CalDigit HDPro2 Controller Only

The CalDigit HDPro2 offers the best gigabyte-per-dollar ratio in the world for hardware RAID storage. The HDPro2 is a high-performance storage solution with capacities from 8TB to 16TB. At under $1 per gigabyte, including the PCI card and all required accessories - it's a fraction of the cost compared to other products in its class. The CalDigit HDPro2 uses SATA 3Gb/s drives with up to 32MB cache, this means performance that meets the needs of the most demanding video and content editing software.

Each 7200-RPM SATA hard drive connects to a dedicated SATA channel to eliminate bottlenecks and maximize the 3Gb/s native SATA connection. The HDPro2 also supports SAS drives for the ultimate in performance, speed and reliability. SAS drives spin at 10,000-RPM and can provide additional performance and reliability. The HDPro2 utilizes the fast PCIe infrastructure to connect directly to the host computer.

Instead of using the RAID controller inside the workstation, the HDPro2 has it built inside. Using external PCIe, CalDigit is able to achieve a direct connection to the host with no delay or conversion unlike fiber solutions. This powerhouse delivers up to 720MB/s with RAID 5 protections. The HDPro2 delivers sustained data throughput, providing the fastest sustained data rate in its class. These graphs illustrate how the HDPro2 is able to keep up with the most demanding real-world scenarios.

Optimized for video playback, the HDPro2 means dropped frames are a thing of the past. Other RAID storage solutions are capable of playing back 10-bit 4K uncompressed footage in bursts, but dropped frames are commonly experienced after just 2-3 minutes or less of playback. The HDPro2 is a true editing solution that maintains its data rates during both editing and playback!

Each HDPro2 holds 8 hot swappable drive modules in a desktop tower; optional rack mount kits are available. The hot swappable functionality of the HDPro2 allows users to upgrade the drive's capacity as needed, while remaining very easy to configure. There is no capacity limitation to any single chassis.
