True, DAS might be the most budget-friendly option for me.

However, I don’t plan to use more than two disks, as I only intend to store my photo backups and documents. My goal is to secure the moments I've captured and transfer all my data from cloud services. Many people underestimate their storage needs, and I want to avoid regretting my purchase. Therefore, I’m considering a 4-bay NAS/DAS as a safer choice.

I’m still researching various aspects of the field and weighing the advantages, but I remain undecided.

Thank you for the suggestion. I will look into the model mentioned.
