WD SSHDWD, a Western Digital company is shipping what it asserts are the world's first ultra-slim 2.5-inch, 5 mm hard drives and solid state hybrid drives (SSHD), which are designed for integration into the slimmest devices and space-constrained computing environments. With 500 GB of storage capacity and models with high performance-enabling solid state hybrid drive technology, this slim product line helps to address the tradeoffs system designers often make between capacity, physical size and performance.  To battle user-induced stress, WD has designed what it asserts are key enablers to the 5 mm form factor: the 5-mm height with compact connector offers system designers a greater degree of chassis design freedom. This ultra-slim form factor reduces weight by up to 36 percent compared with a standard 9.5 mm drive, according to the company; desirable acoustics and shock –operation and non-operation shock specifications with 400 G and 1000G, respectively; edge card technology – the connector and board use cell phone miniaturization technology to maximize the mechanical sway space in the hard drive and ensure shock performance;  a new small form factor SFF-8784 edge connector which receives power from and interfaces with the host I/O bus via the SATA interface connector SFF-8784; StableTrac – the motor shaft is secured at both ends to reduce system-induced vibration and stabilize platters for accurate tracking during read and write operations; and a dual stage actuator.
