Their naming convention is a bit confusing, but in fact the RamSan boxes 
are available in flash and RAM-based variants:

"The RamSan-630 offers 10 TB SLC Flash storage, 1,000,000 IOPS (10 GB/s) 
random sustained throughput, and just 500 watts power consumption."

I was referring to those. Of course, they may be more expensive than 
FusionIO. You get what you pay for (in this case).
