BarraCuda 181.60 GB SCSI drive

The Seagate ST1181677LW is a 3.5-inch internal hard drive with a 7200 rpm spindle speed and 4 MB buffer. It uses an Ultra160 SCSI interface and offers 181.60 GB of storage capacity. The drive belongs to the long-running BarraCuda product line from a manufacturer founded in 1979.

Suits legacy SCSI servers and workstations

This drive fits systems that specifically require a 3.5-inch Ultra160 SCSI hard drive for replacement or expansion. It is not suitable for laptops despite the supplier category label, nor for any system lacking a compatible SCSI controller. Buyers who need higher capacities or solid-state speed should look elsewhere.

Ultra160 SCSI interface decides fit

The single specification that determines compatibility is the Ultra160 SCSI interface; the host must provide a matching SCSI bus and connector. Without that interface the drive cannot be installed or used.

Questions about this item

Does the ST1181677LW ship with mounting screws or cables, or must they be bought separately?

The drive is supplied in retail or OEM packaging that may vary; mounting screws and SCSI cables are not included and must be sourced separately.

The listing shows 181.60 GB — is that the only capacity available for this BarraCuda model?

This specific part number ST1181677LW is offered solely in the 181.60 GB capacity; other BarraCuda models carry different part numbers and capacities.

What does the 7200 rpm spindle speed mean for actual throughput on an Ultra160 SCSI bus?

The 7200 rpm rotation combined with a 4 MB buffer sustains typical sequential transfers near the Ultra160 SCSI bus limit of 160 MB/s in real workloads.
