Pros: The Buffalo NAS is fast, quiet, has a small footprint, and a large cache(512MB). Once you have it working, you can forget about. It is just there anytime you want to access it.

Cons: Documentation could be better. I have given an overall description below of how this NAS is works.

Overall Review: You can choose to configure this NAS in one of several ways. I chose to configure it as a RAID 1. I did this because I have several thousand photographs that I want to protect and share, and as a RAID 1 array, I have complete backup in case of a drive failure. You will create an IP address on the NAS for your local network, then you must configure your router to forward uPnP port 9000 to get on the internet. After you get the NAS on the internet, you can go to Buffalo's web site and create an id. for your NAS. Once this is done, you can go to your Apple or Android store and download a free ap. for your remote device and you are done. You can configure the NAS to only allow RO, RW, etc. any of your pictures, music, or documents you wish to share. I am a retired network engineer and I would recommend you either have some computer networking experience or know a friend who does to insure a successful installation.

I sent the correct HP ENVY model number (15t-j100), the picture was correct, the fan delivered after waiting 2 weeks was not like the picture and is useless.
