Pioneer was once at the forefront of DVD technology. The DVR-110D, though, appears at the tail end of a period in which most burner manufacturers have upgraded the speeds of their products. The drive supports all formats - including the ability to read DVD-RAM discs - and the DVR-110D keeps pace with its competitors in the dual-layer stakes with 8x DVD+R DL burning.
We tested the Pioneer drive by transferring a 7.5GB file onto 2.4 speed DVD+R DL media, at 8x. This was completed in a fast time of 17 minutes 39 seconds, with a transfer rate of 7MBps. Its performance is on par with the ASUS DRW 1608P25 currently at number one in the Best Buys charts. The disc was read back in the DVR-110D, but it wasn't recognised in an older DVR-107D drive. Nero burn-quality checking on the disk showed a very erratic, inconsistent burn with errors on the disc.
In further testing, subsequent discs produced were read in the DVR-110D and most other drives in the Test Centre, but not in the older DVR-107D drive. This was due to the book type not defaulting to DVD-ROM.
In our tests, we transferred a 4GB file onto 16x DVD+R burnt in 7min 42sec, a transfer rate of 10MBps. This burn looked a lot cleaner, but it still produced erratic transfer speeds all along the disc when checked using Nero. Again, subsequent discs were burnt much more consistently. The DVR-110D delivered slow transfer speeds of 8.26MBps to the hard drive, with a burst rate of 25MBps - this is about half the speed of its competition.
Verdict: Pioneer is no longer leading the pack. Our varied test results have caused us to query the reliability of this drive's performance in the long-term. Damien Donnelly
