A system administrator is given a server with an existing OS installed and four empty SAS bays. The system administrator is asked to set up a new data drive for testing with 100GB of data. For the…

SCSI is a legacy parallel interface standard that predates SAS and does not fit natively in SAS drive bays, and spinning SCSI drives are far slower than SSDs.

SATA drives have lower maximum bandwidth and higher latency than SAS-attached SSDs, making them a suboptimal choice when best possible performance is required.

A solid state drive (SSD) eliminates all mechanical latency because it has no spinning platters or moving read heads, resulting in microsecond access times and dramatically higher IOPS compared to any spinning-disk alternative. SSDs are available in SAS form factors and connect natively to SAS backplanes, fitting the available bays without adapters. For a 100GB test dataset where speed is the priority, flash storage provides a decisive performance advantage over every other option listed.

A USB flash drive is a consumer-grade removable device that cannot be installed in SAS bays and offers far lower throughput, higher latency, and less reliability than a server-grade SSD.
