ASUSTOR DRIVESTOR 2 PRO AS3302T

Superb all–round performance at an unbeatable price

ALL THESE SYSTEMS provide reliable storage for Time Machine backups, and could replace a Time Capsule and provide shared storage for photos and documents. They differ in the other services available, expandability, and cost. As an appliance, WD My Cloud is ideal and inexpensive, but won’t do much more than those basics.

The four conventional NAS systems offer many different services and expansion potential. Their manufacturers also offer related models: QNAP’s four–bay TS–453D compares with the Synology tested, and Asustor offers its AS3304T. They’re similar in that each is a Linux computer with a file system more complex than your Mac’s, controlled through a browser. If you’re uncomfortable with that, or need macOS–specific services such as Content Caching, making your own NAS using a Mac is fine, if expensive.
