Welcome to the Community Forums.
Some: HDD / SATA 6.0Gb/s, 2.5" wide, 7mm high
Some: M.2 SSD / PCIe 3.0 x 4
Best to check on your system on too as there was reports of missing SATA connectors (Type 80YY - Model CTO1WW) as it has different board. Discussion here.
Hope this help answer your query.
Update us how it goes for your machine.
