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?

Not gonna lie, unless you have some specific workloads that require faster storage access you are not going to see much improvement by swapping in nvme ssd over sata ssd..

Since your board doesn't have m.2 slot, I assume it's rather old system and would probably get best performance boost by swapping CPU to faster one on same socket. You can probably find a 2nd hand fitting i7 for the same price you'd pay for the pcie card for m.2 slot. Also ram upgrade to 16gb or more (if not kitted already) could be beneficial

That isn't accurate. I used a PCIe adapter for an m.2 HDD on my wife's computer and she's getting 400% faster write speeds.

OP was speaking about "a small upgrade", most probably in general performance. 400 MB/s write speed won't make the OS itself any faster than with a normal SATA SSD.

I said 400%, not 400MB/s. 4x faster is definitely a noticeable upgrade.

@Anticorp @hemko does she need 400% faster write speed?
