What is the cheapest way to get about 4 GB/s read speed for a computers primary disk drive? Minimum storage capacity of 120 GB. Is it a pci-e based ssd? Or raided conventional ssd's? The reason I ask is I was wondering how expensive it would be to symbolically link ones entire storage capacity (or at least most of it) to boot into a ram drive on startup and take "only" about 30 seconds to boot... Then be operating with read/write speeds up to 53,000 MB/s...
