New i5 3570k build need help choosing hard drive

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.

  1. Best answer
    get this or the caviar balck

    either one wont do you wrong. the momentus is a laptop drive.

    the momentus xt is a hybrid drive. yu do get some increase in speed, but it only has its advantage if you do the same tasks frequently. if you are to get the hybrid, get the 750gb version. it has more nand.
  2. Ok great thanks!
