CD-ROM Performance Results

Low-Level Measurements

CD Winbench 99 measures random access times and sustained transfer rates.

The Artec starts off at 3067 KB/sec at the inner edge of our test CD, maxing out at 6290 KB/sec by the outer edge. These measures are slightly better than Artec's specs. Only Pioneer's over-achieving trio does better.

Access times come in at 80 ms - considerably swifter than the <100 ms spec and trailing only Toshiba's SD-M1401. Do speedy access times help in CD Winmark and copy tests?

CD-ROM Winmark 99

CD Winbench 99's CD-ROM Winmark runs through a timed script of accesses ripped from a variety of popular software programs. The score here represents an average from four different test discs obtained from Ziff-Davis. This allows testing each drive's ability to read from a range of discs pressed with identical data.

The Artec records an amazing 1710 KB/sec average with very little variation between the four test discs. This leads to a 6% advantage over the next-fastest DVD drive: Pioneer's DVD-305S. In fact, this is the 2nd fastest Winmark score that SR's ever measured. Only Toshiba's 48X CD-ROM can top it.

File and Disc Copy

This file copy test emphasizes sequential transfer rates by copying a single, 634 MB file. The three Pioneers lead the field because of their 44X max (measured) transfer rates. The Artec keeps up with the 40X Toshiba. Both trail the Pioneers by 12%.

The disc copy test introduces random accesses due to the multiple files and folders on the test CD. Again, the Artec keeps pace with the Toshiba, while the Pioneers maintain an 8% lead here.

Digital Audio Extraction

SR measures DAE through two programs: CDSpeed99 and CDDAE99. CDSpeed99 represents a low-level measurement of DAE capabilities, while CDDAE99 is an actual audio ripping program that converts audio tracks on CD-DAs to .wav files on a hard drive.

In CDSpeed99, the Artec displays DAE potential of 9X-20X CAV. Across the entire CD-DA, this averages out to 15.4X - quite impressive for a DVD drive. Only the DVD-116 with its 16X CLV performance is better. Keep in mind that with the DVD-116, on-the-fly burning can be done at 12X and possibly even 16X, while the Artec limits burning to 8X speeds when feeding a burner due to its lower minimum extraction rate. CDSpeed99 reports perfect extraction quality as well as support for accurate streaming.

With CDDAE99, we move from the potential to the actual. The Artec extracts our entire 65-minute audio disc in 4:26. That comes out to a 14.7X average - a bit under the 15.4X average reported by CDSpeed99, but still impressive for a DVD drive. As with CDSpeed99, CDDAE99 reports perfect extraction quality with our slightly scratched test CD.

CD-R Media Compatibility and Performance

[an error occurred while processing the directive]

To test each drive's ability to read from a variety of CD-R and -RW media, we duplicate our pressed test CD to these discs and measure low-level performance with them.

With CD-Rs, the Artec maintains its pressed CD performance. There are no issues reading from TDK, Imation or Verbatim media. The drive reaches 43X at the outer edge of a 700 MB CD-R. Access times improve slightly to 76 ms.

CD-RW Media Compatibility and Performance

[an error occurred while processing the directive]

With nearly all optical drives, poor CD-RW media reflectivity slows read speeds down. Artec's drive is no exception: -RW read performance degrades to 10X-20X CAV. This is in the same range as the Toshiba, but well behind the Pioneers. At least the Artec maintains excellent access times with an 82 ms average. We had no problems reading from low and high-speed media from Sony, Verbatim, Memorex and TDK.
