Ready-to-use 16 TB desktop NAS

The Promise Technology Pegasus32 R4 ships with four 4 TB 7200 rpm SATA drives preconfigured in RAID 5, delivering 16 TB of protected storage for video editors and creative professionals who need immediate capacity. Dual Thunderbolt 3 ports and a USB 3.2 Gen 2 connection provide flexible host connectivity at up to 40 Gbps or 10 Gbps respectively. The unit supports RAID 0, 1, 5, 6, 10, 50, 60 and JBOD for tailored performance or redundancy.

Host port and daisy-chain checks

Verify that your workstation offers a Thunderbolt 3 port for full 40 Gbps throughput or a USB 3.2 Gen 2 port for 10 Gbps operation; Thunderbolt 2 Macs require an adapter. Confirm your operating system is a supported macOS or Windows release for driver compatibility. Ensure you have a free Thunderbolt port if you plan to daisy-chain up to six Pegasus32 units or drive an 8K display via DisplayPort 1.4.

Thermals, noise and power in use

Four spinning 7200 rpm drives generate audible seek noise and measurable heat during sustained 600 MBps transfers, so place the chassis on a stable surface with unobstructed airflow. The internal power supply delivers up to 85 W to a connected Mac while powering the array, so factor this draw into your workstation power budget. Fan speed ramps with drive temperature, remaining moderate during typical editing sessions.

Questions about this item

What comes in the box and do I need to buy drives separately?

The unit ships with four 4 TB 7200 rpm SATA hard drives pre-installed and preconfigured in RAID 5, so no additional drives are required for the 16 TB capacity.

Which RAID level should I choose for video editing versus archival storage?

RAID 5 is set by default and balances speed with single-drive fault tolerance; RAID 0 maximises throughput for scratch files, while RAID 6 or 10 adds a second parity or mirror for critical archives.

What does the 600 MBps transfer figure mean when I am editing 4K footage on a Thunderbolt 3 Mac?

It represents the sustained sequential read or write ceiling the four-drive array can deliver over the 40 Gbps Thunderbolt 3 link, letting you stream multiple 4K ProRes streams without dropped frames.
