Raid10 can be a good compromise between raid5 and raid0 in terms of size. This configuration also allows you to have 1 and sometimes two drives fail and still maintain your volume. If you are like me and use your PC as a DVR, I have no real need for the extra speed. Raid5 is my choice because it gives me the most hard drive space while giving me at least one drive failure. If a drive does fail getting a next day air replacement from newegg will suffice. The odds that another drive will fail in those 24 hours are extremely low. If I want to be even more cautious, I can keep a hot spare in the array that could be merged into the array automatically.
