If you want to replace an apple ssd with a cheaper, better NVMe one, you can
buy an adapter to do just that. I just did that and strangely enough, even
though the original was a SATA, the NVMe device works fine.

If it is cleaned of oil, you can use a magic marker or Sharpie.
DyKem is a layout

Try a Sharpie pen. All you are looking for is it gets worn off or not.

Not really, Dykem is a marking out fluid rather than a contact testing
compound.
You can see
Is the angle between the cheeks (what is the right term?) of the pulley 34
degrees? If so using a tool with VCMT inserts fed straight in might work.

I use SSD's in everything. I have had 1 fail. It was an A-DATA brand.
I have an intel somewhere that is OK and majority Samsung drives, both M2

Be aware that M.2 is a socket spec that includes both SATA and NVMe type
devices.

Added to that, Apple began using PCIe drives before the NVMe standard was
established, so there’s another socket to be confused about if you run Mac.
Don't buy cheap or used SSDs, my experience is that those fail too
early. I only run Intel or Samsung and have not had a hard failure in
around 10 years.

Your results are atypical. It could be however the fault of the OS. Each
bit in an SSD has a certain number of read/write cycles before it might
fail. Some million of cycles. Back in the "old days" some OSes would
write continously to the same place on the drive. For example you'd
