Western Digital cracks the 2TB barrier

Western Digital has announced its latest drive, a 2 Terabyte Caviar Green hard drive with 32 MB of cache and a seek time of 8.9ms. It runs between 7200 or 5400 RPM depending on load, which saves power.

Due to advances in Perpendicular Magnetic Recording (PMR), it is able to achieve this using a four platter design, with 500 GB per platter. Having fewer platters reduces power consumption as well.

WDC's previous capacity champion was only 1TB, so this new flagship has been anticipated for use in DVRs and archival systems. The model number is WD20EADS, and is being shipped to distributors this week.

In addition to the 2TB model, Western Digital is also launching a 1.5TB model (WD15EADS) to accompany its revised 1TB model (WD10EADS). Both also feature 32MB of cache, which helps to increase access speed to commonly accessed data.

"While some in the industry wondered if the end consumer would buy a 1 TB drive, already some 10 percent of 3.5-inch hard drive sales are at the 1 TB level or higher, serving demand from video applications and expanding consumer media libraries," said Mark Geenen, President of Trend Focus.

WDC's primary competitor Seagate recently unveiled their Barracuda 7200.12 series of 3.5" desktop drives, featuring a 1TB 2 platter design. It is available with 32MB of cache as well.

Seagate is being particularly cautious these days, after firmware problems with the flagship Barracuda 7200.11 series of drives caused problems with RAID and Linux setups, and lowered prosumer confidence in the world's leading hard drive supplier.

Its Barracuda 7200.11 1.5TB drive (ST31500341AS) was previously the largest single hard drive available to consumers, and the only one to go above 1TB.

Seagate may very well release their own 2TB 7200.12, but they still haven't been able to supply the Momentus 7200.4 500GB laptop drives that they announced six months ago on July 10.

2 TB Drives

Lots of error correction going on with big drives, and, as mentioned before, lots of territory to be hosed in a failure. (and to wipe if you have to) Better to use something like Drobo and buy multiples of 500GB drives. Stock-up.

I could not imagine how long the OS would take to initialize a 6 terabyte volume on a drobo.

I think these drives would be good in a WHS or a decent NAS box.

These drives will be excellent in a WHS. I have plenty of open bays on my server and as soon as these show up on Newegg I will be sending out 'invitations'. That is assuming that these will price similarly per GB as the Seagate 1.5TB drives.
