Why each option

To store old data that needs to remain available for reporting, the most cost-effective and suitable disk type is one that offers high capacity at a low cost per gigabyte.

AFC

FC (Fibre Channel) drives are high-performance, high-cost disks typically reserved for primary storage that requires maximum I/O operations per second (IOPS), which is not a requirement for 'old data for reporting.'

BSATACorrect

SATA (Serial Advanced Technology Attachment) drives provide high storage capacity at a significantly lower cost per gigabyte compared to other options, making them ideal for storing older, less frequently accessed data that still needs to be available for reporting without requiring high-performance access.

CSSD

SSDs (Solid State Drives) offer extremely high performance and low latency but are the most expensive per gigabyte, making them an unsuitable and uneconomical choice for storing old data that is not performance-critical.

DSAS

SAS (Serial Attached SCSI) drives offer better performance and reliability than SATA but come at a higher cost, making SATA a more economical choice when the primary concern is storing large amounts of 'old data' for reporting with less stringent performance demands.
