With a profile of only 9.5mm it is ideal for integration into premium notebooks, high-end PCs and portable external hard disk drives. The 2.5-inch HDD’s operation speed of 5,400RPM allows a fast internal transfer rate of up to 1,363Mb/s and provides a market-leading areal density of 541.4Gbit/in². This extends its possible uses from high end personal computing and data storage into the set-top box and Personal Video Recorder segments.
