Abstract:
Systems and methods for allocation of overprovisioned blocks for minimizing write amplification in solid state drives are disclosed. An example system comprises: a plurality of memory devices and a controller operatively coupled to the memory devices, the controller configured to: determine a first value of a data stream attribute associated with a first data stream and a second value of the data stream attribute associated with a second data stream; determine, based on the first value and the second value, a first overprovisioning factor associated with the first data stream and a second overprovisioning factor associated with the second data stream; and allocate, based on the first overprovisioning factor and the second overprovisioning factor, a first plurality of overprovisioned blocks to the first data stream and a second plurality of overprovisioned blocks to the second data stream.

Claim (Index 17):
A computer-readable non-transitory storage medium comprising executable instructions that, when executed by a processor, cause the processor to:\n determine a first value of a data stream attribute associated with a first data stream and a second value of the data stream attribute associated with a second data stream; determine, based on the first value and the second value, a first overprovisioning factor associated with the first data stream and a second overprovisioning factor associated with the second data stream, wherein an expected data invalidation rate of the first data stream exceeds an expected data invalidation rate of the second data stream, and wherein the first overprovisioning factor is less than the second overprovisioning factor; and allocate, based on the first overprovisioning factor and the second overprovisioning factor, a first plurality of overprovisioned blocks to the first data stream and a second plurality of overprovisioned blocks to the second data stream.
