Basically, the main difference is that the TZ series is intended for a Branch office since it has fewer ports and the speed is around 1 GB.
The NSA series has more processor power and more port where you can create subnets and zones (like DMZ). Also, it has ports with 10 Gb and a processor to support the demand.
I have read that an approximate number of users in the highest TZ series (TZ 670) is around 150 to 200 but that is just an estimate.
Hope this helps. You can get more details in SonicWall datasheets where you will find the speed, throughput and more technical specifications to select the one that fits your requirements.
In simple words,
TZ is for small businesses (less than 100, maximum 150 users).
TZ has fewer ports.
NSA is for medium and large enterprises: > 150 Users,
NSA has many ports to support large networks
