But for a single drive, why bother with Thunderbolt and the extra costs?

The apparent access time of the array would be half that of a single drive.

The first three devices I tested had single drives inside.

It's very cool how a single drive can accommodate cartridges of all different capacities, present and future.

With digital technology each package of 10 films for this year's festival arrived on a single hard drive in a compact box.

This is similar to how a single physical hard drive can be partitioned into multiple virtual drives.

Each of them has a single 500-gig drive.

There should be room for two internal hard drives and a single optical drive.

If that single hard drive then fails, all data stored in the entire array is lost.

Storage space starts out at a respectable 320GB on a single 7,200rpm hard drive.
