Most SSDs are built using off-the-shelf parts, but the Samsung 840 Pro is different. It's made entirely by Samsung, and it combines 256GB of 22nm NAND with a proprietary three-core ARM Cortex-based MDX controller.

This in-house approach paid dividends in our benchmarks. Scores of 523MB/sec and 504MB/sec in AS SSD’s sequential read and write tests are exemplary, and it didn’t struggle with smaller files: its 4K file-read score of 37MB/sec is the best here, as is its 4K write result of 122MB/sec.

The 840 Pro impressed in the CrystalDiskMark tests, too, topping the tables in seven out of eight benchmarks. In our final test, ATTO Disk Benchmark, the Samsung continued to excel – its average read pace of 344MB/sec is the best here, and only the OCZ Vector’s 426MBs/sec beat its 410MB/sec write average.

It’s a great showing, and the five-year warranty is generous, although we’re a little miffed there’s no sign of a 2.5in to 3.5in bracket – something that’s included with the OCZ Vector.

The Samsung’s benchmark performance is lightning-quick, though, and its £180 inc VAT price works out at a reasonable 75p per gigabyte – great value when compared to the Corsair Performance Pro, which costs £1.15 per gigabyte. It’s a worthy A-List champion.
