Mechanisms for improving read command processing times in a solid-state drive (SSD) are provided, the mechanisms comprising: determining a workload type of an SSD; in response to determining that the workload type is a pure read workload type: determining at least one command size into which an original background write is to be split-up using at least one hardware processor; and splitting-up the background write into a plurality of split background writes, each having one of the determined at least one command size. In some embodiments, the at least one command size accounts for a page of the physical medium of the SSD. In some embodiments, the at least one command size includes at least two different sizes. In some embodiments, the mechanisms further comprise combining two or more split background writes. In some embodiments, the original background write is split-up before being placed in a channel queue.

System method for improving read command process times in solid-state drives (SSD) by having processor split-up background writes based on determined command size

A method includes determining a write amplification factor for a particular NAND-based memory device and a host coupled to the NAND-based memory device and includes calculating a bandwidth of the host. Based on the write amplification factor and the bandwidth of the host, a resource of the NAND-based memory device is allocated between the host and a garbage collection process of the NAND-based memory device.

Air compressor

Cap for air compressor

A compressor includes a housing, a drive shaft rotatably engaged in the housing, a stator attached to the housing, a pulley rotatably attached to the housing and rotatable relative to the housing, a front plate attached to the drive shaft and rotated in concert with the drive shaft, and a lock device includes a lock member attached to the drive shaft and rotated in concert with the drive shaft, and the lock member is secured to the front plate for anchoring and securing the front plate and the lock member and the drive shaft together. The drive shaft includes a non-circular section, and the lock member includes a non-circular bore engaged with the drive shaft for preventing the lock member from being rotated relative to the drive shaft.

Compressor internal control valve

Compressor front plate locking member

A compressor includes a cylinder housing having a number of pistons, a control chamber communicating with piston casings, a suction chamber and a discharge chamber communicating with the piston casings, a control valve includes a receptacle engaged in the cylinder housing, a valve member engaged in the receptacle for controlling the pressurized air to flow from the discharge chamber into the control chamber of the cylinder housing, and a valve element for controlling a bypass of the pressurized air through the receptacle. A bellow device is connected to actuate the sliding member internally, and a sliding member is slidably engaged in the control space of the receptacle, and to operate the valve element externally with a solenoid device.
