Most SATA and NVMe SSDs have a PBW or DWPD number that gives you an
indication of how long it will last. These numbers are usually normalized
to a JEDEC workload. From that you can often extrapolate to your workload
if you know it well enough... It is one of the things I evaluate for
SD and CF cards almost never do unless they claim industrial use. Ditto USB
sticks, but with more industrial models available.
