Which type of disk is recommended for long-term storage of large amounts of data that is rarely accessed?

The recommended type of disk for long-term storage of large amounts of data that is rarely accessed is a SATA disk. SATA (Serial Advanced Technology Attachment) disks are designed to offer large storage capacities at a relatively low cost, making them ideal for use in scenarios where data is archived and infrequently accessed.

SATA disks typically have slower read and write speeds compared to other types such as SSDs (Solid State Drives) or even SAS (Serial Attached SCSI) disks. However, their cost-effectiveness and sufficient performance for read-heavy, infrequent access make them suitable for long-term data storage applications.

While other disk types like SAS and NL-SAS may provide better performance and reliability, they are usually optimized for scenarios that require faster data access and high performance, such as databases and transactional workloads. SSDs, while offering excellent speed and reliability, are often more expensive per gigabyte and are not typically necessary for data that will not be accessed frequently.

In summary, SATA disks strike a good balance between capacity and cost for long-term storage needs, making them the most recommended option for large volumes of seldom-accessed data.
