Adding a WD Red SN700 NAS NVMe SSD for cache should not delete any data that is currently stored on your HDD in a RAID 5 configuration on your DS1821+. Cache is a separate function from the main storage drives, and it is used to temporarily store frequently accessed data for faster access. When you add a cache drive, it should not affect the data that is already stored on your main storage drives.
However, it is always a good idea to make a backup of your data before making any changes to your storage setup, just in case something goes wrong. That way, you will have a copy of your data that you can use to restore your system if needed.
I hope this helps! Let me know if you have any other questions.
