At last, there is a Network Attached Storage device for small businesses and home offices that allows you to quickly and easily add capacity or swap out drives without down time. The automated RAID expansion is made possible by our patent pending X-RAID technology while hot swap support allows you to replace a disk without powering down the system. Leading performance is assured with our custom network storage microprocessor and a Gigabit Ethernet network port. ReadyNAS couples out of the box deployment and easy management with robust file serving and data redundancy.

My Summary: A NAS is just a filestore. It is just like a shared external hard drive. It is accessed as a shared drive and accessed like \\NAS-Server\folder1.
A SAN is also like that, but is accessed as a disk, and computers (servers) connecting to the SAN are allocated certain amounts of storage. They deal with the SAN as they would with a disk, in blocks. That allocation can change, so the storage is in a sense, virtualized. Computers have storage, and by expanding the SAN, you can allocate more space however you wish, to the computers accessing the SAN. So how do you access the SAN? iSCSI is one way - it just means using existing ethernet to access the SAN. It is lower performance and lower cost than alternate means. Fibre Channel is currently faster at around 4 GB/s. Duration : 0:8:26
