How accurate is the SSD health estimate?

Quick Estimate mode provides approximate health assessment based on industry average data with medium to low confidence. Precise Analysis mode uses actual SMART data from your drive, offering higher accuracy with medium to high confidence. Both modes include conservative bias and appropriate disclaimers.

How do I get SMART data from my SSD?

You can use free tools like CrystalDiskInfo (Windows), smartmontools (Linux/macOS), or manufacturer-specific utilities. CrystalDiskInfo provides detailed SMART data that can be copied and pasted into our tool for precise analysis.

What health score indicates my SSD needs replacement?

Health score 0-39 indicates critical status requiring immediate replacement. Score 40-69 suggests warning status with backup recommended. Score 70-100 indicates good health. However, always consider manufacturer specifications and consult professionals for important decisions.

Is my data stored or shared?

No. All analysis happens in your browser. We do not store, transmit, or share any data you enter. Your SSD information remains completely private and local to your device.

How often should I check my SSD health?

For regular users, checking every 3-6 months is sufficient. For heavy users (video editing, servers, intensive gaming), monthly checks are recommended. Check immediately if you notice slow performance, boot issues, or unusual behavior.

What temperature is too high for an SSD?

Normal operating range: 30-50°C during typical use. Acceptable under load: Up to 70°C for SATA drives, up to 80°C for NVMe. Consistently above 70°C accelerates wear. Critical: Above 85°C requires immediate action.

When should I replace my SSD?

Consider replacement when health score drops below 40, you see rapidly declining health, increasing SMART warnings, consistently high temperatures, or performance issues. Replace proactively when health drops below 50%. Always backup before replacement.

What is your SSD capacity?

Pro Tip

Larger capacity SSDs generally have longer TBW (Terabytes Written) lifespan. For example, a 512GB SSD typically lasts about 2x longer than a 256GB SSD.

Why SSD Health Matters

SSD health monitoring is critical for preventing data loss. Unlike HDDs, SSDs can fail suddenly without warning signs.

Prevent Data Loss

SSDs can fail suddenly without warning. Regular checks help you backup before it's too late.

Understanding Your Results

Our tool provides a health score from 0-100 based on industry factors. Here's how to interpret it:

Health Score	Status	Recommended Action
70-100	Good	Continue regular monitoring every 3-6 months
40-69	Warning	Backup data immediately; plan for replacement; monitor monthly
0-39	Critical	Backup all data now; replace drive as soon as possible

Important Notes

These scores are estimates based on available data
A "Good" score doesn't guarantee future performance
Always consult manufacturer tools for definitive assessment

TBW (Total Bytes Written)

How much data your SSD can write before expected failure. Higher TBW ratings mean better endurance.

Calculate TBW

Operating Temperature

Sustained temperatures above 70°C accelerate wear and reduce lifespan. Keep your SSD cool.

Factors Affecting SSD Lifespan

Understanding what impacts your SSD's longevity helps you make informed decisions about maintenance and replacement.

TBW Rating

Manufacturer's write endurance rating. Higher TBW = longer life.

Samsung 970 EVO: 1,200 TBW | Crucial MX500: 360 TBW

Write Intensity

Heavy write workloads (video editing, servers) reduce lifespan faster.

Consider high-endurance SSDs for intensive use cases

Operating Temperature

Sustained temperatures above 70°C accelerate wear. Keep SSD below 50°C.

NVMe drives benefit from heatsinks in gaming PCs

Free Space

SSDs need free space for wear leveling. Keep at least 10-20% free.

Near-full drives experience reduced performance and accelerated wear

Drive Age

Most SSDs last 3-5 years under normal use. Older drives need more monitoring.

Electronic components degrade over time, even with low write usage
