What is a NAS device?

A network-attached storage (NAS) device is a server that is dedicated to nothing more than file sharing. NAS does not provide any of the activities that a server in a server-centric system typically provides, such as email, authentication or file management. NAS allows more hard disk storage space to be added to a network that already utilizes servers without shutting them down for maintenance and upgrades. With a NAS device, storage is not an integral part of the server. Instead, in this storage-centric design, the server still handles all of the processing of data but a NAS device delivers the data to the user. A NAS device does not need to be located within the server but can exist anywhere in a LAN and can be made up of multiple networked NAS devices.

What is the speed of the network adapter available on a NAS device?

The speed is usually 1GB Ethernet connection but it can be changed to multiple Gb, 10Gb, fiber optic by adding a PCIe network card(s).
It depends on the NAS device. Most newer ones will have Gigabit ethernet, very cheap or old ones may only be 100Mbit and high end ones may have 2 separate gigabit ethernet connections.

What is the capacity range?

Depending on the type and volume of content you plan to store, there's a choice of capacities available all the way up to huge multiple TB (Terabyte) versions. A 160GB capacity for example would be enough storage for around 40,000 average audio tracks or up to 200 hours of video content. If you'll be using your NAS device to store masses of content, including High Definition content, or indeed backing up multiple user's PCs, you'll need a bigger capacity.

Network Attached Storage

...Network Attached Storage A “NAS” device, or network attached storage, is a computer that stores and shares files through a network instead of a hard cable. It shares files with other computers through the air the same way wi-fi sends an internet connection through the air. This method of file sharing is ideal for the workplace such as, corporate offices, small offices, or even small businesses like restaurants where mass storage needs to be shared between many computers. Here I will provide more specifics about network attached storage devices, such as communication speed, capacity, fault tolerance, and management capabilities. When dealing with communication speed we must look and the size of information being transferred. Typically, the regular communication speed is a 1 gigabit Ethernet connection but, this can be changed to multiple gigabit. It is hard to say what the max capacity of a network attached storage device is because there are many different adapters that can be used to add on more storage. After doing some research, the biggest set up I found was 72 terabytes. This was done using a 1 to 5 port replicator on a board with 6 SATA ports. Fault tolerance is important because it is how you set up your boards in case a drive fails. The raid 50 set up is one of the most common set ups but raid 10 is the most reliable. No management capabilities were found at this time. One question I was asked was what would be an advantage of all family photos and videos being......

(QuinStreet Enterprise , 2014) The speed of the network adapter on a NAS device can vary, depending on which one you buy. Your typical NAS device can run from 10 Mbps all the way to 1000 Mbps. The capacity range for a NAS device can range from a 1 TB all the way to 20 TB. This is 20,480 MB worth of data storage! With this large amount of data storage, you could store all your music, pictures, and videos in one device. (Best Buy, 2014) NAS Devices come with a built in fault tolerance called a RAID. RAID stands for “redundant array of independent disks”. With the help of RAID, you can tap into all of the storages on a NAS device all at once. A RAID array not only allows you to combine physical drives into a single storage unit, it also reserves a part of......

...TRINH NT1110 Unit 6 Research Paper 1 Network Attached Storage 1> Internet information on network-attached storage: * Definition: Network Attached Storage (NAS) is a dedicated hard drive which is set up with its own network address and provides file-level data storage services to other devices on the network. It allows both programming and files to be served faster because they are not competing for processor resources. NAS usually configured with a web browser and do not require a keyboard, mouse or monitor. Unlike other external hard drives, NAS has a processor. Some NAS devices will run using standard operating system like MS Windows, many other NAS devices use their own proprietary operating system. A NAS can store any data that appears in form of files, including email boxes, Web content, remote system backups, etc… Overall the use of a NAS parallels those traditional file servers. * NAS devices come in many varieties depending on you build it or purchase it from a vendor. The speed is usually 1GB Ethernet connection but it can be changed to multiple GB to 10GB, fiber optic by adding PCI-e network cards. * The capacity range also can be varied. If you have a port replication and add-on hardware drive controller cards, there really isn’t a limit on size. For example: if you have a board with 6 SATA ports which can be replicated (1 to 5 port) allowing 30 drives to be attached. Then if 3TB drives were used in RAID 50 that would be 72TB of storage......

