400-ATIO - Dell 600Gb SAS 12G 15K SFF HDD in LFF R/T-Series Tray - DPN - Gen 14

The Dell 400-ATIO 600GB 15K SAS drive is a high-performance internal hard disk built for enterprise environments where speed, reliability, and uptime are critical. With a capacity of 600 GB, this drive provides a balance between usable space and fast access times, making it suitable for mission-critical applications such as database servers, virtualization hosts, and online transaction processing. Its design targets data centers and enterprise class PowerEdge servers where consistent performance under heavy loads is essential.

High-Speed Interface & Throughput

This model uses a 12 Gbps Serial Attached SCSI (SAS) interface, which offers superior throughput, error recovery, and reliability compared to consumer-grade interfaces. SAS is a preferred choice in enterprise storage due to its ability to maintain high sustained transfer rates and handle concurrent I/O tasks efficiently. The fast interface ensures that data flows quickly between the drive and server controllers, enhancing responsiveness in virtualized and high-performance workloads.

15,000 RPM Spindle for Rapid Access

At the core of this drive's performance is its 15,000 RPM (15K) spindle speed, which dramatically reduces average seek times and rotational latency compared to lower-speed drives. This high rotational speed allows the drive to return data fast, which is especially beneficial for frequently accessed datasets, transactional databases, or environments where performance consistency outweighs sheer capacity.

Compact Form Factor with Hybrid Carrier

The drive itself uses a 2.5-inch form factor, which is ideal for dense server environments and efficient use of space inside blade or rackmount chassis. To support wider compatibility with server backplanes that expect larger drive bays, the unit is typically supplied in a 3.5-inch hybrid carrier or caddy. This hybrid design allows the smaller SAS drive to fit securely into traditional 3.5″ hot-plug drive bays, enabling easy installation and replacement without powering down the system.
