i’ve decided that using nvme for backups (in addition to hdd) seems like a reasonable way forward, for many reasons, but i read a lot of conflicting information about them.

i have a 224TB thunderbolt raid 5 archive of hdd which i intend to continue using as my main consolidated archive, but it’s mostly offline because of the noise, power use and also for security and durability/longevity. it gets used once a week or fortnight to update the archive with new work and serves its purpose well.

i also have an 8tb nvme m.2 as a working drive for current projects but have recently been pondering the idea of moving additional backups on to 1tb nvme’s (this is in addition to the RAID archive; have been using additional bare sata drives for last 20 years and have waaaay too many) because they take up such a small amount of space and are quiet and easy to work with.

what is the latest opinion on archival storage of m.2 nvme ssd’s? if i only write to them once and then store them offline, will they store well for 10 years? (probably something like a crucial p3 budget wise) some reports say 1-2 years, 5 years and some older at 20 which seems doubtful. do they need to be periodically powered up?

thanks in advance, any thoughts appreciated.
