300 GB IDE Ultra ATA133 desktop drive

This Maxtor MaXLine III 7L300R0 is a 300 GB 3.5-inch internal hard drive built for desktop computers that use the IDE Ultra ATA133 interface. It spins at 7200 RPM and includes a 16 MB cache for responsive data access. The bare-drive unit is supplied new and carries RoHS compliance.

Suits legacy parallel ATA systems.

Builders maintaining or upgrading older desktops and servers that require a Parallel ATA connection will find this drive a direct fit. Systems that have moved to later bus types cannot use this unit without an adapter. The 300 GB capacity also limits its usefulness for large modern workloads.

IDE Ultra ATA133 interface decides compatibility

The single specification that determines whether this is the correct part is the IDE Ultra ATA133 / ATA-7 interface. If the motherboard or controller provides that exact connection the drive will install and operate at its rated 7200 RPM with 16 MB cache. Any other interface makes the drive incompatible.
