80 GB IDE Ultra ATA100 Desktop Drive

The Seagate BarraCuda 7200.10 ST380215A is an 80 GB 3.5-inch internal hard drive that spins at 7200 RPM with a 2 MB cache. It connects through an IDE Ultra ATA100 interface and is supplied as a bare drive. Average seek time is 11 ms and average latency is 4.16 ms.

Suits legacy IDE systems and upgrades

This drive fits desktop computers or external enclosures that still use a 40-pin IDE connector and need modest capacity. It is not suited to builds that require a Serial ATA connection, larger storage space or a higher cache allocation.

Interface and capacity limit

The single specification that decides compatibility is the IDE Ultra ATA100 interface combined with the 80 GB capacity; the motherboard or controller must support this legacy parallel interface for the drive to function.

Questions about this item

How often will the 2 MB cache need attention or replacement during the drive's life?

The 2 MB cache is built into the drive's controller board and has no separate maintenance schedule or replacement interval.

Which limit appears first during sustained transfers — the IDE Ultra ATA100 interface or the 7200 RPM platters?

The IDE Ultra ATA100 interface caps burst throughput at 100 MB/s, which is reached before the 7200 RPM mechanism can sustain higher rates.

How much heat and noise does the 3.5 inch, 1.0 inch high drive produce when running continuously?

The drive is described as whisper-quiet and its low-profile 1.0 inch height helps limit heat build-up during all-day operation.
