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 RR = 2 DC
1 DC = 0.5 RR
例子:
将15 冗余比率转换为数据压缩:
15 RR = 30 DC
| 冗余比率 | 数据压缩 |
|---|---|
| 0.01 RR | 0.02 DC |
| 0.1 RR | 0.2 DC |
| 1 RR | 2 DC |
| 2 RR | 4 DC |
| 3 RR | 6 DC |
| 5 RR | 10 DC |
| 10 RR | 20 DC |
| 20 RR | 40 DC |
| 30 RR | 60 DC |
| 40 RR | 80 DC |
| 50 RR | 100 DC |
| 60 RR | 120 DC |
| 70 RR | 140 DC |
| 80 RR | 160 DC |
| 90 RR | 180 DC |
| 100 RR | 200 DC |
| 250 RR | 500 DC |
| 500 RR | 1,000 DC |
| 750 RR | 1,500 DC |
| 1000 RR | 2,000 DC |
| 10000 RR | 20,000 DC |
| 100000 RR | 200,000 DC |
