Abstract

A storage peripheral, such as disk drive, having a robust PCB connector configured in accordance with a SATA standard. The disk drive has a disk, a disk controller system, and a PCB for mounting the disk controller system, and a housing attached to the PCB. A first electrical contact arrangement in accordance with a SATA standard is connected to the PCB and is supported by a first blade connector. Both the first blade connector and the first electrical contact arrangement are enclosed by the housing. The housing further defines a cable connector receiving area around the first blade connector for the receipt of a cable connector. A pair of laterally-opposed guide arm receiving cavities are integrally formed with the housing and are disposed outside of the cable connector receiving area. The guide arm receiving cavities are adapted for the receipt of guide arms from a mating cable connector.
