Backblaze is in the business of providing online backup service and, by extension, wound up in the hardware business. Upset with the high cost of storage devices, the company designed and built it's own 67TB storage modules for about $7867 (materials alone) each. Now, CEO Gleb Budman says Backblaze is giving away the design, hoping the open approach will lead to improvements or inspire a separate company to build the boxes so Backblaze doesn't have to.
