As clearly stated by its name the Seagate Seven portable hard drive is just 7mm thick so amazingly as it may sound to some of you (or most) it’s actually as thick as an 2.5″ internal HDD/SSD. To accomplish that Seagate had to use one of their latest and most advanced SATA III drives and more specifically the 2.5″ Laptop Ultrathin model (ST500LT032) which measures slightly over 5mm in thickness, can spin up to 5400RPM, has 16MB cache buffer, supports NCQ, has very low power requirements (less than 2W) and is virtually inaudible thanks to its Fluid Dynamic Bearing (FDB) motor.
