Single Client Performance Summary


You will almost immediately notice two QNAP TS-653 Pro results in our charts today. The first is a five-drive, RAID 5 array with a SuperSSpeed S301 120GB SLC SSD installed as a cache drive. The second configuration is with six drives, also in RAID 5.


The first thing we notice in the single client tests is the SSD cache performance in relation to the non-cached performance. For a majority of these tests, the cache actually slows the TS-653 Pro down, but only by a very small and unnoticeable margin. The QNAP 4.1 software allows users to set different perimeters for the cache SSD; we ignored sequential data, and just accelerated random data, which is the default option. In the single client tests where random data is present, the cache option increased performance as expected.
