I had a Dell PC with mSATA drive, it also had Ivy Bridge CPU. I recall
Gigabyte mainboards with Ivy Bridge chipsets had mSATA slot.
I have some Haswell and Skylake PCs; them and none have mSATA.
mSATA was never very popular on desktops, where there was plenty of space
for 2.5" SATA drives. Any mSATA drive can be trivially adapted to the 2.5" form factor.
It was more popular on laptops where a 2.5" was too big.
If you can get a SATA M.2 drive there might be a passive adapter to mSATA
out there.
I think that as soon as M.2 got in to the business of multiple lanes it became redundant.
mSATA was more popular in the early 2010s before NVMe came to market - it
took a while before OSes, BIOSes, etc supported it. eg I have a Haswell E3 server and it won't boot from NVMe. I think Win7 and 8 as released won't
work out of the box on NVMe - to install them you need additional drivers.
M.2 SATA has never supported multiple lanes, it was only M.2 NVMe that used
it, but it had to wait for drivers to be commonplace.
(an even nicher niche was M.2 AHCI SSDs - used a PCIe interface but looked
like a SATA controller to the OS. They went away after a couple of years,
but for a long time MacOS only supported them and not NVMe, because they shipped in 2013-2015 Macs)
The M.2 SSDs can outperform off board SATA 3.0 drives by some margin - I
have seen figures around 40 GB/S quoted by some motherboard makers.
PCIe Gen5 only goes up to 14GB/s, so that's off - do you mean 40Gb/s?
