Hello everyone, I'm autumn corn kernels.

NAS, or networked storage, has entered the public eye in recent years, but it has also been controversial, some people think it is an artifact to improve the quality of life, and some people think it is an IQ tax. So, what exactly is NAS?

Let's talk about practicality and application scenarios first. For photography enthusiasts, NAS is a large-capacity material library, which can safely store massive high-definition photos and video materials, which is convenient for calling at any time. Film and television enthusiasts can also turn the NAS into a home video library, bid farewell to the membership restrictions of the video platform, realize the free local playback of 4K and Blu-ray HD movies, and automatically capture the cover, score and other information to form a poster wall. Home users can use the NAS to build a family photo album, so that family members can view and upload photos and videos at any time.

Data security is one of the core advantages of NAS. Many NAS support RAID disk array technology, such as RAID5, which can realize data mirroring backup, and a hard disk will not be damaged without data loss; RAID0 uses parity information to recover data, making it more fault-tolerant. At the same time, user permissions can also be set, and different family members have different access rights to protect personal privacy.

Multi-device collaboration is also very powerful. Whether it's a mobile phone, tablet, or computer, you can easily connect to the NAS to synchronize and share data. Edit half of the document in the office and continue on your phone when you get home, without the need for tedious transfer steps.

In terms of charging convenience, NAS is usually connected to a power supply, as long as the power supply is stable, and there is no need to charge as often as mobile devices. In terms of value retention, NAS of well-known brands has a relatively high value retention rate due to its mature technology and reliable quality.

NAS is not an IQ tax, it has obvious advantages in data storage, security and multi-device collaboration, as long as you are clear about your own needs, reasonable choice and use, you can bring great convenience to life and work.
