Disk Array Storage: Performance Vs Capacity
As with other areas of IT, disk array storage has changed dramatically in recent years. Just over 20 years ago, personal computers came with huge spinning disks the size of dinner plates with capacities of just a few megabytes. That's right, megabytes. Today, a PC may have a smaller disk encased in a box about the size of a deck of playing cards with a capacity of several hundred gigabytes. Many modern laptops have shed the spinning disk in favor of solid state (flash) storage.
