High-speed USB 3.0 flash drives are one of life's little treasures. Small enough to fit into your pocket, spacious enough to store masses of content, and fast enough not to keep you waiting: they're the sort of accessory that every regular PC user should have.

And as we've often said in the past, you needn't break the bank to step into the world of USB 3.0 devices. 32GB flash drives are readily available for under £20, and these cheap-and-cheerful solutions tend to be sufficient for most consumers. But the technology is moving forward on a couple of key fronts - both speed and capacity are on the up, while NAND flash prices have fallen - so high-end users may want to try something a little more advanced.

Corsair's Flash Voyager GS, available in 64GB (£70), 128GB (£90) and 256GB (£190) capacities, ought to fit the bill.
