I can't exactly judge considering I just loaded the manual up myself
. M key 2280 is pretty standard but on that old a chipset there are some caveats.
Your m.2 socket shares bandwidth with PCIEX1_1 & PCIEX1_2. These are both PCIE
2 slots. It is unclear, but unless the m.2 slot has two lanes of its own to add on that might mean you
only have two PCIE
2 lanes available in that slot. The standard now is
four PCIE
3 lanes which works out as something like four times more available bandwidth. Best case, you've got half the peak throughput, worst case: a quarter.
Why am I mentioning this? My initial reaction was to suggest better SSDs out of the bunch and tell you to ignore the crappy ones... but if your bandwidth is really nerfed like that you may not see any real benefit to the more expensive ones. You'd be stuck in a limbo between SATA 3 and the speeds we expect from NVME.
Relevant thread, with a workaround expansion card, though lacking specific performance figures.
Quick summary given the info I've posted above:
The WD Blue & MX500 you've linked are both basically SATA 3 drives. The 2.5" form factor SATA drives of the same name are equivalent.
The SN550 is an NVME version of that WD Blue and worth a look, but perhaps not for the price the 1TB drive seems to cost.
The Adata and the Sabrent Rocket are both a couple of tiers up from the SN550, but different controllers. QLC is still inferior in most cases. Might work for you if it saves money considering you're likely limited for peak throughput anyway.
Pretty sure that rocket is more or less equivalent to other Phison E12 drives, with the main differentiator being the warranty. Of those, I personally picked the Corsair MP510, but it doesn't look like the price has come back down to parity with the others again.
I don't have a good overall suggestion for you without knowing what you'd like to do about the first half of my post
