Description
More Information
The Dell 2DWFW 18TB 7.2K RPM ISE Near Line SAS-12GBPS 512MB 512e 3.5-inch hard drive is a high-capacity storage solution for enterprise-level storage systems. The drive has a capacity of 18 terabytes, which is large enough to store a significant amount of data. The drive has a rotational speed of 7.2K RPM, which is a moderate speed that provides a balance of performance and energy efficiency.
The drive uses the SAS (Serial Attached SCSI) interface, which is a high-performance data transfer standard that is commonly used in enterprise storage systems. The drive also supports a data transfer rate of 12 Gbps, which is a fast data transfer rate that enables the drive to quickly transfer large amounts of data.
The Storage is a “nearline” drive, which means it’s designed for use in data storage systems that require high storage capacity, but don’t require the same level of performance as “enterprise-class” drives. Nearline drives are typically used for storing archival data, backups, and other non-critical data.
The drive uses ISE (Integrated Sector Error) technology which reduces the risk of data loss from an unreadable sector. Additionally, it has a buffer size of 512MB and it uses the 512E sector format which is the industry standard for larger capacity drives. This format increases the compatibility and allows the drive to work with systems that are not capable of handling the new Advanced Format 4K sector standard.
This is also a 3.5-inch form factor (LFF) drive, which is the standard size for enterprise-level storage systems. This form factor allows the drive to fit in a wide range of storage systems and enclosures.
Drive Reliability
The reliability of a hard drive can be affected by various factors such as the quality of the components used, the manufacturing process, and the workload the drive is subjected to. In general, enterprise-grade hard drives like the Dell 18TB SAS-12GBPS 512MB 512e 3.5-inch HDD are designed to be more reliable than consumer-grade hard drives.
Dell’s enterprise-class hard drives are built to meet the demands of high-availability environments and undergo rigorous testing to ensure they meet high standards for performance, reliability, and data integrity.
The 512e feature and 512MB buffer, as well as SAS interface, are designed for enterprise-class storage and provide increased reliability and performance.
It’s important to note that the actual reliability of a hard drive can also be influenced by how it’s used and the environment in which it’s deployed, such as temperature, humidity, and vibration. Properly maintaining and monitoring the drive and the system it’s used in can help ensure optimal performance and reliability.
Backup & Restore Facilities
Backing up and restoring data on a Dell 18TB SAS-12GBPS HDD would involve using a backup software program to copy and save the data from the drive to another storage location, such as a separate hard drive or a cloud-based storage service. This process can be done on a regular schedule, such as daily or weekly, to ensure that the data is always protected in the event of a hard drive failure or other data loss event.
When restoring data, the backup software would be used to copy the saved data back onto the original hard drive, or onto a new hard drive if the original has failed. This process can take some time, depending on the amount of data being restored and the speed of the backup and restore process.
It’s important to note that a backup of the data is essential to ensure the data integrity and availability in case of any data loss event. It’s also important to test the backups regularly and to have a disaster recovery plan in place.
Dell also provides a software tool named Dell Data Protection | Rapid Recovery, which is a data backup and recovery software solution that allows you to protect, recover and restore your data, systems, and applications. It supports multiple platforms and it’s scalable to your needs.
