3 TB SAS drive for PowerEdge servers

This 3.5 inch internal hard drive delivers 3000 GB of storage at 7200 RPM with a 6 Gb/s SAS interface and 64 MB cache. It ships new with a Dell PowerEdge caddy for direct installation in compatible server bays. The Constellation ES.2 design targets nearline workloads that demand consistent throughput rather than peak burst speed.

Upgrade from smaller nearline SAS drives

The 3 TB capacity replaces 1 TB or 2 TB SAS drives in PowerEdge R310, R410, R510, R710, T410 and T610 systems when storage density must grow without adding bays. The jump is worth it when backup windows, archive volumes or surveillance footage exceed the space of existing drives and the 6 Gb/s controller can sustain the stream.

Steady throughput under sustained load

At 7200 RPM the platters maintain sequential read and write rates across long transfers such as nightly backups or video ingest. The 64 MB buffer absorbs burst I/O while the SAS link keeps command queuing efficient during multi-threaded workloads. The drive is not for low-latency random access or boot volumes that need SSD response times.

Questions about this item

What drive bay and caddy does the 3.5" SAS ST33000650SS need to fit in a PowerEdge server?

It requires a standard 3.5-inch hot-swap bay and ships with the Dell PowerEdge caddy tray for tool-less insertion.

How is the ST33000650SS installed in a compatible PowerEdge, and which step is often missed?

Slide the caddy into the bay until the latch clicks, then verify the SAS backplane connector seats fully; the click is often mistaken for full seating.

What component of the ST33000650SS will need replacement after long-term operation?

The mechanical spindle and actuator assembly are the parts that wear out after years of continuous 7200 RPM operation.
