- Comparison Charts:

Let's see how Acer's 20x Z-CLV compares against Ricoh's 20x Z-CLV and Yamaha's 20x P-CAV writing technologies:

Ricoh MP7200/MP9200 - support 20x Zone-CLV
Yamaha 2200E - support 20x P-CAV

As we described earlier, the Acer 2010 hits the 20x writing speed at 40-42mins making much slower than the rest 20x writing drives. The average writing speeds equals slight faster than a 16x CLV recorder!

The Acer 2010 keeps all the time it's rotations speed under 6000rpm. That equals to lower noise but also lower recording speeds. The rest drives and are faster:

As the following chart illustrates, the differences between Acer's, Ricoh's and Yamaha's 20x writing speed approaches are obvious for both 74 and 80min CDs. Compared to the Acer drive, the Ricoh drives are about 53secs faster and the Yamaha 2200E 30-35secs faster:

- Overburning Tests:
The Acer 2010 doesn't support overburning with Nero 5.5.2.4 software. Update to 5.5.3.0+

- CD-Text Results:
We made several AudioCDs with CD-Text and our tests showed that the drive can read/write CD-Text format.

- CloneCD Tests:
CloneCD v3.0.4.2 reported that the drive did support the DAO-RAW writing feature (only), and anti-coaster technology. From our tests results DAO-RAW writing works without any problems for SafeDisc 1 and LaserLock 1/2 protected CDs. You cannot backup SecuROM 2/PSX Libcrypt protections since the drive doesn't allow writing of SubChannel data.

- SD2 Support:
For the SD2 test we used the "No One Lives For Ever" CD title. We used the Acer 2010 both as reader/writer. The produced backup played flawlessly in the following drives:

The Acer 2010 drive denied to playback the SD2 backup it had itself created (a usual error in ~tmp file). We did try to playback another SD2 backup, created by an Iomega Predator USB, and it also didn't work.

On a last procedure we tried another SD2 backup, created by an Acer 1208, and the results were not what we expected. The SD2 backup created by Acer 1208 DID play without any problems on the Acer 2010. We assume our Acer 2010 model has some kind of defect, since this can easily be considered a malfunction, or else Acer engineers need to investigate on this phenomenon. The bottom line is that the Acer 2010 DOES make working SD2 backups!

- 8cm mini CDs:
The Acer 2010 worked without any problems in our simulation tests. We did try some business cards too, but we don't think that the Acer supports them.

- Buffer Underrun tests:
The Acer 2010 supports the "SeamLess Link" anti-coaster technology for making buffer Underrun error-free CDs. This technology doesn't need any setting and works with all the well known CDR software, including most older titles, since it is based upon the drive and not the software. The drive worked fine even under heavy CPU load pressure from our part (100% CPU Usage).
