8.0TB HDPro2 Drive
Massive Desktop Storage Solution

When you need a massive amount of storage for your HD projects, large media files, databases, photos, or audio files, the HDPro is the ideal storage solution.

With support for RAID 5, the HDPro features an advanced distributed parity algorithm. Access to data and parity blocks are spread across all 8 drives in the array. To improve the read and write performance, RAID 5 is not limited to a dedicated parity drive, like RAID 3 solutions.

When configured with RAID 6, fault tolerance is maintained by the world class CalDigit RAID engine, ensuring that the parity information is placed on TWO drives. This block of data is completely separate from the drives used to store the data itself. This allows for ultimate protection, allowing up to two drives to fail, with the loss of any data.

Offering RAID 0, 1, 5, 6 and JBOD, the HDPro provides safe and reliable operation, all in one package, and backed by CalDigit's one year warranty.
Managing, Monitoring and Reporting Technology
Each HDPro2 features an environmental processor, which monitors and manages all aspects of the system including: hard drives, RAID array, controller, controller cache, fans, temperature, power supply, and enclosure conditions. In the event of a problem, the HDPro2 is capable of sending out an e-mail notifications.

The HDPro2 comes with RAID Shield, CalDigit's powerful and easy to use RAID administration software. RAID Shield is capable of building multiple RAID sets of they fly with a variety of options such as: cache sizes, capacities, slices, a logical unit number, RAID levels and more. This enables storage to be brought online without having to wait for initialization. RAID Shield is entirely based on the TCP/IP architecture. This means that each HDPro2 can be monitored and managed from anywhere on the intranet. Once setup, RAID Shield provides at-a-glance monitoring for multiple HDPro2 systems either locally or remotely.
A Cooler Workstation
Excessive heat can cause major issues and performance problems inside any workstation. Each and every component that is added to a workstation generates heat. These components are generally crammed into a small space, which in turn restricts airflow. The result is additional heat.

As the heat increases, the burden on the workstation rises. This slows down performance and adds additional strain to the workstation, which can cause premature failure of various components.

Unlike other RAID storage solutions, the CalDigit HDPro2 has a completely external RAID system. It is designed to minimize the heat inside the workstation. Because no additional heat is added, more reliable operation is achieved and individual components can experience a longer lifespan.
Direct Connection
Unlike Fibre Channel, SCSI, FireWire and eSATA RAID storage, the CalDigit HDPro2 features a direct connection to the PCI Express bus, utilizing the computer's bridge chip and memory system, combined with extremely high link speeds. This direct link eliminates latency introduced by the conversion of other interfaces to PCI Express, and provides superior bandwidth, availability and deployment flexibility as opposed to earlier-generation SCSI and Fibre Channel technology.

PCI Express provides error correction and adapts to the speed of the PCIe slot automatically. The CalDigit HDPro2 works with both PCIe 4 lane or 8 lane. Because PCIe has speeds of up to 250MB/s per lane, bandwidth for ultra fast data transport between the storage system and the host computer can be achieved. These speeds are roughly 5 times faster than traditional fibre solutions. The HDPro2 comes with a high quality Molex* PCI Express cable and special electronics, to ensure a stable and high quality connection. This means both incredible speeds and reliable bandwidth for high-speed data transfers.
Editing on the Go
Many RAID storage systems today are limited to use on desktop workstations. With today's advanced mobile technology, there is more and more demand for storage on the go. The CalDigit eLane-1ex ExpressCard allows for portable performance in the field, enabling users to capture, develop, edit and create content in almost any environment when using Apple's MacBook Pro or Windows-based notebook.

Because the complete hardware RAID solution is built inside the HDPro2, a separate RAID Card is not needed. This means that the HDPro2 is a completely portable hardware RAID solution.

This also means that the external RAID storage for the laptop is no longer limited to the slower FireWire and USB connections. The CalDigit eLane-1ex can reach speeds of up to 195MB/s allowing for uncompressed high definition editing on a laptop.
Built-In Intel XScale Core Processor
The HDPro2 has an integrated, state of the art, Intel XScale core to accelerate RAID performance and provides support for multiple RAID levels. By utilizing this advanced technology from Intel, the CalDigit HDPro2 provides a simple and powerful solution for professionals looking to increase performance and add protection to their storage.
Active Sustained Transfer Technology (ASTT)
ASTT was designed by CalDigit's top engineers to provide ultimate sustained performance. This advanced technology is unique to CalDigit and cannot be found anywhere else:
  • With ASTT, the performance of your HDPro2 is always kept in check. When data is transferred, any highs (peaks) or lows (drops) are equalized by the Active Sustained Transfer Technology.
  • ASTT optimizes the best transfer size and timing between the RAID controller cache and the host machine. This eliminates performance drops and maximizes the sustained data rate.
  • ASTT also helps to maintain a continuously smooth transfer rate over the whole capacity of the RAID. This technology is ideal for video editors who need sustained playback, and can't risk dropping frames.
The HDPro2 is bootable
Simply install the operating system of your choice (Mac OS X, Windows, or Linux) onto the HDPro2 and it will become completely bootable. By booting from HDPro2 the ability to troubleshoot system issues and start up disks can be achieved whenever errors are encountered.

Booting from a RAID Volume adds both flexibility and mobility. Complete and pre-configured systems can be moved to and from various locations, and can even be used with a laptop.
