Hello
I have installed five of these in my Synology DS1522+. They run smoothly and quietly, even though they are not on the Synology compatibility list.

I've had two of them in a 720+ for about two months. Running well so far

I have five Toshiba MG10 22TB in a DS1522+, they are recognised, but unfortunately only as 20TB HDs!

I have seen a lot of NAS only supporting up to 18TB, I would check on their website.
