Transfer Rate Reading Tests

- CD Format

The TDK 1616N supports up to 48X reading speed. Below are the transfer rate graphs along with the comparison with the Pioneer DVR-108 drive:

The TDK 1616N proved to be faster than the Pioneer model with Pressed CDs, CD-R media and US-RW media.

- DVD Format

When pressed single layer media was used, the Pioneer DVR-108 and TDK 1616N reported similar reading speeds.

The two layers of a PTP DVD-ROM disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer, progressing towards the outer range for each layer. The TDK 1616N was slower than the Pioneer DVR-108 with a noticable difference in speeds.

The first layer of an OTP dual layer DVD-ROM is read exactly the same way as the first layer of the PTP disc we tested previously. The difference here is the reading strategy of the second layer on the disc. The beginning of the second layer is located in the outer part of the disc, so the drive starts reading from the outer tracks towards the inner part of the disc. The average reading speed was 5.43X with a start speed of 3.01X and end speed of 7.23X. These speed values indicate minor variations from the speeds reported by the TDK 882N drive, and are lower than the DVR-108 speed values.

The TDK 1616n can read DVD ±R media up to 16X and DVD ±RW up to 8X. That makes the TDK 1616n one of the fastest readers for ±R media. The Pioneer DVR-108 cannot compete with 8X CAV reading speed for all DVD recordable/re-writable media.

The TDK 1616N reported an average ripping speed of 5125kb/sec with DVD-Video discs, and proved to be slower than Pioneer's drive when it comes to DVD Video ripping.
