Blu ray burner for the first time in the test
If Samsung had still completely overslept the start of the DVD burners, the Koreans want to completely in front be at the next generation of the optical storage media also thereby and strike the Japanese competition of Sony & CO a Schnippchen. The drive assembly is already finished, one waits only for the new copy protection AACS , it was said. In order to support the statement, received the computer magazine c't an engineering SAM-polarize the BD burner Sh-b022 for one day to the test.
(The Sh-b022 presents itself with schicker black front screen. The ejection button flashes in the case of burning blue. )
The drive assembly can already describe Blu ray Discs. CDs and DVDs read it only. The sales version is to be able to burn it however also. Samsung supplied a special version of Nero with the version number 7.0.4. With this it succeeded to us to describe a again-recordable einlagige Bd-re25 with nominal 25 GByte storage location completely. If one counts on 1024 byte per kilobyte, then 22.23 GByte fit on a Disc. Two-part versions, which are so far not yet available, are to swallow the double.
The combustion with 2X (corresponds to a transfer rate of 8990 KByte/s) lasted 43:40 minutes. The drive assembly described but announced a once recordable blank (Bd-r) from the fundus of the editorship meanwhile not, that the mark was not supported by the write strategies in the firmware.
Our bench mark program h2benchw could address the drive assembly without problems and determined quite good transfer rates. A Bd-RH is picked out with on the average 8.6 MByte/s, a Dvd-9 with 6,0 MByte/s, an Dvd r with 11,6 MByte/s and an CD-r with 4,4 MByte/s. The middle access times moved between 259 ms with the Bd-RH and 114 ms with an CD-r. The error correction during the reading worked with a badly burned test DVD r very well and with one scratches test CD Rome well. Badly pressed Dvd Rome did not recognize the Sh-b022 however. With a scratched audio CD we heard starting from 1.2 mm scratch width of interferences, copy-protected music CDs however with an exception everything were already played.
At the back of the drive assembly Samsung inserted inside a small exhaust. The housing had however no ventilation openings and in such a way whirls the small Quirl air in the housing only in disorder, as soon as one inserts a Disc. The noises remain however nevertheless in pleasant ranges. With a BD it reaches 1.6 Sone, when playing a video DVD 1.9 Sone and with the selection CD Rome still very good 3.9 Sone.
With an earlier test of a Sony drive assembly for Professional Disc for DATA (the professional variant Blu ray of the Disc) the high temperature than very problematic emerged. The Samsung burner remains however cool. Directly after burning we measured uncritical 42 °C on the Discoberflaeche.
A view in the housing inside revealed the new technology. Thus Samsung on CONTROLLER chips of Sony trusts and into its Pickup Head two lenses built, one for CDs and DVDs and a larger for Blu ray the Discs. Rubber buffers intercept vibrations.
(The read-write head bring along two lenses, the upper small for CDs and DVDs, the lower large for Blu ray Discs. )
Result
Samsung goes as the first through the goal and presents the first functioning Blu ray burner outside from fairs and reglementierten conference rooms. The fact that we were allowed to move the test equipment without restrictions with our measuring tools, still in the development, to body witnesses of self-confident its the Korean. The Sh-b022 works already now better than so some Retail drive assembly. Sometimes we had to insert a Disc twice, before them were recognized, serious problems gave it however none.
The developers have still until April time to insert the missing functions. The finished drive assembly is to describe and to read be able then also two-part BDs with 50 GByte. To do also the software developers do not have some, except the special version of Nero wanted other program, which is alleged "Blu ray ready", with the drive assembly to co-operate. Only with the final sales devices one will see, how the new features of the Blu ray films in action look and whether the AACS was implemented error free.
Samsung already gives a Vorgeschmack, which hardware is needed for the Blu ray drive assembly with IDE connection, first: Thus one needs a 3-GHz-CPU and a diagram map with at least 128 MByte memory for the expenditure by hp films, to be recommended a Geforce 7800 or ATI Radeon X1800. so far gives it however no models, which exhibit the necessary copy-protected interfaces HDMI or DVI with HDCP. Without these one will be able to show the films if necessary in dissolutions of standard, but not in hp one will see in such a way the first drive assemblies, if they come according to Samsung starting from April on the market, probable in complete PCS with according to equipped OEM Grafikkarten. Samsung did not call a price for Europe so far, in the USA is the Sh-b022b 500 US dollar to cost.
