Storage Lifespan Calculator
Estimate how long your SD card or SSD will last.
Total Capacity
0.50 TB
Daily Writes
0.0050 TB
Estimated Lifespan
3 months
Write Amplification: Actual lifespan may be 30-50% shorter due to write amplification and filesystem overhead.
Optimization Tips
With log2ram
Keep /var/log in RAM, syncing periodically. Eliminates constant log writes.
With noatime
Disable access time tracking on file reads. Reduces metadata writes.
Both Combined
Using log2ram and noatime together. Maximum write reduction.
What is a storage life calculator?
A storage life calculator estimates how long a storage device (SSD, HDD, or flash drive) will last based on its rated endurance and your usage patterns. SSDs have a finite number of write cycles — measured in TBW (Terabytes Written) or DWPD (Drive Writes Per Day). This tool calculates the expected lifespan based on your daily write volume.
Modern SSDs are surprisingly durable — a consumer SSD rated at 600 TBW can handle writing 600 terabytes of data over its lifetime. For most users writing 20-50 GB per day, that is decades of use. However, write-heavy workloads like databases, video editing, or surveillance recording can wear out drives much faster. This calculator helps you plan replacement schedules.
How to use this tool
Enter the drive's TBW rating (from the specification sheet) and your estimated daily write volume. The tool calculates the expected lifespan in years. It also shows how different usage patterns would affect longevity and whether you should choose a consumer or enterprise-grade drive.
Understanding SSD endurance
- TBW (Terabytes Written) — total amount of data that can be written before expected failure. Consumer SSDs: 150-600 TBW. Enterprise: 1,000-30,000+ TBW.
- DWPD (Drive Writes Per Day) — the fraction of the drive's capacity that can be written per day over the warranty period. 1 DWPD on a 1TB drive over 5 years = 1,825 TBW.
- NAND types: SLC (highest endurance, most expensive) > MLC > TLC > QLC (lowest endurance, cheapest).
- Write amplification — the SSD controller may write more data internally than the host requests, reducing effective endurance. Overprovisioning helps mitigate this.
SSD vs HDD lifespan
HDDs fail from mechanical wear (motor, bearings, heads) rather than write endurance. Their lifespan is measured in hours of operation (MTBF — Mean Time Between Failures), typically 1-2 million hours. In practice, consumer HDDs last 3-5 years on average. SSDs have no mechanical parts but wear out from write cycles. For read-heavy workloads (media storage, backups), both last many years. For write-heavy workloads, enterprise SSDs significantly outlast HDDs.
Frequently asked questions
How do I check how much I write per day?
On Linux: check SMART data with 'smartctl -a /dev/sda' — look for 'Total_LBAs_Written' and convert to GB. On Windows: use CrystalDiskInfo. On macOS: use 'smartctl' from Homebrew. For a rough estimate: regular office/web use writes 10-20 GB/day, software development 20-50 GB/day, video editing 50-200+ GB/day, database servers 100-500+ GB/day.
Will my SSD die suddenly without warning?
SSDs typically degrade gradually. SMART monitoring provides health indicators: 'Media_Wearout_Indicator' or 'Percentage_Used' shows remaining endurance. Most SSDs become read-only when their write endurance is exhausted rather than losing data — you can still read your files but cannot write new ones. Set up SMART monitoring alerts to get warned well before failure.
