A method, apparatus, and system of a priority command queues for low latency solid state drives are disclosed. In one embodiment, a system of a storage system includes a command sorter to determine a target storage device for at least one of a solid state drive (SSD) command and a hard disk drive (HDD) command and to place the command in a SSD ready queue if the SSD command is targeted to a SSD storage device of the storage system and to place the HDD command to a HDD ready queue if the HDD command is targeted to an HDD storage device of the storage system, a SSD ready queue to queue the SSD command targeted to the SSD storage device, and a HDD ready queue to queue the HDD command targeted to the HDD storage device.

Priority command queues for low latency solid state drives

A method for selectively storing data identified by a software application in higher performance media may include executing control programming for an operating system and a software application hosted by the operating system. The software application assigns a first importance level to a first portion of data and a second importance level to a second portion of data. A first portion of data having the first importance level assigned by the software application is stored in a first storage medium at the instruction of the operating system. A second portion of data having the second importance level assigned by the software application is stored in a second storage medium at the instruction of the operating system. The second storage medium has at least one performance, reliability, or security characteristic different from the first storage medium.

Method and device for utilizing application-level prior knowledge for selectively storing data in higher performance media

A data storage system includes three or more storage devices, each associated with a unique data volume. A first one of the data storage devices at least has two or more data storage areas but can have more storage areas, which can be either data storage areas or parity storage areas. A second data storage device at least has two storage areas, one of which is a data storage area. A third data storage device at least has a parity storage area but can have more storage areas, which can be either data storage areas or parity storage areas. A first group of corresponding storage areas is defined by at least the data storage areas of the first and second storage devices and the parity storage area of the third storage device. A second group of corresponding storage areas is defined by at least the storage areas of the first and second storage devices. When a data segment is written to one of the data storage areas of a storage device, parity information can be updated using information read from one or more storage areas of the group of corresponding storage areas having the data storage area to which the data segment is written.
