Today, I received a dump of the 3450 firmware from Liggy and decided to do a crossflash of my 3500. Not that it is very usefull, but this way we can get some more information on this drive.
At another place in the forum, someone has pointed out that the 3450 simply is a rebadged 3100, so it should be highly hardware-compatible with the 3500.
Crossflashing went OK using the latest binflash, the reflash to 3500 also works OK.
Here are some reports from popular programs, after the crossflash to 3450:

So what does this learn us?

Quality scan will follow as soon as it's finished.
Summary so far:
If you would be satisfied with a stock 3500, you will be with the 3450. If you want higher burnspeeds, RPC1, Riplock removed or bitsetting, you can flash to any 3500 firmware and have no problems. But you have to use the newest version of Binflash, all other programs or earlier versions will reject the 3450 as "unknown".
