Not sure what NAS to buy

[Enquiries]

Hi, I really enjoy your videos, they're very helpful but I'm not very techie and could use some help please. I want to purchase a Synology NAS to save all of my family pictures and home videos, I also have a drone so will have some 4k footage as well. But I'm still not sure what NAS would work for me.
I was thinking about a 1522 or an 1821, I want to be sure I have enough drives for future needs, I plan on starting out with four 14TB Iron Wolf drives and using RAID 6. Here's my concern, neither of these NAS are good for transcoding, but do I need Transcoding for home videos & drone videos? I reached out to Synology's chat for help, but they referenced me to their FAQ's that didn't have the models I'm considering. 
I'm very confused and don't want to mess up, any recommendations would be appreciated, thank you!

The Synology DS1522+ and DS1821+ are both good choices for a NAS that can store and manage your family pictures, home videos, and drone footage. Both of these NAS devices have a number of features that make them well-suited for home use, including support for large storage capacity, data protection, and file sharing.

In terms of transcoding, this refers to the process of converting video files from one format to another so that they can be played on different devices. In general, you don't need transcoding for home videos and drone footage, as these types of files are typically already in a format that can be played on most devices. However, if you want to be able to stream your videos to a device that doesn't natively support the file format (e.g., an older TV), then transcoding may be useful.

Both the DS1522+ and DS1821+ have powerful processors and plenty of storage capacity, which should be sufficient for storing and managing your family pictures, home videos, and drone footage. The main difference between the two is the number of drive bays: the DS1522+ has five bays, while the DS1821+ has eight bays. This means that the DS1821+ would be a better choice if you plan on adding more drives in the future or if you need more storage capacity upfront.

Overall, either the DS1522+ or DS1821+ would be a good choice for your needs. You might want to read reviews and compare the features of each one to determine which one is the best fit for you.
