The storage industry is shifting from 3Gb/s devices to the new 6Gb/s specification which has been a boon to manufacturers as new devices are needed to handle the new, faster devices that 6Gb/s enables. The 3Gb/s specification reigned for roughly five years which allowed user speeds up to 300 MB/s. With the advent of “disruptive” technologies like SSD devices, the limits of 3Gb/s have been pushed back faster than expected. Now with devices that are able to saturate the specification, 6Gb/s and its 600 MB/s speeds could not have been integrated in a more timely and appropriate manner. As an added bonus, the specification is backwards compatible with the existing 3Gb/s specification, allowing users to upgrade the different portions of their storage subsystems at their leisure. With SAS offering compatibility with SATA 6Gb/s as well, the choice to upgrade is definitely one that will afford many levels of storage devices to be used.
