Do you never have your servers go down unexpectedly? I know I do for reasons that have nothing to do with my site or anything I've done. I've even had one go down because some guy in the server building did an oops! and disconnected us. I would rather have my servers optimized to run well and have the data stored on the drive than count on the servers never having any sort of problem.
Well, that is what the failsafe would be for so you benefit from the same security for data as with disk storage and also the speed benefit of memory storage.
And 3000x more speed for a big forum can make a huge difference, let alone in savings on hardware when you would use 64 gig ram (2000 USD) instead of a few extra servers (20k USD or more).
How much time would it cost to repopulate the memory tables from disk? Even if it costs 10 minutes for very big forums, why not having the server show a temporary maintainance message during that time. (64 gig data from a disk with 100MB/s speed would take about 10 minutes to do it)
The speed benefit would be so huge during the time the server remains online, I doubt any super expensive hardware setup will be able to beat it easily.
