The Western Digital Ultrastar DC HC520 12TB 7.2K RPM SAS-12GBPS Enterprise Hard Drive with part number 0F29535 is a high-performance hard drive that provides fast data transfer speeds and large storage capacity.
With a rotation speed of 7200 RPM, this hard drive offers faster data access compared to slower 5400 RPM drives, and also provides improved performance for random I/O workloads. The SAS 12 Gbps interface provides faster data transfer rates compared to SAS 6 Gbps or SAS 3 Gbps, and support for 12 Gbps speeds can help to maximize the performance of your server or storage system.
The 12TB capacity of this hard drive provides ample storage space for large data sets and can help to reduce the need for additional storage devices, which can help to lower overall storage costs.
This drive is designed for use in enterprise-level servers and storage systems that require high-performance storage solutions for data-intensive workloads such as virtualization, big data analytics, and data warehousing.
The Western Digital Ultrastar DC HC520 is also known for its exceptional reliability, it features advanced technologies such as rotational vibration sensors and advanced error correction algorithms that help to ensure data integrity and protect against data loss due to hardware failures.
ReliabilityThe Western Digital Ultrastar DC HC520 12TB 7.2K RPM SAS-12GBPS Enterprise Hard Drive with part number 0F29535 is known for its exceptional reliability.
Western Digital has a reputation for producing high-quality hard drives that are designed to withstand the demands of enterprise-level environments. This hard drive features advanced technologies such as rotational vibration sensors and advanced error correction algorithms that help to ensure data integrity and protect against data loss due to hardware failures.
Additionally, this hard drive is built with a high-quality, durable design that can withstand the rigors of continuous use in data centers and other demanding environments. The drive also have a MTBF (Mean Time Between Failure) of 2.5 Million hours which is a measure of a device's expected reliability, the higher the MTBF the more reliable the device is expected to be.
Western Digital also provides a five-year limited warranty on this hard drive, which provides an additional level of protection for the drive and offers peace of mind knowing that you are covered in case of any hardware failures.
It's also worth mentioning that this hard drive is tested for compatibility and reliability with the servers and storage systems it is intended to be used in, which helps to ensure seamless integration and optimal performance.
Serial-Attached SCSI (SAS)Serial-Attached SCSI (SAS) is a high-speed data storage interface that is used to connect servers and storage systems to storage devices such as hard disk drives (HDDs) and solid-state drives (SSDs). SAS is a point-to-point interface, which means that each device is connected directly to the host, rather than sharing a common bus.
SAS supports data transfer rates of up to 12 Gbps, which is faster than its predecessor, SAS 3 Gbps and SAS 6 Gbps. It also supports full-duplex data transfer, allowing data to be sent and received simultaneously.
SAS devices can be connected in a variety of topologies, including direct-attached storage (DAS) and storage area networks (SANs). SAS also supports the use of multiple paths to a single storage device, which can help to improve data availability and provide automatic failover in case of a failure.
SAS is also backward-compatible with the older parallel SCSI interface and also compatible with SATA. This means that SAS devices can be connected to older SCSI or SATA devices and vice versa, SAS devices can be used in conjunction with SAS or SATA drives in a single server or storage system.
SAS is considered as a robust and reliable interface and widely used in enterprise-level servers and storage systems, as well as in data centers and other demanding environments.

Data loss or damages to any other equipment we do not cover by our offered warranty.
What is the Manufacturer/Brand Warranty?
In general, a manufacturer's warranty service/support is a written guarantee to the buyer of a product. Its terms assure the replacement or repair of the product, if necessary, within a specified period after the purchase (2-5 years depending on the brand/manufacturer). It is typically included in the price of the product. Products are brand new and sealed and the original manufacturer box is complete with the Manufacturer's genuine warranty. For most of the brand new/retail products that come with the manual and box, exceptions may apply (i.e., Cisco, Juniper Networks).
For the server parts (i.e., Dell, HPE) to get Full coverage of the warranty server must have a full 3- 5 years warranty. However, ALLHDD.COM will cover the warranty duration if any Manufacturer doesn't support the advertised warranty and there is no refund for those.
