How is Hadoop able to provide such high capacity at lower costs than other relational database deployments?
JOiseau 2 years ago
What is it that is so different about Hadoop that allows it to keep cost per terabyte of hard disk capacity so much cheaper than other NoSQL processing platforms? One figure I just saw was Hadoop can support 4TB of hard disk capacity per node, with each node costing around $4000, while other choices were averaging from $10-12,000 per terrabyte. This is such a huge difference, and I'm wondering exactly why this is.
