The evolution of computing is characterized by a vertiginous acceleration of speed and capacity. As we install sophisticated applications and make use of computers in more creative ways, storage needs are pushed even further. You can improve your disk performance by using a RAID-enabled desktop system running common OSS applications.
A typical hard drive is 100 times slower than memory while reading sequential blocks of data. If the data is scattered across the disk, the performance becomes even worse. Add multi-tasking to the equation, and the typical computer will start showing little progress on the screen. Fortunately, Linux makes Redundant Arrays of Independent Disks (RAID) accessible on the desktop, even for cost-conscious users.
