SD port slow?

[gojensen]

I notice people using the SD port on the mini for things like pagefile and readyboost. Does anyone really notice any speed/performance enhancements this way?

I'm asking because last I tested the sd reader it's write/read speed was markedly slower than the already slow harddrive in the mini... and thus I'd think there would be a slow down if I moved important stuff there?

(Granted, seek/access time should be much quicker, but then again, cpu use is also higher while using the sd card rather than the harddrive)

Depends on your card mostly. Do you know what class it is? Also do you have a 2133, 1000 or 2140?

i use readyboost on my 4GB Extreme-III card (mini 2133 1.6gHz).
i don't see 'notable' improvement since i have 2gb of RAM.

with that said, i know that a few seconds saved here and there is much appreciated by me... that's why i bought the fastest card on the market (at the time).
