Dynamic Write Acceleration

Dynamic Write Acceleration

Dynamic write acceleration optimizes SSD performance for typical client-computing environments, where WRITE operations tend to occur in bursts of commands with idle time between these bursts.

Capacity for accelerated performance is derived from the adaptive usage of the SSD's native

NAND array, without sacrificing user-addressable storage. Recent advances in Micron

NAND technology enable the SSD firmware to achieve acceleration through on the fly mode switching between SLC and TLC modes to create a high-speed SLC pool that changes in size and location with usage conditions.

During periods of idle time between write bursts, the drive may free additional capacity for accelerated write performance. The amount of accelerated capacity recovered during idle time depends on the portion of logical addresses that contain user data and other runtime parameters. In applications that do not provide sufficient idle time, the device may need to perform SLC-to-TLC data migration during host activity.

Under accelerated operation, write performance may be significantly higher than nonaccelerated operations. Power consumption per-byte written is lower during accelerated operation, which may reduce overall power consumption and heat production.
