SATA, SAS, AND RAID

 

 

As disk drive technologies continued their growth through the late 1990s, the parallel interfaces used by these storage devices could no longer support any further increases in data transfer rates and thus became impractical as a means of connectivity between hosts and disk storage components. The generational expansion of SCSI was fueled by quantum leaps in the development of higher capacity, higher speed, and higher performance storage in the form of spinning disks.

Parallel SCSI interfaces, formally called the SCSI Parallel Interface (SPI), as used in external drive connectivity would fade as the technical landscape was dramatically and radically transformed. As parallel SCSI approached its practical performance limits, ...
