Samsung SH-S223Q 22x DVD±RW/RAM

While CPU, memory, OS and other variables don't often make a huge difference, there are some nonetheless. We have a computer that is used only for testing hardware. We do this so all tests can be compared reliably.

Test System:

For DVD writers the performance tests are broken down into four sections: CD read, CD write, DVD read and DVD write tests. Each benchmark test has been run three times. The score given is an average of the three. DMA has been enabled in device manager for all IDE devices supporting it.

CD Read Tests: For the read performance section of the CD-ROM benchmarks, CD WinBench 99 and CD Speed are used to test transfer speeds, seek times and CPU usage. For DAE testing, CD Speed is used to give an overall speed rating and is used in combination with CD DAE to see how well a drive reads scratched and dirty discs.

CD Write Tests: To test the write speeds, Nero Burning Rom is used to write 700MB to our test media. Times are recorded. To test rewrite scores, Nero is used again to time how long it takes to write 400MB of random files and directories. Then Sonic's DLA is used to test packet writing speeds. The same files are copied and pasted in Windows Explorer and timed.

DVD Read Tests: For the read performance section of the DVD benchmarks, CD Speed is used to test read speeds, seek times, and CPU usage.

DVD Write Tests: To test the DVD write speeds, Nero Burning Rom is used to write 4GB to our test media. Times are recorded. Then Sonic's DLA is used to test packet writing speeds. The same files are copied and pasted in Windows Explorer and timed.

CD Winbench 99 Scores:

The CD Winbench test is as close as we can get to testing every day usage. It fires off eight different applications using scripts. This tries to mimic the activities of a person loading these programs onto their own computer.

Samsung's new DVD writer performed pretty well in our CD Winbench tests. In the transfer rate tests, the SH-S223Q started reading at 20.5x (3040 / 150) on the inside and reached a maximum speed of about 43x (6450 / 150) on the outside. The drive's access time and overall score were also quite good. However, its CPU utilization was a little higher than I would have liked.

CD Speed v4.7.7.16 - Pressed CD:

For this test I used a pressed CD containing one Mode 1 data track. The disc is 74:38 in size and is full of data and directories.

 

	Samsung SH-S223Q	LG GH22LP20	Optiarc AD-7200S	Samsung SH-S203N
Transfer Speed Average: Start: End:	35.98x 20.97x 47.60x	35.59x 20.56x 47.15x	35.50x 20.41x 46.96x	35.96x 20.75x 47.55x
Seek Times Random: 1/3: Full:	101ms 106ms 176ms	101ms 107ms 171ms	143ms 157ms 236ms	102ms 105ms 177ms

The SH-S223Q didn't perform as well as I had expected when reading pressed CD's. While rated at 48x, Samsung's new drive came up a little short of this number in our tests. On a more positive note, the SH-S223Q's seek times were very good. 

CD Speed v4.7.7.16 - CD-R Media:

For this test I made a copy of our pressed test CD. I used 12x rated Memorex Gold 74 minute media for the tests.

The SH-S223Q wasn't nearly as fast when reading CD-R media. Like the SH-S203N, it reached a maximum transfer speed of only 41x.

Samsung's new DVD writer had no problems recognizing our 99 minute CompUSA media. The SH-S223Q read our test disc from start to finish, reaching a maximum transfer speed of 44.67x.

CD Speed v4.7.7.16 - CD-RW Media:

For this test I made a copy of a pressed test CD. I used some PNY 80 minute CD-RW media for the tests.

Samsung's new drive also reads CD-RW media at 40x. As you can see, the SH-S223Q had no problem reaching this speed in our tests.

CD DAE and CD Speed v4.7.7.16 (DAE) - Pressed CD:

For this test I used Pure Funk. The CD is almost exactly 74 minutes. This helps to squeeze the maximum performance out of the CD.

Exact Audio Copy can tell us a lot about a drive's capabilities. You can see from the screen shot that while the Samsung SH-S223Q supports accurate stream and has the ability to retrieve C2 error information from the CD, it does not cache audio data.

 

CD Speed	Samsung SH-S223Q	LG GH22LP20	Optiarc AD-7200S	Samsung SH-S203N
Average: Start: End: DAE Quality: Accurate Stream:	30.66x 17.73x 40.44x 10 Yes	31.44x 18.21x 41.56x 10 Yes	30.89x 17.71x 40.00x 10 Yes	30.93x 17.76x 40.86x 10 Yes

The SH-S223Q did fairly well in our DAE tests. While not nearly as fast as some of the other DVD writers we've tested, it had no problems ripping pressed audio CD's at 40x.

CD DAE and CD Speed v4.7.7.16 (DAE) - CD-R Media:

For this test I used a copy of the Pure Funk CD. It's burned onto the same Memorex Gold 74 minute media I used in the CD Speed tests.

The SH-S223Q was slightly faster when ripping audio CD-R discs. Unfortunately, even with this increase in speed, it wasn't as fast as the LG GH22LP20. So how did it do in CD Speed's advanced DAE tests? Take a look below.

Samsung's new DVD writer completed CD Speed's advanced DAE tests with an average score of 29.14x. The drive had no problems passing all of the on-the-fly tests and did not create any errors.  If you look at the advanced features, you can see that the SH-S223Q was able to read the CD-Text and subchannel data but failed to read the lead in and lead out sections of the CD.

To see how well the SH-S223Q can read scratched and dirty discs, I used CD Speed's ScanDisc utility to see how many sectors were damaged or unreadable. This is a very rough, but good way to test the drive's error correcting abilities.

CD Speed - ScanDisc

The SH-S223Q handled scratched discs relatively well. By looking at the screenshot, you can see that the drive considered only 47.3% of the CD to be "damaged".  More importantly, none of the sectors on the disc were unreadable.

You can also get an idea of how well the drive can read scratched and dirty discs by using CD DAE. The application extracts the audio tracks twice and then compares them. From this information we can see what the drive's average speed was and how many errors it generated.

Here too, the SH-S223Q did pretty well. The scratches on the disc had little effect on the drive's speed and the number of errors remained relatively low.
