A couple of points to clarify.

You can get SSDs in 2.5" form factor or M.2 form factor ... this is the physical standard. As stated by DaMysteryMan, one main benefit of M.2 is that it requires no cables. So an example of a typical 2.5" SATA SSD would be a Crucial MX300 2.5" SATA SSD (https://pcpartpicker.com/product/2VWrxr/crucial-mx300-525gb-25-solid-state-drive-ct525mx300ssd1).

Now for M.2 SSDs, there are two main/popular types/protocols:

1) M.2 SATA ... which uses the same SATA standard as a 2.5" SATA SSD and so has the same speed performance and the same SATA speed limits but in an M.2 physical form factor. An example would be the Crucial MX300 M.2-2280 SATA SSD (https://pcpartpicker.com/product/34Nypg/crucial-mx300-525gb-m2-2280-solid-state-drive-ct525mx300ssd4). SATA M.2 SSDs perform comparably to 2.5" SATA SSDs.

2) M.2 NVMe ... which uses the NVMe protocol which is even faster than SATA SSD. An example would be the Samsung 960 Evo M.2 NVMe (https://pcpartpicker.com/product/Ykbkcf/samsung-960-evo-500gb-m2-2280-solid-state-drive-mz-v6e500). Look for "NVMe" in the product name and specifications. NVMe M.2 SSDs are faster that SATA SSDs but also cost more.

So the question of which one is best for you would depend upon your build and what your'e trying to do with it and your budget?

Here's a good/short video which compares typical user experience (note that the M.2 SATA will perform comparably to 2.5" SATA): https://www.youtube.com/watch?v=S4zdft1HDbY

Hope this helps.

M.2 means less cable management, and just as fast as 2.5" an NVMe SSD could benefit with large file transfers.

Not all M.2 SSDs are NVME, so watch out for that.

m.2 is faster but more expensive. 2.5" are a little bit slower but a little cheaper. I would get a 250GB m.2 for about $120.

That is not true at all. M.2 and 2.5" is a form factor. It has absolutely nothing to do with speed or performance.

So just to clarify, an m.2 without NVMe is gonna be the same speed and such as a 2.5SSD, but has the benefit of no cables and popping right into the Mobo instead of taking up an internal bay?

Can you get a 2.5 with NVMe or are they generally all SATA?

NVMe drives are all either in M.2 or PCI-E.
