ANAS , or internet - Attached Storage , is atechnologyused to produce a storage twist that drug user can plug into to on the same LAN , or Local Area internet , to enter the dedicated store . This engineering science has been around since the 1990s , and now with storage devices being cheaper than ever , NAS setup are becoming more useful even for the middling user . In plus , with software solutionsfor creating a NAS becoming more available and approachable as well , people will be able to take more command of their datum .
Some users face up an issue while using a computing machine : the ever - present store job where they go out of quad on their desktop or laptop computer . In many causa , a user could only corrupt a raw hard drive or SSD and install it on their desktop to increase storage or buy an outside drive for a laptop computer . However , many computer case are remove dedicated hard parkway embayment , which induce adding higher amounts of storage more complex and tedious . With outside SSD or hard drives , well , that can be inconvenient since they are bulky and external , potentially taking up treasured desk space for the user .

This is where aNASshines . Suppose a user needs aton of international storageor wants an easy way of sharing data amongst family extremity on the same internet . In that causa , a NAS is the solution . Once a NAS is set up , the user can easily get at the machine over LAN by connecting to the NAS itself , essentially making the NAS a dedicated international memory drive , but without the hassle of needing to plug anything into the computing machine and also the welfare of adding more storage over time quickly . Any other user on the same LAN can also plug in to the NAS as long as they have permission to do so , which can be configured within the NAS software .
RAID Configurations And NAS Customization
Using a NAS for backing up data is a groovy use case as well . Within the NAS software system , TrueNAS , which isfree and subject - reservoir , a user can set up the NAS drives in various RAID ( Redundant Array of Independent Disks ) configurations to facilitate counteract data point corruption or storage thrust failures . The main welfare is that with different stage of RAID , the drives are supernumerary to different degree , which means that if one campaign fails , has data depravation , or any other driving way out , the data is lay in on the other driveway and wo n’t be lost . For exercise , a mirrored RAID layout with two 1 TB SSDs would only allow for 1 TB of memory board capacity instead of 2 TB , but the data point on the NAS would be stored as on each SSD . This give the highest amount of redundancy and makes the stash away data point more resilient to drive failure or data corruptness .
The user of course of study has as much customization as they want for their NAS . For deterrent example , a exploiter could opt not to use a RAID layout at all and employ the full storage capacitance of their drive . This is not recommended , however , since a important benefit of a NAS is data point redundancy . However , there are compromises for storage capacity and redundancy with different RAID form , which give the user higher computer memory capacity , but sacrifice the redundancy floor of mirrored setup without lose all redundancy . Overall , a NAS is the best resolution if someone has random storage drive lie around or needs a good way of life of sharing data on a local web . With free computer software such asTrueNAS , creating a NAS is mere and completely free to define up and can even be used to turn an erstwhile calculator into a unexampled storage equipment . Since a NAS does n’t take a good graphics calling card or even a super powerful computer , aNASgive users ways to bend their old hardware into something useful again .
