TBW (Terabytes Written) is a key metric that determines SSD lifespan.
TBW (Terabytes Written) is a key metric that determines SSD lifespan.
What Does TBW Mean
TBW refers to the total amount of data that can be written to an SSD before it may fail.
Example
- 500GB SSD with 300 TBW → You can write 300 terabytes over its lifetime
Why TBW Matters
- High-write environments need higher TBW
- Low TBW may lead to early failure
TBW vs DWPD
- TBW = total lifetime writes
- DWPD = writes per day
How to Choose
- Office use → low TBW acceptable
- Industrial → high TBW required
