The performance of the HPE 791034-B21 hard drive will depend on a number of factors, including the device it is installed in, the workload it is subjected to, and the type of data being accessed. In general, hard drives with a higher spindle speed and larger buffer size may offer improved performance, but other factors such as the interface and the drive's firmware can also affect its performance.
In terms of specific performance metrics, the 791034-B21 has a sustained transfer rate of up to 210 MB/s (megabytes per second) and an average seek time of 3.8 milliseconds. These numbers are just rough estimates and may vary depending on the specific use case.
It is worth noting that hard drives are generally slower than solid state drives (SSDs) and may not be the best choice for applications that require high input/output operations per second (IOPS). SSDs are generally faster than hard drives and can offer improved performance in certain workloads, but they tend to be more expensive on a per-gigabyte basis.
The 791034-B21 is a 1.8 TB hard drive from HPE (Hewlett Packard Enterprise) with a spindle speed of 10000 RPM. It uses the SAS (Serial Attached SCSI) interface with a data transfer rate of 12 Gbps (gigabits per second) and comes with a tray for easy installation in a server or storage system. It has a 2.5-inch form factor and is a hot-swappable drive, meaning it can be removed and replaced while the system is running.
In terms of compatibility, the hard drive should be compatible with any device that supports the SAS interface and has a free 2.5-inch drive bay. You should check the manufacturer's documentation for your device to confirm that it is compatible with 2.5-inch hard drives and has a free drive bay available. You should also check that the hard drive's power and data cables are compatible with your device.

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.
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.
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.
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.
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.
