Samsung SH-B022 Blu-ray Writer Preview @ heise online

Postby Ian on Thu Jan 26, 2006 12:22 pm

Heise got their hands on a preproduction sample of Samsung's Blu-ray writer. Here's part of their preview (translated from German):


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.

The article also has pictures of the dual pick up heads. I recommend checking it out.

I'm not sure if they needed to go so far as test the error correction of the drive's CD and DVD hardware... since it states that in the final product it will be a burner/reader, it's quite likely the hardware tested in that preview is not indicative of what will be there in the end. Looks like the BluRay burning is right on track though :D

Since it was able to burn a 25GB disc in about 43 minutes, that's respectable. That's comparable to my NEC 3520A which takes 6 min to burn ~4.4GB. The win here is one disc instead of 6 DVD's. The $500 price + media price will have me wait a year or more.

Thanks Ian,

Just a bit more information that isn't babble-fished:
- they had the drive for one day only
- put it through the usual suite of reading tests (hence results on error correction)
- the successful burn was a single layer rewritable (25 GB or 22.23 GiB), using a special version of Nero (7.0.4)
- a one-time blank they had "flying around" didn't work (no burning strategy in the firmware)
- other burning apps didn't cooperate with the drive

They were pretty impressed with the drive and the confidence that Samsung showed in it- letting them poke around to their heart's desire in a device still in development.

There'll be a full report in the next c't (due in ca. 10 days).
