Frequently Asked Questions - Pegasus32 R4 Promise Technology
How do I set up the Pegasus32 R4 for the first time?
Connect the Thunderbolt 3 cable to your computer and the enclosure. Plug in the power adapter. Install the included Promise Utility software to configure RAID levels. Insert M.2 NVMe SSDs into the drive bays and follow the on-screen instructions.
What RAID levels are supported and which should I choose?
Supported RAID levels: RAID 0 (striping for speed), RAID 1 (mirroring for redundancy), RAID 5 (balanced), RAID 10 (striping+mirroring), and JBOD (individual disks). Choose based on your need for performance vs data protection. RAID 5 is a good general-purpose option.
Can I use SATA SSDs in the Pegasus32 R4?
No, the Pegasus32 R4 is designed exclusively for M.2 NVMe SSDs (2280 form factor). SATA M.2 drives are not compatible due to different interface and keying.
How do I replace a failed drive in a RAID array?
First, identify the failed drive via the status LED. Power down the enclosure. Remove the failed M.2 NVMe SSD and insert a new one of equal or larger capacity. Power on and use the Promise Utility to rebuild the array. The process is automatic for RAID levels with redundancy.
Is the Pegasus32 R4 compatible with Windows and macOS?
Yes, it works with both Windows 10/11 and macOS 10.13 or later. Thunderbolt 3 drivers are built into modern OS versions. Ensure your computer has a Thunderbolt 3 port.
What is the maximum capacity supported?
Each of the 4 drive bays supports an M.2 NVMe SSD up to 4 TB, giving a total maximum capacity of 16 TB. Capacities may vary as larger drives become available.
How do I clean and maintain the enclosure?
Use a dry, lint-free cloth to wipe the exterior. Ensure ventilation slots are free of dust. Do not use liquids or compressed air. Avoid placing the unit in direct sunlight or humid environments.
What should I do if the enclosure does not power on?
Check the power adapter connection and try a different outlet. Verify the Thunderbolt cable is securely connected. If the power LED remains off, contact Promise support for a replacement adapter.
Can I daisy-chain multiple Pegasus32 units?
Yes, the Pegasus32 R4 supports daisy-chaining via Thunderbolt 3. You can connect up to 6 devices in a chain, but performance may be affected depending on bandwidth.
Is the data on the drives encrypted?
The enclosure itself does not provide hardware encryption. However, you can use software encryption like BitLocker (Windows) or FileVault (macOS) on the volume created. Or use SSDs that support self-encryption.
