SATA Express - worth waiting for?

Yes, that's the question? It'll be 16Gbps compared to 6Gbps with SATA3 currently. But will it really matter for most people? I guess it's mostly during sequential read/write that the difference may be noticed. But what such use cases are common?

No. It'll probably be worth jumping on once it gets here, I'm sure, because we already have drives that can be limited in sequential performance by the SATA bus, but there's till room to improve in IOPS, in ways that won't benefit from SATA Express.

The most important use cases for SATA Express are SFF and portable computers. SATA controllers with their own physical drivers add some cost on the die, add some cost on the package, and add some cost on the board. Since most computers have spare PCI-e lanes, anyway, why not use those, instead, and just wrap the protocol inside PCI-e?
