Synology NAS and SSD Cache

Saturday, April 9th, 2016

I’ve been recently experimenting with SSDs (solid state disks), to accelerate my spinning rust in my Synology NAS.

Recently in DSM, a new SSD cache option is available, which allows you to create a read or write cache with 1 or 2 SSD devices respectively.

Here are some results, which I’ve graphed

In my very quick and crude tests, I could see an improvement in Writing to the NAS, which doubles in performance. Read speed is very similar, and the cache was “warmed-up” before testing.

And here’s a video of the new Synology SSD Cache Read Hit Rate graphic, which looks a little graphic equalizer, from the 70-80s, so I’ve dropped a music track in the background! I thought it only right to over-flange (distort!) the track, so you may want to turn down your volume!
