Re: FUD or did you not do your homework?

ManMountain1, it looks like the confusion is coming from the following line in the article:
1PB effective capacity in 3U, 183 TB raw
This is not the case, looks like the author multiplied 10x18.3 instead of 20x18.3. If you look at Pure's graphic and also the second to last paragraph in the article, you can see that the 1PB effective capacity is based on 20 18.3TB drives at a 5:1 data reduction ratio. The output of the math adds up, just make sure you are using the right inputs ;)
