    Abstract: A method in a storage device includes receiving from a host storage commands for execution in a non-volatile memory of the storage device. At least a subset of the storage commands are to be executed in accordance with an order-of-arrival in which the storage commands in the subset are received. The received storage commands are executed in the non-volatile memory in accordance with internal scheduling criteria of the storage device, which permit deviations from the order-of-arrival, but such that execution of the storage commands in the subset reflects the order-of-arrival to the host.

    Abstract translation: 存储装置中的方法包括从主机存储命令以在存储装置的非易失性存储器中执行。 存储命令的至少一个子集将根据接收到的子集中的存储命令的到达顺序被执行。 接收到的存储命令根据存储设备的内部调度标准在非易失性存储器中执行，这允许偏离到达顺序，但是使得子集中的存储命令的执行反映了 适合主机。

    Abstract: A method includes, in a non-volatile memory that includes multiple memory blocks, defining a redundancy zone that includes at least an old parity block, a new parity block and multiple active blocks of which one block is defined as an open block. Data is stored in the redundancy zone and the stored data is protected, such that new input data is stored in the open block, redundancy information for the active blocks including the open block is stored in the new parity block, and the redundancy information for the active blocks excluding the open block is stored in the old parity block. Upon filling the open block and the new parity block, an alternative block is assigned to serve as the open block and the new parity block is assigned to serve as the old parity block.

    Abstract: An apparatus includes a memory and a processor. The processor is configured to send to a storage device a request from an application to retrieve data from the storage device, so as to cause the data to be transferred from the storage device to the memory, to send to the application an acknowledgement that the requested data is available in the memory before the data has been fully transferred from the storage device to the memory, and, when the fetched data is ready in the memory, to provide the data to the application.

    Abstract: A method includes, in a storage device that stores data for a host in a memory, estimating an impact of an amount of free memory space in the memory on a storage performance of the storage device. The storage device sends to the host a notification that is indicative of the estimated impact.
