CDR Tests

The Mitsumi CR-4809TE uses Z-CLV for achieving 24x-writing speed. Below is a graph that represents the main differences of Mitsumi's implementation of Z-CLV writing technology compared to the fastest 24x Z-CLV recorder from Plextor. The Mitsumi writing graph is almost the same with the faster 24x Z-CLV recorder from Plextor:

The Mitsumi drive starts writing at 16x (0 mins), shifts to 20x at 6mins, shifts again up to 24x at 186ins and writes at 24x till the end of the disc. The drive has the same shift points with Plextor's PX-W2410A, however due to lower speed in the shift points is slighter slower than the Plextor recorder. In the following table we can see the average writing speed of the TEAC CD-W524E, PleXWriter PX-W2410A, LiteOn LTR-24102B and Mitsumi CR-4809TE, according to the Nero CD Speed:

The Mitsumi CR-4809TE has an average writing speed of 22.72X, which is the third best among the four tested drives.

The Mitsumi CR-4809TE has the same rotation speeds as the PleXWriter PX-W2410A, at least in the shift points.

- Procedure

We tested the Mitsumi CR-4809TE with Nero v5.5.5.6, Ahead InCD v3.12b, CloneCD v3.1.1.0 and, Padus DJ v3.50.799 software. We used various of media for performing our tests: Mitsubishi Chemicals 74/80min 24x certified, Mitsui 74min 24x certified, Taiyo Yuden 74/80min 24x certified, Ricoh 74min 24x certified and Ricoh's 74min HS-RW. The Mitsumi drive includes a build-in mechanism, which automatically reduces the writing speeding during the burn process. The drive doesn't limit the recording speed inside the recording software or show any sign at the beginning of writing but the final recording time unveils it.

- 74min CD-R Tests

We created a "DataCD" job with data slightly more than 74mins (74:03:65). We burned the same job with all 4 CDR-W drives:

The Mitsumi CR-4809TE has the higher burning time at 16x (CLV) writing speed. It needs 320secs to end the task. The CPU usage seems be increased and reaches the 18%!

The Mitsumi CR-4809TE is not the fastest 24x Z-CLV recorder you can buy nowadays. The drive after writing many media at 24x, had as the best recording time 242secs. The disappointing issue is the higher recording time with almost 28%. The PleXWriter PX-W2410A is 11secs faster. Future updates can improve writing performance...

- 80min CD-R Tests

In our normal burning tests the 80min CD contains slightly more than 80min data (80:01:47):

Again the Mitsumi CR-4809TE is the slowest drive at the 16x writing speed.

The Mitsumi CR-4809TE with 80min CDs is the slowest drive and its best recording performance was 257secs. The TEAC CD-W524E is 10secs faster.

- Overburning Tests

Using Nero CD Speed, we saw that the drive can overburn up to 99:00minutes:

- CD-Text Results

We created several AudioCDs with CD-Text enabled. The Mitsumi CR-4809TE can read/write CD-Text AudioCDs without any problems.

- CloneCD Writing Tests

The CloneCD v3.1.1.0 reports that the drive supports the DAO-RAW feature. We performed our usual tests and we confirmed that the drive supports fully the DAO-RAW writing mode (Safedisc 1.0, LaserLock 1/2 and SecuROM 2).

- SD2 Support
For the SD2 test we used the "No One Lives For Ever", "Max Payne" and "Emperor Battle of Dune" game titles. We used the Mitsumi CR-4809TE both as reader/writer. The produced backup didn't work using the same or any drive we tested with. Therefore, the Mitsumi CR-4809TE cannot produce SD2 working backups.

- 8cm mini CDs

The Mitsumi CR-4809TE supports reading/writing of 8cm CDs.

- Buffer Underrun tests

The Mitsumi CR-4809TE supports "ExacLink" anti-buffer underrun technology, which was developed by OAK Technologies. The drive worked without any problems when buffer underrun caused from our side. When you press ctrl+alt+del the drive will start blinking and when you un-freeze the PC will continue writing :-)
