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).
