HP ThinClient T520 "Replace M2 Disk"

HP ThinClient T520 Replace M2 Disk Pay attention to the physical size of the m2 disk you will buy, I used KINGSPEC M2 2280/2242. I installed windows 10 but usage is very slow, it cannot be used as a pc. How to distinguish the differences between M.2 cards M2 - 2280 Series M2 - 2260 Series M2 - 2242 Series #HPThinClientT520ReplaceM2Disk #ThinClientReplaceDisk,
