Enterprise SAS drive

The Seagate ST1000NM0023 is a 3.5 inch internal hard drive with a SAS interface. It spins at 7200 RPM and provides 1 TB of capacity with a 128 MB cache. The Constellation ES.3 line is built for server and storage arrays that require hot swap and removable drive support.

Who this suits

It suits administrators deploying SAS attached storage in compatible server chassis or external enclosures. It is not for builders whose host bus adapter or backplane lacks SAS connectivity. It is also not for buyers who want more storage than the single terabyte this model delivers.

Deciding specification

The SAS interface is the single specification that decides compatibility. A SAS controller or backplane with matching physical and electrical connectors is required for the drive to function. Without that interface the drive cannot be used.

Highlights

  • 7200 RPM spindle speed delivers consistent throughput
  • 128 MB cache accelerates frequent data access
  • Hot-swap support enables drive changes without downtime

Questions about this item

Should I pick the 1 TB SAS model or a larger capacity for my server array?

The ST1000NM0023 provides 1 TB of storage; choose it when your array requires this exact capacity and the 7200 RPM spindle speed matches the workload profile

What does the 7200 RPM figure mean for actual throughput in a RAID enclosure?

The 7200 RPM spindle combined with 128 MB cache delivers consistent sequential and random I/O performance suited to near-line server workloads

Which SAS interface standard does this drive use and what speed does it cap at?

The drive uses a SAS interface operating at 12 Gbit/s, which sets the maximum host transfer rate for the device
