SG0-001 · Question #133
An administrator is tasked with selecting new storage architecture. The company values data transfer speeds over capacity. Which of the following should the administrator select for MAXIMUM throughput
The correct answer is B. SAS-2. For maximum throughput in storage architecture, SAS-2 offers significantly higher data transfer speeds compared to iSCSI, Fibre Channel, or older SATA versions.

Why each option
For maximum throughput in storage architecture, SAS-2 offers significantly higher data transfer speeds compared to iSCSI, Fibre Channel, or older SATA versions.
Gigabit iSCSI operates at 1 Gbps, which is significantly slower than SAS-2 (6 Gbps).
SAS-2, referring to 6Gbps SAS, provides a maximum throughput of 6 Gbit/s per lane, which is substantially faster than Gigabit iSCSI (1 Gbps), 2Gb Fibre Channel (2 Gbps), or SATA2 (3 Gbps), making it the optimal choice for maximum throughput.
