Other World Computing (OWC®), a leading zero emissions Mac upgrade and storage technology company announced the new 20TB capacity for the OWC ThunderBay IV line of four-bay external high-performance storage solutions, one of OWC's family of Thunderbolt interface storage products.

The ThunderBay IV, now available with up to 20TB of total storage, adds tremendous storage capacity and throughput to any Mac or PC with a Thunderbolt port. Applications such as A/V post-production, photography, music, graphics, data management, and even Time Machine backups are enhanced with access to data at sustained data rates of up to 887MB/s read, 884MB/s write.

Flexible for Individual Storage Needs
The ThunderBay IV supports independent drive access of up to four installed drives, is fully RAID ready, and is ideal for software RAID 0, 1, and 5 configurations. Even combinations of RAID, individual drive(s) or multiple RAID sets are possible with OWC ThunderBay IV.

"The new 20TB capacity of the ThunderBay IV is a real benefit to all users, especially for anyone working with 4K content and its larger capacity needs," said Larry O'Connor, Founder and CEO, Other World Computing. "Now users can have blazing fast Thunderbolt technology performance and a new option for 20TB of storage space."

A durable aluminum enclosure protects the four internal drives and keeps them cool thanks to its superior heat dissipation. In addition, the locking faceplate keeps the installed drives secure at all times.
