Mantiz Venus - Sep 2017 firmware with full 22xxMiB/s bandwidth (archive)
Just noticed Mymantiz_John has removed this full 22xxMiB/s bandwidth firmware from his blog. This firmware has been proving to be problematic with I/O ports as can be seen by user reports below:
- Mantis Venus – USB ports unusable
- Mantiz Venus – different SSD performance using enclosure ports versus Macbook ports?
In the first link above we see he has been reverting some users back to the previous 15xxMiB/s bandwidth firmware which statically allocates a large chunk of bandwidth for port use. This 22xxMiB/s firmware was supposed to dynamically allocate bandwidth for I/O ports as they needed it.
Some users want full eGPU bandwidth and don’t care for the I/O ports.
Thankfully we have his original blog firmware post announcement archived at http://archive.is/YV69Z , snippetted below and this full-H2D firmare attached.
Mantiz Venus New firmware is released
Mymantiz_John originally announced this upcoming firmware in July-2017:
Excellent to see those tests, I think the performance hit may come if you are running a game at High FPS / low quality where the transfer speed would be more of a bottleneck.
HI, Please check the bench mark by
Current FW: H2D 15xx Mib/S
Upcoming FW: H2D 22xx Mib/s
No difference in Low Quality & High FPS.
Please enjoy those extra Ports and its convenience. ＾＿＾
I’m using dynamic allocation firmware without issue on Sata and Ethernet. Sometime I got some USB-A he dusconnected but no issue with my mouse, iPhone dock and headset.
@dbuckingham , please see approx gaming FPS increases going from half-H2D to full H2D at:
