The article states:
"Wasabi’s durability is 11 x 9s, the same as Amazon S3. To put that in context, if you stored 1 million 1 GB files in Wasabi, you would expect on average to lose one file every 659,000 years"
Can someone walk me through the math here? I specifically curious about why the size of the file being 1 GB is relevant to the calculation.
- CobrastanJorji 9y agoIt doesn't matter. This is marketing fluff. What companies like Amazon do is count how many hard drives would need to simultaneously fail to lose data, calculate the odds of a hard drive losing data, and then multiplying. This gets you to 11 9's. In practice, this is almost certainly not going to be why you lose data. That will be because of a chain of human errors, or a code bug, or because the user accidentally deleted the data, or because earthquakes destroyed your data centers. I don't know anything about Wasabi other than what's on their web page, but I half suspect that what they did was look at Amazon's durability guarantee and then write that number down as their durability guarantee.
- jjeaff 9y agoYes, I think is disingenuous to call it "data" durability. "disk" durability would be more accurate.
