Key Specs
- Storage Drive Type: HDD (Traditional, mechanical hard disk drives are the most common type of storage because they're relatively inexpensive and offer huge capacities. However, they also generate both noise and heat. Solid state drives, also known as SSDs, are many times faster than hard disk drives and have no moving parts to wear out, but typically offer less capacity for the same price.)
- Rotational Speed: 5400 revolutions per minute (The rate at which the hard drive spins its platters. The higher the rotational speed, the faster the drive can read and write data.)
- Interface(s): SATA (Refers to the types of connections that devices use to interact and communicate with each other.)

Great Drive for a Home NAS
The Red series by Western Digital has been fantastic in my Media Server. I have 8 2 TB drives in it, and I have been running ZFS in a RAIDZ-2 configuration without a hitch for some months. Several of the drives have been in the server for over a year, and not a single error has occurred. Since they support TLER, these drives are great for RAID arrays (both software and hardware).

What I was looking for
I have a 2 bay NAS which I use for a backup of pictures. I wanted a drive big enough so I wouldn't have to worry about space for a long time. So far these drive have preformed great.

Using for Home NAS
I purchased 3 of these drives for use in a home NAS (DROBO5N). BBY had them on sale and it was a great price. The drives have been awesome and no problems. It was so easy to set them up. I also did some research and these WD Red drives got great reviews in the tech blogs as very reliable for NAS use.
