Functional speed difference between 4gb and 8gb Sandisk sticks?

[xist]

I'm in the market for a new MS and i'm curious as to whether there's a noticeable impact upon performance between the 4gb and 8gb Sandisk memory sticks. Logically it would make sense that the 8gb sticks are slower, and looking at the few Blackspeed results i can find it appears the performance index of the 8gb is significantly lower than that of the 4gb....but does it make any difference or have any noticeable effect on MS access at all? If so when is the 8gb stick a worse choice?

As far as i know the speeds are about equal. It is whether the stick is a non pro-duo, pro-duo, ultra 2 or whatever that has more impact on the transfer speed results.

The tests that come with blackspeed are a 32mb stick the psp comes with (non pro-duo), a Sony 1Gb (pro-duo) and an ultra 2 so they will be very differnt.

I may be completely wrong as i don't have an 8gb stick but i don't see posts where games are lagging or load slower on 8gb sticks or anything like that. I think you would need somebody with 2 similar sticks (say a 4 and an 8gb untra 2) to do some tests to be completely sure.

Yes that's what i was hoping for...it'd be nice to know if on blind testing the 8gb and 4gb could be differentiated on read speeds during memory intensive tasks...perhaps playing an iso of one of the GTA games or some other application that requires a quick stream of information? Is it likely that a Pepsi Challenge of this sort would yield a difference?

No one has both a 4gb and an 8gb stick for comparison?.....given that the performance index obtained via Blackspeed 2 appears, from my research, to average out at around 500 for the 4gb stick and 300 for the 8gb stick i was unsure if that was a noticeable decrease in performance.

I Have neither but I've only seen posts about lexar 4 & 8 gig sticks. Mainly the threads where about plugins not working with the lexars, it is a read speed problem not the sticks internal speed that is the issue as understand it. But again with exception of lexars you shouldn't notice any functional differences. Freeplay should be able to explain this better.

It's true that most lexars can't use plugins properly but i don't know the exact reason. My spare 512Mb lexar is fine with plugins and even works as a pandora sitck so i don't really care :D
