BarraCuda 7200.10 320 GB IDE drive
This 3.5 inch desktop hard drive uses the IDE Ultra ATA100 interface and spins at 7200 RPM with a 16 MB cache. It suits owners of legacy systems that still rely on parallel ATA connections for primary storage or backup.
Interface limits at ATA-6
The Ultra ATA100 / ATA-6 bus tops out at 100 MB per second, so sustained throughput cannot exceed that ceiling regardless of platter speed. Average seek is 11 ms, average write is 12 ms and average latency is 4.16 ms, figures that reflect the mechanical constraints of the era.
Bare drive build and daily implications
The bare drive arrives without cables, brackets or mounting screws, so installers must supply their own 40-pin IDE ribbon and a spare 3.5 inch bay. Perpendicular recording and G-Force protection were designed for reliability in older chassis, while RoHS compliance confirms restricted substance limits.

Spørgsmål om denne vare
Which capacity of the Seagate ST3320620A should I pick for a desktop upgrade?
The drive is offered in a single 320GB capacity, so there is no choice to make — it fits any 3.5" bay that accepts an IDE Ultra ATA100 device.
What does the 7200 RPM spindle speed deliver once the drive is installed?
A 7200 RPM rotation rate combined with a 16MB cache yields an average seek time of 11ms and average latency of 4.16ms, giving responsive desktop performance on the IDE Ultra ATA100 bus.
What does the IDE Ultra ATA100 interface cap at in practice?
The ATA-6 Ultra ATA100 interface limits burst transfers to 100 MB/s, and real-world throughput will be lower due to the 7200 RPM mechanics and 11ms seek time.
