DELL 400 GB SAS 12Gb/s 2.5" internal hard drive

Enterprise-grade SAS SSD for servers and arrays

This Dell 400 GB solid-state drive uses a 12 Gb/s SAS interface in a 2.5-inch internal form factor. It is built for hot-pluggable server bays and storage arrays that require dual-port SAS connectivity. The drive targets IT teams deploying transactional databases, virtualisation hosts or high-availability clusters where consistent low latency matters.

Sustained write performance in mixed workloads

Because the drive communicates over a 12 Gb/s SAS link, it maintains steady throughput during extended write-heavy phases such as log replay or checkpoint operations. The solid-state architecture avoids the rotational latency and seek penalties that mechanical disks exhibit once their caches fill. Hot-pluggable support lets administrators replace a drive without powering down the enclosure, keeping the array online during maintenance windows.

Compact 2.5-inch form factor with hot-plug tray

The 2.5-inch housing fits standard SAS backplanes and hot-swap carriers found in rackmount and blade servers. Dual-port SAS connectors on the drive mate directly with the backplane, providing path redundancy without extra cabling. This mechanical integration simplifies day-to-day operations such as capacity expansion or failed-drive replacement in production environments.
