SKU CH-MK7D-Y6HSW

3 TB 3.5" SAS internal hard drive spinning at 7200 rpm with a 64 MB buffer

  • 3 TB capacity stores large data sets
  • 7200 rpm spindle speed enables fast data access
  • 64 MB buffer improves read and write throughput
  • SAS interface supports enterprise-grade connectivity
  • 5 inch form factor fits standard drive bays

Enterprise 3 TB SAS drive

The HGST Ultrastar 7K4000 is a 3.5 inch internal hard drive built for servers and storage arrays that demand consistent throughput. Its SAS interface suits environments where dual-port redundancy and enterprise firmware matter more than desktop convenience.

Sustained 7200 rpm operation

A 7200 rpm spindle and 64 MB buffer keep sequential transfers steady during long write sessions such as backup windows or video ingest. The mechanical design targets workload rates typical of nearline duties rather than bursty client workloads.

3.5 inch SAS mounting

The standard 3.5 inch form factor fits common hot-swap trays and fixed bays using the same screw pattern as other enterprise drives. SAS connectors provide locking cables that resist vibration disconnects in dense rack deployments.

Questions about this item

How much power and heat does the 7200 rpm Ultrastar 7K4000 generate during continuous operation?

The 3.5" SAS drive spins at 7200 rpm with a 64 MB buffer, typical for enterprise workloads where sustained throughput matters more than idle acoustics.

What host interface must my server or controller provide for the 0B26926 to function?

The drive uses a SAS interface, so a compatible SAS HBA, RAID card or backplane with SAS ports is required.

Can the 3 TB Ultrastar 7K4000 share a SAS backplane with older 2.5" or 3.5" SAS drives?

Yes, the 3.5" form factor and standard SAS connector allow it to operate alongside other SAS drives on the same backplane or expander.
