Solid-State Drives and Caching
Intel® High Performance Solid-State Drives
What is the difference between controllers with or without compression function?

Data compression is the process of encoding information so that fewer bits have to be stored on the drive. Data compression reduces write amplification, which can increase the endurance of a SSD.

The data compression engine in the Intel® Solid-State Drive (Intel® SSD) controller optimizes performance based on the data pattern of the workload.

These tables provide both compressible and incompressible Input/Output Operations per Second (IOPS), and sustained read and write bandwidth specification.
