How exactly do you have a diskless data storage centre?
Nowhere in the article did it say that Google was putting these SSDs in as local disks.
When I made my earlier comment about computers with no distinction between long term storage and working memory I was aware that it's been done in the past.
Maybe I should have clarified with imagine it for a users desktop PC.
Obviously reboots wouldn't solve crashes. Maybe some form of 'base configuration' would need to be stored in permanent infrequently accessed storage of some type. In the event of a crash some bios routine would be triggered to refresh the 'working' storage from this image, and up it comes. Then you have the issue of updating that image with installation and configuration data as a user doesn't want to have to reinstall programs everytime they've hard booted the machine. Of course you could also bork this base image, but then you can bork your OS installation at the moment, so nothing new there.
I think that where I'm going with this looks like some for of permanent storage (it could even be spinning bits of metal disk) with your base image on it, but sufficient working memory to take the entire image and hold it in a non-volatile medium. So with the exception of when you needed to do a hard boot you'd be working from and in your very fast non-volatile memory. An FS would still need to exist, one for the boot image and another 'virtual?' one for user data in the working memory (like a RAM disk I suppose).
Most of the time you'd have nearly 0 latency access, instant on programs and instant on and off PC, literally being able to just pull the plug out. Most of the performance issues that every day users perceive are in the opening of programs and the booting of the PC, most of the time of which is used transferring data from the HD to the RAM and processing the startup routines of said program, these would be completely eliminated.
