Abstract
A technique manages data in a flash memory drive which includes single-level cell (SLC) flash memory and multi-level cell (MLC) flash memory. The technique involves performing, within the flash memory drive, data placement operations on data which has been written to the flash memory drive. The technique further involves, based on the data placement operations, storing hot data in the SLC flash memory. The technique further involves, based on the data placement operations, storing cold data in the MLC flash memory, the hot data being accessed more frequently than the cold data. Such hot data and cold data can be distinguished based on access frequency.
