RAM latency question

I have come to understand that the smaller(lesser) your latency, the faster things are going which is good, obviously. So CAS 2.0 seems the be about the best RAM right now, but when I look at RAM on Newegg.com and tier them according to price, the most expensive(and I am assuming best quality) Ram has larger latencies, like 7-7-7-20 and even 9-9-9-27. I don't get it.

Someone will know the answer, thanks.
 
the bigger the capacity, the larger the latenncy. This is natural, it takes more time to search for a piece of data in 2gs of ram then in 512 ram. So this is why.

Huh? The capacity has hardly anything to do with the latency...

@JLV2k5 - The most expensive RAM modules are probably DDR3 or ECC ram, and I would think these are what you were looking at. DDR3 as a fairly new technology naturally has high latencies, just like DDR2 when it was first introduced. ECC ram, which is for servers&stuff, is very reliable but expensive and come with high latencies as well (due to this error-correction whatnot which takes a bit of time).
