…. FusionIO does not provide any mirroring/stripping solutions and totally relies on OS tools there. So for Linux we have software RAID and LVM, I tried to followup on my post How many fsync / sec FusionIO can handle, and check what overhead we can expect using additional layers over FusionIO card. The card I…

Levi, In your cost calculation, if you’re mirroring Intel SSD for reliability, shouldn’t you also have 2 FusionIO in RAID 1 for an apple-to-apple comparison? In that case, the cost of FusionIO doubles: $14,000 for FusionIO @ 320GB MLC in RAID 1 $14,000 for FusionIO @ 160GB SLC in RAID 1
