Store all your files on a Synology internal HDD. You can use these internal hard drives the entire day in a Synology NAS> Thanks to the shock absorbers and good ventilation, these hard drives work without slowing down. Because you can create a large Synology environment with these hard drives, you receive updates faster. That way, your NAS and hard drive always work with the latest software and hardware versions. Have a NAS from a different brand, such as QNAP? Check if your NAS is included on the list from Synology.
