Out of the options given, the best choice for maximum performance in a disk array that will host continuous disk-to-disk replication is SAS (Serial Attached SCSI).
Here's why:
USB: Universal Serial Bus (USB) is not an appropriate storage type for a disk array as it's primarily designed for peripheral devices like keyboards, mice, and printers. While USB storage devices are relatively inexpensive and widely available, they are not suitable for high-performance storage requirements like those needed for continuous disk-to-disk replication.
SCSI: Small Computer System Interface (SCSI) is an older technology that is still in use in some legacy systems. SCSI is capable of delivering good performance, but it's not as fast as newer technologies like SATA and SAS. Additionally, SCSI can be expensive and difficult to implement, especially when compared to SATA and SAS.
SATA: Serial Advanced Technology Attachment (SATA) is a popular storage technology that is commonly used in desktop and consumer-grade applications. SATA drives are affordable, widely available, and offer good performance for most applications. However, SATA is not the best choice for high-performance storage requirements like those needed for continuous disk-to-disk replication.
SAS: Serial Attached SCSI (SAS) is a high-performance storage technology that is designed for enterprise-grade applications. SAS drives offer faster data transfer rates, greater reliability, and better scalability than SATA drives. Additionally, SAS drives support features like dual-porting, which allows for redundant data paths and better fault tolerance. SAS is the best choice for high-performance storage requirements like those needed for continuous disk-to-disk replication.
In summary, SAS is the best choice for maximum performance in a disk array that will host continuous disk-to-disk replication, as it offers faster data transfer rates, better reliability, and greater scalability than other storage types like USB, SCSI, and SATA.
