Synology DiskStation DS223j 2-Bay NAS Review!

Synology DiskStation DS223j Performance


Synology DiskStation DS223j Performance

We tested three NAS systems, with these settings:

WD MyCloud EX4100

  • 4 x 6TB WD Red drives
  • RAID 1 with EXT4 file system

Synology DS223j

Synology DS214+

  • 2 x 4TB WD Red drives
  • RAID 1 with EXT4 file system

We then compared their read and write performance to a 1TB SDD, using a Gigabit LAN connection, and these two file sets:

  • Large File : Movie with a 9.3 GB file size
  • Small Files : 2193 photos with a 9.48 GB file size

Large File Read Speed

When it comes to transferring very large files like a movie, the Synology DS223j did very well, offering an average read speed of just over 100 MB/s!

Even the much older DS214+ model did very well, almost delivering 100 MB/s of throughput, and beating out 4-bay MyCloud EX4100 by 23%!

Large File Write Speed

However, when it comes to writing files to the NAS, the number of bays, and the drive speeds are what counts.

The 4-bay MyCloud EX4100 is far ahead, because it’s able to write to two drives at the same time (in RAID 1).

The faster 4TB Synology Plus drives used in the DS223j allowed it to pull ahead of the DS214+ by 16%.

Small Files Read Speed

This is quite a surprising result. For some reason, the Synology DS214+ did very well in this test, beating even the 4-bay MyCloud EX4100 by almost 30%!

And the Synology DS223j, which is much faster in every way, delivered a much lower speed of just under 48 MB/s.

Small Files Write Speed

That’s completely flipped when it came to write speed – copying small files to the NAS systems.

Again, the 4-bay MyCloud EX4100 has the advantage here, because it can write to two drives at the same time.

But the Synology DS223j did very well here, coming within 23% of the MyCloud EX4100. This is likely due to its faster 4TB Synology Plus drives.
