The 161-BBHI Dell 4TB 7.2K RPM SAS-12GBPS NL 512n Hard Drive has a capacity of 4TB, which provides ample storage space for large data sets and multimedia files. The drive's 7.2K RPM rotation speed and 12GB/s SAS interface provide fast data access and transfer speeds, allowing for efficient data processing and retrieval. Additionally, the drive's 512n sector size and NL (non-linear) format enable high-performance data storage and retrieval.
the Dell hard drive offers a balance of capacity and performance for businesses and organizations that require large amounts of data storage and quick access to that data.SAS Interface and Data Transfer Rate
The 161-BBHI Dell 4TB 7.2K RPM SAS-12GBPS NL 512n Hard Drive uses a SAS (Serial Attached SCSI) interface for connectivity. SAS is a high-speed, high-performance interface that is designed for use in enterprise-level storage systems. It provides a 12 Gbps data transfer rate, which is faster than the 6 Gbps offered by SATA interfaces. This allows for faster data access and transfer, making it suitable for use in high-performance storage systems where data retrieval and processing speeds are critical.
Additionally, SAS interface supports full-duplex data transfer, allowing data to be sent and received simultaneously, which can further increase the data transfer rate, and also allows for better scalability and expandability by connecting multiple hard drives in a daisy-chain configuration. SAS interface also supports hot-swapping, which means that the hard drives can be replaced or upgraded without shutting down the system, which can be a crucial feature in enterprise environments.
Rotational Speed and LatencyThe 161-BBHI Dell 4TB 7.2K RPM SAS-12GBPS NL 512n Hard Drive has a rotational speed of 7200 RPM (revolutions per minute). This means that the drive's platters spin at a speed of 7200 times per minute, which can be critical in determining the drive's performance and overall data access speed. Generally, the faster the rotational speed, the faster the data can be accessed and retrieved. 7200 RPM is a standard speed for enterprise-level hard drives, and it offers a good balance of performance and power consumption.
Latency, also known as access time, refers to the time it takes for the drive's read/write head to access a specific piece of data on the platters. The latency of the drive is measured in milliseconds (ms) and is directly related to the drive's rotational speed. The Dell hard drive has a latency of 4.16 ms, which is considered to be low and offers fast data access.
Together, the 7200 RPM rotation speed and the low latency of 4.16 ms make this drive suitable for use in applications that require fast data access and retrieval, such as databases, virtualization, and high-performance computing.
