The following graph shows the overall performance of the NAS on all tests we conducted using our custom made software.
Performance in RAID 1 is high, considering the hardware that the DS212j uses. On the contrary, file transfers through the USB 2.0 ports are sluggish, especially if the external disk is formatted using the NTFS file system.
Now let's check the performance of the DS212j against other NAS devices. Currently we have measurements of few NAS devices but after more reviews the following graphs will become much richer.
