Description

technical field

[0001] The present invention relates to a data storage device suitable for application to, for example, HDD array units and a data storage method thereof. Background technique

[0002] In recent years, HDD (Hard Disk Drive) array units have been frequently used to store AV (Audio / Video) data in broadcasting stations and post-processing. In the HDD array unit, a plurality of HDDs are installed into a single unit in order to realize both large-capacity storage and high data transfer rate.

[0003] For example, huge storage capacity, high reliability, and high data transfer rate are required for AV servers used as nonlinear editing systems in broadcasting stations, so HDD array units are used as storage. Such an AV server has a plurality of recording / reproducing ports each of which inputs and outputs data streams at a high bit rate during operation. The requirements placed on the AV server include: (1) absolute reliability in preventing video or audio streamin...
