Ask HN: Has anyone's M1/M2 SSDs failed?

I'm currently writing about 1.5 TB a day doing research and software engineering tasks. I'm considering buying a NVME enclosure and running the OS completely off that and not using the internal disk. It's a Mac Mini so the 10w draw of the enclosure isn't the end of the world.

Curious to hear if it's a real concern or if I should not worry.

    I've lost 2 M2 drives the first was 2TB Samsung 970 Evo which exceeded it's write endurance limit. Either due to firmware or me writing too much I'm not sure. The other M2 was a smaller Gigabyte drive that had some hardware failure.

    My new drive is a 1TB Samsung 980 Pro which has a write endurance of 600TBW so if I wrote 1.5TB a day it would last just over a year. I don't know how much endurance the drive in a Mac Mini has but I can't imagine it is any better than that. I would not want to write so much per day to the systems internal drive if it is not easily and cheaply replacable.

    Nope. My Mac mini m1 with the smallest drive that I bought the month they came out that I use every day is perfectly fine.

    If you mean ssds in general? I've never had a single one fail on me. My nas is all solid state with 4 sata ssds and 4 nvme m.2 drives as a big ol btrfs jbod and it's reliable as heck.

    My desktop has been solid state only. Nvme only for a couple years now.

    The only drives I've ever had fail were Western digital red NAS drives. I got 8tb of broken disks because rotating rust is horrible.
