<p>A data storage device includes two data storage media: both a hard disk 8 and a non-volatile solid state memory device 7, such as a flash memory. Data received by the data storage device for storage is stored both in the hard disk 8 and the flash memory 7. Since the data storage is duplicated, if a problem arises with retrieving data from one of the hard disk 8, the data can be retrieved from the flash memory 7.</p> |
