| TEAC CD-W552PUK USB 2.0 - Test Results |
|
This is my test setup Well now we have all the fancy technical glossary out of the way, we can get down to the nitty gritty and run some tests on the drive to see just if all this technical mumbo jumbo actually makes any difference to your CD burning. Im also going to compare my tests with an internal IDE Liteon 48x speed burner --- not to directly compare a 48 speed burner with a 52 speed burner of course, but just to see if there are any noticeable speed improvements. In the past I have tested speeds between a Liteon 48 and a 52 speed burner and found no difference at all, but I felt it a worthy little side test in the case of this article.
This image shows the drives maximum burning speed of 52x via the USB2 interface along with the 2MB recorder buffer and burn proof enabled by default. Of course its worth pointing out to many people new to CD burning that only at a certain part of the CD burning phase are maximum speeds achieved. For those of you interested in learning more about CD and the technology behind it, have a look at this site for further information. Nero Burning: 700 meg CD For the purposes of this test I have gathered together a full 702MB of MP3 files to test the drive with on burning speeds. I will compare the TEAC drive with my internal Liteon 48 speed IDE drive, which I have found to be an exceptionally fast drive. My first test was to burn a full 702meg
of data of Mp3 file backups onto Memorex 52x branded media.
Setting up the options in nero for the ISO burn.
. The complete ISO image
data as you can see from the above image took a total of 2.42 seconds,
a nice result, but nothing really that outstanding for 52 speed. As
you can also see the IDE liteon drive finished the same data burn in
2.40 - 2 seconds faster, not really very noticeable in everyday use.
TEAC Drive noise is low, much lower than the Liteon drive and the overall
feel of the mechanism/opening tray is very good, certainly matching
the outward visual quality that I detailed on the first page of this
article.
Nero CD speed: I ran this test on each drive 5 times with various discs to get a rough idea, then I used a master test disc I have in my posession which I know has been burned to a very high level to ensure the figures gained from this test are accurate.
This is an interesting set of results, and gives a better indication of the improved speeds of the TEAC drive over the Liteon with a higher lowest speed starting at 23.77 compared with 21.95m, an average rate of 38.65 compared with 35.71 and a total data transfer speed of 50.93 compared to 47.37. This of course while sounding impressive will not be that noticeable in everyday use. But still a fine set of results for a drive which can be easily moved between machines and locations. If we take a look at the seek times we see the internal Liteon drive is marginally better, certainly not noticeable in real world usage, im attributing some of this perhaps to the USBs interface medium. On a good note, both drives have very low CPU overhead usage figures, with it being 1% lower on the TEAC drive all along the charting. The burst rate figures are also more than likely down to the interface medium as well as the seek times I noted earlier but its quite a major drop in burst performance, dropping from 21mbs on the internal IDE interface to a mere 11mb on the external USB2 interface. Ill be attempting to find out more about this. Next im going to concentrate on Audio Extraction ....
