Analyzing the performance of a NAS hard drive is a little tricky, because we have to benchmark it into a different enviroment than the one they are intended to work. They are designed to be used in specific cases connected to a network, that fit from one to a large amount of hard disk drives.
The WD Red Pro HDDs are aimed on enterprise enviroments, into NAS units up to 16 drives. However, some people ask if is there any problem to use such a hard disk drive in a desktop computer (gaming or workstation). Theoretically, the only problem is its price, usually higher than the high-end desktop-aimed HDDs.
In our tests, the WD Red Pro 5 TB was consistenly faster than the WD Black 4 TB, which is a high-end desktop drive. So, if you can (and want to) pay a little higher, the WD Red Pro 5 TB is a very high performance drive, that can be used on a desktop PC.
