Think big and fast in 2011. Traditional mechanical hard drives will be available in 3-terabyte (TB) capacities and larger - and at prices that will be budget-friendly.
Speed freaks, though, will want to look at the upcoming crop of solid state drives (SSDs), which will take full advantage of the newest 6 gigabit per second (Gb/s) SATA drive connectivity standard to pump data through your PC at roughly twice the speed of today's widespread 3 Gb/s standard.
SSDs will continue to command a price premium in 2011, but increasing capacities overall will bring down prices on the units that are currently the costliest. For those who have been waiting for SSDs to get big enough to be interesting, expect 600 gigabyte (GB) drives to appear early in the year.
