Activity light for SATA

[antihero3zx]

So i was thinking it would be a fun nerd project to add LED's to the homemade NAS. I cant even decide on the direction to approach first.. the sata interface? the hard drive itself? some kind of inductive solution on the arm?

any ideas?

The LED pin on the controller chip. No other way.

At 1.5GHz, are you going to be interfering with the signalling?
