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.
Define expensive in this context. I think I have this one (~$20): https://www.asus.com/us/Motherboard-Accessory/HYPER_M2_X4_MINI_CARD/
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.
My x99 MBs (24-months or newer) have a small connector to plug that into. One has the SSD lay parallel to the MB. One has it stand up vertically away from the MB. http://www.legitreviews.com/wp-content/uploads/2014/08/m2-slot-645x443.jpg But those MBs accept 64GB and 128GB of ram respectively. I will be shocked if your MB that only takes 8MB of ram has a native M.2 connector. I think you will need something like: https://www.pccomponentes.com/silverstone-ecm21-adaptador-m2-a-pcie-x4 Look at the picture. There are no active components. Basically all that board does is convert a normal PCIe MB connector to the M.2 connector used by NVMe SSDs. If the adapter says it has "M.2 SATA" support, run and hide. You want M.2 PCIe or M.2 NVMe support. To boot off of a M.2 NVMe SSD requires bios support in the MB. Using it as a data drive doesn't as far as I know. (But I've only tried it with newer MBs.)
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.
It's primarily expensive because of "480GB". If you want that much capacity it will cost you well above $100. If you're only doing this to address swap space, you should be able to get it done with a 128GB SSD. Around $100 for the SSD / adapter card pair.
