Late last week SanDisk launched its Optimus MAX Serial Attached SCSI (SAS) solid state drive (SSD) with a capacity of 4TB. This was heralded as an industry first and as the "first true replacement for Data Centre HDDs delivering SAS features and performance," on offer at a "breakthrough price point".

Right now it's quite common for computer users to employ a combination of SSD and HDD drives as the cost per GB of HDDs is so much better and we all need quite a bit of backup storage for ever larger games and high resolution media files. However with the kind of storage capacity growth and cost per GB decline forecast by SanDisk we could be seeing the majority of users going 100 per cent solid state in a few years. For now this 4TB Optimus MAX drive represents an enterprise solution.
