|   | Low Speed: This disc was burned at 16x since my burner doesn't support 20x burning (for some unknown reason). As you may have noticed from the top section of the graph, I ran this test at 8x, which was the speed I tested at when I used CD-Doctor. I will now also be including tests done at 40x for comparison (see below). High Speed: As you can see, the C1 error maximum amount per sector is still listed as being only 12, however the C1 average errors per sector is now listed as being approximately 400 errors higher then when tested at 8x. These sorts of deviations are common and nothing to be worried about. The simple explanation is, when the CD is being tested slowly (ie. 8x) there is more time "digesting" the data, but when you test at higher speeds, it is more difficult for the drive to correct any errors and you usually get an increase from the slower tests. So the high speed tests will tell you how the CD-R will perform under normal situations (ie. playing games off of it, copying data from it etc...) and the low speed testing will tell you your chances of recovering data from it under ideal conditions. with that said, let's take a look at CDs number 2 and 3!   |

|   | Low Speed: Again this test was done at 8x, and you will notice that the results are very similar to CD #1's, only perhaps a little better! High Speed: As with CD #1 the deviation between high and low speed testing on CD #2 is VERY little, and in my opinion inconsequential.   |

|   | Low Speed: We see a slight increase in C1 errors now with CD #3, however the quality of this CD-R is still within the *VERY GOOD* range. Let's take a look at how the scores differ when the CD is tested at higher speeds... High Speed: We now see the first significant deviation between high and low speed testing, and the reported error rate is now roughly 2.5 to 3 times greater then it was reported when the CD-R was tested at 8x! However, I should note that this CD-R is still performing incredibly well regardless. Now let's take a look at how these CD-Rs perform when pushed past their certified limits!   |
