I traditionally build systems with 2 drives - a smaller drive for the system and a larger drive for storage (and backups).
I'm currently specing out a new system, and I'm trying to decide between a board with a 32 gb msata drive used for Intel Rapid storage/smart response and one without. The price differential isn't that large, though enough that I want to see some benefit to it, and there's other features in play here. I'm interested mainly in the effects having a small caching SSD would have on a system.
Would a caching SSD have any benefits to a system thats already booting off a reasonably fast SSD? I'm not talking raw speed - would it save on writes for example? Does the caching system also help with secondary drives like the storage one I want to use?
