Abstract:
When a shingled magnetic recording (SMR) hard disk drive (HDD) performs additional SMR band copy and/or flush operations to ensure that data associated with logical bands that are adjacent or proximate in logical space are stored in physical locations in the SMR HDD that are proximate in physical space. As a result, efficient execution is ensured of read commands that span multiple logical bands of the SMR HDD.
