4. RW reading tests

Sony CRX200E IDE DDCDR-W- Page 4

RW reading tests

- CD Speed 99 HS-RW tests: (click here for the CD Speed 99 graph)

For the RW tests we used the Verbatim HS RW media written at 8x speed. The Sony CRX200E performed quite good, giving around 16.05x as the average reading speed. The competition seems faster, except for the Acer CRX1208:

- CD Speed 99 DDCD-RW Tests:

According to CD-Speed 99 reports, the drive reads a DDCD-RW media with 8x speed. Seek times are much higher than with normal HS-RW media, and CPU usage for 8x reading seems very high (31%):


CloneCD Tests

- Procedure:
We used CloneCD (v3.0.0.14) and 3 original CDs (Rally Masters, V-Rally 2 Expert and Euro 2000) in order to test the reading time of Sony CRX200E. We also tested the reading performance with backups of the original CDs, since the reading speed varies between original and backup media. For comparison reasons we added the results of the already tested PleXWriter PX-W1210A, Acer 1208 and Ricoh MP7125A.The following picture shows the Sony CRX200E reading/writing capabilities:

- Results:

a) SafeDisc Results: Euro 2000 (Total: 257982 sectors - 10141 bad sectors) - Reading Speed: Max

The Sony CRX200E had the same performance with both pressed and cdr media. Its performance is not bad but not as good as what PleXWriter PX-W1210A can deliver.

b) LaserLock Results: Rally Masters (Total: 321528 sectors - 6317 bad sectors) - Reading Speed: Max

In the LaserLock protected CDs test, the Sony drive achieved the second best performance in both tests with pressed/cdr media.

c) SecuROM Results: Vrally2 Expert - 343767 sectors

The Sony CRX200E can read SubChannel data and, as the test results show, fast enough!
