HPE 4TB 12Gb/s SAS Enterprise Drive

This HPE 833928-B21 is a 4TB 3.5" internal hard drive built for enterprise and midline workloads. It spins at 7200 RPM and connects through a SAS 12Gb/s interface with an average seek time of 8.5ms. The drive is supplied new in a hot-swap carrier.

Suited for high-transaction servers and arrays

Buyers who need a 12Gb/s SAS connection for high-availability storage will find the correct interface and form factor here. Builders whose chassis or controller only accept 2.5" drives or a different interface cannot use this part.

The SAS 12Gb/s interface decides compatibility

The drive requires a backplane and controller that support 12Gb/s SAS signalling. Without that link the drive will not function, so verify the host system provides a SAS 12Gb/s connection before purchase.

Questions about this item

How do I install the 833928-B21 in a hot-swap 3.5" SAS bay?

Slide the drive into the carrier until the connector seats firmly on the 12Gbps SAS backplane, then lock the lever; the step most people miss is not fully engaging the carrier latch, which leaves the drive loose and causes connection errors

What maintenance will the 4TB 7200 RPM drive need later?

No scheduled maintenance is required; monitor SMART attributes for reallocated sectors and rising seek times, and replace the unit once the error counters approach the manufacturer thresholds

What limit appears first when the 12Gbps SAS drive runs sustained writes?

The 7200 RPM spindle caps sequential throughput at the media transfer rate, so sustained write streams hit the mechanical speed ceiling before the 12Gbps interface saturates
