From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Are there any pitfalls to avoid in buying PCIe/m.2 adapters? (feddit.de)

I'm planning on giving an older machine a small upgrade with an SSD, but since that machine does not have an m.2 port, I was thinking about buying the cheapest PCIe adapter I could find. Besides the obvious stuff like ports, PCIe gen and lane count, is there anything I should look out for? Specifically regarding Linux?

Get as slow as you can, pcie 4 nvmes get pretty toasty and without proper cooling they will throttle anyway. Either that or make sure you get cooling options.

Not all adapter cards are the same or will run every ssd in every motherboard. I have half a dozen of those things because one brand will work in one computer with one type of ssd and not in any others.

If you get one with multiple, make sure your motherboard can split your pcie lanes so you can access all ssds on the card. Or find one with a pcie switch, though that can slow things down if you are not careful.

Stay away from dell and hp branded stuff unless it is going into a dell or hp. Dell made this awesome four ssd card with fan and everything, can only get it to run in dells.

I heard of bifurcation in that context, but how is that called in "mainboard spec lingo"? What buzzword should I worry about?

It's a Dell, so I'm safe here.

Somewhere in the bios will be a pcie option, it will look like “4x4x8” or “8x8” or some combination of the like. Most dell workstations and servers have this option that I have run into. If you don’t see this in the bios then you will only be able to run one nvme ssd
