Faster bits and bytes

Rather more prosaic than the technologies listed elsewhere in this article the internals of your PC are also being overhauled by the powers that be. There's a revision to the SATA standard out for disk drives, and USB 3.0 is appearing on motherboards to speed up the default peripheral connection.



They are big steps forward. SATA III doubles the bandwidth available to storage from a theoretical 3Gbps to 6Gbps, while on paper USB 3.0 is a ten-fold increase from 480Mbps to 4.8Gbps for cabled peripherals.
Motherboards sporting ports of both flavours are already available from most manufacturers. Although both technologies are much faster than their predecessors, neither is likely to have a huge impact on consumer PCs.
In the world of business where milliseconds are money, the upgrades may mean something, but for the likes of us, compatible drives and peripherals will be a while coming yet.
