As I posted above, SMART 177 isn't a percentage, it's a P/E count. Documentation claims 2000 P/E cycles, independent testing shows close to 6,000. It's far less than even 1% used.

You're absolutely right. I wonder what other SMART values will be really important to SSD's.
Where is blackblaze's SSD data. My guess is it will be even more vendor specific as it is now.

Well no.. You're at 8 write cycles used, and 99%.

Right that value represent the raw maximum erase cycles (~3.000 cycles TLC, ~10.000 MLC, ...)
Let me quote wikipedia:

173 0xAD SSD Wear Leveling Count Counts the maximum worst erase count on any block.

Now my own raid0 drives:

To be fair you've written ~950 GB and used 8%. If we simply extrapolate that you'll get ~12 TB or about 100 full drive writes.
Personally I'm also dissapointed in the consistency of the TLC NAND drives.
I get performance degradations on all my Samsung drives even though I've applied all the performance fixes.
I can't fathom though why you are putting the smallest (slowest) and cheapest drives in your server.
A Professional SSD (Sandisk or Intel) would be a lot more appropriate.

I don't think that there's any evidence that the linux swapfile performs better - and in any case why would it being unfragmented be an advantage? Memory access is random, and so swapfile access is random, and so why does having it non-contiguous cause an issue?

That's exactly why you want a swap partition at the start of the drive where seek time is as low as possible.
You don't want a bad situation (swapping) to become even worse (swapping and seeking all around the drive).

That's not true, they are not eliminated. There is plenty of crappy kernel mode software out there (drivers, filesystem filters).
And the following (mostly hardware) problems also often cause BSOD's:
- Overheating GPU's.
- Broken stick of RAM, often due to dusty working environment, overheating
or abuse.
- Bad Hard drive causing corrupt system files.
- ACPI Power issues (hibernate,suspend,...).

Now most of these problems do crash all systems.
But personally I find the kernel panic and short stack trace on the console a lot more helpful
than the BSOD (not counting the MEMORY.DMP or Minidump files since these need windbg).
