Synology DiskStation DS418j Review

Rating: 8.0.

Synology's J series of DiskStation NAS are aimed at the value end of the market. The latest 4-bay addition to the range is the DS418j, which takes over from the DS416j and is marketed as an entry-level 4-bay NAS for home data backup and multimedia streaming.

The Synology DiskStation DS418j is a replacement for the DS416j featuring a faster processor, a dual core Realtek RTD1293 processor clocked at 1.4GHz (the 416j used a dual core 1.3GHz Marvell processor) with more up to date memory than its predecessor and more of it. The CPU has a built-in hardware encryption engine.

The DS418j uses 1GB of DDR4 memory, an upgrade from the 512MB of DDR3 that its predecessor used. The memory is soldered onto the motherboard so you cannot upgrade it.

Synology quote Sequential throughput figures for the DS418j at 112.94MB/s for reads and 108.88MB/s for writes with the four disks built in a RAID 5 array.

For a 4-bay NAS DiskStation DS418j is very compact measuring just 230 x 168 x 184mm and it comes with just a single Gigabit Ethernet port and a pair of USB 3.0 ports built into the rear panel.


  • Dual core 1.4GHZ CPU.
  • Hardware encryption engine.
  • 1GB DDR4.
  • Single Gigabit Ethernet Port.
  • 2 x USB 3.0 ports.
  • Dual 80mm cooling fans.
