Promise Technology Pegasus32 R4 16TB NAS 4x4TB

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.
