The Promise Pegasus M4 combines the robust PromiseRAID engine with the high throughput of Thunderbolt in a compact, four-bay all-SSD enclosure, purpose-built for creative media professionals who need mobile, high-performance storage.
Four pre-installed, enterprise-level high-endurance SATA SSDs deliver low-latency performance well suited to 4K and 8K ingest, playback, and postproduction work, with Pegasus M4 maximizing SSD speed while maintaining enterprise-level RAID data protection, delivering over 2,000MB/s with low latency.
Dual Thunderbolt 3/4 ports support daisy-chaining for expanding a storage setup, while a 10Gbps USB 3.1 Gen 2 fallback maintains compatibility with systems that lack Thunderbolt. An integrated SAS ROC (RAID-On-Chip) processor paired with 1GB of DDR3 1866 ECC memory ensures stable, high-performance operation even under sustained workloads.
Pegasus M4 is a perfect match for the Mac Studio, with compatibility spanning macOS 12 and 13 with Apple M1 and M2 CPUs, Intel x86 systems, and Windows and Linux via driver support, giving creative teams flexibility across their existing hardware.
Intelligent cooling and acoustic control keep operation whisper-quiet, while Drive S.M.A.R.T. health polling proactively monitors drive condition, and support for RAID 0, 1, 5, 6, 10, and JBOD configurations lets users balance speed against redundancy to match their specific workflow.
