Without the model it’s hard to help you.
It would be best to give us the model, then we will see if this is a sfp or sfp+ port. With sfp you are still limited to 1G. And even if it’s sfp+ and you connect your nas to it, the user is limited to 1G from the rj45 ports on the switch. So unless there are multiple users using an exzessive amount of bandwidth this will not help you at all.
Just for your information. You need a Gbic which is supported by you switch. This gbic can be with fiber (single or multimode LC) or also RJ45 1G or 10G. There are a lot of options.
