It supports RAID levels 0, 1, 10, 3, 5, 6, 30, 50, 60, JBOD, and single disk configurations.


Connectivity and Expansion

Dual Thunderbolt 3 ports deliver up to 40Gbps bandwidth, with support for daisy-chaining up to six devices.

An additional DisplayPort enables 8K 30Hz video output, and USB 3.2 Gen 2 ensures broad compatibility.

The 120TB model includes 12 x 10TB 7200rpm enterprise SAS/SATA drives pre-installed in a 12-bay desktop chassis.

Internal interfaces support 12 x 12Gb/s SAS or 6Gb/s SATA ports for high-throughput storage arrays.


Performance and Reliability

8GB DDR4-2666 SDRAM with ECC protection safeguards data integrity during intensive operations.
