Do SSDs Wear Out?
Yes, SSDs have a limited lifespan related to how many times their NAND memory cells can be written to. However, in normal use, a modern SSD will outlast most of the devices it's installed in.
What Is TBW and Why Does It Matter?
TBW (Terabytes Written) is the official SSD lifespan metric: how many terabytes of data can be written before cells begin degrading. Typical values: 256GB SSD: 150-300 TBW; 512GB SSD: 300-600 TBW; 1TB SSD: 600-1200 TBW. The average user writes 10-40 GB/day. A 300 TBW SSD would last over 20 years of normal use.
What SSDs Actually Fail From
SSDs rarely fail from write wear. More common causes: power cuts without UPS protection during writes, sustained overheating, manufacturing defects (first 6 months or after 5+ years), and firmware corruption.
How to Maximize Your SSD Lifespan
- Keep the SSD below 85-90% capacity
- Keep TRIM enabled (Windows does this automatically)
- Ensure good device ventilation
- Never defragment an SSD (unnecessary and accelerates wear)
- Use a UPS if power outages are frequent
