LiteOn SOHW-1213S

2. Transfer Rate Reading Tests

LiteON SOHW-1213S Dual DVD±RW Recorder - Page 2

Transfer Rate Reading Tests

- CD Format

The LiteOn SOHW-1213S supports up to 48X reading speed. Below are the transfer rate graphs:

the LiteOn is slightly faster compared with the Plextor drive but the Plextor is faster with rewritable media offering 40X reading speed.

- DVD Format

The SOHW-1213S was slower than the Plextor drive when using PTP single layer DVD-ROM media.

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, towards the outer range, for each layer. The SOHW-1213S times were about 33% slower than the Plextor's times.

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 of 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 toward the inner part of the disc. The average reading speed is 6.01X.

With DVD+R media the SOHW-1213S is slightly faster compared with the Plextor while with DVD-R/RW and DVD+RW media Plextor is faster about 3X transfer rate speed.

The LiteOn reached 7769 kb/s, a good ripping transfer rate.
