W/D NO S/S * CONTACT SNIA FOR SFF SPECIFICATIONS
This specification defines the terminology and physicalrequirements for the mating interface and physical characteristicsof the Micro SAS Connector System. It is designed to support highspeed serial signals and power. While designed specifically for thesmaller, 1.8 inch form factor drives, including solid state drives,it should not be considered as limited to those. Its use will begoverned by applicable industry standards, e.g. Serial AttachedSCSI (SAS).
In an effort to broaden the applications for storage devices, anad hoc industry group of companies representing system integrators,peripheral suppliers, and component suppliers decided to addressthe issues involved.
The SFF Committee was formed in August, 1990 and the firstworking document was introduced in January, 1991.

General description
The internal Micro SAS connector is designed to enableconnection of a slim 1.8 inch form factor HDD or SDD to the SASinterface.
The internal Micro SAS connector uses the same 1.27 millimeterpitch for both the signal and power segments as the Micro SATAconnector as defined in the Serial ATA Specification. In addition,it contains a second signal segment on 0.8 millimeter pitch similarto the SAS internal connector as defined in SFF 8482. It containsan optional pair of contacts opposite the primary signal contactgroup. This pair is for OEM use and the voltage must be at or below5 volts. Also included is the same pair of optional manufacturingcontacts as exists on the Micro SATA connector.
Care should be taken in the application of this drive so thatexcessive stress is not exerted on the drive or connector.Backplane configurations should pay particular attention so thatthe drive and connector are not damaged due to excessivemisalignment.
