A spokesman for the company described the original piece of equipment, made 50 years ago, as "a monstrous piece of technology, weighing about one tonne and the size of a small walk-in freezer".
In contrast the latest version can be as small as 2.16-centimetres, weighing less than 10 grams – and it can store 800 times more data than its prototype.
"Without hard-disk drives, the space required to store the data for a small company of 25 people would require a storage area the size of a five-storey car park," said Martin Larsson, general manager of Toshiba Europe Storage Device Division.
