Issue with thunderbolt Hard drive

[Ben1l]

I have a mac pro 4, with a raid drive connected via usb. When I eject the drive it puts the raid unit to sleep. When I do the exact same thing when the drive is connected to my mbp (via thunderbolt) it does not put the drive to sleep.

Any ideas why, or ideas how to stop this happening?

From my thunderbolt storage experience, the RAID unit does not turn into sleep mode when I eject the RAID volume.

I have two thunderbolt storage devices, G-Raid with thunderbolt and Akitio's 2.5" thunderbolt enclosure. Akitio enclosure turns off whenever I turn my computer off / sleep and G-Raid needed to be turned off manually.

May I know which thunderbolt storage you have?

Sure, It's the Areca 4 bay.

Frustrating that it won't go to sleep on eject over thunderbolt like it does over USB, as it's noisy and it would be nice to quiet it down when I'm not using it.

I found this at Areca's official website: "Intelligent Power On/Off Function: Turn ARC-5026 power in unison with the host computer power status for data integrity."

obviously this unit won't be turned off while your computer is powered on.
