I am thinking about buying a SDHC card with Class 6 rate( 150X or say 6MB/s) to use it as a Readyboost/drive device for my T61 15.4". I won't need to use that mediacard reader frequently anyway. So question is:

1. does the media card reader on T61 surpport SDHC? Has anybody tried before?

2. How big capacity does VISTA surpport for ReadyBoost? I am wandering which card to buy, 4Gig or 8 Gig. I don't want to compnsate performance for price, but also hates to waste money on things I can't use.

I have surfed around microsoft and got no definit answer. So please kindly reply if you know it. Thanks.

the T61/p supports SDHC class 6.

the readyboost cache is limited to 4GB.

i've tested readyboost with both UDMA CF and SDHC cards and never noticed a difference regardless of system memory or card size.   installing more system memory gives the best performance for the money.
