Tangent: what's the cheapest 4TB+ PCIe SSD without significant known issues but with hardware encryption? The SN850x seems to have its own issues, and beyond these everything else seems so expensive.

Re: Update on Samsung SSD Reliability
#92Apparently a few months ago it became known on the Chinese internet that the 980 Pro, 970 Evo Plus with new controller, and OEM versions are prone to getting unreadable sectors, where SMART 'Media and Data Integrity Errors' increases on every read attempt. https://www.reddit.com/r/buildapc/comments/x82mwe/samsung_ss... https://www.reddit.com/r/DataHoarder/comments/x8arle/psa_sam...

My anecdata: tl;dr: All 3 of my Samsung M.2 NVMe SSDs have failed in less than 3 years. 100% failure rate. My first SSD was a 1TB Samsung 970 EVO. It failed after 2 years and 8 months. It was replaced under warranty with a 1TB 970 EVO Plus. That replacement has now also failed after 1 year and 9 months. I bought a 2nd 1TB 970 EVO Plus in May 2019. It has now also failed (2 years and 7 months). Both are expected to be…
I've bought 6-8 m.2 Samsung 970 EVO Plus and 980s since 2018, and none have failed to date.
Anecdata is the worst, I'm sorry to hear about this happening to you. It's surely frustrating and upsetting.

#93The real problem is OS:es that write to disk for no good reason. Windows 10 writes 100KB/s constantly. That should be illegal.
Do we know the location of those writes, perhaps they can be redirected to a ramdisk?
Sysinternals tools will show up the writes and what is causing them.
I've dug down and found random things doing dumb stuff in the past. Verbose logging turned on by default for some services, for example.

#94I really want to see ssd manufacturers offer a decent warranty... This drive costs $100, and will last 10 years or until 100TB has been written to it, as long as you keep it within the specified temperature/humidity/power conditions. If it fails to do that, we will return $1000 to you.
I am not sure why you want a 10x refund, but it seems like your request is easily met by current warrantees. A 1TB WD SN850X advertises 1200TBW endurance, rather more than you require.
The SN850x seems to have its own issues from what I read (just google it).

Perhaps an insurance agent can craft a policy to do that for you.
Failing that, maybe a bookmaker.
Re: Update on Samsung SSD Reliability
#96every machine I have that can fit 2 SSDs (basically, everything except the very slim laptops) I have converted over to running a ZFS mirror as its root filesystem. NixOS makes this very easy to do because the grub.mirroredBoots option [0] removes the need for a separate "bootpool" with limited ZFS feature flags.
and crucially, I always make sure they're 2 drives from different manufacturers, so that a bug of this nature should never be able to take down both drives in a pool simultaneously.
I think of this as the "if you're going to go to the trouble of wearing a belt and suspenders, make sure to buy them from separate brands" principle.

Re: Update on Samsung SSD Reliability
#97I have this exact model, 980 Pro 2TB. It says to update firmware, but how can you do that from Linux? The instructions are all about some Windows program. Thanks! EDIT: I'm quite happy with the warning from this article, fixed a potential future problem!
an example:
nvme fw-log /dev/nvme0
nvme id-ctrl /dev/nvme0 -H | grep Firmware
nvme fw-download -f firmware.ebin /dev/nvme0
nvme fw-commit /dev/nvme0 -s 2 -a 3
nvme fw-log /dev/nvme0
Re: Update on Samsung SSD Reliability
#98I've been trying to find a decent endurance NVME in the m.2 form factor for write-heavy applications and it appears that true 2-bit MLC has all but disappeared, replaced by 3-bit TLC and higher (with commensurate loss of endurance) The high endurance SSDs appear to be only available in u.2\u.3\hhhl and god-help-me EDSFF form factors Any suggestions? Micron's 7450 isn't readily available
Why not get a U.2 drive and an adapter like this one https://www.startech.com/en-us/hdd/m2e4sff8643

They don't really make them anymore, but you can still get m.2 form factor Intel Optane SSDs in the 900/905P series, example[0]. They have insane endurance specs. Their performance is also still awesome, especially for random reads/writes[1]. I wish they had continued making them. Most PC builders just bought crappy Samsung SSDs this whole time, ignoring these awesome (and high priced) drives. > Life Expectancy 1.6 m…
Most PCs experience very little write load; I can imagine that many of them experience less than one full drive write per lifetime.
A database server box, or even a CI build box, is a whole different business.

Is it possible that your motherboard or PSU is killing the drives?
Could also just be sheer chance, of course.
