6 Reasons to tell you why you need a NAS

When the computer hard disk is full, most users of the first idea is to buy a few terabytes of hard disk to expand, if it is a power user, the first thought is to buy an external hard disk to back up the data, the idea is not wrong, that is when you do not know "nas" this good thing, will think so. If you know the NAS This private network storage server, perhaps you will change your thoughts and thinking, so that the sharing of files, share can be more convenient, but also in mobile devices, cross-platform access, not a very convenient thing?
For Nas, the majority of users still do not understand exactly what is the thing? Even some people may be because they do not understand, unclear and resist to understand the new things, want to say in the simplest way to do data backup, expand the hard disk is good, but this is not a permanent, assuming that the hard disk suddenly broken, bad, data no additional backup, how to do? Can you get the information back? Do you think there is enough data protection for only one hard drive? If it is a record of your full memory or important documents, I think this is not worth the candle.
Previously, the author is also accustomed to purchase external hard disk as a data backup, but for a long time, I believe we all have the same problem, why did not respond? Why do you want me to format it? Why does the socket seem to be broken? Why do you connect and disconnect? This should be the majority of users using external hard disk will encounter the situation, and sometimes the problem of USB transmission line, sometimes your hard drive is broken, and once the hard drive is broken, I think a lot of people should only send a friend Circle punch card to say that their hard drive is bad, because the recovery of data is expensive, repair hard drive also trouble, Even the odds of success are very low.
Is there any other more recommended way to protect the data? In fact, with the development of the public cloud, the private cloud is also becoming popular, and even some people will be through some obsolete computer refurbishment, install some software to make him into an ultra-low-cost NAS. Although this is a good choice, but the technical threshold is a bit high, you have to brush the BIOS, re-irrigation, installation, for the novice, this is not the most convenient solution, because as a user of us, is to be simple, fast, convenient, too cumbersome procedures will let us return to the most original backup method.
What is Nas, in fact, NAS (Network attached Storage: networked secondary storage), is a small drive server, is also a small computer, in the home connected to the network, you can read and write to the NAS server data, But you don't want to think of NAS as a server like that, most Nas is very beautiful in appearance, such as.

Terra Master (terramaster) F2-nas 2

Now many people will drop the data to Baidu Cloud, Kingsoft, icloud and other cloud disk, this is to upload the information to the public cloud. And if we drop the data on the NAS, we throw it into the private cloud because this NAS is in your home and it's a small server you built yourself. But with so much to say, you may not be able to understand the difference between NAS and external hard drives, and even some people may not know exactly where the NAS is. Why do I have to spend more money to buy a small computer, I use my own computer is not good? In fact, you buy more than a small computer, server, you buy a private cloud, more convenient access, richer resource sharing, more powerful data backup, so that you value a small investment.

One, more convenient data sharing access and Rights management

In the past, the company's file exchange can be said to be very troublesome, departments and departments to exchange information, you have to use the mobile hard disk, copy to cuff, colleague a first copied the data to the computer, then you copy the files you want, and sometimes even ask colleagues to put the hard drive to the computer, and then open a shared magnetic area, so you go But sometimes he accidentally shut off the computer, you have not finished, become you will not be able to access data, the use of very troublesome. The above predicament you may not have encountered, but in fact, similar things happen every day, although the mobile hard disk read and write speed is not slow, but for multi-person data access is not so easy, have to exchange rotation use, or a computer as a shared settings, very inconvenient. If there are several people in the office, at home, who want to access the same hard drive, then they have to queue up and take the files in turn, resulting in wasted time and inconvenience.
Traditional mobile hard disk, data to access must be connected to the USB cable, and even some of the USB power is not enough, to get an additional AC transformer, to allow the external drive to rotate, and external hard drive if the collision, fall, may cause data read and write problems. Because the external drive is not fixed in-place device, but can let you take a walk around. Hard disk is the most afraid of collisions, but also to make it in such a dangerous environment, the security of information is very worrying.
But now, you can use the NAS to directly insert the hard disk into the NAS fixed, only need to put the data in the NAS, through the network shared disk, even if the same computer shut down (NAS standby), you can still be able to capture data through the NAS, The disk can also be managed and restricted according to the user's privileges. The power consumption of a NAS is also lower than that of the general computer, long-term standby, in fact, there is not much need to worry about electricity tariffs, because it is about 10 more than W, compared to the computer turned on hundreds of W, very power-saving.

