Designed for content creators and pro users who need additional GPU, I\/O, or accelerator cards, Echo II DV leverages Thunderbolt 5 bandwidth to deliver up to 6000 MB\/s of PCIe bandwidth per Thunderbolt 5 port when the host provides separate 80 Gbps buses. The result is a seamless way to supercharge M4 Pro, M4 Max, and M3 Ultra Apple systems and other Thunderbolt 5 hosts with demanding workflows, without sacrificing responsiveness or card compatibility.\u003c\/p\u003e\n\u003ch3\u003eFeatures and Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eDual‑slot desktop PCIe expansion chassis supports two PCIe cards simultaneously.\u003c\/li\u003e\n\u003cli\u003eThunderbolt 5 connectivity providing up to 6000 MB\/s PCIe bandwidth per Thunderbolt 5 port (when host supplies separate 80 Gbps buses).\u003c\/li\u003e\n\u003cli\u003eOptimized for high‑performance hosts such as Apple systems with M4 Pro, M4 Max, and M3 Ultra.\u003c\/li\u003e\n\u003cli\u003eEnables significant workflow expansion—add I\/O, or accelerator cards to compatible Thunderbolt 5 systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eProduct Q\u0026amp;A\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eQ:\u003c\/b\u003e How many PCIe cards can the Echo II DV Desktop accommodate?\u003cbr\u003e\u003cb\u003eA:\u003c\/b\u003e It supports two PCIe cards simultaneously (dual‑slot desktop chassis).\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eQ:\u003c\/b\u003e What performance can I expect from the Thunderbolt 5 ports?\u003cbr\u003e\u003cb\u003eA:\u003c\/b\u003e The product description states up to 6000 MB\/s of PCIe bandwidth per Thunderbolt 5 port when connected to hosts that provide separate 80 Gbps Thunderbolt buses (for example, certain MacBook Pro, Mac mini, and Mac Studio configurations with M4\/M3 chips).\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eQ:\u003c\/b\u003e Which computers are explicitly mentioned as supported in the product text?\u003cbr\u003e\u003cb\u003eA:\u003c\/b\u003e The description calls out Apple computers with M4 Pro, M4 Max, and M3 Ultra (examples: latest MacBook Pro, Mac mini, Mac Studio) when those systems expose multiple Thunderbolt 5 ports on separate buses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eQ:\u003c\/b\u003e Will this work with a Thunderbolt 4 or earlier host?\u003cbr\u003e\u003cb\u003eA:\u003c\/b\u003e The provided information emphasizes Thunderbolt 5 performance.
