2tb western digital purple surveillance hard drive sata 6gb/s
Digital video recorders store data on one or more internal Hard Disks. The same 3.5" SATA HDDs used in Personal Computers are suitable for NVR and DVR. Normally our NVRs and DVRs are supplied without Hard Disk so you can combine a disk of the right capacity for your need. Although the video recorders accept any type of SATA 3.5" HDD, it is not a good choice to buy a desktop hard disk because the PC drives are not designed for non-stop reading/writing, 24 hours a day, and would end up having a short life and poor performance.
These Western Digital Purple Series hard disks are instead designed for uninterrupted, 24/7, writing and guarantee the reliability and durability required in video surveillance applications.
