Mounting apparatus for data storage device

A mounting apparatus for securing data storage devices includes a drive bracket, a number of first locking devices, a second locking device, and a spring. The drive bracket includes a first sidewall defining a pair of grooves for slidably receiving studs of the data storage devices. The first locking device is pivotally mounted on the first sidewall, the second locking device is movably attached to the drive bracket and moves corresponding to the first locking device. The spring connected the first sidewall and the second locking device. When the studs of the data storage device are slid into the grooves, one of the studs is slid into the cutout and sandwiched between the cutout and the end of said groove, thereby securing the data storage devices within the drive bracket.
