this feature is called readyboost and its really intelligent.. it keeps a cache of your virtual memory and really speeds things up and gives your hard drive a break. when you click on something there is an index that tells the hard drive where to go to get that file... with readyboost that index is on the sd card.. that way your hard drive does less work.. and the system is much snappier... newer pc laptops will have flash built in to the hard drive which will make startup very quick...
one more point.. windows has about a 3 gig page file for 1.5 gb of ram... when i had a macbook pro it was more like 7 or 11 gigs!!!! whats up with that? google about the "mach" kernel which osx is based on.. its VERY inefficient with ram and page files...this explains why OSX is UNUSABLE with 512mb or ram.... its also the main reason OSX is not used for webservers... there is alot of talk that apple will be dropping the mach kernel... they fired the guy who was its main cheerleader... rumours? another major change to the os?
paaahhlleease.. with osx's crappy ram performance versus vista's new readyboost feature .... which would you choose?
Just a few clarifications -
It's perfectly possible to put your swap file (Virtual Memory) on a flash drive in OS X, and yeah, it will speed things up. I hate how Microsoft are calling this a new feature as it's really quite simple... I can put my swap file on a network drive if I want to, and I could on any UNIX, and I've been able to since the mid-80's if not before.
One thing though, using your sd card to keep your swap file on will probably kill it quite quickly as that is A LOT of writes something that flash memory doesn't like.
I personally do not at all find OS X unusable with 512MB of RAM. Maybe I'm not pushing it hard enough, though.
And Avie (Mach's "Cheerleader"), former Vice President of Software Engineering att Apple, was not fired, he just left. He's been with Apple since it was called NeXT:) and wanted to do something else after having overseen 5 odd very successful releases of MacOS.
And Mach is not OS X's kernel. OS X's kernel is called XNU and it is a hybrid of Mach and FreeBSD's kernel. But it is arguably a bit shit, granted.
