THE ARMOR A66 2TB & 5TB
The Armor A66 line uses a combination of plastic and rubber which actually looks nice. In terms of size the 2TB variant measures 139.2mm in length, 96mm in width and 16.2mm in thickness whereas the 5TB variant is 24mm thick.
To have a better idea about size i placed both drives next to the Armor A85 model i reviewed a while back (review here).
It may not look great but the wrap-around cable feature is actually very convenient.
The USB 3.2 Gen1 (AKA 3.0/3.1 Gen1) port is located at the front of the enclosures behind a small rubber cap.
These are the two WD Blue drives used with the 2TB and 5TB variants, at least at the time of this review.
