Will SSDs Change Storage Controllers?

I recently read a post on Henry Newman’s blog over at InfoStor questioning whether SSDs will change storage controllers, and it got me thinking...

For a potentially better approach, you might implement flash natively on the system, without any extra hardware and latency of a RAID controller—less hardware means better performance and fewer points of failure. Flash-based file systems can be designed specifically for the unique attributes of flash, such as WAFL, BtrFS or ZFS. Features like primary storage deduplication that were not achievable before without substantial compromises are now possible due to the speed of the underlying storage, which enables flash memory systems to deliver superior efficiency and performance. Other approaches would include using flash just for metadata, eg. Isilon OneFS.
