Abstract: A storage device, and a method for operating a storage device. In some embodiments, the storage device includes storage media, and the method includes: determining, by the storage device, that the storage device is in a first fault state from which recovery is possible by power cycling the storage device or by formatting the storage media; determining, by the storage device, that the storage device is in a second fault state from which partial recovery is possible by operating the storage device with reduced performance, with reduced capacity, or in a read-only mode; and operating the storage device with reduced performance, with reduced capacity, or in the read-only mode.

Abstract: A storage system, and a method for operating a storage system. In some embodiments, the system includes a first storage device and a second storage device, and the method includes: determining that the first storage device is in a read-only state and that the second storage device is in a read-write state; performing a write operation, of a first stripe, to the storage system; performing a first read operation, of a second stripe, from the storage system; and performing a second read operation, of the first stripe, from the storage system, wherein: the performing of the write operation includes: writing a portion of the first stripe to the second storage device, and making an entry in a mapping table for the first stripe.
