I've just received the Plextor Premium drive and I did a couple of tests. First impression of this drive is simply: wow. It looks good, it's very silent (even the drive's tray) and check out my results with SafeDisc/SecuRom:
Mafia, SafeDisc v2.70.030: works, without AWS! Tested in:
Neverwinter Nights, SecuRom 4.76.00 0051, back-up works (nothing new here) but the disc was read in 2m:55s, 22.6X average read speed. Although the SubChannels could not be read at top speed, the Premium drive is not limited to 8x like we saw on some older Plextor drives..
A complete review is on its way of course, please be patient
