Description
Capacity and Performance
“Capacity and Performance” refers to the storage capacity and the speed at which data can be read and written to the hard drive. In the case of the HPE 793669-B21 SC SAS 12GBPS 4TB 7.2K RPM LFF Internal Hard Drive, the capacity is 4TB and the speed is 12GBPS. The rotational speed of 7.2K RPM means that the hard drive platters rotate at 7200 revolutions per minute which allows the drive to quickly access data stored on the platters. The faster the rotational speed, the faster the drive can access the data. The SAS interface provides a faster data transfer rate compared to other interfaces like SATA, which makes it ideal for use in enterprise environments where large amounts of data need to be accessed quickly. Additionally, SAS interface also provides more advanced features such as dual-port connectivity which increases reliability and allows for multiple initiators to connect to the same target drive.
Data transfer rate and cache size
“Data transfer rate and cache size” refer to the speed at which data can be transferred to and from the hard drive and the amount of memory on the drive that is used to temporarily store data for quick access. The data transfer rate for the HPE 793669-B21 SC SAS 12GBPS 4TB 7.2K RPM LFF Internal Hard Drive is 12GBPS, which is a measure of the amount of data that can be moved to or from the drive in a given period of time. This high data transfer rate is suitable for high-performance applications such as data warehousing, scientific simulations, and video editing. The cache size is the amount of memory on the drive that is used to temporarily store frequently accessed data. A larger cache size allows the drive to access data more quickly, which can improve overall drive performance. The cache size of this drive will be specified by the manufacturer.
Interface and compatibility
“Interface and compatibility” refer to the type of connection used to connect the hard drive to the host computer or device and the types of systems and devices the hard drive is designed to work with. The HPE 793669-B21 SC SAS 12GBPS 4TB 7.2K RPM LFF Internal Hard Drive uses the SAS (Serial Attached SCSI) interface, which is a high-speed data transfer interface that supports faster data transfer rates and is commonly used in enterprise-level storage systems and servers. This hard drive is compatible with HPE ProLiant servers, HPE storage arrays and other SAS enabled systems. Additionally, this hard drive is also compatible with LFF (large form factor) internal bays, which is a type of drive bay that can accommodate larger hard drives. This allows for more storage capacity within the same physical space.
