Even though the two drives were quite close in benchmark performance, the Samsung drive had a small edge in every single test we ran. In sequential read and write tests the 840 showed us the fastest scores we’ve ever seen, with its closest competitor being both the Neutron GTX and the SandForce Patriot Pyro SE. In our 32-command-queue tests, the Samsung also trumped the Neutron GTX but lost big-time to the SandForce-based drives, as they are simply head and shoulders above everyone right now. These were the only tests in which the Samsung failed to set a new record.
