Every computer requires a storage device, so in this course you will explore different storage options and how they work, and discover various types of storage solutions for your computer. First, take a look at the Compact Disk (CD) storage medium and learn when to use it. Then examine the Digital Versatile Disk (DVD), and learn how to differentiate between the DVD and other storage types. Look at the Blu-ray disk format, another digital optical disk data storage form. Examine the features of Solid-State Drives or SSDs, a persistent memory storage type, and Magnetic Hard Drives, an electromechanical data storage device. Compare and contrast features of the two most common physical sizes for hard drives: 3.5 and 2.5 inch drives. Look into hybrid drives and their benefits, and the features of flash drives. Examine when to use hot swappable drives and learn the differences between Redundant Array of Independent Disks (RAID) 0, 1, 5, and 10. The concluding exercise deals with recognizing various storage solutions. This course can be used to help prepare for the 220-1001: CompTIA A+ certification exam.
