It depends on what you consider "lots" of data. For >20tb yes absolutely obviously by a landslide. But if you just want self-hosted Google Drive or Dropbox you're in the 1-4TB range where mechanical drives are a very bad value as they have a pretty significant price floor. WD Blue 1tb hdd is $40 while WD Blue 1tb nvme is $60. The HDD still has a strict price advantage, but the nvme drive uses way less power, is more reliable, doesn't have spinup time (consumer usage is very infrequently accessed, keeping the mechanical drives spinning continuously gets into that awkward zone of worthwhile)
And these prices are getting low enough, especially with this NUC-based solutions, to actually be price competitive with the low tiers of drive & dropbox while also being something you actually own and control. Dropbox still charges $120/yr for the entry level plan of just 2TB after all. 3x WD Blue NVMEs + an N150 and you're at break-even in 3 years or less
- gknoy 1y agoI appreciate you laying it out like that. I've seen these NVME NAS things mentioned and had been thinking that the reliability of SSDs was so much worse than HDDs.
- kllrnohj 1y agoSSDs are just limited write cycles whereas HDDs literally spin themselves to death. In a simple consumer NAS usage, like if this was just photo backup, that basically means SSDs will last forever. Meanwhile those HDDs start hitting borrowed time at 5-8 years, regardless of write cycles.
- dotancohen 1y agoI have had two Sandisk 2.5 inch SSDS just suddenly fail. No warning that I could discern, and no way to recover afterwards. Both were while running Debian variants as a / partition, luckily I keep /home on a separate partition. Any idea what that failure mode could have been? It worries me tremendously to keep data on an SSD now.
- sandreas 1y agoI had a Samsung 960 Pro nvme fail without warning, that was even more concerning Then shortly after I had a BTRFS fail without failing Hardware on another drive Just backup your stuff with 3-2-1 strategy and you're OK. I'd recommend a combination of syncthing, restic and ZFS (with zfs-auto-snapshot, sanoid or zrepl) and maybe bluray (as readonly medium)
- dotancohen 1y agoI'm considering Amazon Glacier for offline backup. Any opinions, alternatives, or other advice welcome.
- sandreas 1y agoIsn't Amazon Glacier cloud based?
- dotancohen 1y agoYes, I mean for off site backup. It's too late to edit that comment.
