No idea, but i can honestly tell you i am massively impressed with this new seagate firecuda. The 8gb's of flash storage is more than enough, as it speeds up the things that need to be. My desktop is usable faster than my HTPC is that has an SSD in it. Obviously full on flash storage is superior in pretty much every way, but the prices are simply way too high still to be seeing HDD's going away. Stopgap is a good term here, but its going to be a lot longer of a time period than most think. Intel knows this and that is why they developed this optane stuff.
