Description
More Specification
The Seagate 1GR221-251 10K.8 1.8TB SAS-12GBPS 128MB 512E Hard Drive is a high-performance storage solution designed for use in enterprise-level server and storage systems. It features a SAS interface with a 12 Gbps data transfer rate, a large 1.8TB capacity, and a fast 128MB cache for improved read and write speeds. Additionally, it supports the 512E format, which allows for increased storage density and compatibility with legacy systems. This hard drive is built to handle heavy workloads and is engineered for reliability, making it an ideal choice for mission-critical applications.Interface and Connectivity
The Seagate 1GR221-251 10K.8 1.8TB SAS-12GBPS 128MB 512E Hard Drive features a SAS (Serial Attached SCSI) interface with a 12 Gbps data transfer rate. SAS is a high-speed, reliable, and scalable data storage interface that is designed for enterprise-level server and storage systems. It uses a point-to-point connection, which allows for faster data transfer and improved error detection and correction.
This hard drive also supports dual-port connectivity, which allows for redundancy and improved data availability. With dual-port connectivity, the hard drive can be connected to two separate host bus adapters (HBAs), providing a fail-safe mechanism in case one port fails. This feature helps to ensure that the data stored on the hard drive is always available, even in the event of a failure.
Additionally, it is backward compatible with SAS 6 Gbps and SAS 3 Gbps interfaces, making it compatible with legacy systems.
High-speed data transfer
The Seagate 1GR221-251 10K.8 1.8TB SAS-12GBPS 128MB 512E Hard Drive features a SAS interface with a 12 Gbps data transfer rate, providing high-speed data transfer capabilities. With a 12 Gbps data transfer rate, this hard drive can transfer large amounts of data quickly and efficiently, making it well-suited for use in high-performance enterprise-level server and storage systems.
This high data transfer rate is achieved through the use of a wider data bus and more advanced signal processing techniques. The 12 Gbps SAS interface can transfer data at a rate of up to 1.2 GB/s, which is faster than the previous 6 Gbps SAS interface that could transfer data at a rate of up to 600 MB/s. This makes it suitable for high-performance applications such as big data analytics, online transaction processing, and video streaming.
The large 128MB cache and fast 7200 RPM spindle speed also contribute to improved read and write speeds, making it ideal for heavy workloads and mission-critical applications.
