Detail Information of 20TB HDD
The Seagate ST20000NM004D is a hard drive model with a storage capacity of 20 terabytes (TB). It operates at a rotation speed of 7200 revolutions per minute (RPM) and uses the Serial Attached SCSI (SAS) interface with a 12 Gbps data transfer rate.
It is designed for use in enterprise environments, where high-capacity storage and reliable performance are required. Enterprise hard drives typically have features such as enhanced error correction and power-loss protection, to help ensure data integrity and availability in demanding usage scenarios.
Additionally, this drive is optimized for enterprise bulk data storage, cloud and hyper-scale, data warehousing and mining, and video surveillance storage.
This Drive uses 7200 RPM which is typical for enterprise hard drives, but as a trade-off, it consumes more power as well as generates more heat compared to a 5400 RPM hard drive.
Performance and Reliability
The Seagate ST20000NM004D is designed for enterprise environments, where high performance and reliability are crucial.
In terms of performance, the 7200 RPM rotation speed allows for faster data access times compared to slower-spinning hard drives, which can help improve overall system responsiveness. The 12 Gbps SAS interface enables high-speed data transfer rates, allowing for faster data transfer and backup.
Reliability is also an important aspect of enterprise hard drives. This product is designed to be highly reliable, with features such as enhanced error correction and power-loss protection to help ensure data integrity and availability. The drive also has a rated workload rate limit of 550TB per year , which is a high endurance level and suitable for heavy use.
In terms of compatibility, This product uses the SAS interface, which is typically used in enterprise storage systems. SAS is a point-to-point protocol, meaning that each drive has its own dedicated connection to the host, allowing for faster data transfer rates and improved scalability. The drive is also backward-compatible with SAS 6 Gbps and 3 Gbps systems, so it can be used in older systems as well.
However it is important to note that SAS interface is different than SATA, and SAS drive usually needs SAS host or SAS-to-SATA Adapter to connect to a standard SATA controller, which could make it less compatible with non-enterprise or older systems that only supports SATA interface.
The Seagate ST20000NM003D is an enterprise-level hard drive that comes with a variety of specifications that make it well-suited for high-performance storage applications. The key specifications of the drive include:
- Capacity: 20TB
- Rotational Speed: 7.2K RPM
- Interface: SAS 12 Gbps
- Cache: 256MB
- Form Factor: 3.5-inch
- Data transfer rate: 12 Gbps

- Uncorrectable Bit Error Rate (UBER): <1 in 10^17
- Dimensions: 101.6mm x 147mm x 26.1mm
- Weight: 740g
With 20TB of storage capacity, the drive provides ample space for storing large amounts of data. The 7.2K RPM speed enables fast data access and retrieval, and the SAS 12 Gbps interface and 12 Gbps data transfer rate support fast data transfer between the drive and the host system. The 256MB cache works as a buffer between the drive and the host system, allowing for faster data access and retrieval. With an MTBF of 2.5 million hours and UBER of <1 in 10^17, the drive is built to last and to provide high reliability.

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 utmost attention in the market as a result of its 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 drives 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 a cost-effective choice for users.
The 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 in 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, allowing 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 rigors of heavy workloads and enterprise use. They also safeguard data integrity, thanks to their ability to comprehensively verify data and correct errors.
