I own 2 QPS drives! Yes I dared to be different, and guess what? The QPS 24X IDE internal is awesome. Copied everything under the sun correctly. However, the QPS 16X firewire external is giving me some problems...IL2 sturmovik (see clonecd forum). Supposedly, both drives are Plextor rips and even use plextor firmware updates.
I would recommend the QPS 24X internal ($129 US). however, the Lite-on is cheaper (and it is $99 US).
The system that burned:
QPS 24x10x40 internal IDE
I don't know the innards of this computer that well, as I didn't really care at that time.
The system that won't:
AMD Duron 1Ghz
QPS firewire external 16x10x40
PC chips motherboard SiS735chipset
52X Samsung CDROM
Now I'm stuck deciding if I want to buy the Lite-On or just go for the gold and get the Plextor in the AMD system.
