Abstract
A method for restricting write cycles to a storage device includes tracking a first count of a first set of writes to memory executed by a first subsystem of a computing device and, further, determining that the first count meets a write threshold of the first subsystem. The method includes determining that blocking criteria are met by the first subsystem based on the first count exceeding the write threshold of the first subsystem and, further, determining that blocking criteria are not met by a second subsystem of the computing device. The method includes blocking the first set of writes from being synchronized to the storage device, based on the blocking criteria being met by the first subsystem, and synchronizing memory contents of the second subsystem to the storage device, based on the blocking criteria not being met by the second subsystem.
