6 Things to Know About the Synology DS1623xs+ NAS

Regarding the Synology: 1. It has six SATA drive bays for 3.5-inch or 2.5-inch drives, giving you serious storage capacity in a compact chassis.

2. The two M.2 NVMe slots are for SSD caching only, not for adding storage to your pool.

3. Populating all six bays with drives makes the NVMe cache useful for speeding up frequent file access.

4. You cannot use the M.2 slots as a separate storage volume or for installing applications.

5. The cache helps with random read and write performance, but sequential transfers see less benefit.

6. If you need more storage bays, look at larger models instead of expecting the M.2 slots to expand capacity.
