Though it can be surprising to find out how they've used a drive. Such
as a 4TB WD MyCloud that provides that 4TB using two 2TB partitions on
the *same* drive, using RAID to make them one 4TB. I dunno why they'd
do it that way.

If you control the hardware you get more options. I've opened up dozens

of older drives to destroy platters, and they all had one actuator shared by

all the heads. Maybe the WD drives have two actuators, so are effectively

2x2TB drives on one case. This has been investigated in the past:

and wasn't cost effective, but now we have:
