Reliability
The reliability of the Western Digital HUH721212AL4201 hard drive can be determined by looking at its mean time between failures (MTBF) rating. The MTBF rating is an estimate of how long the drive can operate before it fails. A higher MTBF rating indicates a more reliable drive. This particular hard drive has a MTBF rating of 2 million hours, which is considered to be very high and indicates a high level of reliability.
Additionally, this hard drive also has a number of features that contribute to its reliability. The SAS interface provides faster data transfer speeds and improved error detection and correction. The large buffer size of 256MB allows for improved performance and data protection. The drive also has vibration protection and is built to operate under high temperatures.
It's worth noting that hard drives are mechanical devices and are subject to wear and tear over time. Even with high MTBF rating, an hard drive can fail at any time, thus it's recommended to use them in RAID configuration or with a backup system in place to minimize the risk of data loss.
Information
The Western Digital HUH721212AL4201 is a 12 terabyte (TB) hard drive with a rotation speed of 7200 revolutions per minute (RPM). It is designed for use in enterprise environments and it's a high-performance hard drive.
It has a SAS (Serial Attached SCSI) interface, which is a faster and more reliable interface compared to SATA. SAS supports data transfer rates of up to 12 gigabits per second (GB/s) and also provides improved error detection and correction. This makes it suitable for use in high-availability systems and data centers.
The drive has a large buffer size of 256 megabytes (MB), which is used to temporarily store data before it is written to the drive's platters. This improves the drive's performance by allowing it to handle more data at once and reduces the chances of data loss.
The hard drive also has vibration protection and is built to operate under high temperatures. This makes it suitable for use in environments where there may be vibration or high temperatures, such as in data centers or other enterprise environments.
It's a 3.5 inches form factor, which is the standard size for most internal hard drives. It's designed to be used in servers, storage arrays and other types of enterprise-level storage systems.
Interfaces
The Western Digital HUH721212AL4201 hard drive has a SAS (Serial Attached SCSI) interface. SAS is a high-speed and high-performance interface used for connecting storage devices to a computer or server. It is commonly used in enterprise-level environments, such as data centers, and is considered to be more reliable and faster than SATA (Serial ATA) interfaces.
SAS supports data transfer rates of up to 12 gigabits per second (GB/s), which is significantly faster than SATA's maximum data transfer rate of 6 GB/s. SAS also provides improved error detection and correction, which helps to ensure data integrity and reduces the chances of data loss.
SAS also supports multiplexing, which allows multiple devices to share a single SAS port. This allows for more efficient use of server resources and can help to reduce costs.
Additionally, SAS interfaces also support hot-swapping, which allows you to replace a failed drive without shutting down the system, allowing for minimal downtime.

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.
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 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.
Utmost Flexibility
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.
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 rigours of heavy workloads and enterprise use. They also safeguard data integrity, thanks to their ability to comprehensively verify data and correct errors.Warranty
