Description
SAS interface and transfer rate
The SAS (Serial Attached SCSI) interface and transfer rate refer to the way that the hard drive connects to and communicates with the host system. The HPE 782669-B21 6TB 7.2K RPM SAS 6GBPS Smart Drive Carrier SC Hard Drive With Tray uses the SAS interface with a 6 Gb/s (Gigabits per second) transfer rate.
The SAS interface is a type of data storage interface that uses a serial signaling technology to transfer data between devices. It is commonly used in enterprise-level storage systems and servers, and is known for its high data transfer rates, scalability, and reliability.
The transfer rate of 6 Gb/s refers to the maximum data transfer rate that can be achieved over the SAS interface. This means that the hard drive can transfer data to and from the host system at a maximum rate of 6 Gb/s, or roughly 600 MB/s (MegaBytes per second).
It is important to note that the actual data transfer rate will depend on several factors, including the system’s hardware and software configuration, the workloads running on the system, and the condition of the hard drive. Also, the hard drive’s performance can be affected by the host controller, backplane or system that the drive will be installed in, has a SAS interface that is compatible with the hard drive and the SAS interface can be also backward compatible with 3 Gb/s and 1.5 Gb/s SAS devices.
Spindle speed and cache size
The spindle speed and cache size are two important factors that affect the performance of a hard drive.
Spindle speed, measured in revolutions per minute (RPM), refers to the speed at which the hard drive’s platters (the disk-shaped surfaces that store data) spin. The HPE 782669-B21 6TB 7.2K RPM SAS 6GBPS Smart Drive Carrier SC Hard Drive With Tray has a spindle speed of 7200 RPM. This is considered to be a standard speed for enterprise-class hard drives and provides a good balance between performance and power consumption. In general, the higher the RPM, the faster the hard drive can access data, but also it may consume more power.
Cache size, measured in megabytes (MB), refers to the amount of memory on the hard drive that is dedicated to storing frequently accessed data. This allows the hard drive to quickly retrieve the data without having to access the platters, which can significantly improve performance. The cache size of the HPE 782669-B21 6TB 7.2K RPM SAS 6GBPS Smart Drive Carrier SC Hard Drive With Tray is not specified by the vendor but as a general rule, the higher the cache size, the better the performance of the hard drive.
It’s important to note that the spindle speed and cache size are not the only factors that affect the performance of a hard drive, the interface and the transfer rate, the drive’s capacity, the workloads running on the system, and the condition of the hard drive can also have an impact on performance.
HPE ProLiant Server Compatibility
HPE ProLiant servers are a line of enterprise-class servers developed by Hewlett Packard Enterprise (HPE). The HPE 782669-B21 6TB 7.2K RPM SAS 6GBPS Smart Drive Carrier SC Hard Drive With Tray is designed to be compatible with HPE ProLiant servers. This means that the hard drive can be installed and used in these servers without any additional hardware or software modifications.
However, it is important to note that not all HPE ProLiant servers are compatible with the hard drive. It is recommended to check the specific server model and its technical specifications to ensure compatibility. Additionally, it is a good practice to check the server’s firmware version and update it to the latest version before installing a new hard drive.
Some of the HPE ProLiant servers that are compatible with the hard drive include the HPE ProLiant DL380 Gen9, HPE ProLiant DL360 Gen9, HPE ProLiant DL560 Gen9 and HPE ProLiant DL580 Gen9 servers, among others.
It’s also important to check if the hard drive’s form factor, interface and transfer rate is compatible with the server’s bays, backplane or host controller and if the hard drive has the necessary firmware or jumpers to be compatible with the server.
