The system that I am using is to test most of the hardware. The same operating system, choice of USB 3.0 port (specific rear I/O port) version of benchmark software and the testing method is maintained throughout the graph.

Operating System Windows 10 64-bit Pro
Processor+ Cooler Intel i7 4790k + Noctua NH-U12S
Motherboard Gigabyte Z97X-Gaming GT
RAM 8GB Kingston DDR3 HyperX
Primary Storage 240GB SanDisk Extreme II SSD
Secondary Storage 3TB WD Red WD30EFRX
Power Supply Corsair TX750
PC Case Lian Li A70F

The testing methods are as follows:

Anvil Benchmark

  • Access Test
  • Transfer Rate Test

AS SSD Benchmark

  • IOPS Test- Sequential- 16MB, 4K and 4K-64 Thrd
  • MB/s Test- Sequential, 4K and 4K-64 Thrd

ATTO Benchmark- Read and Write

CrystalDiskMark Benchmark

  • 1 GiB- Read and Write
  • 32 GiB- Read and Write

Futuremark Benchmarks

  • PCMark 7 Benchmark
  • PCMark 8 Benchmark

IOPS Testing

  • 4K and 256K Read and Time- Total IOPS
  • 4K and 256K Read and Time- Average IO Response Time

SSD Access Test

  • Read: Min./Max./Average
  • Write: Min. Max./Average

Drive Format: NTFS

The test that I am doing is with a newer system and, therefore, it’s not compared with the drive’s benchmarks tested on the older test setup due to the change of USB 3.0 controllers. But if you want to know the older benchmark data, you can check the last review which was done on the older test setup.

  1. Thanks for the review, could you give us some ideas about “Better options out there for heavy workloads”? Which drives could you recommend for that? I couldn’t see the options on the review… Thanks!

  2. I tested the SanDisk Extreme Pro:

    I haven’t test Samsung 850 Pro, but you can google out for reviews and make a decision accordingly. I hope it helps. You could check out M.2 based SSDs too.
