A NAS (Network Attached Storage) server provides allows multiple computers to store files that are located on the same network. In return, the NAS server makes it easier to send and share files with other computers on the network, and provides greater security and memory space than most traditional external drives. Files on a NAS device can also be accessed from a web browser in case the user is not in the same location as the NAS server itself. NAS units are void of many of the applications and services that other servers typically offer. As a result, a NAS server is less susceptible to possible viruses and system crashes. There are different types of NAS systems to consider before installation, as well as certain provisions to follow when installing the device. As long as the appropriate NAS device is chosen and installed correctly, there will be many advantages to gain from having this type of server in one’s home. How a NAS Server Works Inside a NAS device are several hard disks that store data, which is classified under the RAID (redundant array of independent disk) operating method. By using RAID, files are stored in a number of different places on various hard disks. NAS is considered to be a client/server design, meant to share files easily between users on a particular network. The actual unit itself is known as a NAS box or NAS head, which links the NAS server to all users on the network. Unlike a computer the NAS device does not need a monitor, mouse, or keyboard to operate, and is instead run through a web browser. In order to operate, the NAS device is hooked up by an Ethernet cable. This gives the unit the ability to connect with various browsers with specific network addresses. The communication is done over a TCP/IP (Transmission Control Protocol/Internet Protocol), which is simply the language used by computers to communicate with one another. Typically there are additional protocols used to transfer information, which are built on top of the TCP/IP. Common protocols include NFS (Sun Network File System) and CIFS (Common Internet File System). Many NAS servers also support HTTP (Hypertext Transfer Protocol), which allows users to download files into a web browser if needed. Choosing an NAS Server Before installing a NAS server, it is important to consider which device would work best in the home. Factors to consider include the server’s intended purpose, how many computers will require access to it, and how much memory capacity it will need in order to store the users’ files. There are a few options to choose from when selecting the right NAS device. Some come with all the bells and whistles included, meaning the NAS device comes installed with all HDDs so that the storage system is ready to go. These types of NAS servers are usually more expensive. Another option would be to purchase a NAS server without an HDD installed, so users will have to install this on their own. Although this requires more effort, the user can install the exact HDD desired into the NAS device. How to Install a NAS Server Installing a NAS server is not a particularly difficult task, even for those unfamiliar with the process. Many systems will require users to download software particular to the NAS unit, which will help computers connect and share files with the device. Often the installed software will also assist in backing up files from the computer to the NAS server, which is a very helpful tool when it comes to saving data. When beginning the setup process, most systems have wizards that will walk the user through each step. Prior to installation, users should be prepared to determine their backup options, the type of RAID configuration, who will have access to the NAS server, permission levels for each user, and what types of files will be shared. Generally users will want to set up an account for every individual who has access to the server. Folders and permission levels can be created for each individual separately. Installing a NAS Server on a Windows PC Operating System If a Windows PC operating system is being used, the NAS server should automatically appear in the Network Places folder once the initial setup process is complete. If it does not, users will have to map out this step on their own. This can be done through the Tools drive on My Computer, under the Map Network Drive select. Here one can pick any empty letter that appears with an available free drive, but users should avoid one that was used previously. The user will also have the option to link the NAS server as just a one-time user, or on a permanent basis. Once this is done, access is provided to the NAS server. Installing a NAS Server on a Macintosh Operating System If a Macintosh operating system is being used, many of the same systems are in place to set up and install the NAS server. Most systems will have wizards to walk users through the process of sharing folders, adding users, and setting permission levels for each individual user as well. Once the NAS device has been installed, it should automatically be loaded into the Finder’s list of shared folders. If it does not appear right away, the user can type in the IP address of the installed server to access the shared files. Pros and Cons of a NAS Server Although a NAS server brings many advantages to its user, there are some disadvantages to consider when deciding if a NAS device is the right choice for storing data. It is important to factor in both the pros and cons before making a purchase. Pros of a NAS Server NAS servers have the ability to store documents, digital photographs, music, and other important types of files that can be found on a computer. One of the main advantages of having a NAS server installed in the home is that anyone who can connect to the network has access to shared files anytime and from anywhere. The only thing necessary to access the server is an internet browser, which in today’s world can easily be found on a desktop computer, laptop, smartphone, iPad, or other form of modern technology. Without a NAS server, many networks will not share files if the computer holding the files is not turned on. Using a NAS server also eliminates the need to store all data on a computer’s hard drive, thus freeing up space and speeding up the operating system. The server will also have the ability to back up data, which can be done manually or automatically depending on how it is set up. Backing up files can be vital during a system crash. The NAS backup will prevent the loss of everything stored on the computer itself. Typically NAS servers will have a memory capacity of anywhere from 500 GB to 7.5 TB, the latter of which is a very large amount of space. For example, 1 TB of memory could store 200,000 photos, 250,000 MP3 files, or 120 movies. Cons to a NAS Server Disadvantages of a NAS device do exist, though there are not many. In general NAS devices are more expensive than a common external hard drive with the same memory capacity, and NAS servers take more time and effort to install. At times it can be difficult to get the NAS server to correctly connect to the computer as well, and some may not be DLNA certified. Lastly, most Windows users should automatically be able to access all computer hard drives located on the same network without the need for an added device to assist with this function. Find NAS Servers on eBay Now that you understand what to look for in a NAS server, you can begin your search for the perfect model to fit your home. In order to meet your individual needs, eBay will be able to provide numerous options when it comes to different NAS devices. You can start by running a keyword search. Simply type specific keywords into the search bar on the eBay homepage. For example, type NAS server into the search box and all available products will appear for you instantly. You can be as specific as you would like. If you are looking for an Apple Time Capsule for your Macintosh computer, simply type that into the search box and only available options for this specific product will appear. Another option is to browse through eBay’s categories. To search for NAS servers this way, go to Electronics, and then Computer / Tablets and Networking. NAS devices can be found under multiple subcategories, including Drives, Storage and Blank Media, and Enterprise Networking, Servers. Conclusion There are many reasons why a NAS server would be a helpful device to add to a home computer network. Sharing files with anyone who has network access is easy and convenient. Users can share anything from family photographs to important documents. Much larger amounts of data can also be stored on one network, which helps simplify and organize a home’s wealth of data. With a relatively easy setup and operation, a NAS server is a great solution for anyone needing additional storage space for large amounts of data.
