1 Year DiscTech - What does this mean?

The ST51080N is a high-capacity, high-performance, energy-efficient SCSI drive that comes in the mini 3.5-inch form-factor.

The drive uses a high-performance SCSI-2 interface that supports an asynchronous external transfer rate of up to 5 Mbytes per second and a synchronous external transfer rate of up to 10 Mbytes per second.

The interface is supported with a 128-Kbyte segmented cache and embedded servo technology. The segmented cache aids the flow of read and write data. The embedded servo allows for accurate positioning of the heads over the data and eliminates periodic thermal recalibration to assure data transfer without interruption.

The ST51080N conforms to the standard 3.5-inch footprint but have a 0.75-inch (19 mm) height profile and a 5.0-inch depth profile. The lower height and shorter depth gives the designer or integrator more room for air circulation, other peripherals or a smaller drive bay.
