4TB SAS 12Gb/s Server Drive

The Epoch 4TB 3.5-inch hard drive kit uses a SAS 12Gb/s interface and spins at 7200 RPM. It is built for Dell PowerEdge 12, 13 generation and Tower 12, 14 generation servers. The kit suits administrators who need reliable bulk storage in compatible enterprise chassis.

Tray Installation and Firmware

Each drive ships in a carrier that matches the hot-swap bays of the listed Dell models so mounting is a simple slide-and-lock action. The most common issue is a controller that lacks current firmware, which can prevent the drive from negotiating the full 12Gb/s link speed.

Controller and Bay Compatibility

Before ordering, confirm that your server backplane and RAID controller support SAS 12Gb/s drives and that the chassis accepts 3.5-inch hot-swap trays. Systems limited to 6Gb/s or fixed non-hot-swap cages will not work with this kit.
