Enterprise 4TB SAS Hard Drive

The HGST Ultrastar 7K4000 is a new 3.5-inch internal hard drive with a 4TB capacity and a 7200 RPM spindle speed. It connects via a SAS 6Gb/s interface and includes a 64 MB buffer. The drive weighs approximately 1.52 lb and measures 5.8 inches in depth.

Suited for 7200 RPM SAS Environments Not

This drive suits administrators expanding SAS-based RAID or JBOD arrays who need 4TB of 7200 RPM capacity. It is not for builders whose host bus adapters or backplanes lack SAS connectivity. The 30-day manufacturer highlight indicates a limited evaluation window.

Deciding Specification SAS 6Gb/s Interface

The single specification that decides fitment is the SAS 6Gb/s interface. Your controller or backplane must support this exact standard for the drive to function. Without a compatible SAS host connection, the 4TB capacity and 7200 RPM speed cannot be utilised.

أسئلة حول هذا المنتج

Should I choose the 4TB Ultrastar 7K4000 or a different capacity?

This model provides 4TB of storage. Other capacities exist in the 7K4000 series but are separate part numbers; select the 4TB version when you need that exact amount of space.

What does the 7200 RPM spindle speed deliver in a real system?

The 7200 RPM rotation gives faster random access and higher sustained throughput than slower drives, benefiting workloads such as databases or multi-user file servers.

How does the SAS 6Gb/s interface limit performance in practice?

The drive uses a SAS 6Gb/s connection, which is the standard interface for this Ultrastar 7K4000 model and determines the maximum host transfer rate.
