5 Things to Know About Expanding the DS420+ to 9 Bays
- The DS420+ supports one DX517 expansion unit via eSATA, adding 5 drive bays for a total of 9.
- You must use the same drive type (HDD or SSD) across all bays for best performance.
- Expansion does not increase processing power or RAM; the DS420+ remains the bottleneck for heavy workloads.
- Volume management is simpler if you create a single storage pool across all bays, but you can also keep them separate.
- The DX517 is not hot-swappable for the DS420+; power down before connecting or disconnecting.
