For our today’s SSD test session we use a unified test system built on an Intel H77 based mainboard, which features two SATA 6 Gbit/s ports. We will use these ports to connect the tested SSDs.
As for the today’s testing participants, it is obvious that Samsung 840 Pro 256 GB and Samsung 840 250 GB SSDs must be compared against the most current offering from other vendors. Therefore, you will see on the diagrams the performance numbers for versatile popular products based on SandForce, Marvell, LAMD and Indilinx controllers, as well as the representatives of Samsung’s previous SSD generation. The LSI SF-2281 is represented by the today’s fastest product based on it - Intel SSD 520, as well as a typical solid state drive - Corsair Force GS. LAMD LM87800 controller will be tested in Corsair Neutron GTX and Corsair Neutron SSDs. OCZ Vertex 4 and OCZ Vector defended the honor of the Indilinx Everest 2 and Indilinx Barefoot 3 controllers. Marvel platform was brought in by Plextor M5S on Marvell 9174 controller, and Plextor M5 Pro based on a more up-to-date Marvell 9187 controller. And of course, we couldn’t leave out the previous generation Samsung 830 SSD on the MCX controller. All above mentioned SSDs use exclusively synchronous MLC flash memory. Corsair Neutron, Intel SSD 520, OCZ Vertex 4, OCZ Vector and Plextor M5S are built with 25 nm memory from IMFT consortium with ONFI-interface. Corsair Force GS, Corsair Neutron GTX and Plextor M5 Pro use Toggle Mode MLC NAND manufactured by Toshiba using 2x nm or 19 nm production process. As for Samsung SSDs, I would like to remind you that they use their own memory: it used to be 27 nm Toggle Mode MLC NAND, but now the new drives are designed with 21 nm MLC and TLC NAND with Toggle Mode 2.0 interface. We did our best to ensure that all testing participants came in the closest storage capacity, to ensure fairness of the comparison.
