Abstract
A method of controlling a storage device includes detecting a cumulative usage condition associated with the storage device, comparing the cumulative usage condition to a usage value, and adjusting the operation of the storage device based on the comparison. Another method of controlling a storage device includes detecting an operating condition associated with the storage device, comparing the operating condition to a warranty condition, and limiting the operation of the storage device to read-only operation based on the comparison.
Claims25
A method of controlling a storage device, the method comprises:
- detecting a cumulative usage condition associated with the storage device;
- comparing the cumulative usage condition to a usage value;
- adjusting the operation of the storage device based on the comparison, wherein the operation of the storage device comprises read and write operations, and wherein adjusting the operation of the storage device comprises slowing read or write operations by adding a delay to a data transfer operation;
- and wherein
- the cumulative usage condition includes cumulative power-on hours.
