FAQ

Q1: Best Speed Reported Here is 2800 MBytes/s --- that's equal to 22.4 Gbps -- Is it a Rip-Off?

No it’s not a rip off. 40 is Theoretical Speed, TB3 or TB4 actual speeds are at around 2500-2800 MBytes/s

Q2: Why Can't Reach Maximum Speed?

In any case, it needs to Reserve at least 18Gbps of available bandwidth for DP Signals, and it has the priority of allocating the remaining bandwidth. CERTAIN PERFORMANCE LOSS WAS BOUND TO OCCUR IN THE PROCESS OF DATA EXCHANGE.

Q3: What is the Difference Between Acasis Tbu401 & Tbu405 M1?

TBU405 M1 has BETTER HEAT DISSIPATION and SMALLER SIZE Than TBU401. AN UPGRAD VESION OF TBU401

Q4: Does this come with thermal pad？

Yes.
