When the computer's hard disk is full, the first idea for most users is to buy a few TB of hard disk to expand. If it is a user of a laptop, the first thought is to buy an external hard disk to back up data. There is nothing wrong with it. That's when you don't even know that there is a good use of NAS. If you know about NAS as a private network storage server, maybe you will change your thinking and thinking so that the sharing and sharing of files can be more convenient. At the same time, you can access it on mobile devices and cross-platform, not very Is it convenient?
For NAS, most users still do not understand what it is? Even some people may be resistant to understanding new things because they do not understand or understand. They want to use the simplest way to do data backup and hard disk expansion. However, this is not a long-term solution. Assume that the hard disk suddenly breaks down. Oops, there is no additional backup of the data. What should I do? Can data be saved? Only one hard disk data protection, do you feel enough? If it is to record your full memory or important documents, I think this is definitely not worth the candle.
Is there any other more recommended method for data protection? In fact, there are, and with the development of public clouds, private clouds are also becoming more prevalent. Some people even retrofit through obsolete computers and install software to make him an ultra-low-cost NAS. Although this is a good choice, but the technical threshold is a bit high, you have to first brush the BIOS, recharge, install, for the novice, this is not the most convenient solution, because we as users, it is simple , Fast, convenient, too complicated procedures will let us return to the most original backup method.
What exactly is a NAS? In fact, NAS (Network Attached Storage) is a small cloud server, and it is also a small computer. When connected to the Internet at home, it can read and write on the NAS server through the network. The information.
First, more convenient data sharing access and rights management
In the past, the company’s file exchange can be said to be very troublesome. To exchange information between departments and departments, you have to use a mobile hard disk to copy files. Co-workers A first copy the data to a computer and then copy the file you want. , sometimes even ask my colleagues to connect the hard disk to the computer first, and then open the shared magnetic zone to let you go to his computer to access, but sometimes he accidentally shuts down the computer after work. If you haven't done it yet, you will not be able to save it. Take information, use very troublesome.
You may not have encountered the above situation, but in fact, similar things happen every day, although the read and write speed of the mobile hard disk is not slow, but the access to multi-person data is not so easy, have to exchange the use of , Or a computer as a shared setting, very inconvenient. If several people at the same time in the office or home have access to the same hard disk, they have to queue up to access the files in turn, causing time waste and inconvenience.
In the traditional mobile hard disk, data access must be connected to a USB cable. Some USB power is insufficient. An AC adapter must be additionally connected to allow the external hard disk to rotate. If the external hard disk crashes or falls, data may be created. Read and write problems. Because the external hard disk is not fixed in place equipment, but can let you walk around. Hard disk is most afraid of collision, but also makes it exist in such a dangerous environment, data security is very worrying.
But now, you can directly insert the hard disk into the NAS through the cooperation of the NAS. You only need to store the data in the NAS. You can share the disk through the network. Even if the computer is turned off (NAS standby), you can still Through NAS, the data is captured and used, and the disk can also be managed and restricted according to the user's authority. The power consumption of a NAS is even lower than that of a general computer. In the long-term standby, it is not necessary to worry about the power bill because it is only about 10 W, which is a few hundred W compared to a computer that is turned on. Electricity.
Second, faster processing speed, hardware equipment upgrade
When it comes to hardware devices, I have to mention that the external hard disk is the most frustrating place for me. I have bought two external hard drives. As a result, the interface will pick up a bit because of prolonged use and USB plugging. Some USB transfer lines may not be able to read when connected, and even if formatted? In this situation, of course, the author will not be easy to go on (but some people will go to point), once the point goes on the information is gone.
The use of external hard disk is afraid that it will cause irreparable problems due to shaking the bad track, the connection between the transmission line and the transmission port. If the hard disk is properly connected to the computer, it will not touch it. It will not cause the interface to consume, nor will it cause unreadable problems. In addition, because the USB2.0 transmission lines were early, even if it is now USB3.0, but the speed is still less than Gigabit intranet transmission and data access, the speed of a drop in the data transfer on the external hard drive It is not suitable for instant access and editing at any time, because as long as one line arrives, the connection may be interrupted and the convenience is relatively poor.
Through the NAS, we can open files directly in the shared disk area of ​​the network for editing, access, and even authors have NAS, animation, movies, when you want to see through the network to read the files in the NAS, look directly Film and watching movies are very convenient, and because of the high speed reading under the same LAN, the smoothness will not be discounted.
