Samsung 850 Pro 1TB SSD Review
Test System & Comparison Drives
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 Parted Magic. 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.

CrystalDiskInfo 6.1.12 Readout:
For the Samsung 850 PRO, the readout on CrystalDiskInfo shows that both NCQ and S.M.A.R.T. are enabled, as well as TRIM. 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 is pre-production firmware and may be slightly different than what ships with the retail drives EXM01B6Q.
Let’s have a look at the performance with some synthetic benchmarks followed up by some real world tests.
