SAS interface and data transfer rates
The SAS (Serial Attached SCSI) interface is a high-speed data storage interface that uses a serial protocol to transfer data between computer systems and storage devices, such as hard drives and solid-state drives. The interface allows for faster data transfer rates and more reliable connections than older parallel SCSI interfaces.
Data transfer rate is the amount of data that can be moved from one place to another in a given amount of time. In the case of hard drives, it is measured in bytes per second. The data transfer rate for the 857646-B21 HPE 10TB 7.2K RPM SAS 12GBPS Midline LFF Hard Drive is 12 Gbps, which means that it can transfer data at a maximum rate of 12 gigabits per second. This is a high data transfer rate, which makes it suitable for use in high-performance storage systems and data centers.
Power consumption and environmental
Power consumption refers to the amount of electrical power required for a device or system to operate. Environmental specifications refer to the conditions under which a device or system is designed to operate, such as temperature and humidity ranges.
The 857646-B21 HPE 10TB 7.2K RPM SAS 12GBPS Midline LFF Hard Drive has a power consumption rating of 9.5 watts when active and 5.8 watts when idle. This is considered to be a relatively low power consumption for a hard drive of this capacity and performance.
The environmental specifications for this hard drive include operating temperatures between 41°F and 131°F (5°C and 55°C), and non-operating temperatures between -40°F and 158°F (-40°C and 70°C). It also has a relative humidity range of 8% to 90% (non-condensing). This means that the hard drive is designed to operate within these temperature and humidity ranges, and may not perform correctly or may be damaged if operated outside of these limits.
Compatibility with HPE servers and storage arrays
Compatibility refers to the ability of a device or system to work with other devices or systems. In the case of the 857646-B21 HPE 10TB 7.2K RPM SAS 12GBPS Midline LFF Hard Drive, compatibility refers to its ability to work with HPE servers and storage arrays.
This hard drive is specifically designed to be compatible with HPE servers and storage arrays that use a SAS interface and support the LFF form factor. It should be compatible with a wide range of HPE ProLiant servers and storage arrays, including those that support 12 Gbps SAS technology. The compatibility list can be found in the HPE website, it is important to check the compatibility before purchasing this hard drive.
It is recommended to check the documentation of the specific HPE server or storage array that the hard drive will be used with to ensure that it supports the 857646-B21 model and that it meets the necessary technical specifications.

About Refurbished Products
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.
