What is APES? AP Environmental Science (APES) is a year-long course that is the equivalent to a one semester college level Environmental Science course. Students will be expected to take the AP Environmental Science test in May 2016.
RAID is basically a group of disks, usually with one or both characteristics of parity and striping. Parity is redundancy of your blocks of data on the disks; striping allows the individual drive speeds and feeds to add up, giving you more performance than a single disk could provide.
The Clariion will write the Data out to the first disk in the RAID Group, and write the exact data to another disk in that RAID 1 Group. This is great in terms of data protection because if you were to lose the data disk, the mirror would have the exact copy of the data disk, allowing the user to access the disk.