Second, faster processing speed, hardware equipment upgrade

Speaking of hardware equipment, have to mention the external hard disk most of my helpless place, the author bought two external hard disk, the result because of the long-time use, USB Plug and unplug, resulting in the interface will be a bit of the status of the line, some USB transmission line may not be able to read, or even appear formatted? And this situation, of course, I will not be easy to go down (but someone will go to point), once the information is gone. This situation also occurred in the author's acquaintance, because the elderly sometimes think plug to be plugged in, so in the connection of the transmission line of the external drive, hard disk and transmission line part will be very hard to push it to pick up, over time, resulting in external hard drive socket inside concave, the results sent to the original said no way to deal with, The past life photo record, it is all gone, so he is very heart, although the hard drive is willing to give him a new, but this kind of things will not be full of memories.
The use of external hard disk is afraid of it because of shaking bad rail, transmission line and transmission port between the poor, resulting in irreparable problems, if the hard drive well like the general computer, connected to the computer, do not move it, but will not let the interface caused by consumption, and will not be unable to read the problem. In addition, because the early are USB2.0 transmission line, even if it is USB3.0, but the speed is not comparable to gigabit network transmission and data access, the speed of a drop in the data transmission Sisu access hard disk is not suitable for anytime access, edit at any time, because as long as a line to move, may interrupt the connection, The convenience is relatively poor.
Through the NAS, we can directly in the network shared disk area to open the file, for editing, access, and even the author of the animation, the movie exists Nas, want to see through the network share to read the files in the NAS, directly watching movies, watching movies, convenience is very sufficient, and because the same LAN under the high speed reading, Smoothness will not be discounted.

Three, more secure data storage, RAID multiple backups

     the General people think that need to backup data, infrequently used data back to the external hard disk, but ignored the concept of multi-backup, Because we can't put all the eggs in the same basket because the risk is too high. Because of this idea, the neglected multi-backup concept extends, I put the video on the hard drive, I put the data on another hard disk to do backup, so it is more reassuring. But we don't know which hard drive will be damaged? Feeling is the choice of two choices, the risk is too high, and sometimes put a put even the hard drive lost, the data is equal to the loss of half, management is not so convenient.
However, through the NAS, we can solve this problem, because two or more slots in the hard disk (2bay or more) can do raid backup, we can first do not have to control raid what kind of, but the simplest is to put more than two hard disks connected together, data storage space you can share, You do not need to sub-film in a hard drive, data on the B hard drive, all thrown into the NAS and do raid on it. Because some raid allows to break one of the hard drives, regardless of which drive is broken, all the data will still exist, just buy a new hard drive back, let the NAS system for your hard drive back to that vacancy, you can solve it!
External hard disk data storage space is scattered, through the NAS's SHR technology, RAID technology and so on, can help your hard disk to do more space applications, not just 1TB, 2TB external hard disk use, but the space is all strung up, no longer because a hard disk left 10GB, b HDD left 20GB, and then have a 25GB file, unable to access caused by the additional purchase of external hard drive problem, through the NAS can be scattered space together, so that you buy the hard disk space can be continuous, not because of external factors resulting in wasted space.
The author uses terra master (terramaster) F4-nas, this can be connected to four hard drives, the author will be two of them 4TB hard disk Raid1 backup, the remaining one 2TB hard disk using the release mechanism of not to do backup, it as a NAS in the download of the dedicated hard disk, Does not affect the main data backup, simply said that the remaining 2TB this hard disk for a long time to download read and write, even if it is broken, it does not affect my other two 4TB data, assuming that one of the 4TB hard disk is broken, I just buy a 4TB hard drive back, do data reconstruction, can also be 4TB those two hard disk storage of data to complete rescue back. The ratio of the hard disk to use, can easily through the management interface operation and settings.

Four, more user-friendly TOS operating system

The traditional external hard disk, just file storage, and can not do the correct data classification, or more use of hard disk, but NAS changed the hard disk is only the role of storage disk, in Terra Master, for example, developed a dedicated NAS to use the management interface "tos", so that the NAS becomes better use, Let the hard disk is no longer just hard disk, through the management of the TOS, you can more easily see the condition of the hard disk, the system can do more settings, including the above mentioned permission settings, according to different users to provide different access permissions, different shared folders.

