Description
Storage Capacity and Data Transfer Rate
The storage capacity of the HPE 781581-004 is 300 GB, which means it can store up to 300 billion bytes of data. This is a relatively small capacity compared to modern hard disk drives, but it is still sufficient for many storage-intensive applications.
The data transfer rate of the HPE 781581-004 is 300 MB/s (megabytes per second), which refers to the maximum amount of data that can be transferred from the disk to the host computer in one second. This transfer rate is relatively fast for a hard disk drive, and it is suitable for many applications that require high-speed data transfer. However, for extremely demanding applications, a solid-state drive (SSD) with even higher transfer rates may be a better choice.
Performance and Speed of the HPE 781581-004
The HPE 781581-004 is a 10,000 RPM hard disk drive, which is considered to be fast compared to traditional 7200 RPM hard drives. This high spindle speed allows for faster data access times, which can improve the overall performance of the system.
The average seek time of the HPE 781581-004 is 4.16 ms (milliseconds), which refers to the average time it takes for the disk head to locate and access a specific piece of data. A low seek time is desirable as it means that the disk can access data more quickly.
The average latency of the HPE 781581-004 is 2.0 ms, which is the average time it takes for the disk to rotate under the disk head and position the data for reading. A low latency means that the disk can deliver data more quickly.
The cache size of the HPE 781581-004 is 16 MB, which is a buffer memory that is used to store data temporarily. A larger cache size can improve the performance of the disk by allowing it to quickly access frequently used data.
Compatibility with Enterprise Storage Systems
The HPE 781581-004 is compatible with enterprise storage systems because it uses the SAS (Serial Attached SCSI) interface, which is a popular interface used in enterprise-level storage systems. SAS provides high-speed data transfer rates and reliable data communication, making it suitable for demanding storage applications.
Additionally, the HPE 781581-004 has Advanced Error Correction Code (ECC), which helps to ensure data integrity and reliability in storage systems. This is particularly important for enterprise storage systems that store large amounts of critical data.
