My new build includes:

i5 3570k
asrock z77 extreme 4
psu 750 corsair
8g ram
gtx 570

I am trying to choose between hard drives, but I need some advice on which one is the best overall:

Seagate Momentus XT 500 GB 2.5 Inch Solid State Hybrid Drive ST95005620AS going from 75.00-85.00

Western Digital Caviar Black WD7502AAEX 750GB 7200 RPM 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive 90.00 on newegg

Seagate Momentus ST9750420AS 750GB 7200 RPM 16MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive -Bare Drive 75.00 on newegg

Western Digital Caviar Green WD10EARX 1TB IntelliPower 64MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drive 79.00 on newegg

any input would be great. this computer will be used for some gaming, but overall I'm looking for speed and storage capacity.
