Good m.2 ssd for write endurance (alien.top)

Looking to use an m.2 drive as a boot drive in an r740xd. I won't be using it for cache so write endurance isn't critical but I would still like something that will last a long time.

Seems like some form of mlc drive would fit the bill such as a 970 pro. I don't mind shelling out a bit if it means I won't have to migrate boot devices during the life of this server. 1-2TB is adequate for me.

Looking for other recommendations. I've heard optane is quite good but that seems to be overkill for my use case.

Look at the new E18 pSLC drives on DigitalSpaceport. They're being bought up by the Chia and ZFS crowds because of high sustained writes and write endurance. They come in 320GB and 640GB versions (essentially 1TB and 2TB models, with pSLC firmware).

From what I understand the first batch is almost bought out, but eventually they have enough of them to be selling through Amazon as well.

But if this is a boot drive... you don't need anything special. You're going to use like 1-2% of its rated TBW per year: so any warranty would time out well before you hit endurance limits. Buy a midrange consumer 2-4TB NVMe on Black Friday and be done with it.
