However, the difference was not in just branding which to me was surprising. In Elements the drive is held by rubber brackets which won’t fit in non-WD drives, but Easystore is using rubberized screws, which allowed me to use the case with older Seagates.
They do run hot in the external case. I was trying to run badblocks and when the temp became about 60C, I decided to run an external fan. I wonder how long do these drives last in these external cases.. In my NAS with fans, the highest it got was 49C
Some WD external drives will hang the boot process if the host computer probes the drive for bootability. These drives will even stop the host computer from booting if they're connected via USB, much less if they're directly connected.
Some USB external drives have the USB controller embedded on the drive PCB and don't provide an accessible SATA interface.
As of writing this comment, big external drives still come with 3.5" hard drives, with the only caveat being that some require you to disable the 3.3V rail on your SATA connector, either by cutting the wire or taping some pins on your HDD with kapton tape. Without the workaround some of these shucked drives will not power up properly when connected to a SATA power plug that also provides 3.3V.
