On the computer , data storgage  is important to photographers and cenimagrapher  as cameras . If you serious for save and secure all your data in one storage – you will need NAS solution .

So What is NAS ? – NAS is storage system base on the network and only allows the system to store data through the network . NAS devices have cost investment very lows but demonstration outstanding feature : performance, flexibility and high availability.

Function of NAS  :

  1. Plenty of storage space

    The biggest advantage of using old parts to create a new device is that you can add as many external drives as you have ports on your motherboard (and space for in your enclosure). This will give you a much greater storage capacity than if you’re using a simple router and external drive.

  2. Create a RAID array

    Having more space for storage devices also means that you’ve got the tools to create a RAID array – a means of using additional disks to keep mirrored copies of the data on your primary hard disk drive(s). This is an excellent way of keeping your data safe, and restoring files should an HDD fail.

  3. High end performance for a low price

    It’s easy to get ahold of previous generation computer parts these days – whether you buy them online through sites like Craigslist or eBay, get them at thrift stores and garage sales, or simply make use of an old computer lying around at home.

    As older processors, motherboards, and other essential NAS components are replaced with newer versions, the outdated tech doesn’t lose its value for basic tasks like data storage – and it gets a lot cheaper.  For example, an Intel Pentium E5500 CPU, released in 2010, can be snapped up on Amazon for just $35, while its 2015 successor the Intel Pentium G4400 will cost at least double. While differences in technology between the two models might be significant to those looking to build a top of the range PC, for the purposes of creating a NAS, they’re very much the same product.

  4.  

    Very customizable

    Both with hardware and software, taking the the from-scratch approach when you build your own NAS will let you create a device that meets your exact specifications. Not only can you decide how many drives you want to use, and how your NAS interacts with other network devices, but being able to choose from multiple operating systems lets you decide exactly what your NAS will do, and how it will do it.

  5. You’ll need some technical know-how

    Although of course it’s never too late to learn, if you’re not confident figuring out some technical jargon, this might not be the best solution for you. Even experts make mistakes, so it’ll help if you’re ready to roll with the punches and know how to salvage things if something goes a bit wrong. On the plus side, it’s nowhere near as hard as it looks – you just need a little faith!

  6. A NAS enclosure

    A NAS enclosure is, essentially, the box that your motherboard and drives will sit inside. Technically, you can make it from pretty much anything you like, so long as it protects the tech – but an old computer casing is probably the quickest and easiest way to go – and will cost you next to nothing.

    If money isn’t an issue, then you might also want to consider a Micro-ATX or Mini-ITX case, for something a bit more high-end. You can find them on Amazon, of course, as well as on computer parts sites like Newegg and PCPartPicker.

  7. A motherboard

    A motherboard is one of the most crucial components of any DIY NAS, so it’s worth spending some time to make sure that you find one that works for you. You won’t need anything fancy, but you will want to ensure that it a) fits comfortably within your chosen NAS enclosure, and b) is compatible with all of your other components, or you’ll be making a lot of extra work for yourself further down the line!

    For maximum options when it comes to data redundancy and storage capacity, we’d recommend choosing a motherboard with at least 6 SATA ports, to ensure that you won’t run out of ports to connect your hard drives to. Important features like the ability to boot from USB can be found in most modern versions, although older models might not offer them – so check the manufacturer’s website for more details before handing over your money.

  8. A CPU

    A CPU (also referred to as a processor) doesn’t need to be the latest model, and you’ll save a lot of money by using a previous generation model. Sticking with entry-level Intel or AMD models should set you up just fine, as you won’t need a lot of processing power to run your NAS system. You’ll also need to purchase a cooling system to prevent your CPU from overheating.

  9. RAM

    Once again, you don’t need to worry about getting anything top of the range when it comes to RAM. As a rule of thumb, NAS OS provider FreeNAS recommends purchasing 1GB of RAM for every TB of raw storage space you’re planning to use – although you shouldn’t encounter too many problems if you fall a little short. For a home setup, 2GB is usually a good place to start.

  10. Hard Disk Drives

    When you build your own NAS device, there are two different ways of approaching the search for hard-disk drives (HDDs) – buying one or two drives with the biggest storage capacity you can afford, or buying multiple, smaller drives to use in a redundant array.

    For example, while buying a single 12TB hard disk might give you more space for less money, it means that all of your data will be stored in one place – leaving it entirely vulnerable and much more difficult to retrieve should that hard disk fail.

    Alternatively, spreading your data across eg. one 4GB and four 2TB HDDs will mean that you’re not constantly relying on the performance of one disk. It also gives you space to set up a RAID array for redundant copies of your data that you can draw upon should your primary sources of storage be compromised – an essential part of keeping your stored files secure.

  11. Extra stuff

    You’ll need a few extra parts to get things up and running when you start to build your own NAS – namely a power supply and a few extra SATA cables. Although some enclosures come with power supplies included, many don’t, so it’s well worth checking in advance. You won’t need a lot of power to run your network storage device (it’s unlikely to ever have a draw of over 100 watts), but it’s worth choosing a make, like Seasonic or Antec, that you know will be reliable.

    Similarly, many motherboards will only be sold with a few SATA cables – leaving you short if you want to include several drives in your NAS build. Buying some extras in advance won’t break the bank, and should save you some trouble when you start building your NAS system.

  12. An operating system

    In order to give your DIY NAS a functional operating system, you’ll need to download a program to do the legwork for you. There are several different software providers that you can use to do this – some of the most widely-used being FreeNAS, Amahi, and NAS4Free.

Conclusion

Building your own DIY NAS from an old PC is an excellent way to get advanced features and plenty of storage space without paying out for a brand name. It’s also the best way to create precisely the NAS system you want, without compromising on detail.
