So, I went with 2x corsair mp600 force drives.

I know not enterprise stuff. But I checked what I’ve written to the samsung drives and over the time frame and I don’t tax them too hard.

The new drives have 1800tbw endurance. Hopefully won’t die unexpectedly.

Couldn’t justify the cost of even second hand enterprise drives in Australia. PC parts here are ridiculous.

Thanks for the comments.
