I'm not immediatwly about to pull the trigger on a build, so likely I'm able to wait until late this year when there should be 3rd gen SSDs available, however, this question will almost certainly still stand.
I will certainly want my OS/apps on an SSD (I have an Intel G2 160G in that role in my current system), but I also want a fair chunk of app data on SSD too in my next system - in particular I want to host my VMs on one (which I don't have space to do in my current system).
Right now it is my intention to go entirely SSD (and keep archived bulk data I only need occassional access to on another machine, which has a large spindle drive). That means I'll need circa 100G+ for my OS+apps+systemy stuff, and then at least another 250G (ideally more) for app data (VMs, development source/objects etc.). I'm not sure whether it would be best to separate these onto two physical SSDs, or go for one big one. As I see it the pros and cons (of 2 SSDs reather than 1 big one) are:
Pro: Can stabilize the OS drive and still be able to switch out/upgrade the app drive independently (easily)
Pro: cheaper, at last unless the price-size ratio profile for SSDs changes soon
Pro (maybe?): With Windows 8 approaching and its use of storage pools, I could partition both physical drives and have mirrored partitions for key data. Partitioning would be necessary though, since the boot partition cannot be a storage pool, and because I won't want to take the capacity hit for mirroring everything
Con: one SSD would amortize the free space, probably leaving a higher free-space ratio which helps garbage collection performance
Opinions...?
