To accommodate the Constellation's four-story stack, Seagate uses a drive casing that measures 15mm in thickness.
Seagate brings terabyte capacity to 2.5'' enterprise storage

I understand it's geared towards server, but 15mm is just stupid when there are already 1TB 2.5" drives that are only 12.5mm thick.
