系统内冗余或重复数据的度量，表明存储和潜在性能问题效率低下。
1 RF = 1 TC
1 TC = 1 RF
例子:
将15 可靠性因素转换为涡轮代码冗余：
15 RF = 15 TC
| 可靠性因素 | 涡轮代码冗余 |
|---|---|
| 0.01 RF | 0.01 TC |
| 0.1 RF | 0.1 TC |
| 1 RF | 1 TC |
| 2 RF | 2 TC |
| 3 RF | 3 TC |
| 5 RF | 5 TC |
| 10 RF | 10 TC |
| 20 RF | 20 TC |
| 30 RF | 30 TC |
| 40 RF | 40 TC |
| 50 RF | 50 TC |
| 60 RF | 60 TC |
| 70 RF | 70 TC |
| 80 RF | 80 TC |
| 90 RF | 90 TC |
| 100 RF | 100 TC |
| 250 RF | 250 TC |
| 500 RF | 500 TC |
| 750 RF | 750 TC |
| 1000 RF | 1,000 TC |
| 10000 RF | 10,000 TC |
