Im looking to buy a new hard drive for my gaming rig and looking at various benchmarks it seems that some lower capacity hard drives have a higher average/max throughput but much slower access times than their higher capacity counterparts.

Seagate Barracuda 7200.11 320gb = 99.2 MB/s Avg Read throughput
Seagate Barracuda 7200.11 750gb = 82.3 MB/s Avg Read throughput - almost 25% slower

But the Random Access Time for the 320gb = 17.10ms
For the 750gb = 12.20ms - almost 50% faster

I realize that once you get to 1TB and bigger hard drives that you get the best of both worlds, but 1TB is really overkill for what i use.

What i would like to know is how much of an effect access time actually has on real world gaming performance. I mean were talking about miliseconds here ( 0.001 of a second!) . And also what would be more important, higher throughput or lower access time?

I don't have alot of money to spend on a new hdd and am mainly looking for bang for buck performance. Capacity isnt a concern, id rather a faster 320gb drive than a slower 750gb drive. 320gb will actually be more than enough, ive lasted the last 4 years with one 74gb Raptor :p i just delete games as i install new ones.

The Seagate 7200.11 320gb 'Cuda looks good, the only thing stopping me from buying it now is the relativley slow access time.
 
What Seagate model numbers are you looking at? Should be ST3_____AS, where the blank is filled in by some numbers.

I'm not 100% sure which models and geometry we're dealing with here.
 
Are you set on seagate drives? I haven't really heard much about seagate drives, but I've heard and seen and personally use the Western Digital Caviar series, 640AAKS/640AALS
 
Nah not set on Seagates, im open to any suggestions/recomendations. The Caviars were the other drives i was considering actually. I've been really happy with my Raptor so i wouldn't say no to buying another WD drive.
 
The 6400AAKS/AALS series are shown to be just as fast or faster then the older generation raptors, basically any raptor not a velociraptor. So I'd defintely look at them. I personally have a huge distaste to seagate due to their crappy RMA policy and dead drives. (I RMAed and drive and got a dead drive back, it was awesome, plus I had to pay shipping)
