SKU CH-X21W-6T952

A 4 TB enterprise hard drive with 7200 RPM, 12 Gb/s SAS interface and 128 MB cache for high-capacity server storage

  • 4 TB capacity stores large enterprise data sets
  • 7200 RPM spindle delivers fast sequential throughput
  • 12 Gb/s SAS interface enables high-speed host connectivity
  • 128 MB cache buffers heavy random workloads
  • 5 inch form factor fits standard server bays

Enterprise SAS storage

The Seagate ST4000NM0034 is a 4TB enterprise-class internal hard drive built for 3.5in drive bays. It spins at 7200RPM and connects through a 12Gbps SAS interface with a 128MB cache buffer. The drive uses 512e sector formatting and is supplied as a bare unit without mounting accessories.

Suited for SAS arrays

This drive fits servers and storage enclosures that provide native 12Gbps SAS ports and 3.5in hot-swap or fixed bays. It is not suitable for systems that lack a SAS controller or backplane, nor for compact chassis that only accept 2.5in form factors.

12Gbps SAS interface

The single specification that determines compatibility is the 12Gbps SAS interface. The host system must support this exact protocol and connector type for the drive to function.

Spurningar um þessa vöru

Does the Seagate ST4000NM0034 ship with cables or a mounting kit, or is it a bare drive only?

The drive is supplied as a bare unit only. You will need to provide your own SAS data and power cables plus 3.5" mounting screws or a drive tray for installation.

The listing shows a single 4TB capacity — are there other capacities or speed variants of this exact model to choose from?

This MPN ST4000NM0034 is fixed at 4TB with a 7200RPM spindle and 128MB cache. Different capacities or speeds carry different model numbers and are separate products.

What real-world throughput can I expect from the 12Gb/s SAS interface once the drive is in a server or RAID controller?

The 12Gb/s SAS link provides up to 12Gb/s bus bandwidth. Sustained transfer rates are limited by the 7200RPM mechanics and 128MB cache, typically delivering sequential speeds well below the interface maximum.
