Description
Enterprise Hard Drive
The Dell AA715977 16TB 7.2K RPM SAS 12GBPS 256MB Hard Drive is an enterprise-class hard drive designed for use in data centers, servers, and other high-demand applications. It has a SAS interface and a 12 Gb/s data transfer rate, which is faster than the SATA interface and 6 Gb/s data transfer rate of the previous model mentioned.
The SAS interface provides a higher level of data integrity and reliability and is typically used in enterprise-class servers and storage systems. The drive also has a large capacity of 16TB which makes it suitable for large data storage needs. Additionally, the drive has a 256MB cache which can help to improve performance by storing frequently accessed data.
It is important to check the compatibility with the specific server or storage system you plan to use it in, as SAS interface is not compatible with SATA interface, and it requires a specific controller to be able to communicate with the drive.
Serial-Attached SCSI
The Dell AA715977 16TB 7.2K RPM SAS 12GBPS 256MB Hard Drive uses the SAS (Serial Attached SCSI) interface, which is a high-performance and high-availability data storage interface designed for use in enterprise-class servers and storage systems. SAS is a point-to-point interface, which means that each drive has its own dedicated connection to the host controller, unlike SATA which is a shared bus interface. This provides a higher level of data integrity and reliability and allows for faster data transfer rates, in this case, 12 Gbps.
SAS also supports advanced features such as dual-ported drives, which provide redundancy and failover capabilities, and multiple initiators and targets, which allow for multiple hosts to access the same drive or multiple drives to be accessed by a single host. These features make SAS well suited for high-demand applications such as data centers and enterprise-class servers.
It’s also worth mentioning that SAS drives are generally more expensive than SATA drives, but the improved performance and reliability make them a good choice for critical applications that require high uptime and data integrity.
Drive Compatibility
The compatibility of the Dell AA715977 16TB 7.2K RPM SAS 12GBPS 256MB Hard Drive will depend on the specific computer or server that you are planning to use it with. It is a 3.5-inch internal hard drive, which means it is designed to fit in a standard 3.5-inch drive bay in a desktop computer or server.
However, the drive uses the SAS interface, which is not compatible with the SATA interface used by most consumer-grade computers and servers. Therefore, it requires a SAS controller to communicate with the drive and connect it to the host system. Most enterprise-class servers and storage systems have built-in SAS controllers, but you may need to purchase an add-on SAS controller if you are planning to use the drive in a consumer-grade computer or server.
It is also important to ensure that the server or storage system supports 12 Gb/s data transfer rate. Additionally, the drive has a large capacity of 16TB, and it may be necessary to check the maximum capacity supported by the server or storage system.
It is always best to consult the documentation for your specific computer or server to ensure compatibility before purchasing this product hard drive.
