I just got the bare drive and discs. The drive installs as any SATA-based drive does: easily. I put mine in an external enclosure.

First thing I notice is that the discs themselves are heavier (literally) than other DVD-R’s, and they are about 70% transparent.

Mac sees the drive; Toast writes to it; writes are pretty slow: 13 minutes for a full disc + about the same or slightly less to verify.

The discs are made somewhere in the EU.
They are more transparent after burning (a light smokey gray) that is transparent enough to read a book thru;

Disc was readable by my LG Blu-Ray burner/drive and by my Optiarc burner/drive.

So: no problems; everything worked as advertised.

See you in 3011…   🙂
