I’m thinking of picking up a SHM-165P6S (the dvd-ram capability is a key thing drawing me to this drive. I see though that there are several revisions available from retailers, up through like SHM-165P6S-09. I saw somewhere ( I think it was under the reviews at a retailer’s site) people recommending to stay away from the SHM-165P6S-03. I searched here to see if I could find any posts concerning whether any particular revisions of the drive were better or worse, but did find any. But just in case I figured I’d ask. So, is there any significant/worthwhile difference between the revisions of the SHM-165P6S?
