Abstract
Aspects of a storage device for providing superior sustained sequential write (SSW) performance are disclosed. A controller on the storage device allocates buffer space in the host memory buffers (HMBs) on the host device for storage of relocation data, i.e., data to be folded or compacted. The controller or a hardware element therein can therefore allocate local SRAM (including TRAM) for use in accommodating incoming host writes. The increased SRAM allocation of relocation data without an attendant increase in cost or size to the storage device enables the storage device to perform operations in parallel and substantially increase SSW performance metrics.
