Whats the difference?

Whats the difference between the two? A SATA 3.0Gb/s and a Serial ATA150? Is a 3.0 much faster? how much faster?

Well, by my calculations, 3 GB/s is 2x1.5GB/s.

So, like, uhhhh... double.

The bandwidth isn't the only difference between the SATA I and SATA II specification though. Lots of companies jumped the gun with NCQ-type technologies, but you should get better performance out of a SATA II drive in general. Raptors excluded, of course (gotta be careful of those Raptor fans, anyone who pays $2/gig is likely to defend their performance to the grave).

You get better performance out of newer drive due to newer design... going from 1.5 to 3.. is almost nothing... we went from ata/33 to ata/133 and see almost no improvement..

I was going to get a Raptor, but at $160 it didn't seem worth it. The reviews I read said that they were fast but not amazing fast? If I don't care about noise level, should I dish out the extra cash for a Raptor, or just get a SATAII? This would be mostly for gaming.

but Raptors show their performance benefits in benchmarks, while SATA3.0 does not. Raptors are viable in that if you need some more speed, you'll have to pay a little more for it than you should. but that's evident in almost every computer part.

SATAII is irrelevant to the home user.

NCQ is a handicap, the extra bandwidth of the 3.0gb/s isn't needed, in short no benifits. However it costs a matter of pennies more to make a SATAII controller than a SATA one, and since people get fooled by the marketing it's a matter of why not.

Newer drives are faster drives, but SATAII is irrelevant.

Raptors or faster HDs will mean that you load maps faster, saved games faster and will speed up stuff like ripping DVDs. It won't make any difference at all to your fps or the eyecandy you can use. I wouldn't bother getting a raptor untill you've already got a dual core CPU and 7900GTX/X1900XTX. (I speak as a proud owner of a 7800GT and raptor 74, good HD but not good value for money.
