DVD-RAM writing performance:
The Pioneer DVR-112 is a so-called Multi drive, meaning it also supports the DVD-RAM format.
This drive is one of few drives that also supports the DVD-RAM format, lets us look at the recording side of the disc, and as you can see it has differences from the other DVD+R/W/R9 DL and DVD-R/W discs.
We can see a very fascinating pattern of darker spots. These tick marks are "address information" ("Pre-mastered Pit Header Field") which are embedded onto the disc. This is header information in front of data sector area, and is the same format as HDD and MO.
A DVD-RAM’s disc can be formatted in the following formats:
- FAT32
- UDF 1.02
- UDF 1.50
- UDF 2.00
- UDF 2.01
- UDF 2.50
By formatting a DVD-RAM disc with FAT32 it will act like a removable hard drive and all writing will be done as “background processes”. Meaning you do not have to wait for it to finish, you can start or work with other applications while the DVD-RAM is working without noticing any “hangs” or CPU slowdowns.
DVD-RAM has error correction, but also has error replacement to spare sectors as a "defect management" function. This gives higher reliability than other DVD format.
Another advantage with DVD-RAM is that the discs can be formatted/erased/written at over 100.000 times before it will/can cause/report any errors. Let’s try to read back the 2 discs that we wrote:
Lets us take a look at the media we are going to use in these tests.
Maxell 12x rated DVD-RAM media
As we can see, the Pioneer DVR-112 wrote our 12x DVD-RAM media at its maximum rated speed of 12x in 5 minutes and 33 seconds.
Now let’s see if the Pioneer DVR-112 can read our test disc.
The Pioneer DVR-112 had no problems in reading our test disc at 12x.
Maxell 5x rated DVD-RAM media
As we can see, the Pioneer DVR-112 wrote our 5x DVD-RAM media at its maximum rated speed of 5x in 11 minutes and 6 seconds.
Now let’s see if the Pioneer DVR-112 can read our test disc.
The Pioneer DVR-112 had no problems in reading our test disc at 5x.
Summary:
The Pioneer DVR-112 proved reliable at both reading and writing our test DVD-RAM media. When using 12x media the drive completed a full disc in 5 minutes and 41 seconds, which should be fast enough for every day backups.
To round of this review, we will run some advanced tests on the Pioneer DVR-112 on the next page….
DVD+R DL/-R DL Writing performance
Protected audio CD's are not available in my location. Maybe you can send me some to test
Doesn't screenshot show contrary(C2 - no, cache - yes)? Or it is wrong screenshot?

Please update the review, because it's misleading.
The fact is they do support PI/PIF scanning just like the Pioneer drives do and that is all that is claimed in the review.
In addition huge spikes (up to PIE > 17 000) are often present on the graphs.
Your answer reminds me an old story with hotel reservation in India. If you just reserve a room with aircond there is a great chance that it will not working. In fact you must always precise "with working aircond" while booking.
I refolmulate me request. Could you please precise in the review that although the error reporting is indeed working, but the PIE level always exeeds the DVD+/-R specs. That is not the case with Lite-on, BENQ, NEC and Plextor.
This is not the case, BenQ and NEC drives often report out of spec scans on perfectly good burns. The Pioneer scan in the review is within specifcation.
I guarantee if you buy this, you will have lazer failiure in months, you have been warned.
A week later bought 2 Pioneer DVR-112D's from NewEgg, both of them are still working perfectly since March 2007, nothing but smooth sailing.
Also, overall the best DVD burner I've owned, next to the BenQ 1640...^_^
It totally ignores the lack of write quality as revealed in the well-known German computer magazine "c't" issue 2007/11 p. 122 which affects not only the Pioneer DVR-112 but a couple of new competitors drives as well.
Compared to an old test where they tested the DVR-111 (which I own) the write quality of the DVR-111 exceeded the write quality of the DVR-112 except for CD-R where the DVR-112 was better.
If these problems are not firmware based I would rather buy a DVR-111 again than a DVR-112.
c't assumes that the enourmous price pressure may have caused the degraded write quality with those new drives (not only Pioneer!) in their test.
I'm looking for some 110's or even 111's to replace them with.
Might try lite-on's instead next batch. Nightmare for me as a supplier. Cost me heaps ... just replacing discs alone.
No problem with any other type of disc. Awaiting advice from Pioneer.
Had 111D before this burner, excellent performer but couldn't write to dvd-ram.
By the way I'm going to buy another brand recorder for fail safe. Plextor - King of the quality? Well yes, but as well king of short life and failures! My opinion: never again!
I wonder what should I buy for second (backup-reserve) recorder? I was just thinking about Pioneer, while reading this review, when I read in the previous comments that they live short too. What a shame on Pioneer!
Gonna replace both of these with some newer DVR-115's
