Solid State Drives for Super Speed

摘要

Starting in 2009, IBM has been enabling IBM i to run with Solid State Drives (SSDs), and in 2010 the options will only get better. But first, let's take a look at SSDs in general. A traditional hard disk drive (HDD) has the familiar spinning magnetic disk with an arm that moves back and forth over the surface to read the data. Over the years, HDDs have gotten more capacity, faster, cheaper, and more efficient, and yet, they are absolutely trounced by SSDs when it comes to speed. In a 40-yard dash, think kitten vs. cheetah.
