CR52-M: CDRW ramps up to 32X

Write Speeds

Moving on, we take a look at CDR write benchmarks:

The average write speed came to about 39.23X. While many drives perform upwards of 40X average write speeds on this benchmark, realistically, the second or two differences will not matter.

The CR52-M uses a magnetic head based on Partial CAV for the rewrite mode. The drive is locked to prevent the unit from producing a greater than 32X rewrite speed after it is obtained on CAV. Below are rewrite and write specs based on the same benchmark.

	Average Transfer	Media Length
PNY 52X CDR Data CD	39.32X	79.49.74
Verbatim 52X CDR Data CD	39.25X	79.49.74
Mitsubishi 32X CDRW Data CD	29.73X	73:43.00

One of the last tests we reserved for the CR52-M was the overburn media test. We used high quality PNY 48X 80min Type 6 CDRs, but sadly, it only obtained 82.51min of burn time. Even more disappointing, our drive locked up and would not let us kick the disk out. Instead, it just continued to blink and read the disk. Only a restart would eject our disk. While this is not an uncommon error in the optical media, we would have liked some error correction on MSI’s behalf. Below are the results that we obtained from our overburn test.

For those interested, we also took a measurement of Full Erase and Quick erase in Nero. For a 700MB Mitsubishi 32X CDRW, we obtained 3:20 for a full erase, and 0:26 for a quick erase. This makes it one of the fastest drives available strictly concerning erase times.
