I think Amazon has some reviews which could be useful. https://www.amazon.com/QNAP-QM2-4P-384A-Expansion-Low-Profile-pre-Loaded/dp/B07CVGZZCT
I would read the bad reviews vs the good to know what the problems are--and there seems to be quite a few.
QNAP HW in general has been quite problematic on the QA side of things from what I've both seen firsthand, as well as heard from second. If you get a well made piece of year, it can be dead reliable and awesome bang for buck - if you're not quite so lucky though... World of pain and suffering
(But a plx-equipped 4xNVME in a x8 form factor? Worth the $100 for most IMO lol)

Ah, so they did a 'direct from china' type of deal and got screwed over by good old bait and switch.

I already do own 2 of these and honestly they are not problematic. Few things to highlight though:
* 22100 is not an option. Neither shorter ff. There is single 2280 (small screw or plastic clip for recent pcb version) fixing point.
* FAN is i2c controlled. in other than native QTS/QuTS OSes there is no known way to control this little fan. i did some contribution to 0xGiddi and there is hope this might be changed soon but this may vary,
* A little care is needed during assembly to avoid bending the M.2 PCB too much, rubber feet are supplied to prevent this, and the heatsink has a spring-loaded mechanism to prevent excessive pressure,
* Both single-sided and double-sided drives can be used,
* No Bootrom option,
* Heatsink is made of aluminium, not copper.
* It draws about 9W itself (due to the PLX switch),
* it is LONG,
* 1.5mm thick thermal pads are included. Unfortunately, depending on the position of the drive controller (back/rear), part of it may not be fully covered by the heatsink. Never seen drives with controller far away on back. But just saying.
* The fan is audible when it ramp up, but the heat capacity of this heatsink isn't that bad and it usually occurs when several drives are scrubbed at the same time
* Drive replacement, if not done carefully, can damage drives due to bending (thermal pad sticks well and extra care should be taken when removing).
* Once assembled the overral weight make the card to bend after long time if it's assembled in horizontal position and it looks odd. not much but it hurts my aesthetic feelings.
Luckily i never had any stability issues, never found a drive that for any reason was incompatible.
Honestly i did not check ASPM capabilities, maybe someone else know.
Look also in here for more photos. Korean mindsets are always intriguing
cheers

Depending on what you're doing, something like this might make more sense Viking Enterprise Solutions U20040-02 2.5" High Performance U.2 NVMe SSD Module | eBay
Thank you for sharing this as I was not even aware something like this existed. What adapter do you use to connect this to your PCIE slot?
I used these: LRNV94N8 2X U.2 SFF-8639 SSD to PCI Express 3.0 Gen 3 X8 Card U.2 NVMe SSD Adapt
I really like those viking 4x M.2 modules. They have a 24 port PCIE switch so all the drives get x4 links. PCIe 3.0 though.

What on God's-Green-Earth is that thing? Four M.2's and a switch rammed in 2.5"? I almost want to buy a couple "just in case" I have some strange needs in the future. No idea those existed...
Yes!!! They are amazing. You can fit 16 m.2 drives in a x16 slot with a bifurcation adapter.
I have 16 optane 16gb drives I’m going to use to make the worlds most silly 256gb optane ssd.
I don’t know if they’d fit in a u.2 hotswap bay FYI, they are pretty thick.
16x pci-e -> 8x sff8643 plx cards. Most of my machines have u.2 stuff in some form or another so I didn't really need to add anything special when I found the viking things. The one thing to note about those is that to do take some power, and they really should be actively cooled. They get hot with out any m.2 modules in them.
Wanting to boot multiple OSes for benching purposes but not feeling like swapping M.2-PCIe adapters around whenever I want to bench GCN3, Turing or whatever.
Call me somewhat blind, but I see three (and not four) M.2 slots there. Where is the fourth?
