Abstract

A computer-implemented method of storing data on a storage device can receive an I/O request to read data from or write data to a data storage device. The data can be stored in special sectors as allocated sectors and regular sectors as a log-structured array (LSA). If the I/O request is to read data from the storage device, a determination can be made as to whether the data to be read is stored as a special sector, which can be read from the LSA, or as a regular sector, which can be can be read from the allocated sectors. If the I/O request is to write data to the storage device, a determination can be made as to whether the data to be written is stored as a special sector, to the LSA or as a regular sector, to the allocated sectors.
