Hi,[QUOTE=bevills1;1917374]In my experience USB 2.0 doesn’t help that much.[/quote]Without USB 2.0, you can’t even burn at 1x. Results after hours will mostly be coasters.
I had a 750 MHZ desktop that took just over an hour to shrink and encrypt even with USB 2.0 card added,
Shrinking and encrypting is even possible without any drive attached;) Only CPU is, what matters here. For reading and burning with an external drive, a good USB 2.0 Hi Speed controller is mandatory.
check to be sure DMA is enabled which will greatly imporve burn speed if DMA is not enabled.
DMA does not matter with external drives. It does matter for the HDD, but this is something, that should be detected quite soon since the overall system performance is extremely poor then.
I heard somewhere 1400 MHZ or higher is needed for decent speeds with optical drives, and I believe that after my experience.
This is, what drive manufacturers write into their specs tables. These 1400 MHz are meant to be an indicator for a computer generation that has sufficient overall performance. Also some features of the bundled software package might really need at least such a CPU (video encoding or similar). For plain DVD burning, even a 600 MHz CPU is sufficient. Admitted, much more than 8x won’t be feasible with such old systems.
