The core of R12 is Promise’s proprietary storage technologies – PromiseRAID and Boost Technologies – that enhance performance, security, and stability. Battle-tested across industries by millions of users, PromiseRAID in particular leverages the Predictive Data Migration (PDM) feature to deliver unparalleled reliability – the company’s Promise – and keep hard-won creative work safe from disk failure while maximizing performance, particularly effective on high-capacity, multi-drive systems. It also serves as the cornerstone for Boost Technologies, which give creative studios and media companies more storage optimization solutions that enhance performance, security, sustainability, scalability, and stability.

Partnership with AJA
Long a key player in storage technology for the M&E industry, Promise is advancing its Rich Media ecosystem and better serving customers through collaborations with brands such as AJA Video Systems. The latest result of this partnership is a specialized setup combining AJA’s capture and output solution Io 4K Plus with Pegasus M4 compact desktop storage solution.

Chang added: “Also at IBC, we are celebrating our partnership with AJA to enable seamless video processing via Pegasus M4 and AJA Io 4K Plus. The combined setup ensures that – once video files are converted and stored in Pegasus M4 – the data is secured by PromiseRAID, while four integrated SSDs always guarantee exceptional performance and speeds throughout the video ingesting and editing process.”

Developing technology that helps streamline and accelerate creative workflows as they continue to grow in complexity remains a key focus for AJA, and those efforts extend into our partner collaborations. Our latest work with Promise supports this mission, enabling a powerful setup between AJA Thunderbolt solutions and the Pegasus M4 that provides the I/O and storage performance and speed to keep pace with modern workflow demands,” said Nick Rashby, president, AJA Video Systems.
