SSD cache is the leverage of faster solid-state storage to improve the performance of NAS-class mechanical drives. Hard drives are notoriously slower than SSDs, and by storing frequently accessed data on these drives, speeds can improve considerably. It’s easy to install SSD cache on a Synology NAS, so long as you have the necessary M.2 slots or free drive bays.
What is SSD cache on Synology NAS?
Not all Synology NAS enclosures support SSD cache, but if yours does and you have a spare drive bay or M.2 slot, you may be able to take advantage of improved system performance. Instead of accessing data from slower mechanical hard drives all the time, you can use faster SSDs (like aSamsung 970 EVO Plus) to store some of the most frequently accessed data.
To see whether your NAS supports this feature, please check to see if your enclosure is listed below.

Check how much cache your Synology NAS needs
Synology has an SSD Cache Analyzer tool that can help provide some insight into how much cache would be required to see notable performance improvements. To run this wizard, follow these steps:
The wizard will automatically begin totaling the size required, based on the size and number of recently accessed files on the selected volume.

Your Synology NAS will commence using the newly added SSD cache for improving the performance of the unit by storing frequently accessed data.
Samsung’s 970 EVO Plus is a rapid M.2 drive that’s capable of delivering stored data at vastly faster rates compared to NAS hard drives.
While an SSD still cannot compete against mechanical HDDs for value and capacity, Synology’s initial SSD offering with the SAT5200 is a step in the right direction. It’s a must-have for your NAS if you want flash storage.
