With carrying out a large sequential write, the SLC-based Samsung 840 EVO was still disappointing and even getting beaten out by hard drives.

The 32MB quad-threaded write test in the Threaded I/O Tester at least puts the Samsung SSD on par with the Kingston drive.

When carrying out random writes the Samsung SSD was at least now running faster than the Kingston drive.

Lastly with Compile Bench the Samsung SSD performance was right behind the other tested Serial ATA 3.0 solid-state drives. Overall though the Samsung 840 EVO performance wasn't as compelling as anticipated even when factoring in its TLC flash memory, especially given that at least in many of these synthetic workloads the Kingston SSDNow V300 SSD cost just $70 USD for a 120GB capacity rather than $90 for the Samsung 840 EVO. For those now turned on by the lower-cost, better-performing 120GB Kingston SSD you can find it at and by using our Amazon shopping links you support our site.

I will continue testing these drives though once they are in their commissioned daily-benchmarking test farm and see how the performance fairs with time under Linux. Stay tuned for future Phoronix articles with updated results as well as my Twitter feed for any questions.
