What is NAS network storage

NAS (Network Attached Storage) network storage realizes data transmission based on standard network protocol, and provides file sharing and data backup for computers with different operating systems such as windows / Linux / Mac OS in the network.

Network storage technologies realize data transmission based on standard network protocols and provide file sharing and data backup for computers with different operating systems such as windows / Linux / Mac OS in the network; Support 24-hour continuous power BT, FTP, HTTP, eMule and NZB download; As a multimedia center, it provides multimedia file streaming services for Sony Playstation3 / Microsoft Xbox / Apple iPad iPhone / Android mobile tablets; Provide http / ftp services for the construction of personal websites; Supports backup and restore of Apple IMAC / Mac Mini / Mac Pro / MacBook / Mac air (including black apple) and timemachine. Network storage structures are roughly divided into three types: Direct Attached Storage (DAS), network attached storage (NAS) and storage area network (SAN).

Advantages of NAS networked storage

NAS is a disk array connected by network cable. It has all the main characteristics of disk array: high capacity, high efficiency and high reliability.

1. NAS is easy and fast to install

2. Easy maintenance

3. Very good scalability

4. It has faster response speed and higher data bandwidth

5. Reducing the requirements for the server can greatly reduce the cost of the server, which is conducive to the popularization and application of high-performance storage system in a wider range

6. Support different operating system platforms

File sharing

File sharing (i.e. file server) is the most basic application of NAS. We can find a NAS network storage device in our network neighborhood and store public files in its shared directory. In addition, some NAS also have built-in file server function. We can access and manage files in NAS through the browser, and upload and download files in HTTP, which is as convenient as accessing the software download website.

Backup / disaster recovery

Another important feature of NAS network storage is backup / disaster recovery. Most NAS has a variety of backup functions, including local backup (backing up the data on the computer to NAS through LAN), remote backup (backing up the data on the remote computer to NAS through WAN), inter NAS backup (copying data between NAS and NAS), and so on. Some NAS also have the function of one click backup. Insert the USB storage device (such as flash disk and external hard disk) into the specific USB interface on the NAS, and press the Backup button to back up the files on the USB storage device to the NAS. In addition, NAS with two hard disk bits can build RAID 0 and RAID 1 systems. RAID 0 system has better disk performance and RAID 1 system has better security. NAS with 4 hard disk bits can form a more advanced RAID 5 system, which can not only ensure data security, but also improve disk performance.

network printing

Network printer sharing is also a common function for home users. Connect the ordinary printer with NAS through USB interface, turn on the network printer function of NAS network memory, and we can use this printer together in the LAN.

Photo sharing

As long as the photos and videos are stored in the specified directory of the NAS network storage, you can log in to the NAS web site through the browser for viewing, just like accessing the “local album”.

media server

After 2012, NAS network storage products for home and individual users generally have upnp-av function (or streaming media function), which can be found by windows MCE system, XBOX360, PS3 and other devices in the network. Multimedia files stored in NAS can be played without additional operation. This function turns NAS into a media server for various clients in the network.
