Why a 1TB SSD shows up as 931GB
Drive makers count 1GB as one billion bytes; Windows counts it as 1,073,741,824. Same storage, two rulers, so 1TB reads as 931.32GB. Here is how to tell where the unit difference ends and formatting overhead begins.

TLC vs QLC SSDs: 100GB Takes 12 Minutes Once Cache Runs Dry
QLC drives match TLC only while the SLC cache holds. Once it drains, writes collapse to 50-150MB/s and a 100GB copy stretches to nearly 12 minutes — and the fuller the drive, the sooner that cliff arrives.
SSD Endurance: How Long 600TBW Really Lasts at 20GB a Day
Burning a 1TB SSD's 600TBW inside five years takes 329GB of writes a day. At 20GB a day it takes 82 years. Converted to DWPD, every capacity lands on the same 0.33.
PCIe Gen4 vs Gen5 SSD: When Double the Bandwidth Does Nothing
A PCIe 5.0 SSD reads sequentially at 14,800MB/s, roughly double a Gen4 drive. Measured game load times differ by under 0.2 seconds. Here is the bandwidth, heat and endurance math that explains the gap between the two facts.
SSD NVMe vs. SATA — 10x Faster on Paper, Where You Feel It
SATA tops out at 550 MB/s; NVMe PCIe 4.0 reaches 7,500 MB/s — specs differ by 10x, but boot-time feel is similar. Here is where the gap actually opens up and what to check before looking at speed.
