Publication number: 20240160563Abstract: Aspects of a storage device are provided including improved victim zone selection for zone-based GC in ZNS. The storage device includes a NVM having first, second, and third blocks, and a controller. The controller creates a first superblock including the first blocks, a second superblock including the second blocks, and a third superblock including the third blocks. The controller determines whether a quantity of data overwrites associated with a first zone in the first superblock is larger than a quantity of data overwrites associated with a second zone in the first superblock. From the determination, the controller performs GC for the first zone prior to GC for the second zone, in which data overwrites associated with the first zone in the first superblock and sequential data associated with the first zone in the third superblock are relocated to the second superblock. Thus, storage device performance is improved and WAF reduced.Type: ApplicationFiled: July 7, 2023Publication date: May 16, 2024Inventors: Navin KOCHAR, Sampath Kumar RAJA MURTHY, Suhaib Mohammed ADHONI

Publication number: 20240160562Abstract: Aspects of a storage device are provided including zone-based GC in a ZNS. The storage device includes a NVM and a controller. The NVM includes first blocks, second blocks, and third blocks. The controller creates a first superblock including the first blocks, a second superblock including the second blocks, and a third superblock including the third blocks. The controller allocates a first sub-drive including the first superblock for storing data overwrites and a second sub-drive including the second and third superblocks for storing sequential data in the NVM. During GC for superblocks respectively including data for a specific zone, the controller relocates written data for this zone from the first and third superblocks to the second superblock while refraining from relocating data associated with other zones from the first superblock to the second superblock. As a result, storage device cost, overprovisioning, and WAF may be reduced.Type: ApplicationFiled: July 7, 2023Publication date: May 16, 2024Inventors: Aakar DEORA, Navin Kochar, Sampath Kumar Raja Murthy, Gursimran Kashyap
