2T drive is not that more expensive than 1T drive also, I use mysql

Initially I plan to buy the WD green drives:( I guess the performance
hit is for all >2T drives?

This is nice and affordable but it doesn't provide much computing
power for me do backtest the price data... I am considering building a
desktop with i7-2600k core(need to wait till the motherboard for it is
fixed).
Thanks!
Jim.
