Quote: Most notebook computers include just one bay for a hard drive, so you obviously need your boot drive to also handle your storage needs. This has meant that you either had to compromise on performance or capacity when choosing between an SSD and a traditional hard drive. The Seagate Momentus XT hybrid drive is the solution to this problem.
