Week 14: Muddy

This week’s lecture, I was a little confused on what RAID actually is. The lecture described it as multiple devices treated as if they were one. But what really is that?? So, I searched the web and did some research on RAID (redundant array of inexpensive disks). I found that the website Wikipedia provided the best information on this topic.

Raid is a technology that allows high levels of storage reliability from low-cost and less reliable PC through techniques of arranging the devices into arrays for redundancy. It is also used for computer data storage schemes that can divide and replicate data among multiple hard disk drives. So basically, this array distributes data across multiple disks and seen by the computer user and operating system as one single disk.
