SAS Interface and Data Transfer
SAS (Serial Attached SCSI) interface and data transfer are important considerations for data center hard drives, as they determine the speed and reliability of data transfer between the drive and the server or storage array.
The HPE 793701-B21 SAS drive offers high-performance SAS interface and data transfer for data center applications:
- SAS Interface: The drive connects to the server or storage array using SAS interface, which supports faster data transfer rates and more reliable connections compared to other interfaces such as SATA. SAS is a widely used interface in data center environments.
- Data Transfer Rate: The drive supports data transfer rates of up to 12 Gb/s, which is faster than SATA interfaces. This allows for faster data access and transfer speeds, which is beneficial for data center applications such as backup, archiving, and storage for big data analytics.
- Advanced Format 4Kn: The drive is designed to use 4Kn (4 kilobyte-per-sector) advanced format which is designed to increase storage density and reduce the amount of disk space consumed by file system overhead.
- Multi-path Support: The drive supports multi-path I/O, which allows for multiple connections to the drive at the same time. This can help to increase the availability of data and improve performance in large and complex data center environments.
Form Factor and Design
Form factor and design are important considerations for data center hard drives, as they determine the physical size and layout of the drive, and how easily it can be integrated into existing data center infrastructure.
The HPE 793701-B21 SAS drive features a Large Form Factor (LFF) design, which is well-suited for data center environments:
- LFF Design: The drive has a LFF design, which is larger than the small form factor (SFF) drives. LFF drives are typically used in data center environments, as they offer higher storage capacity and better performance than SFF drives.
- Physical Size: The drive has a standard 3.5-inch form factor, which is the industry standard for data center hard drives. This makes it compatible with a wide range of server and storage arrays that accept 3.5-inch drives.
- Hot-Swappable: The drive is hot-swappable, which means it can be replaced or upgraded without having to shut down the server or storage array. This can help to minimize downtime and ensure that data is always available.
- Ease of installation: The drive is designed for easy installation and integration into existing data center environments. The drive can be easily plugged into the server or storage array and configured with minimal setup required.
Reliability and Durability
Reliability and durability are crucial factors for data center hard drives, as they determine the longevity and dependability of the drive.
The HPE 793701-B21 SAS drive is designed for high reliability and durability:
- MTBF: The drive has a Mean Time Between Failure (MTBF) of 2.5 million hours, which is a measure of how long the drive can operate without failing. A higher MTBF indicates a more reliable drive.
- Error recovery: The drive has advanced error recovery features that help to prevent data loss and minimize downtime in the event of a drive failure.
- Rotational vibration tolerance: The drive is designed to tolerate rotational vibration, which can occur when multiple hard drives are operating in close proximity. This helps to reduce the risk of drive failure and increase the reliability of the drive.
- Endurance: The drive is rated for high endurance, which is a measure of how many writes and reads a drive can handle over time. High endurance is important for data center applications that involve frequent writes and reads, such as backups, archiving, and storage for big data analytics.
- Warranty: The drive is backed by HPE's standard limited warranty, which provides coverage for defects in materials and workmanship.

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.
