Seagate will present 7mm high hard drives at CES next month, these new 2.5" storage devices are 25 percent thinner than current models and are aimed at ultraportable laptops. The capacity of this new lineup is unknown.
Disk drives for laptop computers are typically either 9.5 millimeters high or 12.5 millimeters high. The thicker drives generally offer greater capacity because an extra 2.5-inch diameter storage platter can be accommodated inside. Recent advances in magnetic data storage mean more data can be crammed on to a single platter making the need for multiple platters less pressing in drives.
Seagate hasn't disclosed the capacity of the drive, which will be part of its Momentus Thin series, but it is already being evaluated by customers.
