Is RAID 0 good or bad for booting Windows?

I was looking at a forum and they said that RAID 0 increases access time and you want low access time when booting Windows because it is a bunch of small files in random orders. However, I've heard from my friend and other sources that it speeds up windows boot time. Which is true and why?

It doesn't increase access time.Access time will be limited to the slowest disk, if you have two of exactly the same disk, your access time for a particular sector will be exactly the same.In RAID 0, data is striped equally across both drives. Therefore, RAID 0 starts windows faster because you are reading from two drives at the same time (double throughput). You can gain anywhere from an 80-90% increase in drive bandwidth by using a 2 drive RAID 0 over a single drive.The only shortcoming of RAID 0 is that if one of your drives fails, all data on the array is lost. If you want to put 4 or 5 drives in RAID, RAID 5 would be a much better solution as it includes parity, and has a tolerance of one drive failure.

It's true and Excessive Mhz covered everything. I want to add that for RAID0 you must use identical drives. The more drives the faster but this also means the chance of a drive failing and crippling your OS also increases. I know someone who has four solid state drives in a RAID0 setup and can open OpenOffice in a few seconds.
