SSDs still can't compete on byte/dollar. You can get 10TB of magnetic drives for less than $200 while that much in SSD will cost you several times as much. (

SSDs still can't compete on byte/dollar. You can get 10TB of magnetic drives for less than $200 while that much in SSD will cost you several times as much. (Certainly the gap narrows for smaller drives, and most users don't need that much space, so SSD by default makes sense.)

That’s true. But I don’t really care about the performance of my external hard drives. They store movies, photos, etc where as long as the hard drive can keep up with the streaming requirements - any hard drive can - it doesn’t matter. The other purpose is backups. Again if my backups are slow, who cares?

  > I don’t really care about the performance of my external hard drives. They store movies, photos, etc I care very very very much about the speed of the drive that stores my video files. I need to be able to open and seek through them quickly so I can find the clip I'm looking for. When you're working with ProRes stuff, this becomes a big deal. Luckily, good quality spinning hard drives can be fast enough, at least for my needs. Unfortunately, they're only fast enough when they're not running APFS. :(

      Good point—this conversation got a little muddled. I actually use either ZFS or NTFS + Tuxera for external drives on Mac, which works great (especially ZFS).

  Just listing a bunch of photos is going to have terrible performance on APFS. They don't need to make it work amazingly on hard drives, but they need to do some basic things like lumping together related metadata.

    What benefits do you really get from using APFS on external magnetic disks that are really so significant that you wouldn’t just use HPFS?

      Snapshots are always good.

No but these are low end machines, the bottom of the range. There is no option to upgrade them to 10TB.
