True. My rule of thumb, anything over 4TB, 7200rpm or not - I use only for long backup. Not on production app that needs good IO speed.

- white-flame 9y agoHigher capacity drives often have higher platter data rates, because of the increased density (or more platters & heads) at the same rotational speed. They should have better I/O throughput than 4TB drives... as long as they're not SMR. :-P A SMR drive that takes multiple days to transfer 500GB to it isn't useful as a maintained backup either.
- phil21 9y agoSMR drives really aren't intended at all for single drive applications. Get 512 of them in a giant pool (especially if it's SMR aware) and the throughput issues start to be less of a concern for certain applications. Anything write intensive of course means you immediately look elsewhere.
- loeg 9y agoThis is kind of a non-sequitur. SMR drives have vastly worse performance than non-SMR drives. Neither RPM nor capacity has anything to do with SMR or non-SMR.
