STORAGE DEVICE RAID DATA WRITE INTERMEDIATE PARITY SYSTEM: abstract simplified (17716204)

• This abstract for appeared for patent application number 17716204 Titled 'STORAGE DEVICE RAID DATA WRITE INTERMEDIATE PARITY SYSTEM'

Simplified Explanation

The abstract describes a system that uses a storage device with a volatile memory system to store data. When the system receives data from a host system, it first stores it in the volatile memory system. Then, a portion of the data is stored in the storage system, and intermediate parity data is generated using that portion of the data. The intermediate parity data is also stored in the volatile memory system. Finally, the portion of the data is erased from the volatile memory system.

Original Abstract Submitted

A storage device RAID data write intermediate parity system includes a storage device coupled to a host system and including a storage subsystem and a volatile memory system. The storage device RAID data write intermediate parity system receives first primary data from the host system, and stores the first primary data in the volatile memory system. The storage device RAID data write intermediate parity system then stores a first subset of the first primary data in the storage system, generates first intermediate parity data using the first subset of the first primary data, stores the first intermediate parity data in the volatile memory system and, in response, erases the first subset of the first primary data from the volatile memory system.
