What will increase speed of shut down / boot? is 'instant' possible?

Hi,

I have to have many user accounts on my computers and somedays I have to switch between them many times.
My question is this:
When buying a new laptop what should I be looking for specifically to minimize the time it takes to log out of a user account and into another? (My computer gets slower and slower with each user account added).
IE will a continous increase of RAM result in a quicker log in / out process?
or would that be better facilitated with a faster processor?

Also, a friend told me about some kind of new harddrive with new moving parts which could make this process almost instant but I dont know the technical name for it. Any ideas?

Thanks in advance for any advice anybody can offer

Solid State Hard Drive, not a cheap one, a good one.

Will not be instant, maybe around 20 seconds.

again as long as the rest of the specs are good i.e. good prosseser enough ram to cope with everything the best thing to change is the hard drive alot of laptops only come with a 5400rpm hard drive upgrading to a 7200rpm hard drive will speed up chanaging between uses or even better a ssd especially if plugged into a sata 3 port. but do your reserch and get a good one.
