Abstract:
A method for reading data stored in a redundant array of independent disks (RAID). The RAID includes a RAID controller, a first cache, and a hard disk including a hard disk controller and a second cache. The method includes: receiving a read request, wherein the read request comprises an identifier of a to-be-read logical block; sending a first command to a hard disk controller of the hard disk when the first cache does not comprise data stored in the to-be-read logical block, wherein the first command is used to instruct the hard disk controller of the hard disk to return the data of the to-be-read logical block from the second cache of the hard disk; outputting the returned data, and caching the returned data in the first cache; and controlling the hard disk controller of the first hard disk to delete the returned data stored in the second cache.

Claim (Index 6):
The method according to  claim 1 , further comprising:\n determining, by the RAID controller, an identifier of a pre-read logical block in the first hard disk according to the identifier of the to-be-read logical block; and sending, by the RAID controller, a third command to the hard disk controller of the hard disk, wherein the third command is used to instruct the hard disk controller of the hard disk to obtain data stored in the pre-read logical block, and cache the obtained data in the second cache.
