Techgage posted a look at Western Digital's Red (2TB) NAS hard drive

When Western Digital first unveiled its 2TB Caviar Green drive in 2009, those who were planning on building a home server or purchase a NAS felt that they were a no-brainer choice. After all, what's better than low-power and huge storage? Well, that was before we learned the caveats of using such drives in a NAS, or even with a RAID controller in a home server.

WD's long-overdue solution? NAS-specific models.

One of the biggest issues WD's Red drives remedy relates to error correction, a great feature for the desktop but one that could create a critical problem in a NAS or RAID configuration. Typical desktop drives are not designed to work with a RAID controller, resulting in both the OS and the RAID controller trying to handle errors. In the event that the OS prevents the RAID controller from doing its thing, a drive could disappear from the RAID, and could cause the controller to believe that the array needs to be rebuilt. Clearly, this is the sort of problem that could ruin your evening.
