A drive blank comprises a front member having a first end, a second end, a back face, and an aperture formed between the first end and the second end. The drive blank further has a first side member and a second side member each extending perpendicularly from the first end and the second end of the front member, respectively. The drive blank has a rear member extending parallel to the front member and between the first and second side members. A locking element is formed integral to the front member. The locking element comprises a looping portion having a first end and a second end and a push button formed at the second end of the looping portion and disposed in the aperture. The push button has a locking catch, releasably coupled to a latch element of a handle, to lock the handle in a closed position.

A spindle motor includes a base being a cast product as a part of a housing of a hard disk drive device. The base has a hole portion configured to accommodate a fastening member configured to fasten a member to be attached to the base. The hole portion is a blind hole extending in a depth direction from a surface of the base and having a tip surface formed flat.

A device includes an interposer card that includes a processor, such as a system on a chip (SoC), and memory devices. The interposer card mounts to a mass storage device and has a shape that corresponds to a size of an end of the mass storage device to which the interposer card is mounted. The SoC of the interposer card is configured to implement an individual server for the mass storage device to which the interposer card is mounted. In some embodiments, a data storage system includes multiple mass storage devices mounted in a chassis and coupled to one or more backplanes, wherein interposer cards are connected between the mass storage devices and the one or more backplanes.

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.

An information handling system, including a cover structure including a plurality of coupling members positioned on a surface of the cover structure, each of the coupling members defining a cavity; and a computing module having a perimeter and including a plurality of protruding members positioned on the perimeter, wherein each of a subset of the plurality of protruding members corresponds to a respective coupling member of the plurality of coupling members, wherein, when the computing module is coupled to the cover structure, each of subset of the plurality of protruding members is positioned with the cavity of the corresponding coupling member of the plurality of coupling members to maintain a positioning of the computing module with respect to the cover structure.
