For the first time since the original Storage Pod, Backblaze is announcing a completely redesigned approach with the introduction of the first “direct wire” Storage Pod. This new Storage Pod performs four times faster, is simpler to assemble, and delivers our lowest cost per gigabyte of data storage yet. And, once again, it’s open source.

The New Storage Pod Design
Fast forward nearly 5 years as we introduce Storage Pod 4.0 and a completely new way of attaching 45 drives to the motherboard. The 5-drive backplanes are gone, replaced by individual direct wire SATA/Power connectors. In concert with this we replaced the three 4-port SATA cards with two high performance 40-port HighPoint Rocket 750 cards delivering SATA 3 throughput. Simpler to build and maintain, and seriously fast.

The New Storage Cost – $0.051 per GB
When we designed Storage Pods 2.0 and 3.0 our goal was to reduce the total cost per GB to store data. Pod 2.0 was great, but when the Thailand Drive Crisis pushed up hard drive prices we struggled to lower the cost of Storage Pod 3.0. With Storage Pod 4.0 we are pleased to announce it delivers 180TB of storage for just $0.051 per GB – our lowest cost per GB to date.
