The Samsung 840 is the budget version of the 840 Pro, the main difference between the hardware on the two drives is the type of flash memory used. The cheaper 840 uses TLC NAND which is cheaper than the MLC found in the Pro version of this drive. The performance hit as a result of the cheaper TLC memory is approximately 30%. The 840 delvers both average real world speeds (435 MB/s) and average enterprise speeds (AS-SSD Total Score 920). The relative weak spots in this drives performance profile are its write ability, where it scores just 254 MB/s in the sequential write test. The upside to the lost performance over the Pro version is a significant reduction in price which leaves this drive an average value for money proposition at its current price of £135. There are, however, better value drives to be had elsewhere including Samsungs own newly released EVO which effectively supersedes the 840. [Aug '13SSDrivePro]
The Kingston HyperX Fury has the same controller as its HyperX 3K sibling; the only difference between the two drives is the use of cheaper Micron 20nm NAND in the newer Fury. Comparing the performance differences between the HyperX Fury and 3K shows that the newer 20nm NAND results in an effective performance decrease of around 30% for a price saving of just 12%. The Fury was never aimed at the high performance sector of the market but given the known compressible performance weaknesses of its Sandforce 2281 controller and its relatively non-budget price tag, the 120GB Fury will struggle to find rational takers in today's market. There are far better value alternatives available for just a few more dollars. [Sep '14SSDrivePro]