Third, more secure data storage, RAID multiple backup
Most people will back up data that they think need to be backed up and use less frequently used data on external hard drives, but they ignore the concept of multiple backups because we cannot put all eggs in the same basket because the risk is too high. Because of this idea, the concept of multiple backups that have been overlooked extends to the fact that I put the movie on the hard disk and I put the data on another hard disk for backup. This is also more secure. However, we do not know which hard drive will be damaged? Feeling is a choice of two options, the risk is still too high, and sometimes even put a hard disk will lose, the data is equal to half of the loss, management is not so convenient.
However, through NAS, we can solve this problem, because more than two slots of hard disk (2bay above) can do Raid backup, we can first do not have to control what kind of Raid, but the simplest description is to put more than two The hard disks are concatenated together, and the data storage space can be shared. You do not need to divide the video on the hard disk, the data on the hard disk, and throw it into the NAS and do Raid on it. Because some Raids allow one of the hard drives to crash, no matter which hard drive is broken, all the data will still exist. Just buy a new hard drive and make it back up. Let the NAS system fill up the gap for your hard drive. Can be solved!
External hard disk data storage space is dispersed, through NAS SHR technology, Raid technology, etc., can help your hard disk to do more space applications, not just the use of 1TB, 2TB external hard disk, but instead All the space is strung together. It is no longer because 10GB of A hard drive is left, 20GB of B hard drive is left, and then there is a 25GB file on hand. The problem of inaccessible access to additional external hard drives cannot be accessed. Through NAS, scattered data can be scattered. The combination of space allows you to buy hard disk space can be continuous, not because of external factors caused by the waste of space.
Fourth, easier cross-platform access: computers, mobile phones, tablets, televisions
With regard to access to the platform, I think that it is difficult for mobile phones to access external hard drives. Even U-disks are a problem. Although you can access them through other methods, you do not think that you need to go out and the phones may have to read. A mobile hard disk file or a U disk file, but also with a mobile hard disk or U disk out, it is very cumbersome, not in line with people's practicality. But now, through the NAS, you can even go home and access the home NAS's shared folder.
Then you may want to say, I will not set IP or something, so difficult, how can I come out? Take the author's NAS as an example. It has a Tcloud ID so that you can easily read and write home NAS data outside. If you want to have a private cloud and don't worry about public clouds, you can enable the Tcloud private cloud.
What about TV? If you can connect your home TV to the Internet, you can do different video and audio entertainment. Take TOS as an example. If your TV or mobile phone can install applications, you can install an ES file browser to access the movies created in your computer. Library. If the TV can only be networked or is a millet box, it can also use DLNA to directly read files in tandem with the NAS. Playing the NAS video on the TV directly is a very difficult place for external hard disks.
Having said this, NAS is reborn and is no longer a pure server or network shared hard drive, but a convenient device that goes beyond storage. With NAS, you can automate data collection and turn your private cloud on and off as you like without having to be restricted by free space.
Five, more outstanding applications: download machine, audio and video entertainment, photos, stand get
I think this should be the part that the external hard disk is unlikely to have. Because the external hard disk is only a hard disk, and the hard disk that can be accessed via USB, of course, the variability will not be like a small server like the NAS. widely. However, this is also an advantage of NAS, making storage more interesting. Let the stored data is no longer just the transmission of data, make good use of the spare parts of the hard disk to do other things. For the part that is most commonly used by the general public, I think it is "downloading."
Downloading BT/PT, downloading movies, music, etc. from high-definition stations is all about going to the computer and then shutting down to sleep, and the computer is an important data processing center. Doing a disk reorganization will make the data in the hard disk untidy and make the hard disk faster. If the computer hard disk hangs up, I think this will not only reinstall the system, but will not even provide information. It is actually not worth the candle. The emergence of NAS has improved this part because some NAS also have download capabilities.
Comparison of NAS and external hard disk:
Through some of the above comparisons, I believe that everyone knows more about the NAS, and learn that the NAS is not only a storage function, but also a convenient management interface for watching movies, downloading videos, listening to music, and grabbing files on mobile phones. Then I think you can prepare to lose a NAS.
External hard disk has its convenience, but in this era of mobile Internet, its activity has been gradually reduced. Previously, reports and manual assignments all people like to carry a mobile hard disk or U disk, but now everyone is accustomed to the Internet. The files were caught and the use of public clouds and private clouds was already around us. It was time for the external hard disk to retire.
NAS is a good choice for convenient, fast, and secure file access and backup. In addition to home use, NAS actually helps SMEs because NAS is an industrial machine. Designed for small and medium-sized enterprises, just because the Internet has developed rapidly, NAS has only begun to gradually serve home users.
