Second, buy a stable and reliable NAS hard disk. I recommend Seagate Cool Wolf's NAS hard disk. Cool Wolf is equipped with AgileArray intelligent array technology, which supports always-on and uninterrupted operation. The power consumption, error recovery, head drive, stability and streaming media processing of hard disk under multi-disk RAID configuration are optimized. The Cool Wolf hard disk with a capacity of 4TB and above is also equipped with a rotating vibration sensor, which can promote the hard disk to run more stably, manage the vibration of multiple disks and achieve long-term stability.
Third, buy a hard disk with higher security. For example, Seagate Cool Wolf cooperated with mainstream NAS vendors such as Qunhui and Huayun to launch the Hard Disk Health Management Tool (IHM), which can be used for early warning and detection of hard disk failures, making the data in NAS more secure.
