Western Digital's Red line of hard drives are a combination of the lower power and low noise features of the Green series along with the 24/7 operation and longevity of the RE series. They are not the fastest drives, but are built for use in storage servers and other always-on systems that need large drive capacity - making them a perfect choice for NAS units, home servers, and RAID configurations.

We have an article where you can read about the differences between the Red and Green series in more depth here.

This is an excellent drive if you are looking for a cool and quiet operating drive along with higher capacity. This drive does run around 5400 RPM, where traditional drives run around 7200 RPM, so there will be a certain performance hit when accessing data on these drives. It's worth mentioning that these drives use 4KB sectors instead of 512B sectors, so if you intend to install Windows XP on your own with these drives, make sure to run the WD Align utility to allow you to properly install on this drive.

I like the Red series drives from Western Digital. I use two of these 2TB drives in a RAID1 at home with a simple NAS box that sits on top of my desk and another in my day to day system for storage. The Red series drives are quieter under use since they only spin at 5400RPM and have respectable performance as well. I would recommend Red drives for someone who just needs large amounts of space to store their media or projects.
