| Safe, Reliable storage.jpg) 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 3 year warranty. technical specifications | .jpg) Size and weight ● Height: 15.88 inches ● Width: 7.05 inches ● Depth: 10.24 inches ● Weight: 36.0 lb In the box ●HDPro Unit x 1 ● PCI-E or PCI-X card x 1 ● PCI Express Cable X 1 ● Drive Trays X 8 ● Installation CD ● Power Cord X 1 | Storage ●Eight independent 3Gb/s SATA hard drives directly attached to the computer board, Maximum 8 TB of storage capacity using 7200RPM SATA II 3G diskdrive. ● Eight independent 3Gb/s SATA hard drives directly attached to the computer board. ● Maximum 8 TB of storage capacity using 7200RPM SATA II 3G disk drive.
