Write amplification sand force ssd controller

This unique capability greatly simplifies SSD designs and helps to significantly reduce development and manufacturing costs for SSD makers. Exclusive SandForce controller data reduction technology combines several techniques to extend NAND flash memory life as flash geometries shrink and trend toward lower reliability. This technology extends flash memory life and significantly improves data integrity by implementing a flash-optimised low-density parity-check LDPC code that combines hard-decision, soft-decision and digital signal processing DSP together with unique adaptive error correction code rates. This enables SSD manufacturers to deliver enterprise-class product life and data integrity, even when using less expensive flash memory.
