For hard drive capacity measurements, 1GB = 1 billion bytes; actual formatted capacity less by 5% base on OS. Maximum capacity of 48TB achieved through use of 24x2GB Nomadic 4U Drive Modules. 3.4GB/sec. Actual rates will vary based on host interface. Weight varies by configuration and manufacturing process. GVS custom configures each Nomadic 4U based on customer specification from block size. Each drive goes through an extensive burn-in period prior to shipment.
