Complete Device Level Validation of Solid State Flash Drives -- An Approach

This paper highlights the Device level testing of SATA SSD´s (Solid State Drives). Device level testing aims at testing the intrinsic functionality of the storage devices. Commands are issued to the SSD under test to validate the attributes such as methods of transfer, latest technology involved to structure the storage device functionality, performance and the adherence to the protocol (SATA protocol). Performance test validation is required for NAND flash components and is used to substantiate the data performance read/write claims. The types of testing at the device level are Conformal testing, Non Performance Command Testing and Performance Command Testing. This paper outlines the process involved in validating SSD´s (SATA).
