Along with the paper launch of its first series of SSDs yesterday known as Pulsar, word from Seagate has also come in that they're working towards bringing out a series of "Momentus Thin" 2.5-inch hard disks for laptops which measure just 7mm in thickness, down from the standard 9.5mm.

Due to the smaller height, it's only logical that Seagate will stick to a single platter and of course use the SATA interface. Inevitably there will be 5400RPM models, but it's possible they will bring out some 7200RPM ones as well.

The new lower height drives will be ideal for laptop manufacturers looking to trim down next-gen portable PCs as much as possible. Seagate plan to officially unveil the new Momentus Thin series in Jan 2010.
