Recently, solid-state disks (SSDs) have arisen as an answer to the performance part of the cloud storage challenge, but there are deeper problems with scalability and synchronization that merely moving the same databases from hard disk to SSD doesn’t necessarily solve. That’s why a group at Stanford has a radical suggestion: Datacenters should just put everything in RAM.
These is a discussion on server technology so please do not apply desktop assumptions.

This is completely logical. Enterprise battery backup solutions could keep ramdisks active for days on end, not to mention having several locations with identical mirrors in RAM and rolling backups onto solid state media and conventional platters would make data reliability very robust. Given how inexpensive memory has become (even ECC memory is -relatively- inexpensive when purchased in bulk) and how easy it would be to develop a motherboard with enough memory slots to make up for the lack of capacity in a single module wouldn't be too outlandish. And these new memory 'cubes' could hold very promising for this application as well.
Unfortunately in the grand scheme of things, speeding up the cloud doesn't really speed much up at all for the end user as everything they do still has to be piped through an incredibly slow, overly latent connection, which in my opinion kills utilizing the cloud as much as say, Google, intends us to.

You don't even need a standard motherboard with enough memory slots. You can build RAMDrives which are just a controller connected to a bunch of DIMMs.

You are thinking about individual end users accessing a cloud. This is more for thousands to hundred of thousands of end users accesses a database simutaneously. The latency due to row-locks and coherency can impact users. This can have a major impact on HPC as these latencies add up. In addition by having RAM as the "standard" storage device, developers will know how storage will perform upfront without having to understand the exterme complexities of tiered storage.
