Questions about this item
How much noise and heat does the 7200 RPM ST3300820ACE produce during continuous DVR recording?
Seagate SoftSonic motor technology and optimized seek profiles are designed for years of quiet operation, while DynaPlay technology includes power optimization for the demanding DVR environment.
What host interface must my system provide for the IDE Ultra ATA 100 connection on this 3.5 inch drive?
The drive requires a standard 40-pin PATA/IDE controller capable of Ultra ATA 100 transfers; a Molex power connector is also needed for the 3.5 inch form factor.
Will the ST3300820ACE work alongside an older IDE drive on the same cable without performance loss?
Each drive on a shared IDE cable negotiates its own Ultra ATA 100 mode, so the 7200 RPM unit retains its throughput while an older device runs at its lower supported speed.
