I have two Netgear NAS systems and they were populated with 2TB WD "Green" drives which performed well enough. Once I needed to expand the required space I decided to try the 4TB "Red" drives (the NAS systems can't handle the 6Tb ones :( ) and it was a good choice.

This is very much a middle-of-the road type product which hopes to bring mass storage to a desktop environment for those...

Mechanical hard disk drives have been around for decades now but it wasn't until the introduction of the first NAS (network attached storage) and digital NVR (network video recorder) models that the need for different models was even considered by manufacturers.

WD's Red 4TB HDD expands on the company's current offering with 33% more raw storage capacity than previously available in the same 3.5" form factor with a 6Gb/s SATA interface. The WD Red line also features 1TB, 2TB, and 3TB models, but now consumers and small businesses with one- to five-bay NAS...

At 4TB; this is now the largest hard drive available from WD that is tuned for NAS applications; Performs better than the Seagate NAS 4TB and the WD Red 3TB in single-drive benchmarks; Ranks very well in a multi-drive RAID5 setting in our Synology NAS environment