A Network Attached Storage device is file level computer data storage connected to a computer network providing data access to a heterogeneous group of clients. NAS not only operates as a file server, but is specialized for this task either by its hardware, software, or configuration of those elements. NAS is often manufactured as a computer appliance a specialized computer built from the ground up for storing and serving files rather than simply a general purpose computer being used for the role.

...NT1110 July 31, 2013 Unit 6 Research Paper 1: Network Attached Storage A network-attached storage (NAS) device is a self-contained computer that is connected to a network. A NAS contains its own operating system that handles the function of data storage, file system, and the access to the files but doesn’t include a monitor, keyboard or other devices. NAS is dedicated for file sharing and allows more hard disk storage space and doesn’t need upgrades. The available speed of a NAS device varies but the usual speeds are 1 GB Ethernet connection however it can be changed to a multiple of GB and fiber optic by adding a PCIe network card(s). The capacity range also varies because there is no real limit to the NAS for example a board with six SATA ports can be replicated to allow thirty drives to be attached and up to 72TB of storage. There is fault tolerance (RAID) built into a NAS device if set up correctly RAID 50 is fairly stable, RAID 10 has been advertised as one of the best set ups because more drives can fail at one time without having data loss. A NAS device over all has its advantages it is great for file sharing and keeping all your files safe. So in a house where children and parents all have their own computer with pictures and videos it benefits them to have a NAS device where they can just store all those files and not worry about if one computer goes down all the files go along with the computer. http://technicallyeasy.net/2008/06/what-is-nas-device/......

...Jonathan Bowden October 27, 2014 NT1114 Unit 6 Research Paper Network Attached Storage A Network Attached Storage device is like having an at-home cloud. It allows all the computers in a household to access the same massive storage device. Since NAS devices start at 2 TB of data, they can hold everything your family is going to need. If a single computer gets damaged and you are using a NAS device, you don’t have to worry about all of your data being lost. The computer is broken, but all of your home videos and pictures are safe and sound on your NAS device. There really are no limits to Network Attached Storage. With 1 GB Ethernet you can transmit just about everything you want as fast as you’re going to need it. You could also use a 10GB fiber optic cable too if you really wanted to. I guess the only real limit would be on a wireless network where you would be limited to the speed of your wi-fi connection. The capacity range of a NAS device is really only limited to the size of hard drives. A board with six SATA ports can be replicated to allow for 30 drives to be attached, if 3 TB drives are used in RAID 50 that would be 72 TB of storage, or approximately 72,000 full length movies. So you are going to be able to put as much memory on the NAS device as you’re going to need. It will only be a matter of cost that will limit you. And since RAID is very stable, there’s nothing really to be afraid of using this kind of storage. As for whether or not a......

...Unit 6 Research Paper 1: Network Attached Storage (NAS) What is a NAS device? What is the speed of the network adapter available on a NAS device? What is the capacity range? Is there any fault tolerance (such as RAID) build into a NAS device? Are management features available? These are the questions I have to answer for this paper. So, here are my results starting with the first question. What is a NAS device? Network Attached Storage is a storage device connected to a network that allows storage and retrieval of data from a centralized location for authorized network users and heterogeneous clients. Seems to me that a NAS is like a WIFI version of an external hard drive. Though, if needing more room, you can add another to the one you already have. What is the speed of the network adapter available on a NAS device? NAS device doesn’t require much processing power. The largest bottleneck in performance will most likely be the network itself. Most home networks will use wired fast Ethernet (100 Megabits/sec), wired gigabit Ethernet (1000 Megabits/sec), wireless g (54 Megabits/sec), or wireless n (248 Megabits/second). What is the capacity range? Depending on the type and volume of content you plan to store, there's a choice of capacities available all the way up to huge multiple TB (Terabyte) versions.
