Environment

Operating System

Windows® 10*, Windows® 10, 32-bit*, Windows® 10, 64-bit*
Intel® SSD 660p Series (2.0TB, M.2 80mm PCIe 3.0 x4, 3D2, QLC).

Description

After having the SSD installed as a secondary drive, how much capacity will be available for usage after installed?

Resolution

The answer will vary from system to system. However it will be necessary to do a conversion to get an approximation.

  • The true conversion from bytes to gigabytes must use 1024 instead of 1000, so 16,000,000,000 bytes are actually the following gigabytes: 16,000,000,000 / 1024 = Kilobyte value
  • Kilobyte value / 1024 = Megabyte value
  • Megabyte value / 1024 - Gigabyte value = 14.9 GB
  • Having said this, 2 Terabytes (TB) are 2,000,000,000,000 bytes, so you would have to divide that number by 1024 four times to get the approximate true TB value. That would be approximately 1.8 TB (1.81898940...TB)

The capacity on the Intel® SSD label is calculated in decimal notation. Most operating systems calculate a drive capacity in binary notation.

For decimal notation, 1 GB equals 1,000,000,000 bytes.

For binary notation, 1 GB equals 1,073,741,824 bytes.

The operating system normally indicates less drive capacity than what is on the SSD label.

If the drive capacity isn't the issue, do a low-level format, and try the installation again.
