Thank you for such an informative post. I've been involved in initial benchmarking of more standard enterprise SATA SSD's on a local RAID controller, and while the results are impressive, they're very limited to random workloads, on a very limited test set, they were limited to primarily 8KB and 64KB random reads and 8KB random writes (64KB random writes were merely double an equivalent 600GB 15K RAID 1 pair).

Question: Did you test degraded mode performance by, for instance, pulling one Fusion-IO card out (simulating total failure)?
