Server Storage Capacity

This 8TB 3.5-inch hard drive uses a SATA 6Gb/s interface and spins at 7200 RPM. It is built for desktop and server bays that accept standard 3.5-inch SATA drives. The kit is validated for Dell PowerEdge 14th and 15th generation rack and tower servers.

Workload Fit

It suits administrators adding bulk capacity to compatible Dell PowerEdge R-series and T-series servers. Buyers who need a different drive interface or a smaller form factor should look elsewhere. The drive is not intended for laptops or compact enclosures that only accept 2.5-inch devices.

Deciding Specification

The SATA 6Gb/s interface determines whether this drive fits your server backplane or controller. Verify that your system supports 3.5-inch SATA hard drives before purchasing.

Questions about this item

Does the 7200 RPM spindle speed limit sustained write throughput under heavy server workloads?

The drive spins at 7200 RPM with a SATA 6Gb/s interface, so sustained write speed is bounded by the mechanical rotation and the SATA bus rather than a firmware throttle.

How much heat and noise does the 3.5" 8TB drive produce when running continuously in a Dell PowerEdge rack?

As a 3.5" 7200 RPM enterprise drive it generates typical mechanical noise and heat for its class; adequate chassis airflow in the supported PowerEdge servers keeps temperatures within spec.

Which drive carrier or caddy is required to install this drive in a 14G or 15G PowerEdge server?

The kit is a replacement drive for the listed Dell PowerEdge 14G and 15G models; you must use the server's original 3.5" hot-plug carrier for proper fit and connection.
