Hewlett-Packard Co. introducing a new business desktop PC that comes with a solid-state disk drive (SSD) to speed up Windows 7 and other applications. The 64GB SSD on the HP Compaq 6005 Pro will be used to store and run Windows and commonly-accessed applications. Available on Oct. 22 — the same day Windows 7 is officially released — the 6005 Pro will also come with a larger conventional hard disk drive connected via SATA interface for storing data and documents, said Martha Rost. HP calls the combo drive configuration its RapidDrive technology. The AMD-based 6005 Pro with RapidDrive costs $774, about $200 more than the $550 starting cost of the 6000 Pro, which lacks an SSD. The SATA-connected PM800 can read data sequentially at a maximum rate of 225.4 MB per second, and write it sequentially at 160 MB per second, HP said. Sequential data rates apply to large files such as movies or songs.
