Enterprsie disk storage
It's hard to believe the first EMC Symmetrix hard drive storage array, built for big corporate data, held far less than the typical USB thumb drive today. On the left is EMC's Symmetrix 1. It had four disk drives and held up to 2GB of capacity and had 256MB of memory.
On the right is today's 10th generation EMC Symmetrix VMAX. One cabinet holds 240, 3.5-in disk drives for up to 2 petabytes of data and has 128GB of memory; that's a million times more storage than the first array -- a little more than two decades earlier. The latest storage arrays also offer all flash memory storage with up to two million input/output operations per second (IOPS).
