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
We have also revised our benchmarks and the list used are as follows:
- 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)
This is the list of drives and their capacities tested:
- Plextor M7V (512GB)
- OCZ Trion 150 (480GB)
- Samsung SSD 750 Evo (250GB)
- Sony SLW-M (480GB)
- Samsung SSD 850 Evo (250GB)
- Plextor M6 Pro (256GB)
Given the positioning and claims by Plextor, we will be looking closely at how the M7V performs against the current crop of TLC-NAND drives, such as the OCZ Trion 150 and Samsung SSD 750 Evo and SSD 850 Evo. But bear in mind here that the Samsung drives are of a smaller capacity and so are expected to perform poorer. We also want to find out how the M7V will fare against Plextor’s last flagship SATA-based SSD, the M6 Pro.
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.
The Plextor M7V got off to a disappointing start on PCMark 8. Its score of 4875 was the lowest recorded. And if we look deeper at the recorded speeds, we can see that it only managed 145.5MB/s, which was the slowest by some margin. The next slowest drive was the Sony SLW-M which recorded a speed of 198.43MB/s - that’s over 36% faster. The fastest drive was, surprisingly, the 250GB Samsung SSD 850 Evo, which recorded a speed of 302.38MB/s. That’s over twice as fast as the Plextor M7V!
