Server Storage Drive

The Dell TN937 is a 146GB 3.5-inch internal hard drive built for server environments. It operates at 15000 RPM with a 16MB cache and connects via a SAS 3Gb/s interface. This bare drive is supplied new and designed for high-speed data access in compatible bays.

Workload Fit

This drive suits administrators who need fast mechanical storage for transaction-heavy workloads or database logs. It is not intended for desktop PCs lacking a SAS controller or hot-swap backplane. Buyers requiring larger capacities or solid-state endurance should consider alternative storage types.

Interface Decides

The SAS 3Gb/s interface is the single specification that determines compatibility. The system must provide a matching SAS port and support 3.5-inch hot-swap trays for this drive to function. Without that connection, the drive cannot be installed or used.

Questions about this item

How do I decide between the 146GB capacity and other sizes for my server?

This drive provides 146GB of storage on a 3.5-inch SAS tray designed for hot-swap server bays.

What does the 15000 RPM speed deliver in a live server?

The 15000 RPM spindle and 16MB cache give low latency for transaction-heavy workloads such as databases or email queues.

What does the SAS 3Gb/s interface limit in practice?

The SAS 3Gb/s link sets the maximum bus bandwidth, so the drive cannot exceed that transfer ceiling on any backplane.
