M.2 SSD requires expansion board
The QNAP TS-253D-4G ($369) is a two-bay NAS designed for business and home users who require a network attached storage device that brings high-speed connectivity and expandability. Powered by a robust 2GHz Intel Celeron J4125 quad-core processor, the TS-253D turned in solid scores in our file transfer performance tests and offers a nice selection of apps. That said, our Editors’ Choice winner for two-bay NAS devices, the Asustor AS6602T, is a bit faster and offers a more extensive app catalog for just $30 more.
Plenty of Ports
The TS-253D-4G uses the same basic chassis as the TS-251B-4G we reviewed in 2019, but this time around it sports a black and gray finish rather than a white and silver one. It’s a two-bay NAS that measures 6.6 by 4.1 by 8.9 inches (HWD) and can accommodate 2.5 and 3.5 inch drives. It supports single JBOD, RAID 0, and RAID 1, and supports a total capacity of 32TB using two 16TB drives. Larger storage capacities can be achieved by connecting the NAS to a QNAP SATA or USB expansion port.
