Conclusion
The F16 from Memorex is a fast CD reader with good seek times. We would like to see an improvement in the area of error correction, which was below average to average.

In the DVD reading tests, the drive displayed good performance, with error correction being very good this time. DVD ripping with DL pressed discs was also fast.

The performance of the drive when reading AudioCD's was very good. The reading speed was high while, according to Nero's Advanced DAE test, the drive qualified with a perfect score of 100. The good behavior continued with the protected AudioCD's which the Memorex F16 can read, rip and backup without problems.

Protected games backup is not a strong point of the F16 drive. However it did manage to make working backups of SafeDisk protected games up to v2.8.

The 48X recording speed for CD-R media is high and there are not too many recorders that support this speed in combination with the other features that the F16 has to offer. The writing quality at such speeds revealed slightly increased levels of C1 errors and some C2, while the Jitter levels were also increased. But we cannot condemn the drive keeping in mind that the safest CD recording is achieved mostly at 16X or 24X.

According to our DVD recording tests, the drive supports CAV strategy for the 16X DVD+R which is a good feature. The time needed for such writing is 5:45min, a rather low time. The recording speed for the DVD-R format could be higher than the currently supported 8X. As for the writng quality with both formats, this needs improvement. The reported PI/PIF levels, as they were reported with Kprobe and Plextools, were high. This is something that, with a newer firmware upgrade, will probably be fixed. Despite this, the writng quality for Double Layer media is very good.

Another imprortand issue that should be added in the drive's features is that of bitsetting. We expected it to be included, since the drive is LiteOn based. The produced burned disks, despite being of good writing quality, were not recognized in our standalone DVD players from Philips and Pioneer.

This drive can be used for DVD media error measurements, which is an advantage for the F16.

At the time of this review, the price for the retail package as posted on the Memorex website was US$149.99, which we consider pricy since there are other drives available on the market with similar specifications for below $100.

  • Doesn't support reading of DVD-RAM media
  • Retail package didn't include any DVD+R DL media

- Like to be fixed

  • DVD writing needs improvement, drive produces high PI/PIF error rates (could be fixed with firmware upgrade?)
  • Limited support media list for 16X/12X DVD+R writing
  • High C1/C2 errors with specific media at 48X
  • Retail price

 
It is likely that all Liteon 1633S drives and OEMs of will have similar results, the gremlins of the new chipset are still not worked out, though there have been SOME good results for the 1633s with BS0C firmware.

Strange that 4x burns apppear to show the zoning you'd expect on an 8x CLV burn (and it does use CLV for -R) - the error rates seem to jump right where the 8x shift would be executed - is this drive oversppeding 4x media without being asked, though that would show up in an 8x burn time?
