In Pictures: Data storage -- then and now

As size of storage drives shrink, capacity increases - dramatically. Here is a look at how data storage it has changed over the last six decades.

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).

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
