I have this laptop from like 2012 that I use a lot and I can even say it's my main Linux machine. It's got 8 Gb of RAM and a dedicated GPU so it's not bad but it has an HDD so slow it takes what seems to be 30-60 seconds to launch a web browser. I guess it's 5400 RPM. I want to finally buy an SSD for the machine.
However I noticed that all of the brand new ones that are available in my area are either SATA3 (for SATA) or PCIe 3/4 (for M.2). The laptop obviously supports none of these standards.
Will such an SSD work or do I have to search for a used one with an older standard (like SATA2)? Adapters might be a problem to get because I'm not a customer of marketplaces I can get them from so I'm afraid of getting scammed or just not figuring out the purchase procedure.
I can't give any first-hand experience, but this article:
https://www.technewstoday.com/sata-2-vs-sata-3/
says that all SATA generations are backward and forward compatible with one another. If the physical connector fits, it should work. Just at the lower speed of the controller.
Thank you, mister/miss. This is very helpful.
