Often terms get thrown around the office that aren’t always apparently clear. When it comes to technology it’s hard to always be on top of the ball. However the term “RAID” is definitely one you should get to know. Gizmodo has done a great writeup on the what a RAID is and the various types of set ups. For the most part you only need to be concerned with RAID 0, RAID 1, and RAID 5 as these are the most common forms you will run into in the wild. Mirror, span, striped, parity, redundancy, just do a Google search and read up on your tech already.
Feeling a bit more adventurous? How about setting up your own RAID at home? Go to Lifehacker and just do it. Your spouse just might thank you when that crusty old hard drive decides to crap out and the RAID you set up saves the day. OR you can be really lazy and go to the local electronics store and pick up a little NAS box to do the job for you. Man, you really are lazy!
