Is this a desktop? If so, for ~$20 you can buy a NVMe SSD controller card. It fits into a PCIe slot. (Assuming you have an empty slot).
I have free slots, yes, but I don't remember the kind.
NVMe SSDs scream. Mine benchmarks above 1.5 GB/sec. (That's B for Bytes, not b for bits). I have openSUSE 42.2 running on it. But I have plenty of RAM, so I don't think the PC ever swaps.
Not as fast as RAM, but 10x the speed of rotating drives even if you ignore seek times.
I have 2 of the NVMe SSDs. One was way expensive (2 TB).
But the Samsung PM951 128GB is under $100.
Interesting, very interesting. Does one need both a controller card and the SSD?
Yes, you have to have both a NVMe SSD controller and a NVMe SSD.
The last 2 MBs I bought had integrated NVMe SSD controllers, so for them I can just buy the SSD and plug it in directly to the MB. I can also boot off of the NVMe SSD. I don't think you can boot off the card based controllers.
Here's a picture so you know what you're looking for:
I don't know the above vendor, but there should be various sellers of a controller card.
I forgot to say that you can get both NVMe and AHCI SSDs in the M.2 form factor.
You want to get the NVMe if possible.
As far as I can tell the AHCI version were a short lived stepping stone to the full NVMe version. Others might correct me on the details, but regardless go with NVMe.
I see that the cards are pretty expensive. I see this, though: Samsung 960 EVO NVMe M.2 SSD PCI-e 250GB 134,95€ https://www.pccomponentes.com/samsung-960-evo-nvme-m2-ssd-pci-e-250gb The link is in Spanish, but you can see the photos. I understand this things connects directly to a "PCI Express 3.0" interface. I'll have to check whether I have that. There is one on plain PCI, but very expensive: https://www.pccomponentes.com/kingston-hyperx-predator-m2-ssd-480gb-adaptado... Kingston HyperX Predator M.2 SSD 480GB + Adaptador PCIe 344,59€ It is a combo with a PCI to PCI-e interface, then an SSD in M.2 form factor. Another solution, but expensive. -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)
