Seagate ships 5mm Laptop Ultrathin hard drive to ASUS, Dell and more

Western Digital may have been quick to release a 5mm hard drive, but it doesn't have a lock on the category: Seagate is entering the fray by shipping its own slim disk, the Laptop Ultrathin. Like its rival, the drive stuffs as much as 500GB of conventional, rotating storage into SSD-like dimensions ideal for Ultrabooks and some tablets. It even costs the same $89 as its WD counterpart, although we're more likely to find the disk built into our next PC than pick one up as an upgrade. Both ASUS and Dell have chosen the Laptop Ultrathin for new models, and we suspect they won't be alone.
