Dell 342-5755 300GB SAS drive

This Dell 342-5755 is a 300GB 2.5" SAS hard drive spinning at 10000 RPM with a 6Gb/s transfer rate. It ships new with a hot-swap tray included and is intended for server environments that use the SAS interface.

Server and storage builders

The drive suits administrators upgrading or repairing compatible Dell servers and storage arrays that accept 2.5" SAS drives with hot-swap trays. It is not for laptops or desktops that lack a SAS controller and hot-swap bay.

6Gb/s SAS interface

The single specification that decides fit is the 6Gb/s SAS interface; the system must provide a SAS backplane or controller that supports this signalling speed. Without a SAS connection the drive cannot be used.

Questions about this item

Does the 342-5755 drive ship with the hot-swap tray, or must the tray be purchased separately?

The hot-swap tray is included with the 342-5755, so no separate tray purchase is required for installation.

I only see a single 300 GB capacity listed; are there other capacities for this part number?

Part number 342-5755 is offered only in the 300 GB capacity; different capacities carry different Dell part numbers.

What real-world benefit does the 10 000 RPM speed give inside a server?

The 10 000 RPM spindle reduces rotational latency, delivering faster random read and write response for transaction-heavy server workloads.
