    I was searching for memory for my 2012 iMac (delivery last week Dec) on Frys.com. In the Corsair memory product page, there's a video which talks about setting up a Ram Disk and how it is waaay faster than an SSD because memory bus speeds are multiple time faster than sata speeds. Does anyone know if this is possible in the Mac world?

    Another question - anyone used Corsair memory? The one listed in the link below? It is less expensive than Crucial or OWC..

    some things i found googleing for "ram disk mac"



    im using a ram disk on my windows pc. it's pretty nice because it spares the SSD from a lot of writing and reading. but remember: you only put temp files on the ram disk and i actually don't know if mac uses that many temp files???

    and no the ram won't fit! yours is a 240 pin ram and the imac has 204 pin so dim laptop memory

    Very, very useful zhandri. Thank you... Now I know why I prowl around these forums so much! :p

    The first link in your post is in German - but the second link gave me all the info I needed. And thanks for the info on non-compatibility of that specific product.
