The following graph shows the overall performance of the NAS on all tests we conducted using our custom-made software.
This small NAS performed pretty well thanks to its dual-core processor. The external USB 3.0 case we usually use for all NAS reviews wasn't compatible with the USB 3.0 controller of the DS213+, but we had a second case that was able to fully exploit the speed of the USB 3.0 ports on the NAS. The external disk with the EXT4 file system was, as you can see, much faster than the NTFS.
Now, let's check the performance of the DS213+ versus other NAS devices.
