Conclusion

Pros	Cons
48/24/48 CD-RW Good seek time with CDs Good behavior with CD-Check Audio Test Disc Rip full contents of 90/99min disc Creates working backups from protected CDs Supports CD-Text (reading/writing) Fast DVD ripping Fast ripping speed with protected game discs Overburning up to 99min Supports Mount Rainier Low price	Cannot playback/rip CDS200 protected AudioCD Increased jitter at speeds over 24x Behaviour with ABEX TDR-841 test disc Low score with ABEX TCD-721R test disc

TEAC's DW-548D drive, is another one combo drive out to market antagonism. It claims a nice stand out there, having reading speed at 48x for CD-ROMs, 24x for CD-RWs and 16x for DVD-ROMs. Also supports most read featsures, having buffer underrun protection, plus Mount Rainier.

Testing the drive we show common results for reading media, but very good results when drive seek data. When it meets badly scratched discs the drive start to read slow, trying to get accurate data, finished with succes and having high average score at 74,2%.

The behavior with our Audio CD's during the error correction tests was quite good, reading up to the 4th level but no the 5th (1,500mm scratch). All of our test for DVD's, played successfully on the drive without any errors to be reported, except dual layer PTP media were the second layer can`t be readed, making the drive reading long time the same area without succes. This drive gave us an outstanding high transfer rate result, ripping test DVD media.

With protected disc backups, the drive make it good. The drive was in most instances fast with ripping the game titles we tried, giving good manage and nice performance.

Teac`s drive gave us average ripping speed at 32,1x for audio extraction and quality at 100. Also drive rip full contents of 90/99min disc. Unfortunately the drive didn't manage to play/rip the CDS200 protected Audio CD, thing that didn't happen with Key2AudioCD.

From writing tests, we generally saw good performance, with good recording times and the tests confirmed the manufacturers specifications. Teac succesfully complete overburning writing up to 99min media.

As far as CD writing quality is concerned, from the measurements that we did with various manufacturers media, it can be generally said that it had a good average. Unfortunately, we only have good writing results (low jitter value), when writing speeds are around the middle of the speeds, which drive offers. The C1 levels were good, while there were no C2 errors reported, if we put out Mam`s and Ritek`s media.

The drive's price on the market is around $67,44~89. Maybe with a bit of searching you may be able to find lower prices.

Summarizing i can say that Teac`s drive is a nice device for home use and covers with succes more than 70% of the works that it has to do.
