I am a huge fan of BackBlaze’s online backup and they have just released version 3 of their amazing storage pods. These Storage Pods are all about big storage at low low costs, they are the backbone of BackBlaze’s storage pools and at 180TB of storage at $59.54 a TB they help keep the subscriptions fees down. To break that down further it’s only $0.0595 per GB! If you are interested you can actually purchase a complete unit yourself or build one DIY style.
