SSD drives have no spinning parts and so they are not limited by how fast a platter is spinning. Instead it is the bus speed (how fast you can push information through the wires) that limits throughput. RAID is a technology that combines multiple disks (the I stands for inexpensive, but truly that depends) to act like one disk. Depending on the type of RAID this can also improve performance because information can be read from or written to multiple drives simultaneously (in parallel).
So what if you took the fastest drives possible (SSD) and linked them using RAID in the fastest way possible?
Transfer speed: 2GB/sec. Consider a DVD R contains only a little more than twice that, so about 2.5 sec to read the equivalent of a DVD R.
Load all the Office apps in 0.5 seconds! That's a lot faster than I can load one of them.
Open everything in the start menu - 53 apps: 18 seconds.
