DELL ST4000NM0023 4TB 7.2K SAS 3.5" internal hard drive

SKU CH-HVKB-NADF1 MPN ST4000NM0023

A 4 TB 3.5-inch SAS desktop drive spinning at 7.2K RPM for high-capacity storage

  • 4 TB capacity stores large datasets
  • 2 K RPM spindle delivers steady throughput
  • SAS 6 Gbit/s interface connects to enterprise controllers
  • 5 inch form factor fits standard drive bays
  • New condition ensures full manufacturer specifications

Capacity and interface

This is a 4TB 3.5" desktop internal hard drive with a SAS interface spinning at 7.2K. It suits servers or workstations that need high-capacity bulk storage on a SAS backplane.

Compatibility checks

Verify that your system has a free 3.5" drive bay and a SAS controller or HBA with a compatible 6G SAS port. Confirm the chassis provides the correct power connector for a 3.5" enterprise drive.

Upgrade context

The drive replaces a smaller-capacity SAS hard drive when more storage is required on the same interface. The jump is worth it when the existing array or bay count is full and a single larger spindle reduces device count.

Highlights

  • 4 TB capacity stores large datasets
  • 2 K RPM spindle delivers steady throughput
  • SAS 6 Gbit/s interface connects to enterprise controllers
  • 5 inch form factor fits standard drive bays
  • New condition ensures full manufacturer specifications

Questions about this item

Does the ST4000NM0023 4TB 7.2K SAS 3.5" drive ship with cables or a mounting bracket, or must they be purchased separately?

The drive is supplied as a bare unit; SAS data and power cables plus any 3.5" mounting hardware are not included and must be sourced separately.

Should I choose the 4TB 7.2K SAS model or a different capacity for a high-density storage server?

The 4TB 7.2K SAS variant balances cost per terabyte and rack density; select a larger capacity only if your chassis bays are limited and you need more raw space per slot.

What does the 7.2K RPM rating mean for real-world throughput in a RAID array?

At 7.2K RPM the drive delivers sequential throughput suited to bulk storage and backup workloads, while random I/O latency is higher than faster-spinning SAS drives.
