In fact, if SSDs were about as fast as RAM, we wouldn't need RAM at all!
Just in case anyone was curious, I looked into this recently, assuming 7-8GB/s was pretty darn fast, but dual channel DDR2 RAM was doing such speeds in 2002. So a high end SSD is about as fast as 20 year old memory, if you ignore latency.
I don't know what people are reading into my comment. I said _if_ SSD speeds were comparable to RAM, RAM wouldn't be needed. The reason we need it is precisely because disk is slower and cheaper.
