Description
High-performance
The Dell J73RH 18TB 7.2K RPM SAS 12GBPS Near Line hard drive is considered high-performance because of several factors.
Firstly, its storage capacity of 18TB is large, which makes it well-suited for use in data centers and other high-storage applications.
Secondly, the drive has a rotation speed of 7.2K RPM, which is faster than typical “nearline” storage drives. This means that the drive can access data more quickly, which is important for applications that require fast data access.
Thirdly, it uses the SAS 12GBPS interface which allows for faster data transfer rates. SAS (Serial Attached SCSI) is a high-speed data transfer interface that is commonly used in data centers and enterprise storage systems. The 12GBPS SAS interface allows for faster data transfer rates than the previous 6GBPS SAS interface, which can improve the overall performance of the storage system.
Finally, the hard drive comes with a tray, which makes it easy to install and handle. This can reduce the time and effort required to install and maintain the drive, which can improve the overall performance of the storage system.
More Information
The Dell J73RH 18TB 7.2K RPM SAS 12GBPS Near Line hard drive is a high-performance, high-capacity hard drive designed for use in data centers and other high-storage applications. Here are some additional details about this drive:
- Capacity: 18TB. This is a large amount of storage capacity, which makes the drive well-suited for use in data centers and other applications that require a lot of storage space.
- Rotation Speed: 7.2K RPM. This is the speed at which the drive’s platters rotate. 7.2K RPM is faster than the typical 5.4K or 5.9K RPM of nearline storage drives, which can improve the drive’s performance.
- Interface: SAS 12GBPS. SAS (Serial Attached SCSI) is a high-speed data transfer interface that is commonly used in data centers and enterprise storage systems. The 12GBPS SAS interface allows for faster data transfer rates than the previous 6GBPS SAS interface, which can improve the overall performance of the storage system.
- Form factor: 3.5 inches. This is the standard size for most desktop and enterprise hard drives.
-Cache: 512MB, it’s a buffer memory that helps to improve the performance of the drive by storing frequently accessed data.
- Error Correction Code (ECC): Built-in ECC that can detect and correct errors in the data stored on the drive, which can help to improve the drive’s reliability and data integrity.
- Warranty: Dell offers a 5 years warranty on this drive, which gives peace of mind for the customer.
- Compatibility: The drive is compatible with a wide range of servers and storage systems that support the SAS 12GBPS interface.
Interfaces
The Dell J73RH 18TB 7.2K RPM SAS 12GBPS Near Line hard drive uses the SAS (Serial Attached SCSI) interface. SAS is a high-speed data transfer interface that is commonly used in data centers and enterprise storage systems. The SAS interface allows the drive to connect to a SAS controller, which in turn connects to the host system.
The SAS 12GBPS interface allows for faster data transfer rates than the previous 6GBPS SAS interface. The 12Gbps SAS doubles the data transfer rate of 6Gbps SAS and it’s backward compatible with 6Gbps SAS, allowing the use of existing SAS infrastructure. This improved data transfer rate can help to improve the overall performance of the storage system.
SAS is a point-to-point interface, which means that each drive has its own dedicated connection to the SAS controller. This can help to improve the performance and scalability of the storage system, as compared to traditional parallel SCSI interfaces.
The drive also supports the Serial Attached SCSI (SAS) 2.0 protocol, which is a standard for data transfer between servers and storage systems. SAS 2.0 provides faster data transfer rates and improved data integrity compared to SAS 1.1, making it well-suited for use in high-performance storage systems.
