Hitachi Ultrastar and Seagate Barracuda LP 2TB drives

In my previous post I talked about Western Digital RE4-GP 2TB drive problems.

In this post I present my test results for 2TB drives from Seagate and Hitachi.

The test setup is the same as for the RE4-GP testing, except that I only tested 4 drives from each manufacturer.

Unlike the enterprise class WD RE4-GP and Hitachi Ultrastar A7K2000 drives, the Seagate Barracuda LP drive is a desktop drive.

The equivalent should have been a Seagate Constellation ES drive, but as far as I know the 2TB drives are not yet available.

Western Digital RE4-GP 2TB Drive Problems

In my previous two posts I described my research into the power saving features of various enterprise class RAID controllers.

In this post I detail the results of my testing of the Western Digital RE4-GP enterprise class “green” drives when used with hardware RAID controllers from Adaptec, Areca, and LSI.

To summarize, the RE4-GP drive fails with a variety of problems, Adaptec, Areca, and LSI acknowledge the problem and lay blame on WD, yet WD insists there are no known problems with the RE4-GP drives.
