Ask for help with nas system for photography storage

Your question is too simple. For example, how much do you want to save? How long is it usually kept? Video-based or photo-based? Is it personal storage or studio storage? If there are photos in RAW format, do they need to be saved for a long time? . .

Another factor is your personal computer familiarity, because some NAS have good function introductions, but maintenance still requires a certain amount of knowledge.

I will give a simple answer here:

If your storage capacity is not large, for example, within a few TB, the lowest cost solution is to buy a raid hard disk box and plug it in. Two large-capacity hard drives take into account cost and reliability;

If the storage capacity is large, such as more than ten terabytes or more, it is recommended to use Synology's NAS, which is relatively stable, but the price is also very high ;

If you are familiar with computers, or have such friends, then building a NAS yourself will reduce the cost a lot.
