How to set up these devices?

You can setup both devices in the same way by going through the below-mentioned steps:

  1. First of all, you have to install the drives into the drive bays.
  2. For this purpose unlock the drive tray and place your drive on it.
  3. Inject the loaded drive tray into the vacant drive bay.
  4. Repeat the same process to install other drives into the drive bays.
  5. After that use a LAN cable to connect your device with the router.
  6. One end of the AC power adapter is to be connected with the power port.
  7. One end of the AC power cable is to be connected with the AC adapter and the other end to the power outlet.
  8. Hit the power button to activate your DiskStation.

These models of Synology have granted their users one of the easiest installations as there is no need of removing the cover or case to install the drives.

Operating temparatures:

Both devices have the same operating and storage temperatures.

They have the same operating humidity but DS1520+ is noisier as compared to its counterpart.

This is because Synology DS1520+ can reside more drives that vibrate more violently and produces more noise.

Operating Temperature32 – 104°F32 – 104°F
Noise Level (dBA)19.8 dBA20.8 dBA
