You should also check in device manager, if your harddisk is running in Ultra DMA mode.
Okay. I just came home and wrote a DVD+R (Yuden T03)@12x.
Drive is Sony DW-G120A, connected via Cypress-based USB enclosure to VIA chipset. Except from the mainboard chipset, this is basically the same hardware as yours (If I want, I could flash Liteon FW).

The disc written above can be read at full speed, that means, the enclosure is not limiting the drive.
These TY T03 seem not to be top notch as the used to be
