Enterprises aren’t into solid state yet. The capacities are way too low.
Enterprise customers are very much using SSD. We have a ton of it.
Ehh... that's SORT of true. The real prohibitive factor is cost. A 240 GB SAS SSD is twice the price of a 1 TB SAS HDD. However, if you look at companies like Simplivity, who are creating insane turnkey storage systems in a 2U form factor, you're going to see a massive effort to force the old-hand HDD adherents like EMC and Dell to go more toward SSD for speed.
You have to have a massive enterprise budget to afford an EMC disk shelf with SSDs. Hell, even tier 1 storage is around $15/Gb, and that's usually spinning disk with large amounts of cache. Using SSDs in the enterprise is best for virtualization, IMO. Fast provisioning, fast boot, and you don't have a disk bottleneck when you're running on a UCS chassis or an HP BladeCenter.
Syracuse University runs a large data center, most of it the standard HDDs. They do have a couple of racks of SSDs running as a cache for the most frequently accessed data. It was a pretty impressive setup.
