Test Group B is an in-depth test of the platform's storage client DriveShare, a software that enables users to earn money by sharing extra hard drive space. The Storj Test Group B has reached 1,173 terabytes in storage space and currently supports 293 users online.

"We're extremely pleased by the support and validation we've received from our community," said CEO Shawn Wilkinson in a statement. "We're excited to release the world's first crowdsourced cloud storage platform."

The Test Group B network test is set to run until late October, with increased rewards and test group participants. In recognition of the 1 petabyte milestone, Storj Labs has increased the testing rewards pool from 100,000 Storjcoin X (SJCX) to 1 million SJCX, which is currently worth around $16,000.
