A new wave of high speed storage interfaces is on the way offering improved storage I/O performance. To see the expected performance improvement you have to make sure every link in the I//O chain is ready. The storage devices are ready for it thanks to technologies like wide striping and solid state disk. Fibre on the drive may be waining and 6Gb/s SAS/SATA seem like they will be the primary drive interface for the future. There may be a few demands for fibre in legacy enterprise storage systems until they can move over to SAS.”]
