Method of providing data security between raid controller and disk drives

An information handling system, comprising:

• a processor coupled to a processor bus;
• a memory coupled to the processor bus, the memory communicatively coupled with the processor;
• a redundant array of independent disk (RAID) controller communicately coupled to the processor bus;
• the RAID controller including a plurality of keys, each of the keys including an algorithm to scramble/descramble data written to a disk drive in a RAID, wherein one of the keys selected from the plurality of keys;
• the selected key operably scrambles the data being written to the disk drive;
• and
• the selected key operably unscramble the scrambled data read from the disk drive such that the data is readable from the disk drive only by using the key to descramble the data.

A computer-readable medium having computer-executable instructions for a method of providing data security between a redundant array of independent disk (RAID) controller and disk drives in an information handling system, comprising:

• instructions for assigning a key from a plurality of keys in the RAID controller, the key operable to scramble data written to a disk drive in a RAID;
• instructions for scrambling the data sent from the RAID controller to the disk drive, wherein the scrambling operably changes the pattern of the data written to the disk drive such that the data is readable from the disk drive by using the key to descramble the data;
• instructions for storing the data on the disk drive;
• instructions for reading the data from the disk drive;
• and
• instructions for unscrambling the data received from the disk drive based on the key.
