Ever since SSDs first hit the consumer market, performance enthusiasts have had to juggle between high speed storage and disk space. Even today, buying a terabyte of SSD capacity is nearly an order of magnitude more expensive than a 1TB hard drive. Conventional wisdom has predicted that this will remain the case indefinitely, which is why it was surprising to see SanDisk announce an upcoming 4TB SSD. Granted, this is an enterprise drive, intended as a replacement for SAS HDDs — but many consumer technologies start off in the enterprise before hitting dramatically better price points in the mainstream. Could this signal a sea change in SSD capacities? Will SSDs eventually provide more storage than HDDs?
