Aside from price, the things people look look at most most when buying recordable media is longevity, compatibility, writing quality, and consistency. For example, if you're buying media rated at 16x, you want to be able to write at that speed with the drives you own. Also, you want your data to be readable now as well as long into the future.
Longevity of recordable media is something that's hard to evaluate. Without storing media for months, or even years, under different conditions, its hard to determine whether or not its a good medium for archiving data. In the past, the Library of Congress and the National Institute of Standards and Technology did comprehensive studies that looked at optical disc longevity, but I haven't seen a good one in at least a decade.
With this in mind, we're going to focus mostly on the compatibility, writing quality and consistency with the Moser Baer Zebra DVD-R media:
Compatibility - Will the drive write to it at its rated speed (or better)?
Writing quality - Do the PI (Parity Inner), PIF (Parity Inner Fail) and Jitter rates stay within an acceptable range?
Consistency - Is the performance and writing quality consistent from one drive to another? Is it consistent from one batch to another? This also applies to the manufacturing of the discs itself as well as the printable surface.
The next issue to tackle here was to decide which drives to use. Instead of using a bunch of old drives, I decided to go with those that are currently available at retail. This meant that, aside from the LG BH16NS40, I ended up buying a number of new drives. All of them were manufactured within the last year or two and were equipped with the latest firmware available from the manufacturer.
Drives and firmware used:Lite-On iHAS124 F (CL9N)
Plextor PX-891SAF (1.JN)
LG GH24NSC0 (LY00)
Optiarc AD-5290S+ (1.RN)
LG BH16NS40 (1.03)
To do the write quality testing, I used the Lite-On iHAS124 and Opti Drive Control.
So what are "good" results supposed to look like? When testing with the iHAS124 and ODC, the PI errors should not exceed 280 and the number of PIF errors should stay below 4. Since POF errors are uncorrectable, we really don't want to see any of them at all.
As a baseline, I tested some DVD-R media from a few other manufacturers as well as Moser Baer's Pro Select DVD-R media.
