The next test, writing a DVD from a 3.5GB ISO image using ImageBurn:
As you can see from the above images, the SATA drive has a smooth progressive rise in writing speed (yellow line) as it nears the outer edge of the disc, with the buffer level (white line) and disc speed (green line) stable throughout the whole test. The IDE drive however seems to have an issue when it hits around 11X write speed, with the buffer level fluctuating greatly and thus causing the write speed to become erratic and much slower.
The drive seems to slowly drop the RPM down until the data rate becomes more stable and it continues writing with the disc at a lower RPM. This problem causes an additional minute or so to be added to the total burning time. This may indicate a data throughput/speed issue with the IDE connection, while the SATA connection has bandwidth to spare. This really shouldn’t be the case, because at 11X speed, it’s only transferring around 15MB/s, which wouldn’t be maxing out any IDE connection, even the old ATA33 standard.
