4.55GB Ultra2 SCSI 7200 RPM MR Heads Factory Sealed

Why the ST34573LW is the right Legacy Enterprise HDD

The Barracuda 9LP represents Seagate's late 1990s enterprise SCSI technology, featuring the first generation of magnetoresistive heads for improved data density and reliability. With Ultra2 SCSI LVD interface supporting up to 80MB/s transfer rates, this drive delivered exceptional performance for its era. Originally designed for high-end workstations and servers, it remains essential for vintage system restoration and legacy application support where original SCSI hardware is required.

Ultra2 SCSI LVD Performance

The 68-pin LVD interface delivers up to 80MB/s transfer rates with improved signal integrity over longer cable runs. Ideal for enterprise systems requiring reliable high-speed SCSI connectivity.

7200 RPM Enterprise Speed

Fast 7200 RPM spindle speed with 8.5ms average seek time provided excellent performance for late 1990s enterprise applications. 512KB cache buffer optimizes data throughput for demanding workloads.

Magnetoresistive Head Technology

First-generation MR heads enable higher data densities and improved read sensitivity compared to earlier inductive head designs. Dedicated landing zone prevents head crashes during power cycles.

Legacy System Compatibility

Essential for vintage Sun, SGI, and HP workstation restoration projects where original SCSI drives are no longer available. Maintains authentic system performance and compatibility.

New Old Stock with 90-Day Warranty

Available as brand new, factory sealed old stock units from Anand International with a 90-day warranty. Ideal for legacy system maintenance, vintage computing restoration, and hard-to-find replacement needs.

Frequently Asked Questions

Frequently asked questions for SCSI, including information on usage, configuration, and compatibility.

1. What is a SCSI hard drive?

A SCSI (Small Computer System Interface) hard drive is a legacy enterprise storage device that connects using parallel ribbon cables. SCSI was widely used in servers, workstations, and storage arrays before newer technologies like SAS and SATA became standard.
2. What systems are SCSI hard drives compatible with?

SCSI drives are designed for older servers, RAID controllers, and storage arrays that have SCSI interfaces. They are commonly used today to maintain or repair legacy IT infrastructure.
3. What’s the difference between SCSI and SAS?

SCSI uses parallel communication and bulky ribbon cables, with speeds up to 320 MB/s. SAS (Serial Attached SCSI) is the modern successor, offering serial communication, smaller connectors, dual-port redundancy, and speeds up to 24 Gb/s.
4. Can SCSI hard drives still be used in modern systems?

Most modern computers don’t have SCSI ports. To use a SCSI drive, you’ll need a compatible SCSI controller card or an external enclosure designed for parallel SCSI.
5. What capacities are available for SCSI hard drives?

SCSI hard drives were typically available in capacities ranging from a few gigabytes to several hundred gigabytes. Larger capacities are rare compared to modern SATA and SAS drives.
6. Are SCSI hard drives hot-swappable?

Yes, many SCSI drives used in enterprise servers were hot-swappable when paired with a compatible RAID backplane or enclosure. This allowed replacement without shutting down the system.
7. Why are SCSI hard drives still used today?

SCSI hard drives remain important for maintaining legacy servers, specialized equipment, and industrial systems where upgrading to newer storage technologies isn’t possible or practical.
