Best resource I've found for explanation of RAID setups in two years:
Wikipedia's (not to shabby) attempt:
Remember to note that RAID 0 is not really a true RAID array. It doesn't have data redundancy, as it simply stripes data across two drives to take advantage of reading from both drives concurrently (faster).
Go back through and re-read the whole thing once. There's a few typos (minor thing), and the tRP explanation under memory timings is chopped up somehow.
Looks good tho. Keep it coming, and you'll have to start chargin people for this.
