Western Digital unveils 3TB internal HDD

by Darren Allan

Western Digital has announced that it is shipping what the company claims to be the world’s largest capacity SATA hard drive.

The two new drives in the WD Caviar Green eco-friendly range deliver 2.5TB and 3TB of storage respectively, using 750GB per platter areal density. They boast 64MB of cache.

Western Digital’s GreenPower Technology reduces power consumption and decreases noise levels, with the reduced power levels also bring lower operating temperatures and hence a more reliable performance overall.

Hard disks which are bigger than 2.19TB currently cause problems for PCs, so WD is bundling an Advanced Host Controller Interface (AHCI) compliant Host Bus Adapter, which will let the OS connect with these large capacity monsters.

Jim Morris, Executive VP and General Manager of WD’s Client Systems Storage Group, commented: “WD remains a leader of hard drive capacity and low power innovation. With our WD Caviar Green drives, we enable energy-conscious customers to build systems with the highest capacities that deliver the optimal balance of system performance, ensured reliability and energy conservation.”

The WD25EZRSDTL 2.5TB drive will retail at $189, and the WD30EZRSDTL 3TB disk will weigh in at $239, both coming with a three year warranty. The UK pricing hasn’t yet been announced.
