What this lesson covers
In this episode, we review the most common storage interface types and their technical characteristics. Serial Attached SCSI (SAS) is explained as a high-performance, enterprise-grade interface, while Serial ATA (SATA) is presented as a cost-effective solution for standard server storage. We also cover external SATA (eSATA) for direct-attached storage expansion and USB for portable or temporary storage needs. Each interface is analyzed in terms of speed, cable length, connector type, and use case.
