SAS drives, or Serial Attached SCSI drives, are a type of data storage device commonly used in servers and high-performance computing environments. They offer faster data transfer rates and improved reliability compared to traditional SATA drives. SAS drives are designed for enterprise applications, making them suitable for tasks that require quick access to large amounts of data. These drives typically operate at speeds of 6, 12, or 22 Gbps, allowing for efficient data handling. SAS drives also support multiple devices on a single connection, enhancing scalability. Their robust design ensures durability, making them ideal for critical applications in data centers and businesses.
