RAID controller for multi-drive arrays

The RocketRAID 3720C adds eight SAS and SATA ports through a PCIe 3.0 x8 slot. It targets administrators building redundant storage on Windows Server, Linux or macOS 10.9 and later. The low-profile bracket fits compact chassis while exposing two SFF-8643 mini-SAS HD connectors for external enclosures.

Capacity and headroom

Each port delivers up to 12Gb/s, so eight drives can saturate the x8 link under heavy sequential workloads. RAID 0, 1, 5, 6, 1/0 and 5/0 are supported alongside JBOD and single-disk modes, though RAID 6 is unavailable on macOS. Online capacity expansion and level migration let arrays grow without downtime.

Thermals, noise and power

The card draws power solely from the PCIe slot and uses a passive heatsink, adding no audible noise to the system. Typical operating temperatures stay within spec for server environments when airflow passes over the 5.63" by 2.71" board. No auxiliary power connector is required.

Questions about this item

Will the PCIe 3.0 x8 RocketRAID 3720C run in my older PCIe 2.0 x8 slot?

Yes, the card is backward-compatible with PCIe 2.0 x8 slots; it will operate at 2.0 speeds while still providing eight 12Gb/s SAS/SATA ports.

How can I verify the controller is healthy after installation?

Use the Storage Health Inspector utility included with the driver package to monitor drive status, array health and controller firmware version.

What comes in the box and which cables must I source separately?

The package includes the low-profile controller card, a low-profile bracket and a quick installation guide; mini-SAS HD (SFF-8643) to SAS/SATA breakout cables are not included.
