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?
They’re some boot issues using the adapter. I had some difficulty getting the BIOS to identify the adapter as a bootable HDD. Unfortunately I don’t remember how I solved it, but it was solvable. But you asked for potential pitfalls, so there’s one. Heat is also another issue. You don’t need to pay 200% more to get a NVMe drive with a heatsink already installed, you can just buy a normal NVMe and slap a $5 heatsink from Amazon onto it. I did that and it worked well.
Unless your buying a superspeed pci-e gen 4 drive you really don’t even need a heatsink for most drives.
Haha) me trying to fit pcie gen 4 ssd into pcie gen 1 motherboard)
If your machine doesn’t have UEFI, only a few early NVMe SSDs are bootable, for example the Samsung 950 Pro. If you can’t find one, you could try installing the bootloader on a USB stick.
It’s not that old and currently UEFI boots from a SATA SSD.
Maybe let’s start with what the board+CPU is and we can make more informed recommendations. I do tend to agree with many posters in that in boards that don’t already have an NVMe slot, adding a card for NVMe versus performance gains (against an SSD) may not be worth it.
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.
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.
