Capacity and interface

This 20 GB IDE Ultra ATA133 hard drive spins at 7200 RPM with a 2 MB cache. It suits legacy desktop systems or industrial equipment that still rely on parallel ATA connections. The 3.5 inch form factor fits standard drive bays in older chassis.

Host compatibility check

Verify that the motherboard or controller provides an IDE Ultra ATA133 port and that the BIOS recognises drives of this capacity. Ensure a free 40-pin data cable connector and a Molex power lead are available before ordering. The bare-drive packaging includes no cables, brackets or mounting screws.

Sustained operation behaviour

Average seek time is 10 ms and average latency is 4.17 ms, giving predictable access during long copy or backup jobs. Maxtor Shock Protection and Data Protection Systems help maintain data integrity when the drive runs continuously in a fixed installation.

Questions about this item

Does the Maxtor 6E020L0 ship with cables, brackets or mounting screws, or do I need to source them separately?

This is a bare drive, so only the hard drive itself is included; IDE data cables, power adapters and mounting screws must be obtained separately.

The model shows 20 GB capacity and 2 MB cache — is that the only configuration available for the DiamondMax Plus D740X series?

The listed model 6E020L0 is a single 20 GB variant with 2 MB cache; other capacities or cache sizes would carry different model numbers.

With a 7200 RPM spindle and 10 ms average seek time, what kind of real-world throughput can I expect on an ATA-133 bus?

The drive sustains up to 133 MB/s on the Ultra ATA133 interface, while the 7200 RPM speed and 10 ms seek deliver responsive access for typical desktop workloads.
