Dell 20 TB Hard Drive - 3.5" Internal - SAS (12Gb/s SAS)

Elevate your data infrastructure with the Dell 20 TB Hard Drive, a purpose-built, enterprise-grade 3.5-inch internal hard drive designed for servers and storage arrays. This high-capacity SAS drive combines enormous storage density with dependable performance to support backup, archival, virtualization, media libraries, and data-intensive workloads. Built to meet the demands of data centers and workloads that never sleep, it delivers steady throughput, robust reliability, and seamless integration with Dell PowerEdge servers and compatible backplanes. Whether you’re expanding an on-premises storage pool, scaling a backup appliance, or extending a data lake, this 20 terabyte HDD is engineered to keep critical data readily accessible while maximizing your cost per gigabyte. The drive’s 7,200 RPM rotational speed and SAS interface work together to provide faster sequential transfers and more consistent IOPS under sustained workloads, helping you reduce bottlenecks in RAID arrays and storage subsystems. In today’s data-centric environment, enterprise storage demands both capacity and resilience—and this Dell drive is designed to deliver both with efficiency and longevity. The result is a scalable, dependable solution for long-term data retention, business continuity, and rapid recovery times in the event of data loss or disruption.

• Massive capacity for data growth: At 20 TB, this drive is ideal for large-scale backups, archival storage, media libraries, and data-intensive workloads that require long-term retention without sacrificing performance or reliability. It enables you to consolidate multiple workloads into a single, cost-efficient storage pool, reducing clutter and simplifying management while preserving fast access to historical data.
• Enterprise-class performance: The 7,200 RPM spindle speed delivers strong sequential throughput, enabling faster file transfers and quicker large-block reads and writes. This translates to shorter backup windows, faster data restores, and more responsive virtualized environments where storage latency can impact application performance.
• SAS interface for higher throughput: The 12 Gb/s SAS interface provides higher sustained data transfer rates and improved I/O efficiency in RAID arrays, storage enclosures, and backplanes. SAS also offers advanced error detection and robust link reliability, contributing to sustained performance under heavy workloads and mixed I/O patterns.
• 3.5-inch enterprise form factor: Built for rack-mount servers and storage arrays, this drive fits standard 3.5-inch bays and backplanes used in data centers worldwide. The enterprise design is optimized for continuous operation, with mechanisms that support extended workloads, higher duty cycles, and predictable performance during 24/7 operation.
• Reliability for data-critical environments: Engineered for durability in demanding IT environments, this drive is designed to handle the rigors of enterprise storage, including heavy read/write cycles, vibration tolerance in multi-drive deployments, and long-term endurance needed for business continuity and disaster recovery plans.

Frequently asked questions

• Q: What systems is this Dell 20 TB SAS drive compatible with? A: This drive is designed for enterprise servers and storage backplanes that support 3.5-inch SAS drives and 12 Gb/s SAS interfaces. Verify compatibility with your server model, RAID controller, and backplane before deployment.
• Q: Can I use this drive in a consumer desktop PC? A: While it may be physically possible in certain configurations with the right backplane or expansion controller, this drive is intended for enterprise environments. Many consumer systems do not support 12 Gb/s SAS or the required backplane connections, and this can lead to limited functionality or compatibility issues.
• Q: Is this drive suitable for high-write workloads? A: Yes. Enterprise-grade 3.5-inch SAS drives are designed for heavy read/write operations, long duty cycles, and high-availability deployments, making them well-suited for backups, databases, virtualization hosts, and data-intensive workloads.
• Q: Does this drive support hot-swapping? A: Compatibility with hot-swapping depends on your server chassis, backplane, and controller. Many Dell PowerEdge servers and enterprise backplanes support hot-swapping for 3.5-inch SAS drives when properly configured, but always confirm with your hardware documentation.
• Q: What warranty or support covers this drive? A: Warranty terms vary by region and reseller. When purchasing through authorized Dell channels or approved distributors, you typically receive enterprise-grade warranty coverage appropriate for data-center deployments.
