More Information
The Dell 18TB 7.2K RPM SAS 12GBPS 512MB Buffer NL Hard Drive is a high-capacity, near-line hard drive designed for enterprise storage systems.
This Item has a storage capacity of 18 terabytes and a rotation speed of 7200 RPM. This provides faster data access times than slower-spinning drives, which can help improve the overall performance of the storage system.
The drive uses the SAS-12GBPS interface, which is a 12 Gbps SAS interface that supports the latest generation of SAS-based storage solutions. This interface provides faster data transfer speeds than SAS-6GBPS and SAS-3GBPS interfaces, allowing for faster data access and better performance when working with large data sets or when multiple users are accessing the data simultaneously.
The HDD also has a 512MB buffer which helps to improve the overall performance of the drive by allowing for faster data access.
This storage, which means it's suitable for less frequently accessed data, such as archival data, backups, and large media files. It's not as fast as "performance" storage but still faster than "capacity" storage.
Overall, the Dell 18TB 7.2K RPM SAS 12GBPS 512MB Buffer NL Hard Drive is a high-capacity, high-performance storage solution for enterprise-grade systems and applications that require large amounts of storage and fast data access for less frequently accessed data.
Drive Compatibility
The Dell 18TB SAS 12 Gbps hard drive with a 512MB buffer and "NL" (Nearline) designation is compatible with servers and storage systems that support SAS 12 Gbps interfaces and have a SAS backplane or controller. It is recommended that you check with your server or storage system vendor for specific compatibility information, as well as the firmware version of your SAS controller. It is also important to ensure that the drive is supported by your RAID controller as well as the RAID level you are using. The "NL" designation indicates that this drive is designed for nearline storage which typically refers to data archiving or backup storage, and may not be suitable for primary storage or high-performance workloads. It is also important to note that this drive is designed for use in enterprise and data center environments, and may not be compatible with consumer-grade computer systems. It is recommended to check the system documentation and ensure that the drive is supported by your RAID controller as well as the RAID level you are using.
Backup & Restore Facilities
To perform a backup and restore on a Dell 18TB SAS 12GBPS hard drive, you can use a variety of backup software options, such as Dell EMC Data Protection Suite, Dell EMC NetVault Backup, or third-party software like Veeam or Acronis. The specific steps will depend on the software you choose, but generally, the process involves creating a backup of the data on the hard drive, and then restoring the data to the hard drive from the backup.
Here's a general overview of the process:
- Install and configure the backup software on your system.
- Connect the Dell 18TB SAS 12GBPS hard drive to your system.
- Create a new backup job in the software and select the hard drive as the source of the backup.
- Choose the backup type (full, incremental, differential) and schedule the backup to run at a convenient time.
- Verify that the backup has completed successfully.
- To restore data, choose the restore option in the software, select the backup you want to restore from, and specify the location where you want to restore the data.
Please note that it is always a good idea to verify the integrity of the backup and also to have multiple copies of the backup stored in different locations to protect against data loss.

The Serial Attached SCSI (SAS) hard drives have become increasingly popular for their increasing use in high-end workstations and servers. These drives are employed in consumer desktops and modern servers for their speed and reliability. Enterprises have made the SAS hard drives their de-facto standard. Now, the 12Gbps speed throws the usefulness of these drives up a notch.
Most professional hosting providers now use SAS 12Gbps hard drives for data production. These drives have proven useful in high input/output operations and critical website functions. Users trust these drives because there is no risk of data loss, corruption, or downtime.
Faster Throughput
SAS 12Gbps drives read, write, and process data within split seconds. The latest 12Gbps disks use the latest RAID hardware technology to offer faster data transfer and recovery rates. They are perfect for sequential data, high workloads, and random IOPS alike.
This function allows them to be best suited for servers that have 100 percent duty cycles. They do not only work with desktops and PCs, but they can read/write data 24/7.
Higher Performance
SAS 12Gbps HDDs have received utmost attention in the market as a result of its high performance. These performance benefits allow it to be useful for a wide variety of applications. For instance, a SAS 12Gbps connection can support up to four wide lanes per connection.
Connecting JBOD with these SAS drives can support up to 1200MB/s. These high-performance drives do not only help handle large workloads; they also offer cost-effective expansion to an already robust system.
Also, each 12Gbps high-performance SAS drives can offer users a rotational speed of up to 15000 rpm.
They provide a great bandwidth enough to perform efficiently. The robust performance of SAS 12Gbps drives clearly a worthy investment for improved performance of servers and desktops. They provide very large amounts of storage options and a cost-effective choice for users.
Utmost Flexibility
The flexibility is one of the best benefits of SAS 12Gbps drives. These drives have configured flexibility, which allows them to work perfectly with several devices without modification or changes. Many of them feature a Universal Serial controller for seamless system support.
SAS 12Gbps hard drives can also be partitioned in a storage pool and assigned to servers for work-intensive applications. They are a perfect fit for server systems, including reservation systems, medical imaging, and more!
Only this range of SAS hard drives can provide users with the best worlds of flexibility. This way, allowing them to support use with other drives.
Increased Availability
12Gbps SAS-based storage systems have the benefit of dual-port capability. This allows them to provide a redundant path to the drives in case of controller failover. These drives also operate on separate point-to-point connections. That way, it is rare for drive connection loss to affect them.
SAS 12Gbps HDDs are built to handle the rigors of heavy workloads and enterprise use. They also safeguard data integrity, thanks to their ability to comprehensively verify data and correct errors.Warranty
