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 MLC 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 dur-
ing 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-MLC data migration during host activity.
Under accelerated operation, write performance may be up to 2.8 times higher than
non-accelerated operations. Power consumption per-byte written is lower during accel-
erated operation, which may reduce overall power consumption and heat production.
The following table shows the form factors and capacities that feature dynamic write
acceleration.
