Synology DiskStation DS120j single bay NAS Review – sub £100 NAS !

Rating: 8.0.

The latest addition to Synology’s popular j range of entry-level home use DiskStation NAS units is the single-bay DS120j, powered by a dual-core processor. For less than £100, is this a NAS worth buying?


The processor in the new DiskStation 120j is the same 64-bit dual-core Marvell Armada 3700 88F3720, clocked at 800MHz that powered its predecessor, the DiskStation DS119j. But while the processor might have stayed the same, the DS120J gets a memory upgrade with twice the amount, 512MB, compared to the 256MB of the DS119J of DDR3L. If you feel that you still need a bit more poke from the memory department, sadly you are out of luck as you can’t add to the system’s memory.

The DiskStation DS120j combines frugal power demands – 4.86W in HDD hibernation and just 9.81W when fully active, very slightly down from the DS119j – with low noise emissions when it’s hard at work.
