- Form Factor: 3.5" – standard size that fits seamlessly into most server chassis and rack‑mount enclosures.
- Interface: SATA III (Serial ATA III) – supports a maximum data transfer rate of up to 6 Gb/s, ensuring fast read/write operations.
- Rotation Speed: 7 200 RPM – balances performance with energy efficiency, providing quick access times for frequently used data.
- Hot‑Swap / Hot‑Plug: Yes – allows the drive to be replaced or added while the system remains powered on, minimizing downtime.
- Operating Voltage: 5 V / 12 V – compatible with a wide range of Dell server power supplies.
- Weight: 25 g – lightweight design reduces overall chassis load and improves airflow.
Compatibility Overview
The 400‑AEFB is engineered to work flawlessly with a broad spectrum of Dell PowerEdge models, ensuring that administrators can upgrade or expand storage without compatibility concerns. The supported systems include:
- PowerEdge R230, R330, T430, T330
- PowerEdge R530, R730, R730XD, R430
These servers span entry‑level to high‑end configurations, making the 400‑AEFB a versatile choice for both small businesses and large enterprises.
Performance Highlights
- Sequential Read/Write: The SATA III interface coupled with a 7 200 RPM spindle delivers consistent throughput, essential for database transactions and virtualization workloads.
- Random I/O: With a high rotational speed, the drive achieves low latency for random access patterns, improving overall system responsiveness.
- Reliability: Dell’s rigorous quality control ensures that each unit meets strict durability standards, reducing the risk of data loss in critical environments.
Installation and Hot‑Swap Procedure
- Power Off (if not using hot‑swap): For non‑hot‑swap installations, shut down the server and disconnect power to avoid electrical hazards.
- Locate Drive Bay: Identify an available 3.5" drive bay within the chassis. Ensure that the bay supports hot‑swap if you plan to replace drives while the system is running.
- Insert Drive: Align the SATA connectors and secure the drive with the provided screws or latch mechanism.
- Connect Power: Attach the power connector from the server’s backplane to the drive. The dual voltage capability (5 V/12 V) allows flexibility in power routing.
- Power On / Hot‑Swap: If using hot‑swap, simply power on the system; the drive will be recognized automatically by the operating system and firmware.
Use Cases
- Virtualization Platforms: Store virtual machine images or snapshots with high I/O demands.
- Database Servers: Provide reliable storage for relational databases, NoSQL stores, and data warehouses.
- Media & Content Creation: Archive large video files, graphics assets, or backup media libraries.
- High‑Availability Clusters: Deploy in redundant configurations to ensure continuous service during maintenance or failure events.
Why Choose the Dell 400-AEFB?
The combination of a generous storage capacity, robust performance metrics, and hot‑swap capability makes the Dell 400‑AEFB an excellent investment for organizations that demand both scalability and uptime. Its compatibility with a wide range of PowerEdge servers ensures that it can be integrated into existing infrastructures without extensive reconfiguration.
Whether you are expanding a current server’s storage pool or building a new high‑performance environment, the Dell 400‑AEFB 1TB Hot‑Swap Internal Hard Drive offers a reliable, efficient, and future‑proof solution that aligns with Dell’s commitment to enterprise excellence.
