DELL ST3000NM0023 3TB 7.2K SAS 3.5" internal hard drive

SKU CH-3JNY-EY8M5 MPN ST3000NM0023

3.5-inch SAS hard drive with 3 TB capacity, 7200 RPM speed and hot-swap support for server storage arrays

  • 3 TB capacity stores large enterprise datasets
  • 7200 RPM spindle delivers consistent server throughput
  • SAS interface enables dual-port redundant connectivity
  • Hot-swap tray allows drive replacement without downtime
  • 5-inch form factor fits standard server bays

3 TB SAS server drive

This 3 TB hard drive uses a SAS interface and spins at 7200 RPM. It is built for servers and storage arrays that require hot-swap capability. The 3.5-inch form factor fits standard enterprise drive bays. It is not intended for home desktop computers.

Sustained enterprise workloads

The 7200 RPM spindle speed delivers consistent throughput for multi-user environments and RAID sets. SAS signalling provides dual-port redundancy and better error recovery than single-port links. Hot-swap support allows drive replacement without powering down the chassis. Performance scales with the number of drives in the array.

Replaces smaller SAS spindles

This drive upgrades from lower-capacity 7.2K SAS units when more space is needed in the same bay count. The jump makes sense when storage density per rack unit becomes the limiting factor. Buyers who need SATA-only connectivity or desktop-class workloads should look elsewhere.

Questions about this item

How much power does the 7200RPM SAS drive draw during all-day operation?

The 3.5-inch enterprise drive is rated for 7.2K RPM spindle speed and a 6G SAS interface, which together define its steady-state power profile in a server chassis.

What controller or backplane must I already have for this SAS drive to work?

You need a 6G SAS host bus adapter or a SAS expander backplane that accepts 3.5-inch hot-swap carriers; the drive will not function on a SATA-only motherboard port.

Will the ST3000NM0023 share a SAS backplane with older 3G SAS or SATA drives?

Yes, the 6G SAS interface auto-negotiates down to 3G speeds, so the 3TB drive can sit alongside legacy SAS or SATA disks on the same backplane.
