Four-bay Thunderbolt 3 RAID

The Promise Pegasus M4 is a 16 TB solid-state RAID enclosure that connects through a 40 Gbps Thunderbolt 3 link. It ships with four 2.5-inch enterprise SSDs configured by the PromiseRAID engine for sustained throughput above 2,000 MB/s. Creative professionals handling multi-stream video, 3D renders or large photo libraries gain a compact, high-endurance volume ready for macOS or Windows.

From single-drive or HDD RAID

Users moving from a single portable SSD or a hard-drive RAID array see a jump in both sustained bandwidth and drive endurance. The upgrade is worth it when project timelines demand consistent read and write performance across large datasets without the latency spikes of spinning media. Buyers who need more than 16 TB of raw capacity or who rely on internal PCIe expansion will not be served by this enclosure.

Desktop workflow integration

The silver-grey chassis occupies minimal desk space and includes an internal fan for thermal management. A single Thunderbolt 3 cable carries both data and host power, freeing up additional ports and reducing cable clutter. The unit requires a host with a Thunderbolt 3 port and a supported operating system; builders without that interface cannot connect it.

Questions about this item

What drive size does each of the four bays accept?

Each bay accepts a 2.5 inch SSD, and the enclosure ships with four 4 TB enterprise drives installed.

How do I initialise the RAID after connecting the Thunderbolt 3 cable?

Attach the Thunderbolt 3 cable, power on the unit, then launch the Promise Utility to create the array; skipping the utility leaves the drives unconfigured.

Can a failed drive be swapped without tools?

Yes — the bays are toolless, so a replacement 2.5 inch SSD can be inserted and the PromiseRAID engine will rebuild the array automatically.
