System and method for adaptive optimization for performance in solid state drives based on read/write intensity

A computerized method of RAM cache optimization for a solid state drive (SSD) memory device comprising:

• executing instructions, via an SSD controller, of an SSD adaptive profiling engine for RAM cache optimization to determine whether SSD memory device operation is read intensive based on tracking read access counts to LBA segment addresses as recorded in LBA segment access counts;
• caching in a RAM a partial FTL table including look-up addresses corresponding to LBA segments in NAND flash memory when the SSD memory device operation is determined not to be read intensive;
• and
• establishing a data cache in RAM space unoccupied by the partial FTL table to enhance SSD memory device responsiveness.

An information handling system comprising:

• a solid state drive (SSD) memory device;
• an SSD controller executing instructions of an SSD adaptive profiling engine for random access memory (RAM) cache optimization;
• the SSD adaptive profiling engine determining whether the SSD memory device operation is write intensive or read intensive from assessment of stored LBA address read access counts and LBA address write access counts;
• a RAM cache to be used for caching purposes with the SSD memory device;
• the SSD controller caching a partial flash transition layer (FTL) table in RAM when the SSD memory device operation is determined to be write intensive and establishing a write cache in RAM space unoccupied by the partial FTL table;
• and
• the SSD controller caching a full FTL table in RAM when the SSD memory device operation is determined to be read intensive.
