Seagate BarraCuda 7200.9 300GB IDE drive

This new Seagate ST3300622A is a 300GB 3.5-inch internal hard drive built for desktop PCs that still use the IDE Ultra ATA100 / ATA-6 interface. It spins at 7200 RPM with a 16MB cache and delivers 4.16ms average latency for general storage tasks.

Suits legacy IDE desktops only

Buyers maintaining or repairing older computers with an available IDE Ultra ATA100 / ATA-6 connector will find the correct form factor and interface here. Systems that require a different drive interface cannot use this unit, and anyone needing more than 300GB of capacity should consider other options.

IDE Ultra ATA100 / ATA-6 interface

The single specification that determines compatibility is the IDE Ultra ATA100 / ATA-6 interface; the motherboard or controller must provide this exact connection for the drive to function.

Questions about this item

How do I install the ST3300622A and set the master or slave jumper correctly?

Connect the 40-pin IDE cable to the drive and motherboard, attach a 4-pin Molex power connector, then set the jumper block on the rear to Master for a single drive or Slave if sharing the cable; the drive is a bare 3.5" unit so it mounts in a standard bay with four screws.

What maintenance or replacement will the BarraCuda 7200.9 need over time?

No scheduled maintenance is required; the 16MB cache and mechanical parts are sealed, so the only future action is replacing the drive if SMART attributes report reallocated sectors or if the 63 Gs operating shock limit is exceeded.

What is the first limit reached during sustained heavy writes on this 300GB model?

The IDE Ultra ATA100 interface caps sustained throughput at 100 MB/s, so the bus saturates before the 7200 RPM platters or 4.16ms average latency become the bottleneck.
