[Hardware TIPs] Hot Plug and Hot Swap Functions for SATA HDDs

most of the motherboard in the market now supports Hot Plug function for SATA Devices. Usually, each
power wire will provide 2 power connectors for HDDs. We suggest you to connect SATA HDDs to different power wires to prevent intervention. Basically, If the SATA HDDs are NOT set for RAID configuration, it is called “Hot Plug” for the action to insert and remove the SATA HDDs while the system is still power-on and in working condition.However, please note that it cannot perform Hot Plug if the OS has been installed into the SATA HDD.

As to Hot Swap support, if If SATA HDDs are built as RAID1 then it is called “Hot Swap” for the action to insert and remove the SATA HDDs while the system is still power-on and in working condition.
