Is Liteon Ldw-451s Better Then Ldw-411s?

Hi guy,IS LITEON LDW-451S BETTER THEN LDW-411S?Thanks!

Define “better”.
We think it has a different pick up head, and some folks have reported that the 451 has improved reading quality. Beyond that, not enough of the drives have been tested to really know much.
There’s a rumor that there may even be additional models coming out with still different PUH, both 8x and 4x versions.

If your question is which version to buy, I’d say get the 451, unless bit-setting is an issue.
