Dell 342-5816 SATA SSD

This Dell 342-5816 is a 400GB solid-state drive with a 2.5 inch form factor and a SATA 6.0Gb/s interface. It ships as a bare drive with a hot-swap tray included. The unit suits desktop owners who need a direct replacement for a failed Dell drive or who want a straightforward capacity boost on a SATA backplane.

Sustained write behaviour

As an SSD connected through SATA 6.0Gb/s, the drive delivers consistent throughput without the thermal throttling that affects mechanical disks during long transfers. Write speeds remain stable across large sequential jobs such as backups or video ingest because there are no moving heads to reposition. Random I/O latency stays low and predictable under mixed workloads typical of desktop operating systems.

Installation and common issues

The 2.5 inch form factor fits standard drive bays and the supplied hot-swap tray allows tool-less insertion into compatible Dell chassis. Installers must verify that the target system provides a SATA data and power connection for a 2.5 inch device. The bare-drive packaging means no mounting screws or cables are included, so reuse existing hardware or source them separately.

Questions about this item

How much power does the Dell 342-5816 400GB 2.5" SATA 6.0Gb/s SSD draw during all-day operation?

As a solid-state drive with no moving parts, it typically consumes only a few watts under load and idles well below one watt, producing minimal heat and zero audible noise.

What connector and tray does my server or array need to accept this Dell 342-5816 drive?

It requires a standard SATA data and power backplane plus a 2.5" hot-swap bay; the included hot-swap tray fits Dell PowerEdge and compatible enclosures.

Will this Dell 342-5816 400GB SATA SSD work in a system that only supports 3Gb/s SATA links?

Yes, the SATA 6.0Gb/s interface negotiates down to 3Gb/s automatically, so the drive functions normally on older controllers.
