Average Bench: 69.6% (676th of 1071)

Based on 41,998 user benchmarks.  Model: Samsung SSD 840 Series

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 '13 SSDrivePro]
