A hard drive enclosure with functionality of quick-release, is for application in a host computer, and comprises: an accommodating unit, a plurality of removable units, a connection inter face module, and a connection module. Wherein the accommodating unit has an accommodating space and a receiving opening. And the plurality of removable units is inserted into the accommodating space through the receiving opening, and each of the plurality of removable units carries with a storage device. In the present invention, according to particular design of electrical connectors constituted by printed circuit board assembly, so as to improve insufficient space for electrical routing. In other words, the hard drive enclosure of the present invention includes advantages of decreasing assembly time and low production cost.

An apparatus with a housing which stores a plurality of data storage magazines where each data storage magazine includes a plurality of data storage devices. The housing includes a movable carriage configured to selectively couple a set of data storage devices held by a particular data storage magazine to a host device. The housing also includes a physical locking mechanism configured to selectively prevent data storage devices from coupling to the host device.

The housing includes a movable carriage, the movable carriage configured to selectively couple a set of data storage devices held by a particular data storage magazine to a host device. The housing also includes a motor configured to move the movable carriage within the housing to enable the movable carriage to communicatively couple the set of data storage devices held by the particular data storage magazine to the host device.

A hard drive backplane has a plurality of ventilation holes, and the expansion cavity muffler is mounted in the ventilation holes of the hard drive backplane. The expansion cavity muffler includes at least one expansion cavity and at least one connecting pipe in communication in a first direction. The connecting pipe at one end of the expansion cavity muffler facing toward the hard drive backplane is fixedly mounted in the ventilation hole such that the expansion cavity muffler is in communication with the ventilation hole. An area of a cross-section that is of each expansion cavity and that is perpendicular to the first direction is larger than an area of a cross-section that is of the connecting pipe adjacent to the expansion cavity and that is perpendicular to the first direction. The first direction is perpendicular to a surface of the hard drive backplane.

A system including an analog block and a digital block. The analog block and the digital block are arranged on a package. The package includes a first ground coupled to the analog block and a second ground coupled to the digital block. The second ground is physically separate from the first ground. The package also includes a noise-mitigation stitching connector that has a first end connected to the first ground and a second end connected to the second ground.

A server box embodiment is disclosed that generally comprises an array of dummy HDDs that share a common set of universal disk drive components in a master components module, or power module. Each dummy HDDs is constructed without expensive onboard chipsets that control the normal functionality of a standard HDD. By sharing expensive chipsets in a master components module (power module) money can be saved in building and selling the dummy HDD server. Embodiments envision a power module possessing the needed chipset functionality that is missing in a dummy HDD. The power module can be made to move from dummy HDD to dummy HDD supplying the necessary chipset in a shared manner when data is being stored or retrieved for client or end-user.

According to one embodiment, a disk device includes a housing with a bottom wall, magnetic disks supported on a hub of a motor, a printed circuit board provided on an outer surface of the bottom wall, and a wiring board attached on the outer surface of the bottom wall. The bottom wall includes a recess formed in the outer surface, a step located on border between the outer surface and the recess, and through holes opened to the recess. The wiring board includes one end portion disposed in the recess and connection pads on the one end portion, connected to lead wires of a coil. An adhesive is filled into the recess and the through holes, and covers the one end and a solder joint and seals the through holes.

A controller and a rectangular parallelepiped power supply apparatus are coupled to a rear surface of a midplane, to which a plurality of storage media drives are coupled in a front surface of the midplane. A plurality of interface connectors arranged in a left-right direction are provided at a front end of a controller substrate. The rear surface of the midplane includes a plurality of connectors for controller, which are a plurality of connectors arranged in the left-right direction to which interface connectors of the controller are respectively coupled, and a connector for power supply, which are connectors to which a power supply apparatus set horizontally is coupled. A part of a row of the connectors for controller is present below the power supply apparatus coupled sideways to the connector for power supply.

An expansion bay for a computer system having a rotatable fastening mechanism is disclosed. The expansion bay includes a bay housing having two facing side walls, a front open end and a bottom panel. A front tab and a rear tab extend from the interior of one of the side walls. A tray supporting an expansion component has a guide block with a threaded aperture. The tray may be positioned between an open position and a closed position. The rotatable fastener mechanism moves the tray into and out of the bay housing. A rod is inserted through apertures of the first tab and the second tab, allowing free rotation of the rod. The rod includes a threaded exterior section to rotationally engage the threaded aperture of the guide block. A knob is attached to an end of the rod to allow a user to rotate the rod and move the tray.
