NVMe SSD Cache - Enquiries - 01-08-2023
Looking at add WD Red SN700 NAS NVMe SSD for SSD cache and was wondering if adding these will delete current data on HDD (raid 5) on DS1821+ ?
RE: NVMe SSD Cache - ed - 01-09-2023
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.
