Section 1. General description

Seagate ST43401N/ND and ST43402ND Elite 3 disc drives are high speed, random access digital data storage devices. They communicate with an initiator using the fast and wide (16-bit) Small Computer System Interface (SCSI-2). The ST43401N/ND disc drive is shown in Figure 1, and the ST43402ND (dual port) disc drive is shown in Figure 2. Specifications for these drives are listed in Table 1 following the figures.

The drive is a component for installation in an enclosure designed for the drive. The enclosure design must ensure adequate cooling for the drive, and it must address the requirements for grounding and for shielding of emissions. The reference manual (publication 83327730) presents guidelines for a properly designed enclosure.
