RAID 0 array showing up as removable hardware

[miston]

Both of my raptors, which are in a RAID 0 array on my Nvidia controller, show up on the bottom right in the "Safely Remove Hardware" thing along with my external drive

why? Should I remove them? My other array (2 400 gig WDs) don't show up, though they are on the Silicon controller

It has to do with the fact that they are SATA. SATA has a feature where you can use it as hot swoppable hardware for RAID arrays. Dont remove it, just ignore it.
