Test System & Comparison Drives

Legit Reviews Storage Benchmark Test System

All tests were performed on a fresh and up-to-date install of Windows 8 Pro x64 with no other applications running while using AHCI mode set through the BIOS. Synthetic Benchmarks were run with the OS loaded on a 120GB Corsair Force SSD. In between every test, the test drive was secure erased using an instance of Samsung’s Magician toolbox. As such, all results should be indicative of optimal performance. All components were set to their default speeds and are listed below.

Comparison Drives And Other Models We Have Tested

Since there are so many SSDs out there now with different controllers, we started a reference table of which controllers are used by each drive to help you compare results. Different controllers definitely perform differently and each has various strengths and weaknesses. Like CPU’s, even identical drives will have variations in performance and part of that variance may be attributable to the NAND flash used. Since the tests of the drives listed have spanned different test benches and represent different interfaces, we have listed the most recent ones for easy reference.

 SSD MODEL CONTROLLER(S) TRIM? Interface
Sandisk Ultra Plus 256GB Marvell 88SS9175  Yes  SATA III
Corsair Neutron GTX 240GB LAMD LM87800 Yes SATA III
Intel 520 Series 240GB SandForce SF-2200 (SF-2281) Yes SATA III
OCZ Vector 256GB Indilinx Barefoot 3 Yes SATA III
Kingston SSDNow V300 120GB SandForce SF-2200 (SF-2281)  Yes SATA III
Samsung 830 Series 256GB Samsung S4LJ204X01-Y040 Yes SATA III

CrystalDiskMark 5.2.0 Readout:

For the Samsung 840 Pro 512GB drive, the readout on CrystalDiskInfo 5.2.0 shows that both NCQ and S.M.A.R.T. are enabled, as well as TRIM and the interface is confirmed at SATA III (6Gbps). This is a great free tool to see lots of detailed information about the drive such as the firmware version for which we are running the latest available at the time of testing DXM04B0Q. There was an initial firmware revision released that fixed a fatal bug but it only impacted those drives sent for review samples as the retail drives had this most current revision upon shipping. Score one for getting a late sample drive!
