SG0-001 · Question #154

Which of the following is BEST suited for seldom accessed data but needs to be retrieved in less then one minute from the time of the request?

The correct answer is C. SATA disks. SATA disks are best suited for seldom-accessed data requiring quick retrieval due to their balance of cost, capacity, and acceptable access speeds.

Why each option

SATA disks are best suited for seldom-accessed data requiring quick retrieval due to their balance of cost, capacity, and acceptable access speeds.

ATape

Tape storage is very low cost and high capacity for archival data but has significantly slower access times, typically measured in minutes or hours for retrieval, which does not meet the 'less than one minute' requirement.

BSolid State disks

Solid State Disks (SSDs) provide very high performance and low latency, making them suitable for frequently accessed data, but they are more expensive per gigabyte than SATA, making them less cost-effective for seldom-accessed data.

CSATA disksCorrect

SATA (Serial Advanced Technology Attachment) disks offer a good balance of high capacity and lower cost per gigabyte compared to SSDs or SAS, making them ideal for storing large amounts of infrequently accessed data. While not as fast as SSDs or SAS, their retrieval times are typically in milliseconds, easily meeting the 'less than one minute' requirement.

DSAS disks

SAS (Serial Attached SCSI) disks offer higher performance, reliability, and enterprise features than SATA, making them suitable for critical, frequently accessed data, but they are generally more expensive than SATA and overkill for seldom-accessed data.
