Frequently Asked Questions (FAQ)

Q1: What’s the advantage of USB 3.2 Gen2x2 (20Gbps)?

A: It ensures full-speed access to all four drives simultaneously, eliminating performance bottlenecks that occur with slower 10Gbps connections.

Q2: What is the maximum capacity supported?

A: Supports 88TB+ total using 4 x 22TB or higher capacity drives in JBOD mode.

Q3: Why choose JBOD over RAID 0?

A: JBOD offers safer data separation—if one drive fails, the rest are unaffected. RAID 0 offers speed but results in total data loss if any drive fails.

Q4: How does the Easy Data Vault app work?

A: It allows direct backup of iOS photos and videos to the enclosure, bypassing a PC or Mac for a simpler workflow.

Q5: What’s the benefit of having independent power switches?

A: They reduce power consumption, heat, and noise by allowing you to turn off unused drives, which also extends drive lifespan.
