What's my best bet for cost-effective and convenient external local storage? I have a ton of photos and large videos which are consuming tens of GBs on my main computer's hard drive. Just get a cheap thumb flash drive?
Alternatively, you could get a handful of flash thumb drives and back up onto all of them, syncing with a different one each week/month/whenever so that they're all getting continuously refreshed and you'd have snapshots in case you accidentally delete something and that deletion gets synced to the most-recent drive.
Also...holy shit, I haven't kept up on how precipitously prices for storage have dropped. Just saw a 10 TB external drive for only $150!
