This dual-control system (manual and automatic) ensures optimal cooling while maintaining efficient operation.
The compatibility of Thunderbolt 3 computers with Thunderbolt 5 interfaces is not that good. They will be automatically classified as USB channels if they are not compatible. In this case, we recommend you use Thunderbolt 3 hard drive enclosures if you use Thunderbolt 3 computers. A Thunderbolt 3/4 40Gbps hard drive enclosure will be faster if the USB channel is recognized.
