SSD Activity Light on the System Is Always On





Learn more about the HDD/SSD Activity light on the motherboard/system and how it reacts with the Intel® Optane™ SSD 905P Series in the system.

What is the concern?

When the device is in the system, the HDD/SSD Activity Light on the system is always on.


What was expected?

It was expected that the light would always be OFF, then flicker ON when the storage device is being accessed. (For example, when opening a document or saving something.)


Why is this happening?

This is expected for a system with the Intel® Optane™ SSD 905P series attached.

Note If there's more than one storage device in the system, the light being on or off with activity could vary. It depends on the implementation of the motherboard/system. Please consult the motherboard/system vendor and user manual for more information.

The reason is that this device is set to have the light ON if there's no activity on the device and goes OFF when the device is being accessed.

This is the opposite of many storage devices. (So it shows OFF if there's no activity on the device and goes ON when the device is being accessed.)
