Power consumption refers to the amount of electrical power required by a device to operate. Hard drives, like the HPE 857644-H21, consume power to spin the disk platters, move the read/write heads, and power the electronic components that control the drive.
The power consumption of a hard drive can be measured in watts (W) and is affected by factors such as the drive's capacity, rotational speed, and other features. The power consumption of HPE 857644-H21 hard drive is not specified by the manufacturer, however, in general, hard drive power consumption can be broken down into two categories: idle power and active power.
Idle power refers to the amount of power consumed by the drive when it is not actively reading or writing data. This power consumption is generally low and is used to keep the drive spinning and the electronic components powered on.
Active power refers to the amount of power consumed by the drive when it is actively reading or writing data. This power consumption is generally higher and can vary based on the specific activity the drive is performing.
It is important to consider the power consumption of a hard drive, especially when deploying large numbers of drives in a data center or other high-density environment.
Environmental specifications refer to the operating conditions under which a device, such as the HPE 857644-H21 hard drive, can function correctly and reliably. These specifications typically include parameters such as temperature, humidity, and vibration.
The HPE 857644-H21 hard drive has the following environmental specifications:
- Operating temperature range: 5°C to 55°C (41°F to 131°F)
- Non-operating temperature range: -40°C to 70°C (-40°F to 158°F)
- Operating humidity range: 8% to 90% non-condensing
- Non-operating humidity range: 5% to 95% non-condensing
- Operating vibration: 0.25 Grms (5 to 500 Hz)
- Non-operating vibration: 3.0 Grms (5 to 500 Hz)
It is important to note that the hard drive should be operated within the specified temperature and humidity range to ensure proper functioning and to prevent damage to the drive. In addition, the vibration specification is important to ensure the drive can withstand the vibration that may be caused by the equipment it is installed in.
It's also important to consider the altitude and airflow around the drive, as well as the storage conditions, as the HPE 857644-H21 hard drive is intended for use in data centers and other enterprise-class storage environments.
Performance comparison refers to the process of evaluating and comparing the performance characteristics of different devices, such as hard drives. In the case of the HPE 857644-H21 hard drive, performance comparison would involve comparing its capabilities and specifications to those of other hard drives on the market.
Some of the key performance metrics that can be used to compare hard drives include:
- Capacity: The amount of storage space available on the drive.
- Rotational speed: The speed at which the disk platters spin, measured in revolutions per minute (RPM).
- Data transfer rate: The speed at which data can be read from or written to the drive, measured in megabytes per second (MB/s) or gigabytes per second (GB/s).
- Latency: The time it takes for the drive to access a specific piece of data, measured in milliseconds (ms).
- Access time: The average time it takes for the drive to access a random piece of data, measured in milliseconds (ms).
When comparing the HPE 857644-H21 hard drive to other drives, it is important to note that it has a capacity of 10TB, a rotational speed of 7200 RPM, and a data transfer rate of 12GB/s.
It is also important to consider other factors such as compatibility with the host system, power consumption, and environmental specifications, as well as the intended usage scenario, warranty and support options.

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 the utmost attention in the market as a result of their 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 drive 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 are a cost-effective choice for users.
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 into 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, allows 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 rigours of heavy workloads and enterprise use. They also safeguard data integrity, thanks to their ability to comprehensively verify data and correct errors.
