I seem to be good at giving too-late advice.
The coming thing in SSDs is NVMe. <https://en.wikipedia.org/wiki/NVM_Express>
These live directly on the PCI bus and thus get rid of the SATA bottleneck. But most current SSDs aren't significantly bottlenecked by SATA.
You need OS support (in Linux for 5 years but improved more recently) and hardware support (prehaps only firmware for booting from NVMe). I bet that your motherboard, chipset, and CPU chip support NVMe.
NVMe SSDs cost more than SSDs with SATA, mSATA, and m.2 connectors.
I don't think that any of my machines supports NVMe.
Some NVMe come as m.2 modules. The board being looked at certainly supports m.2 NVMe modules. For example the Samsung 960 EVO M.2. Those things are fast and go significantly faster than any SATA port could do. A 4x PCIe 3.0 connection gives a lot more bandwidth than a single SATA link, and NVMe avoids the SATA protocol overhead too. -- Len Sorensen
