NAS is network attached storage. Simply put, it is a device that is connected to the network and has data storage and access functions. It is also called network storage. Its main function is to allow users to store, back up and share each other's data. It can also transfer file data to multiple computers without additional hard disks.
Compared with enterprise-level NAS, the positioning of civil-level NAS is more targeted. Major NAS brands have launched many simple and easy-to-use NAS products for the diversified needs of ordinary users. We often just need to install the hard disk, plug in the network cable, and then make simple settings to get started. The use requirements of home NAS are relatively simple, which is nothing more than storing and sharing files at any time through the network to ensure the safety of files and data; Advanced users can also use NAS to build audio-visual entertainment and network servers. Personally, I like NAS's convenient storage, sharing and backup functions, practical network services and audio-visual entertainment functions, and I can't put it down after using it.
I use the NAS products of William Unicom and Qunhui, and their common characteristics are high playability and strong expansibility. However, the configuration and control of these two brands' NAS systems are complicated, which is quite unfriendly to novice players. Is there a simple NAS that meets the needs of most users? Yes, I recommend Lenovo Personal Cloud T2.
The biggest difference between Lenovo Personal Cloud T2 and NAS products such as Qunhui and Wei Long Unicom lies in the system. Although the NAS system of Lenovo Personal Cloud T2 is not as playable as these two brands, its functions can basically meet the needs of most users, and the system interface is simple and easy to understand, which is very suitable for novice players to enter and exit NAS.
Lenovo Personal Cloud T2 looks younger and more fashionable than traditional NAS products. In this era of justice, its fashionable and simple design can better cater to the preferences of young users.
Lenovo Personal Cloud T2 is a dual-disk design, which is compatible with 3.5-inch and 2.5-inch hard disks, supports up to 36TB, and supports RAID 1 mode. Two hard disks can be used to form a disk array, and each file to be stored can be synchronously stored in the main hard disk and the mirror hard disk. Once the main hard disk fails, the mirror hard disk can be replaced immediately, so as to keep the NAS service uninterrupted and ensure the data security.
As a NAS product, Lenovo Personal Cloud T2 has basic NAS functions such as storage, backup, sharing, online download anytime and anywhere, and my favorite function is automatic backup. Using the automatic backup function in the mobile APP, you can automatically back up your mobile photo album, save the storage space of your mobile phone and prevent photos from being deleted by mistake. At the same time, whether it is Android phone, Apple phone, Windows system or MacOS system, files can be easily transferred across devices and systems through backup function, which is simply the gospel of a multi-device user like me.
As mentioned above, Lenovo Personal Cloud T2 is playable compared with the shortcomings of traditional NAS, and it does not have as rich system services and software ecology as Qunhui and William Unicom. There are only three practical third-party Applications built into the app side of Lenovo Personal Cloud T2: Baidu network disk, Dapeng speed-up and plaything download.
Baidu network disk: bind Baidu network disk account to realize file transfer between network disk and Lenovo Personal Cloud T2.
Dapeng Speed-up: It is not cheap to speed up the existing telecom or Unicom broadband. For example, the cost of upgrading Unicom from 200M to 300M is 192 yuan/year.
Toy download: a third-party download tool supporting HTTP, magnetic link, FTP, BT and Thunder Seed.
Being able to transfer files with Baidu network disk can solve the speed limit problem of many users' network disks, but the mutual transfer speed is only about 100KB/s, and the transfer speed of small files is comparable to that of ordinary users using Baidu network disk. Fortunately, the advantages of transmitting large files are obvious, even if the computer is turned off, it can run 7*24 hours.
Although there are many differences in appearance and system, there is something in common between traditional NAS (such as Qunhui and William Unicom) and younger products (such as Lenovo Personal Cloud T2), and that is hard disk. The hard disk used by NAS has faster transmission speed, longer service life and higher stability than ordinary hard disks.
After weighing the performance and cost performance, I chose the mainstream western digital red disk with a capacity of 4+ 12TB. You are not mistaken, just a hot large-capacity hard disk at this stage.
My 12TB western digital red disk is a regular version with a large capacity. If you don't have such a big storage demand, I suggest buying a version above 4TB. Western Digital Red Disk Plus adopts CMR vertical architecture, which has better performance and faster RAID reconfiguration ability, and can meet the work needs of small and medium-sized enterprises in NAS environment. Home NAS is more than enough for Western Digital Red Disk Plus.
The adoption of NASWare 3.0 technology in the Western Digital Red Disk can effectively improve the storage performance of NAS and greatly reduce the common hard disk problems such as stability, power consumption and noise in NAS systems. NASWare 3.0 technology can shut down the running command after it is executed in case of sudden power failure, so as to minimize data damage or loss.
After all, it is a mechanical hard disk, which works 24 hours a day, and you must have a good shock absorption strategy. Western Digital Red Disk adopts 3D active balance enhancement technology and RAFF technology to enhance the vibration protection of hard disk. At the same time, the StableTrac tracking technology is adopted to reduce the vibration caused by the system, stabilize the CD and ensure the accuracy of the reading and writing process.
Have you ever had such an experience when using the network disk? Obviously, the download speed of 100M and 200M broadband is only 100KB/s/s, even for paying VIP members, the download speed is still not ideal, and the speed limit has become one of the most important factors limiting the development of network disk.
In the same network environment (200M Unicom broadband), Lenovo Personal Cloud T2 has a download speed of about 1 10MB/s, an upload speed of about 45MB/s, and an external network download speed of about 15MB/s; And I use Baidu's network disk to download files at a speed of about 200KB/s, and the download speeds of the two are simply worlds apart.
Under normal circumstances, the sequential reading and writing speed of the western data red disk is about150mb/s. When I use the external USB 3.0 interface of Lenovo Personal Cloud T2 to transfer files between them, the transfer speed can reach about 90MB/s, which is quite impressive.
Under the background of the Internet of Everything, the arrival of the 5G era will inevitably affect our usual network usage habits. Wireless transmission will become one of the most important and convenient transmission means between users and devices, and devices and users, followed by the traditional mobile storage devices being gradually replaced by network storage devices such as NAS.
At present, under the premise of basically the same basic functions, hard disk has become a key link affecting the use of NAS. Western Digital Red Disk is a hard disk that I have been using since NAS into the pit. Its transmission performance, stability and other experiences have made me quite satisfied. Several hard disks hung on NAS for high-frequency use have been used for more than three years, ranging from one year, without any problems.
The above is all the contents of this sharing. Small partners who want to play NAS can buy it on demand. What I want to toss is Qunhui and William Unicom. If you want to enjoy the convenience brought by NAS quietly, choose an easy-to-use NAS, such as Lenovo Personal Cloud T2. As for the hard disk, I still recommend the Western Digital Red Disk with high price.
