Burn Tests CDR Media
We used the following configuration to test our burners:Albatron 865PE Pro II
Intel Pentium 4 2.4GHz 800FSB
2 x 512 DDR OCZ PC3200 EL
Maxtor 80GB 7200RPM 8MB PATA
Windows XP SP1
Below are the corresponding firmwares to each drive that we used:
| Drive | Firmware |
| ASUS DRW-0802P | 1.13 |
| AOpen DDW8800 | 1.4A |
| Gigabyte GO-W0808A | USY1 |
| Nu Tech DDW-082 | B372 |
| Sony DRU-530A | 2.0A |
| Sony DRU-700A | VYV3 |
| Toshiba SD-R5272 | 1030 |
Higher burn speed averages are more desirable.

| Drive | Average Burn | Length | Mode |
| AOpen DDW8800 | 27.13X | 79:57.71 | Z-CLV |
| ASUS DRW-0802P | 22.39X | 79:57.71 | Z-CLV |
| Gigabyte GO-W0808A | 31.65X | 79:57.71 | CAV |
| Nu Tech DDW-082 | 23.51X | 79:57.71 | P-CAV |
| Sony DRU-530A | 29.39X | 79:57.71 | P-CAV |
| Sony DRU-700A | 31.62X | 79:57.71 | CAV |
| Toshiba SD-R5272 | 22.89X | 79:57.71 | Z-CLV |
| Mitsubishi 97m23s24f - 24X CDRW | |||
| Drive | Average Burn | Length | Mode |
| AOpen DDW8800 | 16.00X | 74:43.00 | CLV |
| ASUS DRW-0802P | 22.26X | 74:43.00 | Z-CLV |
| Gigabyte GO-W0808A | - | 74:43.00 | - |
| Nu Tech DDW-082 | 21.22X | 74:43.00 | Z-CLV |
| Sony DRU-530A | 22.40X | 74:43.00 | P-CAV |
| Sony DRU-700A | 22.35X | 74:43.00 | Z-CLV |
| Toshiba SD-R5272 | 15.78X | 74:43.00 | Z-CLV |
Almost to no surprise, the DRU-700A had the same very high CDR burn speeds found on the Gigabyte GO-W0808A.

I have the Sony DRU700A drive deals posted in the Anandtech "hot deal" forum here: http://forums.anandtech.com/messageview.cfm?catid=...FYI: Here's a quote from Philips, who created the DL format. Quote: (According to Philips it will not be possible to upgrade existing 8x DVD recorders to DL layer recorders, contrary to what some rumours are saying. In theory the laser power of an 8x drive is strong enough to handle DL but the problem is, is that the OPU (Optical Pickup Unit) of the drive is often not good enough. This will lead to quality problems. However, some drives with good OPUs could, in theory, be upgraded although they’d have to be handpicked)

mmm looks up his dvd burner model :DKristopherKubicki - Wednesday, May 5, 2004 - link
hahher:fairly likely. As we mentioned in the review we firmware upgraded our GO-W0808A to DL.

According to Sony, its $199.99 right now.hahher - Wednesday, May 5, 2004 - link
what about price of this burner? price of other burnes (lite-on)?since components are similar to other current burners, how likely is it to see firmware upgrades to DL?

Hmm.. maybe you should ask the author Karr.KristopherKubicki - Wednesday, May 5, 2004 - link
Ian@CDRlabs: Not officially.Kristopher

KProbe2 does support PI/PO error testing (or BLER as you call them) for DVD+R DL.LoneWolf15 - Wednesday, May 5, 2004 - link
First of all, finding Dual Layer DVD media will likely take some time. Even though it isn't hard to find DVD+R/DVD-R media now, finding quality media for a reasonable price is still a gamble, much like CD-R media was in its earlier days.Secondly, if this drive has different pickups then it isn't "essentially the same as the Gigabyte" DVD writer. To write to the second layer of a dual layer DVD, more sensitive mechanisms are needed, and obviously this was done. Just because two DVD writers have the same chipset does not mean they will burn the same; if they have a different pickup mechanism, the drives will likely differ in performance. This has already been proven by the NEC 2500A and Pioneer 107D, which both use the same chipset but do not have exactly the same performance.
