Abstract
A storage system allocates single-level cell (SLC) blocks in its memory to act as a write buffer. A host sends the storage system a threshold indicating an amount of data that should be stored in the write buffer before the storage system flushes the write buffer to multi-level cell (MLC) blocks in the memory. Using this threshold can extend the amount of time that data is maintained in the write buffer, which can reduce the write-amplification factor and power consumption, as well as increase read performance of the data.
