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.
