I have the tower set for 24X. I also put a drive in a PC and burned with Nero CD/DVD speed and got the same results. I tried older batches of TY media and it is about the same - maybe a little less with the old media but that was only one or two scans so I wouldn’t make an assumption.
For sure it is TY as I import it myself right from the source.
I tried some cheap media and got predictable results as below.
Ridata actually came out pretty normal without all these huge spikes but again that was only one test.
If anyone can please test their 115 with CD-R and let me know how it is. I suspect I have run into a bad batch of drives. How much QC are they doing on a $30 drive…
