Yes, this bit me just last month. Around October 2022 I purchased 3 Samsung 870 EVO 2TBs for use in a RAID array. By January 2023, all three of them failed within a week of each other! Fortunately they failed one by one, so I was barely was able to recover my RAID array by pulling out one drive at a time, powering the computer off, and waiting for the RMA replacement to arrive. But imagine my shock to see one drive f…

A perfect example why RAID ain’t backup

I'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

I 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.

This sounds like an SLA agreement, its very unlikely you'll get that for 100 bucks. Even if this manufacturer somehow perfected their process and have zero defects, they are still acquiring a 10 years liability for 100 dollars of revenue.

While it's true that MLC is mostly dead, you might want to consider a higher capacity TLC ssd. If you double your capacity, you double the endurance since SSD endurance is in drive writes per day, and a bigger SSD will likely have a bigger SLC cache to help with the write speed.

APC sell surge protectors with equipment protection insurance for less than $100. Apparently, it's possible even for products sold at $100.
