Which hard drive should i get? And Whats the difference in "Cache" mean

[computerguy1234]

Hi, i am wondering what hard drive i should get. I don't want to spend to much money so i wan't like a more cheaper alternative like 60-80 dollars. I would prefer to get a cheaper priced Hard drive. I'll be using this hard drive for gaming and a little bit of video editing. These are the hard drives i have in mind:

WD caviar blue 500 gb 7200 rpm 16 mb cache: http://www.amazon.com/gp/product/B00...pf_rd_i=507846

WD caviar blue 1 tb 7200 rpm 64 mb cache:
http://www.amazon.com/WD-Blue-Deskto...dp_ob_title_ce

Whats the big different between the 16 mb cache and the 64 mb cache, will i see a big difference in performance and get the 1 tb 64 mb cache version for just 10 dollars more. And i dont really need 1 tb, i haven't even used up my whole 320 gb hard drive in the past 4 years.

The more cache the better.
With that said, would you consider a 128gb SSD as a primary and use your 320gb for storage? I beleive this setup is the faster and maybe the more practicle route. Pricing would be very close to the WD blue with the holliday deals most everywhere on SSD's.

twice the capacity, 4 times the cache for only 10 dollars more?

Would be a lot faster too as the platters will be more densely packed.

That 1TB Caviar Blue's access times are worrying:

And given that that 500GB Caviar Blue has a max transfer rate of 121MB/s, it probably has a 500GB platter instead of the new 1TB platters which push 200MB/s.
