What can Qunhui nas do?

NAS (Network Attached Storage) literally means a device that is connected to the network and has the function of data storage, so it is also called "network storage". It is a dedicated data storage server. It takes data as the center, completely separates storage devices from servers, and centrally manages data, thus releasing bandwidth, improving performance, reducing total cost of ownership and protecting investment. Its cost is much lower than using server storage, but its efficiency is much higher than the latter.

There is only one computer at home, and all the information at home is stored on this computer. So the following happened:

You want to process the official documents of the company in the computer.

Your daughter wants to see photos of her graduation trip to Thailand on the computer.

Your wife wants to watch the unfinished American TV series on the computer.

Your mother wants to see photos of her granddaughter when she was a child.

No NAS:

So you chose to keep them waiting. . . Get a remote control. . . Finally, you died.

Use NAS:

You continue to use the computer to process official documents

Your daughter can use IPAD/ mobile phone to connect to NAS and view photos of graduation trip.

Your wife can use the DLNA function of TV to directly play American dramas stored in NAS.

Your mother can see your granddaughter's childhood photos by connecting to NAS with her smartphone.

Everything goes at the same time, perfect

Photos and videos taken outside can be uploaded to the home NAS. In this case, I take photos in other places and send them to the NAS at home for my parents to see on TV (as long as there is a TV box). It is a good function for young people who live in different places with their parents.

2. You and your wife are both freelance designers, working from home, and you usually need to use a lot of design materials to design.

No NAS:

These materials are stored in their own computers, occupying hard disk space.

It is stored on a mobile hard disk, so it is inconvenient for two people to use it at the same time.

Hard disk bumps, high temperature and other reasons hang up, and the original works of the week are lost.

Use NAS:

The material is stored in NAS, and two computers can access the material at the same time, thus realizing double repair.

When you are busy, you don't have to fight for the hard disk, which affects your feelings.

Using NAS as raid 1 can save data even if the hard disk is broken.

In this way, computers don't need to buy large-capacity hard disks, and so do mobile phones. 16G is enough.

You are a movie lover. The capacity of a high-definition movie is as high as 10G.

In fact, the capacity of high-definition movies is still underestimated. Generally, the capacity of 15g, 1080p is about 20G, and the original movie is 40G+.

No NAS

I think you opened a * * member in order to download such a large file. Cost-1

It takes several days to download network resources to the computer. Electricity charge-1

The house price is so expensive, there is no special study, and the computer can only be placed in the bedroom. Noise+1

You can only watch it on your computer after downloading. Want to see a mobile phone tablet? No. Convenience-1

With NAS,

NAS comes with free offline download, which costs nothing.

The power of the device is 30W when downloading, and it is 20W at ordinary times. The electricity fee for continuous start-up for one month is 30d*24h*30w/ 1000*0.6 yuan = 12.96 yuan. (One less takeaway is enough)

The normal noise is 20 dB(A), which is quieter than the friction noise of fallen leaves.

Some models have the function of video transcoding, such as 2-disc ds2 18play and 4-disc ds4 18play with high cost performance. You can browse movies on your computer/mobile phone/tablet at home/company/business trip.

4.？ amorous photo

I saw a friend who opened a computer shop. After helping others to restore the hard disk of a laptop, I found many indecent photos of the shopkeeper and the woman. But fortunately, he has a professional ethics. After watching enough with me, he deleted it

No NAS

The photos from a long time ago are all on the computer hard disk. The computer broke down and the photo was exposed.

Teacher Guan is a negative example.

Store personal data, network disk, you know, 8-second educational film, you know, necessary for old drivers.

With NAS,

As socialist successors, don't have such a thing.

Remember to add a second verification, and it is useless to get the hard disk.

5.？ You are a photographer, an engineer and a designer.

No NAS

Photography enthusiasts, engineers, designers, etc. usually have a lot of photos, videos and work files to back up.

Every time I go on a business trip, I shoot hundreds of G materials.

Baidu cloud has poor support for photos (EXIF information is not saved) and is limited by the painful network speed.

Foreign cloud access speed is slow, OneDrive and Google Photo are both in use, and they can't stand a lot of uploading and downloading.

With NAS,

Can be directly synchronized with your network disk in both directions.

Every time I go on a business trip, I will shoot hundreds of grams of material, so it is too much trouble to open a computer backup. After installing the USB copy function and inserting the USB flash drive, NAS will automatically copy the data to the folder specified by you, and there are various backup modes-incremental backup, mirror backup and multi-version backup to meet the needs of various application scenarios.

6.？ office

In the past, the company's file exchange was very troublesome.

To exchange information between departments, it is necessary to copy it with a mobile hard disk.

Colleague A copies the data into the computer first, and then it's your turn to copy the file.

But sometimes he accidentally turns off the computer after work, and you haven't finished reading it.

You won't be able to access the data, which is very troublesome to use.

You may not have encountered the above embarrassment, but in fact similar things happen every day.

Although the reading and writing speed of mobile hard disk is not slow, it is not so easy to access multi-person data.

It is very inconvenient to use it alternately, or to use a computer as a shared setting. If several people want to access the same hard disk at the same time in the office and at home, it is a waste of time and inconvenient to queue up to access files in turn.

7.

Need I say more about the importance of not losing data?

In the 1980s and 1990s, every family had photo albums, and it was interesting to look back.

Now everyone's photos and videos are stored in the hard disk, which can be viewed through computers, tablets and mobile phones.

There is a lot of information, which is stored electronically.

Losing data is definitely a very dangerous thing (it is estimated that many friends have experienced it personally)

8.

When you are writing a paper, you will recognize the differences every time you revise and save it.

Then make a backup in NAS, even if a large paragraph is deleted by mistake or covered by other words,

NAS can take you back to any modified version (my device saves 20 versions by default).

9.？ Don't worry about the computer hard disk capacity is not enough.

A computer with SSD will do.

With iscsi, you can divide the required space from NAS at will. As long as the network is built, the mapped network hard disk is as easy to use as the local hard disk.

10.？ If there are elderly people with mobility difficulties or naughty pets at home alone, you can connect the camera for remote monitoring.
