Abstract: Implementations disclosed herein provide a method comprising comparing high-latency data sectors of a storage band, the high-latency data sectors having latency above a predetermined threshold, with target sectors for storing new data to determine one or more of the high-latency data sectors that may be skipped during retrieval of at-rest data from the storage band.

Abstract: Systems and methods are disclosed for performing band rewrites on shingled storage media based on error scan counts. In one embodiment, a device may comprise a data storage medium including a first band and a processor. The first band may include a plurality of tracks storing data in a shingled manner where a first track at least partially overlaps a second track. The processor may be configured to receive a write command directed to the first band, increment a first rewrite count of the first band based on the write command, and when the first rewrite count exceeds a first rewrite threshold, perform a read-modify-write (RMW) operation for all of the first band. In some embodiments, a device may maintain write counts for sections of a band, and perform RMW operations on less than all of the band.

Abstract: In a shingled magnetic recording system, LBA can be dynamically allocated to an un-shingled media partition (UMP) based on a usage metric. In one implementation, the usage metric depends upon the frequency of writes to storage region and/or upon how recently the storage location has been written to. Data corresponding to one or more LBA ranges within a shingled data region may be rewritten to a storage region within a UMP on the disk.
Abstract translation: 在一个铺垫的磁记录系统中,可以根据使用度量动态地将LBA动态地分配给未绑定的媒体分区(UMP)。 在一个实现中,使用度量取决于对存储区域的写入频率和/或最近存储位置被写入的频率。 对应于带有加亮数据区域内的一个或多个LBA范围的数据可以重写到盘上的UMP内的存储区域。
