Acer CRW2010A CD-RW

2. Data Tests

Acer CRW2010A IDE CDR-W - Page 2

Data Tests

Test Method:
- SCSI Mechanic v3.0x: This was used to compare the Acer's  I/O performance against other various CDR-W drives (see charts). We used a pressed CD containing PlexTools v1.08 for all of the tests.
- Nero CD Speed v0.83b was also used to check the drive's performance with pressed CDs. For that test, we used PlexTools v1.08 pressed CD.

- SCSI Mechanic v3.0x results:

The Acer 2010 is the slowest among the 4 tested drives. The drive showed a un-pleasant behaviour with the PlexTools 1.08 pressed CD, especially while it was connected as MASTER. After a suggestion made by the Acer tech support, we connected the drive as SLAVE and most of our problems were solved.

The drive has a very good "Average Random I/O" due to low seek times, and earns the third place in the "Average Sequential I/O" test. The drive delivered around 4383kb/s, while the leader of the test, the MP7200, flies with 4555kb/s. Lastly, the performance in the "Average Same Sector I/O" test is not the best we have seen in our labs, since the drive managed to produce only 1445kb/s. The competition is much faster and the Yamaha 2200E can go up to 25400kb/s!

- Nero CD Speed v0.83 results: (click here to see the CD Speed 99 graph)

Using Nero CD Speed 0.83, we confirmed that the Acer 2010 model gets the third place among our 4 contestants. The drive makes a rather slow entry with 14.34X speed, but the average reading speed is good (29.65X). The competition from Ricoh is strong since both MP7200/9200 are much faster.

In the "Seek Times" test results, the Acer 2010 gets the third place both Ricoh drives. The drive's random seek time is 95ms. The Ricoh MP9200 is still the leader with 88ms and the MP7200 comes second with 93ms.

- CDR Media: (click here to see the CD Speed 99 graph)

The Acer 2010 performed very good with CDR media and reached 40x (max) reading speed. The drive's average reading speed with CDR media was 30.28X and gets the second place under MP7200.
