40 GB IDE drive for legacy desktops

This 3.5 inch desktop internal hard drive delivers 40 GB of storage through an IDE interface. It spins at 7200 RPM with a 2 MB cache buffer. The unit is supplied new and carries a five year limited warranty from the manufacturer.

Suits vintage systems needing IDE storage

The drive fits older desktop chassis that accept a 3.5 inch low profile form factor of 1.0 inch height. It is intended for enterprise storage workloads on legacy platforms. Builders who need a larger capacity, a bigger cache buffer, or a different interface should look elsewhere.

The IDE interface decides compatibility

Only motherboards with an IDE controller can use this drive. The Ultra ATA 100 specification sets the maximum transfer rate for the connection. Verify that your system provides an IDE port before purchasing.

Questions about this item

How can I confirm the ST340016A is spinning at 7200 RPM after installation?

Listen for the characteristic 7200 RPM whine and verify the BIOS or operating system reports the full 40GB capacity and correct model number ST340016A.

Does the ST340016A ship with mounting screws, an IDE cable or a power adapter?

The drive itself is supplied in retail or OEM packaging; mounting screws, a 40-pin IDE cable and a Molex power lead must be sourced separately.

Which capacity version of the ST340016A should I choose for a legacy enterprise storage array?

This model is offered only in the single 40GB capacity with 2MB cache and 7200 RPM, so there is no alternative version to select.
