To choose a NAS for home use, it will require some of research on Google. There are many options and I can not speak for all of them, other than the one I actually purchased. No one can tell you which is the right for you without consulting with you first, but here is a short guide on what you need to think about before buying your NAS.

The most important thing is to understand your requirements before buying

Understand your requirements

1. How much data will you need to store. Synology has a really useful guide on how to choose the right synolgy product based on your specific needs.

2. How much money are you willing to spend

3. How much time are you willing to spend setting everything up and then custom fit. Some entry level models will do everything for you, others will allow for more customization.

4. If you are planing for a website, how many visitors are you expecting to have. Refer to the Synology NAS selector

5. Design your backup plan: How many copies do you need to have (we will talk about RAID later on)

6. How much online support will you need to set up and customize the unit. For this, it is better to buy a well-known popular model and brand as you will get a lot of support online. Here are some options: ReadyNAS by Netgear, Synology DS713+, QNAP TS-212 Turbo NAS
Here is the NAS I bought for my project:

The Synology DS713+ comes with all the cables and accessories needed, so the only thing left is to wait for the package to arrive home.

And the reasons why I bought this particular unit were:

I needed something relatively small that I could upgrade later on if my interest grew.
I dont have a lot of data, so 2x3TB is really an overkill, but I didnt want to upgrade too soon either.
I wanted a vendor that was popular so I could troubleshoot and set up by researching the net, as I knew that there will be tons of forums and people willing to help me out.
I saw demonstrations online of the Synology DSM (their user interface) and it looked easy to use, but still possible to tweak with no major knowledge.
and I really wanted the out-of-the-box functionality: cloud service, photo albums, apps, wordpress. It was perfect for me
With all this said,

There is no perfect choice of NAS for everybody, you have to decide what is important to you and then choose the vendor
