In reply to Bernard.

Yes, Fusion I/O cards still fit into the slow-write and garbage collection paradigm as the form factor drives. Internals are slightly different, but basically the same recommendations apply. We are looking to do some extensive testing with them later this year and will be able to make more detailed comments then.

Other "gotchas" for the internal-to-the-chassis based cards are backup (have to use server resources to accomplish), and localization (anyone besides this server has to access this server via TCP to get to them, and use the resources on this box (cpu/memory) to access).
