There you have it, 8X DVD+R — exactly 8 minutes to burn 4.38GB. CD Speed incorrectly identifies the 8X Z-CLV (zone constant linear velocity) mode as 6X CLV due to PoweRec. As you may have read on the previous page, PoweRec redefines the laser intensity and spin at its own discretion.
However, we do have a complaint or two about the tiny buffer on the drive. During the above burn, we did not touch the PC at all. Below is a graph of 4X DVD+R media while we had a Microsoft Office document open. The spikes are the points where we saved the sub-100kb document. We are happy that the burn did not under-run; but, has optical storage taken a step backward?

Below are the CD-R, CD+RW, DVD+R, DVD+RW, DVD-R and DVD-RW speed tests. We used CD Speed with the same configuration as the previous test.
| Average Transfer | Media Length | |
| Imation 52X CDR Data CD | 29.31X | 79.49.74 |
| PNY 52X CDR Data CD | 29.24X | 79.49.74 |
| Mitsubishi 32X CDRW Data CD | 23.78X | 73:43.00 |
| Mitsubishi 24X CDRW Data CD | 23.66X | 73:43.00 |
| FujiFilm 4X DVD-R Data CD | 4.01X | 4.38GB |
| TDK 4X DVD-R Data CD | 4.00X | 4.38GB |
| FujiFilm 4X DVD+R Data CD | 7.70X | 4.38GB |
| Imation 4X DVD+R Data CD | 7.69X | 4.38GB | FujiFilm 4X DVD-RW Data CD | 4.05X | 4.38GB | FujiFilm 2.4X DVD+RW Data CD | 2.41X | 4.38GB |
The drive had no problem at all burning other 4X DVD+R media at 8X. Perhaps because the 8X DVD-R format is not officially standard, the 708A does not have the proper strategy logic to burn 8X DVD-R. As future BIOS upgrade to enable 8X DVD-R certainly seems feasible, it is obvious that no one will know until the DVD dash R forum gets their ducks in a row.
Full erase of a DVD+RW takes 24:23 minutes. A similar time was recorded for DVD-RW.

In the sentence:" As far as performance is concerned, the drive out-performs the ASUS DRW-0402P/D and the Pioneer A06 in virtually every way. Media recognition, compatibility and just raw burn times were all better on the A06."
I got the impression the author meant, instead of that last AO6 to put 7o8A.

#6 - Correct I didnt mention Sony, but thats because Sony doesnt make their own drives =). I have an upcoming review to deal with that.Kristopher

Couple things... I have a Sony 510A, 510UL and the Plex 708A. Buffer size is pointless. Those comments regarding the buffer size that folks are making and are mentioned in the review don't mean squat. Buffer underrun prevents coasters from happening and based on the review it's obvious it's doing its job. A 8MB buffer is just a way to differentiate a drive from its competitors for ignorant consumers that have "bigger is better" Best Buy logic.-R has greater compatbility at this point with all DVD players. +R has compatibility issues with some older players. That's the nice thing about having a dual format drive. One format doesn't work, try the other.
Lastly the reviewer forgot to comment on Sony as being one of the DVD burning elite. They set the standatd for the industry when they released the Sony 500A/X which was the first dual format burner on the market for months. Also, with firmware 2.0F that enabled 4X burning for both formats (nice free bump for consumers), they started the speed wars in the DVD burning market.

Anyone who buys a dual format drive is foolish. DVD+R only drives allow booktype settings to be set to dvd-rom, increasing compatibility SIGNIFICANTLY. Once the drive becomes dual format however, the feature gets scrapped.Mday - Saturday, September 13, 2003 - link
2.4x DVD burning is over 3MB ps. obviously 6x or 8x is 2-3 times that, or roughly 6MB to 9MB per second. with a 2 MB buffer, that's less than 1/3 of a second time. in computing terms, 1/3 of a second is a lot of time. however, since when do programs that access disc space only last 1/3 of a second...sony has an 8MB buffer. while burning at 4x, and with certain programs running, it hardly dips below 90%. of course i do implement a hefty disk cache and memory cache for nero as i burn. i would like to see nero have more than just 80 MB max dedicated for buffering in system memory.

I'm waiting for 8X DVD-R burners to come out. DVD+R discs do not work on any of the IBM T20-22 Laptops we use at my office. All of them play DVD-R fine so I consider that a negative towards +R. My friends DVD player from Sony works great with -R but not +R as well.Budman - Saturday, September 13, 2003 - link
