Hi.
$12.50/each for 32GB is good. These M10 modules abound on AliExpress.
These older optane modules are not that great. The sequential speeds are well behind what even NAND Gen3 drive can do.
The random write perf is better than NAND drives but not nearly as good as the more modern optanes.
Unfortunately, the size is so small, they start to become too tight even as a boot device.
At 32GB, I could see this being used as SLOG device for HDD pool, or if you have a small db where you mostly perform low QD random access.

I'm planning on using one for a boot drive for pfsense with one of theese $65 pc Pardon Our Interruption...

What they are really good for is very useful LIVE Linux boot drives, paired with a good 10G/20G USB 3.1/3.2 to NVMe enclosure. Enough space for a few different LIVE Linuxes (see YUMI UEFI) and really snappy for that use case. Not the cheapest option for a LIVE USB drive, but a really good one, that will last.
Taking into account, that you can get RTL9210 based USB enclosures for as low as about 6,-EUR now on Aliexpress, you could get a nice USB drive for a reasonable price. And it would outlast any of those cheap USB standard crap with subpar NAND on it.

These are PCIe (x2 I believe,) but if you just need something reliable for SATA Intel's old product catalog still has something for you, the s3500 in m.2 form factor, for instance: Intel DC S3500 Series 340GB M.2 SATA 6Gb/s Internal SSD SSDSCKHB340G401 | eBay (no idea if that seller is good or anything, just the first one which came up.)these are pcie, not sata, right? i could use some durable boot media for my opnsense box, but it only has a sata m.2 slot
Edit: I didn't realize they made an s3520 in m.2 as well, newer and still has PLP, costs less if you don't need the extra capacity: Genuine Intel SSDSCKJB150G7 DC S3520 Series 150GB SATA MLC M.2 SSD J57264-000 | eBay
Not all sellers list these in a way that's easy to differentiate from the 2.5" versions so searching the full part number or subsets of the part number may find you better deals.

Throughput is limited and endurance is not that great, due to the small size. Fine cheap boot drive, not useful for data.
For an HDD array the throughput (in a home setup) might be limited anyway. And at about 10,-USD per piece, you could even replace it every year. But you probably will not have to do that in such a timespan, anyway. So, I think you should see it in the correct relation.
Yes, it is not top notch, but then again, it is only ~10,-USD, as already mentioned. What price range are we talking about for better options? That is the right question at this point. And I guess the answer will include a price, that is several times higher.

You can get a 256gb nvme ssd on ebay for $15-$19 that will be a lot faster. I bought them mostly for the cool factor.
Do these 'act like" USB thumb drives? I have a NVMe USBc enclosure now that shows up as an external hard drive. Most of the time that still works, sometimes it leads to issues with what various software/bios' "expect"
I agree with this infact I have been using SK Hynix BC711 256/512GB as 2230 boot drive.
Endurance on a 32gig is 182TBW, on paper
SLOG usefulness is VERY situational however, and for spinning rust I'd go with the even cheaper 16GB. IIRC the formula is ~1GB of space per Gb of network transfer speed. it only helps with SYNC writes, so limited use for most of us.
FWIW I have abused the HECK out of a 16GB one, ~100TBW and it reports as very healthy still.
For boot, logs, pagefile these(even the 32) outclass even multi TB drives in 4k random r/w. They also don't seem to suffer the same write amplification issues NAND SSDs do, where the TBW on those assumes "best case" writes (not 4k random).
the 32 and 16 GB also idle real low, 1w. great for shoving in smaller things

There is no point to agonize over the cost when it's so low, at that level it cost more to ship that the item itself.
If endurance is the only concern, you are better off buying a larger NAND SSD and only use a fraction of it.
If you use 1/10th of NAND SSD, the effective endurance of used portion is 10X of the original endurance.
Actually, is much more than that. Given that the SSD controller will be able to distribute random write operations easily (that's the operation that's really taxing from an endurance POV).

No PLP = not suitable as SLOG, full stop.
As @Mithril said, ZFS SLOG duty is a very, very, specific game where the most important criteria are: PLP, low write latency, and then endurance and write throughput; reads are totally irrelevant. If you're in that game, you should be able to spend $100 for a 100 GB DC P4801X.
Oh?
These are rated for 365TBW
That's... 11,680 drive writes.
6.4 drive writes per day, every day, for 5 years.
There are 2TB QLC drives with less TBW than that.
The only problems with these drives is their size and modern cost.
They are fun toys. Curiosities.
I wouldn't pay more than ~$5 each for them though unless you have a VERY specific use case where they excel.
Note: I have several of t he 16GB drives. I bought 10x for $20 shipped. I used them as boot drives for some older laptops and it was...fine.
I bought like 8x of the 16gb ones forever ago and the seller sent me like, 40 lol. I’ve been using them for random SBCs and silly arrays over the years, I think one was DoA otherwise they’ve all been totally rock solid. Not like I use them that hard though.
