36.7GB 15K RPM Ultra320 SCSI 80-Pin SCA 3.5-Inch Hard Drive

The ST336754LC is a high-performance enterprise hard drive from the Seagate Cheetah 15K.4 family, built for servers, storage arrays, and workstations that use an 80-pin hot-swap SCA Ultra320 SCSI interface. With a 15,000 RPM spindle speed, 8MB cache, and enterprise-class parallel SCSI performance, this drive was widely deployed across OEM platforms from Dell, HP, IBM, Sun, and other legacy server environments.

This model is designed for systems that require a 3.5-inch 80-pin SCA / hot-swap Ultra320 SCSI hard drive. It is not a SATA drive and it is not a SAS drive.

⚙️ Fit Notes

• This drive uses an 80-pin SCA hot-swap Ultra320 SCSI interface. It will not work in SATA systems.
• This drive is also not a SAS model. Please confirm your system uses parallel SCSI / Ultra320 infrastructure before ordering.
• Tray, caddy, firmware label, and OEM branding may vary depending on inventory lot and source unit.
• If your system requires a specific OEM tray, carrier, bezel, or firmware branch, please match the OEM spare part number as well as the base model number.
• Related family models with different interfaces may exist, but they should not be used as substitutes unless the connector and host interface are identical.
• Photo is for reference only. Actual label and top-cover markings may vary.
