Just to clarify a couple of things, because some of the terminology used here is ambiguous. This doesn't cover everything by the way, just what's relevant to you:
- You have HDDs (Hard Disk Drives), which are generally metallic boxes about 10 x 7 mm. They connect to the SATA ports on your motherboard using a cable, with a separate cable to your PSU for power. Inside they have mechanical spinning platters and moving heads.
- Then there are SSDs (Solid State Drives). These use memory chips like your RAM instead of any mechanical moving parts, but there are lots of different types and the names can mix things up:
-- There are SSDs that are the same 10 x 7 mm as HDDs and connect in the same way.
-- There are SSDs that look a lot like RAM modules but with the connector on the short side. These are called M.2 drives, and connect directly into an M.2 slot on your motherboard, no cables involved.
-- These M.2 types come in two kinds according to how they work internally, SATA and NVMe.
The point being that on a website selling these parts, "SATA SSD" can refer to a
plastic 10 x 7 mm box that connects to the motherboard via a cable like a classic HDD or it could mean a
M.2. drive that plugs directly into the motherboard. You can use the first type but you can't use the second because your motherboard doesn't have an M.2 slot.
