siliconbits writes: Seagate has smashed the storage capacity barrier again today by launching an external hard disk drive with a 4TB capacity, one year after having launched the world's first 3TB drive. The GoFlex 4TB uses four 1TB 3.5-inch platters with an areal density of 625Gb per square inch, spins at 5400RPM and has 32GB cache (rather than 64GB). That said, even with a rather low spinning speed, it should, in theory, outperform faster spinning hard disk drives from 2007 or 2008.

sole test of the validity of any idea is experiment."
