Seagate, which purchased Samsung's HDD division in 2011, has begun shipping the world's thinnest 2 TB hard drive. The Samsung Spinpoint M9T, which comes in a 2.5-inch form factor, measures 9.5 mm thick, giving notebooks a bit more storage space.
While not as thin as Seagate's Momentus Thin and Laptop Ultrathin HDDs that are just 7 mm thick, both those drives top out 500 GB, while most 2 TB HDDs on the market stretch the calipers at 15 mm. The Spinpoint M9T's thickness makes it compatible with the 9.5 mm standard used by the majority of laptops.
The drive includes a SATA 6 Gb/s interface and boasts an average seek time of 12 ms and maximum data transfer rate of 600 MB/s. A 1.5 TB capacity model is also available. However, because the drive is currently sold directly to original equipment manufacturers, pricing details aren’t available.
