What is it?

A small and portable external hard drive with a rugged design and multiple capacity options.

Good Points?

Weighing a paltry 40 grams (1.4 ounces) and measuring 9.6cm by 4.9cm (4in by 2in), the drive can easily be stored in even the tightest of trouser pockets.

An IP55 rating for water and dust resistance in addition to high shock tolerances allows usage in most environments and will benefit those who roam such as photographers.

Data accessibility is the primary function of any storage device and the Extreme Portable SSD does not disappoint with read speeds up to 550MB per second – that's the equivalent of around 14 music albums.

With capacities ranging from 250GB to 2TB there are ample options to choose from which means you won't have to shop around manufacturers for different needs and can stick with what you know works.

Bad points?

The higher capacity drives irregularly scale in price making them very expensive with the 2TB model costing £599.99 whereas the 250GB version comes in at less than £100.

Best for ...

Those who need the finesse of fast data access but don't want to compromise on robust design and portability. Field photographers will love the physical characteristics of small weight and mass. The various cables allow connectivity with older hardware too.

Avoid if ...

You are looking for storage to archive family holiday snaps as you would be better served with a cloud solution that has reliability at the cost of access speed.

Score: 9/10.
