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.
RAID works by spreading the data over several disks. Two of the terms often used in this context are stripe size and chunk size. The chunk size is the smallest data block that is written to a single disk of the array. The stripe size is the size of a block of data that will be spread over all disks.
