Samsung TS-H552U

2. Transfer Rate Reading Tests

Samsung TS-H552U Burner - Page 2

Transfer Rate Reading Tests

What follows in this section of the review, are the reading speeds of the three drives for pressed CD/DVD and R/RW media formats.

- CD Format

Results for CD media with pressed media, a copy on CD-R and HS-RW media....

The drive confirmed Samsung's stated specs, reaching in all cases its maximum reading speed, except with RW media...

- DVD Format

We repeated the same tests, this time with DVD media.

With DVD SL media, the drive once again confirmed its stated specs, though it didn't manage to achieve the title of the fastest drive in the comparison with the other two 16X drives, coming in second although the difference between all three drives is negligible.

Using PTP DL media (where the two layers of the disc are read sequentially with the drive starting reading from the inner part of the disc, which is the beginning of each layer), the drive reported the fastest reading speeds in the comparison as shown in the graph below.

The graph below indicates the reading performance of the TS-H552U with OTP dual layer media. While the first layer of the DL DVD is accessed by the drive in the same manner as with PTP DL media, with OTP DL media 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. Again the Samsung drive was fastest and times were very similar to those with PTP media.

The following two graphs include the reading performance with recordable and rewritable media, where the NEC drive reports the highest reading speeds for +R/-R (almost twice as fast as the Samsung) while the TS-H552U reported the highest speeds with RW media but not by a large margin compared to the other drives.

We ripped the contents of a pressed Double Layer movie to the hard disk with the Samsung drive. The results are summarized below:

High transfer rate for the Samsung TS-H552U drive.
