A hybrid hard disk is one which combines a ordinary hard disk with a new and faster storage medium (typically flash memory) to provide faster access. Until now , the few hybrid HDD’s that were proposed / developed contained an inbuilt small amount of flash memory typically less than 500 Mb, which cached frequently used data to speed up the data access.

SilverStone Technology has introduced a different set of technology, essentially using a HDD instead of using a inbuilt , limited flash memory, called aptly as HDDBOOST. According to company this makes for a 70 % faster than a traditional hard drive.

How it works – The flash memory basically creates a mirror of the hard disk so that all read access can be made to the SSD, and this make it almost 10 times faster than a normal hard disk. However the actual magnetic HDD is still required to store any changes made, and to reduce the number of writes to the SSD.