Five, easier cross-platform access: PC, mobile, tablet, TV

About the platform access, I think the phone to access the external drive has a certain degree of difficulty, even the U disk is a problem, although you can access through other means, but you do not feel out of the house, mobile phone may want to read a mobile hard disk file or a U disk file, but also with a mobile hard disk or USB flash drive out, Seems very cumbersome and not easy to meet the practicality of people. But now through the NAS, you can access the shared folder in your home Nas.
Then you may want to say, I do not set IP what, so difficult, how can I connect out? In fact, Terra Master has a Tcloud ID that allows you to easily read and write data from your home NAS. If you want to have a private cloud and don't trust the public cloud, you can enable the Tcloud private cloud. What about the TV? Home TV If you can connect to the network, you can do different audio and video entertainment, in the case of TOS, if the TV or mobile phone can install an application, you can install an ES file browser, you can access the computer built in the movie library. If the TV can only be networked or millet box can also be changed through DLNA and NAS directly connected to read files, on the TV directly dial the NAS's audio and video, which is difficult to do external hard to do. In this case, the NAS has been reborn, no longer a simple server, network shared hard disk, but a cross-out of storage convenience devices. With Nas, you can automate your data and turn your private cloud on and off as you want, without having to be confined to free space.

Six, more outstanding applications: Download machine, video entertainment, photos, racks are all done

I think this should be the part that the external hard drive is not likely to have, because the external drive is just a hard disk, can be accessed through a USB drive, the variability of course will not be like a NAS such a small server so extensive. However, this is also an advantage of NAS, which makes storage more interesting. Let the storage data no longer just the transmission of data, make good use of the spare parts of the hard drive to do other things. To the most commonly used parts of the general public, I think it is "download".
Normal download bt/pt, download HD station above the film, music and so on, are to computer mount, and then can not shut down to sleep, and the computer is an important data processing center, long-time reading and writing, if not a good disk reorganization, will let the data scattered in the hard disk, make the hard disk consumption faster, if the computer hard disk hung off , I think this not only to re-install the system, even the data are not, it is not worth the candle. The advent of NAS has improved this part because some NAS also has the ability to download.
In Terra Master (terramaster), downloading is a very handy feature that can download BT, download pt, offline thunderbolt, and make it easier for you to download. Have downloaded BT and PT friends, should know that BT download is a long time hard disk read, will speed up the use of hard disk life, we do not have to deliver these things to the NAS do it, to the NAS, the computer can be safely shut down every night, the operation of the NAS power is much more than the computer, if afraid of the impact of hard disk can use NAS dedicated WD, which is dedicated to the NAS 7x24 work hard drive, the service life and stability greatly improved, but also like the author of the download dedicated folder on a hard disk (do not do raid), the important information stored in B hard disk (also do Raid1), the data and download separate, unaffected , so that the NAS can not only secure the storage of data, but also can be safely downloaded, non-impact.
In addition to downloading, NAS can also set up a server, setting up a forum, when the DNS server and other functions, before a friend of the NAS as a Web server to use, their own server tube, in addition to do more business use, cross-NAS machine backup, and some NAS also built-in virtual machines, The NAS is no longer just a NAS, but a multi-functional server, and more applications can refer to the official introduction (www.terra-master.com).

Nas vs. external drives comparison conclusion:

Through some of the above comparisons, I believe you can know a little more about Nas, knowing that NAS is not just a storage function, but also can see movies, download movies, listen to music, mobile capture files and a very convenient management interface, then I think you may be ready to prodigal a NAS. External hard disk has its convenience, but in this era of mobile Internet, its active level has gradually reduced, before the report, handed homework everyone likes to carry a mobile hard disk or a U disk, but now everyone is accustomed to through the network to seize the file, the public cloud, the use of private clouds around us, It's time to retire the external drive.
To have convenient, fast, secure file access and backup, Nas is a good choice, in addition to home use, in fact, Nas for small and medium-sized enterprises to help more, because the NAS itself is an industrial machine, is designed for small and medium enterprises, but because of the rapid development of the Internet, The NAS is starting to gradually target home users.
For the NAS starter can start from 2, if not too much budget can start from 1, of course, personally feel that 2 is the most convenient, if you want to secure data backup and download, then 4 disk will be a new choice, two hard disk groups Raid1 backup, the remaining two hard disk can not backup, One to do the download and access, one to do the general use of data access, effective use of the hard disk in the NAS, so that you more efficient work and entertainment, Nas is not just storage devices, but storage, work, entertainment and a private cloud center!
