The physical connector is called M.2. The dimensions of the “sticks” are given in a number such as 2280, meaning 22 mm wide and 80 mm long. There are different lengths available from 30 to 110 mm. M.2 has different “keys”, meaning there are several variants of electrical hookup. Depending on that, it can support SATA, PCIe, or both. NVMe is a protocol that usually runs via PCIe. So for a modern setup, one usually buys NVMe drives, meaning they are connected via PCIe either directly to the CPU or over the chipset. > For most > people, that is likely awesome.

There is also the other way around that: an adapter card for the M.2 slot that gives you SATA ports. > I have considered getting a server type mobo and CPU for my new build. The only reason I got a server board for my little 4-slot NAS is to get ECC support. (Plus you don’t get non-server Mini-ITX with more than four SATAs). But it runs the smallest i3 I could get. It’s a NAS, not a workstation. It serves files, nothing more. I don’t mind if updates take longer than on a Desktop, which is why I don’t see a point in speccing it out to the top CPU-wise. This only adds cost to acquisition and upkeep. I just did the profile switch to 23, and it rebuilt 685 packages in a little over six hours, plus 1½ hours for gcc beforehand. > As you point out, they are packed with features I could likely use. “Could likely”?

I don't know if that would even serve my purpose. Exactly. Those boards and CPUs are made to run servers that serve entire SMBs so that the employees can work on stuff at the same time. As a one-man entity, I don’t expect you’ll ever really need that raw power. If it’s just for SATA ports, you can get controller cards for those. > The biggest thing I need PCIe slots for, drive controllers.

ROFL Nice one. -- Grüße | Greetings | Salut | Qapla’ Please do not share anything from, with or about me on any social network.
