+SCSI

An acronym for Small Computer System Interface. SCSI is an interface that allows connection to a peripheral device, including RAIDs. Most SATA RAID & IDE RAID units from RaidWeb employ U320 SCSI connections, meaning the theoretical transfer rate is 320Mb/S.

+SMART

A hard drive technology that allows a RAID unit to provide an early warning of future data failure. The drive self-scans and reports the beginning of drive irregularities. This allows the user to replace a drive before data failure occurs. RaidWeb SATA RAID units utilize SMART technology.

+Storage Area Networking (SAN)

SAN is a term for a high-speed, scalable network of storage devices and servers, usually to acheive enhanced data transfer. RAID units are often integral parts of a SAN.

+Striping, Disk Striping

RAID technology that spreads data equally across all installed hard drives. This enhances data performance and provides redundancy at many RAID levels including RAID5.

+Throughput

The number of Input and Output (I/O) requests satisfied per second. Higher throughput equals higher data transfer. Throughput is dependant on many factors including hard drives utilized, server configuration, interface type, and more.

+Transfer Rate

The rate data is transferred between a RAID and host. Usually shown in Mb/s.

+VHDCI

An acronym for Very High Density Cable Interconnect. The connector on a VHDCI SCSI cable is much smaller than a typical SCSI 68 pin connection, allowing placement of more cables.
