๐พ Flash Reliability Assessment
Your 2TB TLC SSD has an immense endurance rating of 1,200 TBW. Even with weekly 100GB patches and Shadowplay recording writing ~115 GB total per week, you consume only 3.5% of your NAND endurance each year. You will upgrade your entire PC long before this SSD wears out.
Frequently Asked Questions
What does TBW (Total Bytes Written) mean on an SSD?
TBW is the manufacturer's endurance rating indicating how many terabytes of data can be written to the flash memory cells before the NAND degrades. For example, a 2TB TLC SSD (like the Samsung 990 Pro or WD Black SN850X) is rated for 1,200 TBW, meaning you can write 1,200,000 Gigabytes of data before reaching guaranteed endurance limits.
Do game updates like Call of Duty (100GB) wear out my SSD fast?
Modern games frequently download 30GB to 100GB patches that overwrite files. While this sounds large, a typical 1TB TLC SSD with 600 TBW can survive over 6,000 full 100GB updates! For normal gamers downloading 150GB weekly, the drive will easily last 10 to 15+ years before NAND exhaustion.
Why is TLC NAND better for gaming than QLC NAND?
TLC (Triple-Level Cell) stores 3 bits of data per cell and typically lasts 600 TBW per terabyte. QLC (Quad-Level Cell) squeezes 4 bits per cell, halving endurance to ~300 TBW per terabyte. Furthermore, once QLC's fast SLC cache fills during a huge 100GB download, write speeds can plummet down to HDD-like speeds (50-80 MB/s).
