Shootouts

High-end PCIe SSD shootout: ADATA vs. Plextor vs. OCZ vs. Samsung

By Kenny Yeo - 4 Feb 2017

Test Setup & PCMark 8

Test Setup

The drives will be tested on our updated storage testbed using the Windows 10 operating system, which has the following specifications:

  • Intel Core i7-4770K (3.5GHz)
  • ASUS Z97-Deluxe/USB 3.1 (Intel Z97 chipset)
  • 2 x 4GB DDR3-1600 memory
  • MSI GeForce 8600 GTS
  • Windows 10 Pro

Here is the list of benchmarks used:

  • AS-SSD benchmark 1.8.5636.36856
  • CrystalDiskMark 5.0.2
  • PCMark 8 (Storage suite)
  • Atto Disk Benchmark 3.0.5
  • Iometer (version 2006.07.27)

As mentioned earlier, the Samsung has just released its own NVMe drivers for the SSD 960 Pro following feedback from earlier reviews (ourselves included) that the native Windows NVMe drivers weren’t quite up to the job. The results of the SSD 960 Pro that we are presenting here will be the updated set ecorded with Samsung’s own NVMe drivers.

We are keen to see how the Plextor M8Pe and ADATA XPG SX8000 will perform. We have already established that the Samsung SSD 960 Pro and OCZ RD400 are both very quick drives, so the Plextor M8Pe and ADATA XPG SX8000 will have to be at their very best in order to stand a chance.

One thing to note is that the Samsung SSD 960 Pro and OCZ RD400 were tested with custom NVMe drivers from their respective manufacturers. On the other hand, the ADATA XPG SX8000 and Plextor M8Pe were both tested using native Windows 10 NVMe drivers, because ADATA and Plextor did not release special NVMe drivers for their drives.

The following drives were tested for this review:

  • ADATA XPG SX8000 (512GB)
  • Plextor M8Pe (512GB)
  • OCZ RD400 (512GB)
  • Samsung SSD 960 Pro (512GB)

 

PCMark 8

PCMark 8 is the most up-to-date system benchmarking software from benchmarking specialists Futuremark. It was designed for Windows 8 machines (now updated for Windows 10) and the storage suite test puts drives through a collection of 10 different real life workloads involving applications such as Photoshop, Illustrator, InDesign, Word, Excel and even games like Battlefield 3 and World of Warcraft.

We begin with PCMark 8 as usual and we can see that the scores are quite tight. However, we can also clearly see that while the ADATA XPG SX8000 and Plextor M8Pe scored quite similarly, the OCZ RD400 and Samsung SSD 960 Pro were easily the better performing drives. Looking at the breakdown in speeds and individual timing scores, it is clear that the Samsung SSD 960 Pro is the fastest driving in this benchmark, followed by the OCZ RD400. 

The Samsung SSD 960 Pro’s average speed of 660.92MB/s was over 15% faster than the second-place OCZ RD400, and over 55% faster than the ADATA XPG SX8000 and Plextor M8Pe.
