Server-Ready 600 GB SAS Drive

The Dell 342-2056 is a 3.5 inch internal hard drive built for server environments. It spins at 15000 RPM with a 16 MB cache and connects through a SAS interface. The bare-drive unit arrives new and is suited to high-demand storage arrays.

Suited to Enterprise Arrays

This drive fits servers and storage systems that accept 3.5 inch SAS drives running at 15000 RPM. Buyers whose chassis only accepts 2.5 inch bays or who require a different interface cannot use this model. Systems limited to lower spindle speeds will not match its performance profile.

15000 RPM Spindle Speed

The 15000 RPM rotation rate is the specification that determines whether this drive meets the throughput and latency needs of the target workload. Verify that the host controller and backplane support this speed before purchase.

Questions about this item

Which capacity and speed combination should I choose for a server storage upgrade?

This drive provides 600GB capacity with a 15000 RPM spindle speed and 16MB cache, designed for server workloads.

What does the 15000 RPM figure mean once the drive is installed in a server?

The 15000 RPM rotation reduces average latency to 12Gb/s, delivering faster random access for transaction-heavy applications.

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

The SAS 3Gb/s interface limits the maximum transfer rate to 3Gb/s, even though the drive itself is rated for 6Gb/s transfer speed.
