Blackmagic Design HDD Case The Blackmagic Design HDD Case is a specialized, ruggedized media enclosure designed for the Blackmagic URSA Cine and PYXIS 6K ecosystems. Unlike the SSD Case which utilizes NVMe technology, the HDD Case is specifically engineered to house high-capacity 2.5-inch SATA drives, providing an ultra-low-cost storage solution for long-form recording where maximum capacity is prioritized over extreme data speeds. Design and Utility The HDD Case is built to bridge the gap between professional cinema acquisition and affordable IT storage: SATA Interface: Specifically designed to accept standard 7mm or 9.5mm 2.5-inch SATA SSDs or HDDs. This allows users to utilize existing high-capacity SATA drives that are common in server environments. Direct Camera Integration: Much like the NVMe version, this case slides directly into the camera's media module slot. This creates a secure, internal connection that is far more reliable than an external USB-C cable dangling from the side of the rig. Machined Aluminum Housing: Provides mechanical protection for the drive and assists in heat dissipation, ensuring the drive stays within safe operating temperatures during extended recording sessions. Workflow Applications Extreme Capacity: While NVMe drives are faster, SATA SSDs (like the Samsung 870 QVO series) are available in massive 8TB capacities at a fraction of the price. This makes the HDD Case ideal for "set-and-forget" scenarios like long interviews, time-lapses, or security/surveillance-style filming. Archival Recording: Because SATA drives are inexpensive, production houses can treat the drive inside the case as a "digital negative," archiving the entire drive rather than offloading and reusing it. Compatibility with Media Docks: Once removed from the camera, the HDD Case can be inserted into the Blackmagic Media Dock, allowing for high-speed 10G Ethernet access to the footage on a network. Performance Considerations It is important to note the technical differences between this and the SSD (NVMe) Case: Speed Limits: SATA technology is capped at approximately 560 MB/s. While this is plenty for 6K Blackmagic RAW (BRAW) at standard frame rates, it may not support the extreme high-frame-rate 12K recording modes found on the URSA Cine. Vibration Sensitivity: If using a mechanical Hard Disk Drive (HDD) instead of a Solid State Drive (SSD) within the case, the camera should be kept stationary (tripod-mounted). Mechanical drives are susceptible to "head crashes" if subjected to the bumps and vibrations of handheld or gimbal work. Comparison: HDD Case vs. SSD Case Feature HDD Case SSD Case Drive Type 2.5" SATA SSD / HDD M.2 NVMe SSD Max Typical Speed ~560 MB/s ~3,500+ MB/s Best Use Case Long-form 6K, Documentary 12K, High Frame Rates Cost per TB Lowest Moderate Operational Tip If you are using the Blackmagic HDD Case for critical production, always opt for a SATA SSD over a mechanical HDD. The lack of moving parts in an SSD makes it significantly more reliable for cinema use, and the price difference is now negligible compared to the risk of losing footage due to mechanical failure.
