Our samples were tested according to our standard hard drive testing methodology. As of mid-2008, we have been conducting most acoustics tests in our own 10~11 dBA anechoic chamber, which results in more accurate, lower SPL readings than before, especially with sub-20 [email protected] devices.

Two forms of hard drive noise are measured:

  1. Airborne acoustics
  2. Vibration-induced noise.

These two types of noise impact the subjective perception of hard drive noise differently depending on how and where the drive is mounted.

Both forms of noise are evaluated objectively and subjectively. Airborne acoustics are measured in our anechoic chamber using a lab reference microphone and computer audio measurement system. Measurements are taken at a distance of one meter from the top of the drive using an A-weighted filter. Vibration noise is rated on a scale of 1-10 by comparing against our standard reference drives.

As of late-2011, we have been conducting performance testing. A combination of timed real-world tests is used to represent a workload of common activities for a boot drive including loading games, running disk-intensive applications, copying files, and installing programs.

Summary of primary HDD testing tools:

Drive Test Platform:

  • Intel Core i7-6700K processor - four cores. 4.0~4.2 GHz, 14 nm, 91W, Hyper-threading, integrated Intel HD 530 graphics, underclocked to 1.6 GHz
  • Asus Maximus VIII Gene - Z170 chipset, microATX
  • Noctua NH-L12 cooler - stock 120 mm fan only
  • Kingston Fury memory - 2x8GB DDR4-2667, C15
  • Kingston HyperX 3K solid-state drive - 120GB, 2.5-inch, SATA 6 Gbps
  • Seasonic SS-460FL power supply - 460W, ATX, fanless.
  • Microsoft Windows 10 operating system - Professional, 64-bit

Real World Performance Test Tools:

Real World Benchmark Details:

  • Boot: Time elapsed between pressing the power button and Windows start sound playing (minus the time for an average SSD to get to the first load screen, about 12 seconds on our test system) .
  • CIV: BE: Time elapsed between canceling the introduction scene and appearance of the opening menu.
  • Photoshop: Time to load Photoshop CC.
  • COD: WAW: Combined time to load the "Black Cats" and "Breaking Point" levels of Call of Duty: World At War
  • ExactFile: Time to create a MD5 check file of our entire test suite folder.
  • TrueCrypt: Time to creating a 10GB encrypted file container.
  • 3DMark 11: Install time, longest interval between prompts.
  • OpenOffice: Install time, longest interval between prompts.
  • Small File Copy: Copy time for a variety of small HTML, JPEG, MP3, ZIP, and EXE files.
  • Large File Copy: Copy time for 4 AVI files, 2 x 700MB and 2 x 1400MB in size.

A final caveat: As with most reviews, our comments are relevant to the samples we tested. Your sample may not be identical. There are always some sample variances, and manufacturers also make changes without telling everyone.

Ambient conditions at time of testing were 10.5 dBA and 20~23°C.
