About Real Capacity

Due to a standard difference in how manufacturers and operating systems calculate storage, the displayed capacity on your PC may be slightly lower than the labeled size:

• 4GB ≈ 3.6–3.9 GB
• 8GB ≈ 7.4–7.8 GB
• 16GB ≈ 14.2–15 GB
• 32GB ≈ 28–30 GB
• 64GB ≈ 58–60 GB
• 128GB ≈ 110–120 GB

This is a normal calculation difference: your PC defines 1 GB = 1.073741824 billion bytes, while the market standard defines 1 GB = 1.00 billion bytes. All units pass H2testw and are 100% real capacity.
