EconolineCrush writes "SSDs hardly offer compelling value on the cost-per-gigabyte basis. But what if one considers performance per dollar? This article takes a closer look at the value proposition offered by today's most common SSDs, mixing raw performance data with each drive's cost, both per gigabyte and as a component of a complete system. A dozen SSD configurations are compared, and results from a collection of mechanical hard drives provide additional context. The data are laid out in detailed scatter plots clearly illustrating the most favorable intersections of price and performance, and you might be surprised to see just how well the SSDs fare versus traditional hard drives. A few of the SSDs offer much better value than their solid-state competitors, too."
