Do you want to store your business documents on a NAS? A NAS for business use has at least 2 bays, so space for 2 hard drives or more. This gives you the option to save data in RAID, making it more secure. We recommend a NAS with 2 bays for independent entrepreneurs who work alone. Choose 3 or 4 bays and 1GB RAM when you use the NAS in a small office for up to 15 people. For a medium-sized company of 15 to 30 people, we recommend a NAS with 4 to 8 bays and 4GB of RAM. For larger offices, you should choose more than 8 bays and at least 8GB RAM that can be expanded.
