desktopdrive should look. The Barracuda LP does rotate platters at reducedspeed, but Seagate decided to have the drives run at an unusual5,900 RPM, which is supposed to deliver the best combination ofhigh performance, high capacity, and low power consumption. We re about to find the out if Seagate s claims hold up underheavy testing.
