Testing the drive

We recently upgraded our hardware test bed to allow for a more stable and powerful workhorse.
Albatron 865PE Pro II
Intel Pentium 4 2.4GHz 800FSB
4 x 512 DDR OCZ PC3200 EL
Maxtor 80GB 7200RPM 8MB Cache
Windows XP SP1
Using DVD/CD Speed 2.01, we had run a battery of read, write and rewrite tests on the drive.

Our drives CD and read speeds were very similar to the Plextor 8X 708A. We noticed that CD seek times were a little higher than average, but on the other hand, DVD speeds were significantly lower. The 110ms seek time for DVD+R/W's is almost 1/3 of the Plextor 708A seeks. Our tests find the Nu Tech DDW-081 about 15% - 20% faster seeking than the Pioneer A06.


Label Rating Average Transfer Seek Random Seek 1/3 Seek Full Media Length
Ritek 97m31s01f (Cyanine AZO) 52X CDR 31.48X 101ms 110ms 160ms 69.59.51 CAV
Mitsubishi 97m23s24f 24X CDRW 20.41X 103ms 113ms 170ms 74.41.01 CAV
YUDEN000T01 4X DVD+R 6.17X 103ms 120ms 172ms 4.38GB CLV
MCC 002 8X DVD+R 6.22X 96ms 116ms 170ms 4.38GB CAV
Ricoh RICOHJPN 2.4X DVD+RW 6.22X 109ms 120ms 182ms 4.38GB CLV

Unfortunately, near the end of a long burn or read, the drive began to rattle slightly. Although it does not seem critical, at least not yet, there is some concern that this rattle could damage the media or the drive. The eject time of the unit is a little slow — around 12.13 seconds.

    There are two things I'd like to point out. The first being DiskInfoPro identified the MCC disk as 8X before it was burned. Furthermore, the FujiFilm disk was identified as 4X on the box, and 4X in DiskInfoPro before it was burned.

    #12: Thank you for the updated link. The PDF I recieved was straight from QSI and I was unaware there was an update on the chipset.

    Cheers,

    Yes... MMC 02 is capable of 8x with that drive. That's why your utility is saying that. However, that doesn't mean that Verbatim/Mitsu. actually rates it at that speed.
  • Anonymous User - Thursday, October 23, 2003 - link

    One more thing, in the review you claim that the PNX7850 chipset does not support 8x speed. Not true, it does: http://www.semiconductors.philips.com/acrobat/lite...
    It was only early versions that didn't support 8x. The PDF you link to is for the complete reference design where the Philips OPU 66.20 limits the speed to 4x (I assume QSI uses a different PUH).

    Then Diskinfo is wrong because MCC 002 (as in Mitsubishi Chemical Corp. and not MMC) DVD+R media are only certified for 4x speed. Use DVDInfoPro or DVDIndentifier instead for checking the media.

    Thanks Christopher :)for the links

    #1: We did not have a verbatim disk included. We have a 4X DVD+RW instead. Remember, we had a review sample so ours might have been slightly different. We had to upgrade from QSI firmware just to bring ours to spec with the retail drives.

    #2: DiskInfo, kind of a neat utlity, claimed the MMC 02 disk is capable of 4X and 8X.

    I uploaded the firmware for anyone who wants to download it. Its on the last page of the article.

    Cheers,
