Okay I understand the OP's post and to be honest it is no less than expected eg the overheads of running in raid with ssd slows down windows boot time since the randon access speed is the most important, not sequential read/writes but is that why people buy ssd's? I suspect not.
More important to people is how they perform in windows when booted up. I would live with a couple of seconds slower boot time if in windows it was generally faster.
Also a lot of people buy two ssd drives in raid because they can't afford a bigger drive and a single drive is too small for their needs.
Agreed completely. Would also like to add, that yes it may be a few seconds slower to boot, but its still a hell of a lot faster than HDD.
