Backblaze has announced that it has updated its budget-priced Storage Pod concept, doubling the capacity and performance while lowering the cost below the original design. The second-generation model now represents a 135TB server fitting into the same 4U rack space, with component costs totaling just $7,384. Although the company uses the Storage Pod 2.0 for its own $5/month backup service, the design is free to use for do-it-yourself projects.
