I actually agree that mechanical drives have a place for usage still.That sounds lovely, and I would be happy to when SSDs can reasonably replace HDDs for bulk storage.
But as I said above, it's not in a high end case like that which already has limited air flow and potentially a lot of hot things, with zero easy access.
I have 14TB of spinning rust in one enclosure, (and a ridiculously old 500GB RAID0 Lacie portable with dual 2.5" spinners that I bought over a decade ago) connected to my Mac mini on a shelf under the desk.
Any meaningful space for that sort of drive in a thousand dollar case, needs to be hot swapped, and realistically if your needs are "10TB" but you don't want to use M2's, a USB3 10TB unit will set you back maybe $200.
The only use-case I see for mechanical drives, that has any kind of cross-over with people who are willing to pay $1K for a case like this are:
- backups, because the speed is (mostly) kind of irrelevant after the first one and the cost/$ ratio buys you a longer safety net with incremental backups.
- ridiculously mass storage.
The first case doesn't make a lot of sense with an internal drive.
The second doesn't make a lot of sense with anything less than 4 drives.
