If only one drive fails why would you lose all your data?
- Dylan16807 4y agoWe're trying to avoid losing any data here. So we desperately need a parity drive, which will bring the odds of data loss down to 2.3% for 4+1. (Though there are other factors that significantly complicate these odds.)
- ehzy 4y agoThe point is to not lose any data. In the example, if you need 4 drives to store 16 TB of data instead of 1, your probability of data loss is 18.6% vs 5%.
