NAS vs SAN
https://www.slashroot.in/san-vs-nas-difference-between-storage-area-network-and-network-attached-storage
NAS is a device that has the sole purpose of storing your data. Unlike Server, it cannot do anything else. You cannot create AD on it. You cannot do virtualization on it. Nothing. You can only store files in the NAS which can be then accessed by the users on your network by FTP/Apple File Protocol/CFS/SMP etc. It is attached to your storage and stores the files for you. So, it is basically a file server.
NAS is just a box that attaches to your network and stores files.
SAN on the other hand is a Storage Area Network. You can have a cluster of storage devices together that will store your data. The advantage with SAN is that if you have a good replication or RAID strategy implemented, you won't lose your data unlike NAS, which is just a box of storage attached to your network.
The SAN gives you a feeling of local drive if connected with Fibre channel or iSCSI channel. You can install any software or save any file on SAN connected to your System and it will work like it's stored locally on your computer. The Safety of Data and fast speed is what makes a SAN great.
