Fusion-io, the company famous for producing the world’s fastest and most expensive SSD solution, is back again with another blazing fast innovation. This time, we’re drooling over the ioDrive Duo, which is hailed as the fastest and most innovative SSD this planet has ever seen. Per usual, the server-based PCI Express SSD offering is aimed at enterprises who can and will pay more for vast quantities of lightning fast storage space. How fast, you ask? Oh, just 1.5 gigabytes per second of sustained throughput.
