EasyStore is essentially a WD Elements rebranded for Best Buy so they don't have to price match. It's USB 3 and I got transfer speeds of 120 MB/s compared to 40 MB/s with my USB 2 external drives. It's one 18 TB drive so not trying to do some internal RAID 0 to make two cheaper drives look like a big drive. Doesn't have a power button but will spin down if idle (kind of means don't leave it mounted when not in use). $400 or so new though I assume my brother bought it when it was like $200 at a steep sale (WD EasyStore 20 TB is $880 currently showing how much HD prices have gone up).

On the negative I have two and they both have this high pitch whine when the HD is spinning which make these drives impractically to leave mounted all the time but I only use them for backups so that's fine with me. It also comes with WD Discovery software, though you can also get that and more from WD's Software Downloads page but looking at that page I'd rather rely on my macOS system utilities.
