When choosing between MLC (Multi-Level Cell) and TLC (Triple-Level Cell) SSDs, it's not just about picking letters - it's about matching technology to your workload. Let's break down these storage powerhouses with real 2025 data and Qootec's industry experience.
Under the Hood: How MLC and TLC Actually Work
MLC Flash Memory
Stores 2 bits per cell
Typical P/E cycles: 3,000-10,000
Best for: Industrial applications, write-intensive workloads
Check out Qootec's industrial-grade MLC SSD with -40℃ to 85℃ operation.
TLC Flash Memory
Stores 3 bits per cell
Typical P/E cycles: 500-3,000
Best for: Consumer devices, read-heavy workloads
Explore our cost-effective TLC SSDs for semi-industrial use.
Real-World Performance: Lab Tests vs Actual Use
| Metric | Qootec MLC SSD | Qootec TLC SSD | Industry Average |
|---|---|---|---|
| 4K Random Read | 98,000 IOPS | 105,000 IOPS | 89,500 IOPS |
| Sequential Write | 520MB/s | 480MB/s | 450MB/s |
| DWPD (5yr) | 3.0 | 0.7 | 1.5 |
DWPD = Drive Writes Per Day
