SSDs are better at handling physical impacts because they lack moving parts. On the other hand, HDDs have delicate mechanical components that are more prone to damage from sudden movements. SSDs also perform well in tough conditions, such as environments with vibrations, extreme temperatures, or magnetic fields [6]. This makes them ideal for laptops, portable devices, industrial settings, military use, aerospace applications, and outdoor fieldwork.
These physical differences directly affect how long you can expect each type of drive to last.
Expected Lifespan
The average lifespan of storage drives varies:
| Drive Type | Average Lifespan | Durability Factors |
|---|---|---|
| HDD | 4–7 years | Mechanical wear, operating temperature, usage patterns |
| SSD (SLC) | 5–10 years | Write cycles (100,000 P/E), power stability |
| SSD (MLC) | 5–10 years | Write cycles (10,000 P/E), temperature |
| SSD (TLC) | 5–10 years | Write cycles (3,000 P/E), usage intensity |
SSDs use a technique called wear-leveling to extend their lifespan. However, when SSDs fail, it often happens suddenly, while HDDs typically show signs of wear before failing [7].
These differences extend to reliability metrics as well.
Reliability Statistics
Data from Backblaze‘s storage analysis sheds light on how reliable these drives are:
| Reliability Metric | SSD | HDD |
