Dell 342-2066 450GB SAS Drive

The Dell 342-2066 is a 450GB 3.5" internal hard drive spinning at 15000 RPM. It uses a Serial Attached SCSI interface rated at 6Gb/s. The drive is supplied as a bare unit without a tray. It is built for server environments demanding high rotational speed.

Suited for high-transaction server workloads

This drive suits administrators deploying 15K SAS storage in compatible Dell PowerEdge servers or external arrays. It fits 3.5" hot-plug bays that accept a 6Gb/s SAS connection. Buyers needing larger capacity per spindle should evaluate other options. Systems limited to slower interfaces cannot use the full transfer rate.

15000 RPM spindle speed

The 15000 RPM spindle speed is the primary factor determining random I/O latency and sustained throughput. This rotation rate delivers the performance profile required for database logs and transaction-heavy applications. Verify that the target chassis and controller support 15K SAS drives before purchase.

Questions about this item

Will the 15000 RPM motor or SAS interface need servicing after long-term server use?

The drive is a sealed mechanical unit with no user-serviceable parts; the SAS interface is passive and requires no maintenance.

What limit appears first when the 15000 RPM drive runs sustained workloads?

The 6Gb/s SAS transfer rate caps throughput before the 15000 RPM platters reach their random I/O ceiling.

How much noise and heat does the 15000 RPM SAS drive produce during all-day operation?

Expect noticeable whine and measurable warmth from the 15000 RPM spindle; ensure the server chassis provides adequate airflow.
