  • 2 TB capacity stores large datasets
  • 7200 RPM spindle delivers fast sequential access
  • 12 Gb/s SAS interface supports high-throughput workloads
  • 128 MB cache buffers burst I/O
  • 5 inch form factor fits dense server bays

Dell Enterprise 2.5" SAS HDD

The Dell Enterprise ST2000NX0433 is a 2.5-inch internal hard drive with a 12 Gb/s SAS interface. It operates at 7200 RPM and provides a 128 MB cache buffer. The drive ships new with an included R Series caddy tray and reports zero operating hours.

Suited for 12 Gb/s SAS bays

This drive fits servers or arrays that accept 2.5-inch SAS drives running at 12 Gb/s. Buyers needing a different physical size or a slower interface should look at other options. Systems without SAS controllers cannot use this drive.

Capacity is 600 GB

The manufacturer data lists the formatted capacity as 600 GB despite the 2 TB model designation. Verify that this capacity meets the storage requirement before purchase. The 12 Gb/s SAS speed and 7200 RPM spindle rate support the stated performance profile.

商品問答

How do I install the 2.5" SAS drive and its R Series caddy into a Dell server bay, and what step is often missed?

Slide the drive into the supplied R Series caddy until the connector seats firmly, then insert the assembly into the hot-swap bay until the latch clicks; the step often missed is fully engaging the latch so the 12Gb/s SAS link trains at full speed.

What maintenance or replacement will the ST2000NX0433 need during its service life?

No scheduled maintenance is required; monitor SMART reallocated-sector counts and replace the drive if the 128MB cache cannot hide growing read latency or if the 7200RPM mechanism develops bearing noise.

What limit appears first when the drive runs sustained writes at 7200RPM over a 12Gb/s SAS link?

The 7200RPM platter speed caps sequential throughput well below the 12Gb/s interface ceiling, so sustained write performance hits the mechanical media rate first.
