LiteOn iHOS104 4x BD-ROM

4. DVD reading

DVD-ROM SL media

LiteOn iHOS104 LiteOn DH-4O1S Pioneer BDC-202
Average Speed 6.05x 9.10x 9.42x
Random access time 129ms 110ms 151ms

The LiteOn iHOS104 drive supports 8x for reading, making it a little bit slower than its competitors as you can see in the above table.

PTP DVD-ROM

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 its outer range.

Average Speed 6.14x 6.15x 6.27x
Random access time 126ms 124ms 164ms

OTP DVD-ROM

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 and progresses towards the inner part of the disc.

DVD Ripping speed

Ripping of a single layer DVD movie:

  LiteOn iHOS104 LiteOn DH-4O1S Pioneer BDC-202
Average 8.013 KB/s (5.8x) 8.19 KB/s (5.9x) 5.206 KB/s (3.75x)
Maximum 11.214 KB/s (8.1x) 11.36 KB/s (8.2X) 7.244 KB/s (5.22x)

Summary

LiteOn iHOS104 is not that fast as the other drives when reading DVD-ROM SL media. So if speed is what you are seeking of, you may add this to the list of negatives for the drive. However, we think that the drive generally performed pretty well while it was also fast in accessing the discs, compared to the Pioneer drive.
