SATA (Serial ATA) drives provide the highest storage capacity at the lowest cost per gigabyte among the listed options, making them ideal when budget and capacity are the primary concerns. They operate at lower RPM than SAS or FC drives, which limits I/O throughput, but this tradeoff is acceptable for a low I/O file server. SATA is the standard choice for cost-effective, high-capacity bulk storage in scenarios where performance demands are modest.

Fibre Channel (FC) drives are enterprise-grade, high-performance storage devices used in SANs that carry a significant cost premium, making them unsuitable when budget is a primary concern.

Parallel SCSI drives are older technology with lower capacity ceilings and higher per-unit costs compared to SATA, making them a poor choice when capacity and budget are the top priorities.

SAS (Serial Attached SCSI) drives are designed for high I/O enterprise workloads and cost significantly more per gigabyte than SATA, which conflicts with the budget and capacity requirements stated.
