HDD raid using modded boards into Mantiz Venus

I start this topic, as nando4 asked, to update my results in making RAID configurations.

 

Uptonow I tried to adapt a tiny dual M.2 Sata enclosure with USB-C Gen2 interface to use it with normal Sata HDD.

It works well!

I used these:

http://www.ebay.it/itm/HDD-BOX-ESTERNO-USB-3-1-PER-DISCHI-DUAL-M-2-6G-SSD-CON-RAID-PORTA-USB-TYPE-C/272714051895?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

and

I connected 2 6TB HDD and used its USB-C to USB 3.1 cable on a 3.1 (Gen1) port and you can see the HDD in the pc. Made a Storage Space of them, similar to Raid0, I got these, with a real copy:

Reading: 404MB/s

Writing: 408MB/s

Now, I'm waiting for Mantiz to put other 2HDD into this setup: I'll tell you.

 

My question, now is this:

I tried to connect the enclosure to the TB3 port of my Asrock mini-itx Z270 Fatal1ty that should use that port even in USB-C Gen2 mode. I enabled on BIOS the TB3.

I used the same cable with this adapter:

https://it.aliexpress.com/item/Factory-price-USB-C-3-1-Type-C-Male-to-USB-3-0-Female-Adapter-for/32547318260.html?spm=a2g0s.9042311.0.0.Ht26OY

It shows only the HDD units (disk1 etc) and its letter, but NOT the Volume Name and also its not accessible, the system hung up.

Can my MB use USB-C for HDD in the TB3 port?

Is it a problem of the USB-C to USB-A adapter?

Should it work with a direct USB-C USB-C cable?

TIA

I bought this USB-C Gen2 cable, 2m:

http://www.ebay.it/itm/InLine-USB-3-1-Kabel-Typ-C-Stecker-Stecker-PD2-0-10Gb-s-HDD-Grafikkarten-2m/162216089706?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

I tried and had the same result as with the original USBC-USB3.0+adapter to USB-C: it does not correctly recognize the device.

 

So, I asked Asrock tech some clarification and they answered this:

According to your description, seems like the symptom will only happen when connecting 2M USB-C cable.
 
Base on association definition, USB3.1 type-C cable length needs to less than 1 meter.
If above 1 meter length, it will get poor signal and other side effects.
For system stability, we would suggest connecting the HDD with its cable.
 
If you really want to use another cable, please purchase which passes the Intel THUNDERBOLT certification mark products as attached photo.
 
To me that makes no sense.
A TB certificated cable, especially the long ones, active, WILL NOT give any USB-C only connection as they work only at max at USB2.0...
 
For the 2m cable, I don't know, on wiki they said Gen2 max 1m, Gen1 even 2m, so eventually, I should only see a loss on the speed I think...
What do you suggest me?

@Franketto. the Macbook TB3 port supplies three protocols: TB3, USB 3.1 Gen2 and DP 1.2. When attaching your storage enclosure to the USB 3.1 Gen2 port, you will require a cable capable of the USB 3.1 Gen2 10Gbps transmission speed.

Well, I'm not sure of this thing: I can use that unit without problem, with its cable that is a USB-C to USB3.1 cable, BUT I connected on my USB3.1 ports that are all 3.1 *Gen1*... and all is working well.

So, I think it's possible to connect also in Gen1 mode.

Anyway, the 2m USB-C cable I bought, is it out of standards? As it is sold as a Gen2 10Gb/s cable!! I bought just for that!

1m and longer active cables do not support USB3.0 or USB3.1 protocols, just the USB2.0 (480Mbit/s).

However, if you transfer data through TB3 protocol, theoretical 22Gbps PCIe SSD read performance is possible with longer active cables.

I know that long *TB* cable cannot support USB-C Gen2, but only USB2.0: I wrote it previously.

The point is, I bought a NON TB cable, but a specific USB-C *ONLY* cable that is specified as a USB-C Gen2 10Gb/s as my previous link.

I will use this USB-C only cable with devices not TB, whilst I will use eGPU with anotehr different appropriate TB3 cable.

BTW,

I have also a 2m Caldigit TB3 cable that I could use.

But as said it's only a USB2.0 capable speed, I don't know if it will recognize the unit...

Could this active cable damage things?

Sorry, I misunderstood as you said "to me that makes no sense". My advice was just to use a passive 0,5m TB3 cable if you want the best USB compatibility with TB3 ports.

No problem, yes you are right and also the Asrock answer IF I will buy a PASSIVE Tb cable. Ok.

But my point is I would like to connect eGPU at 2m long if I can for noisy. So, active TB cables solve this for TB part.

It remains the USB-C connection problem, as I would put that external box unit inside the Mantiz eGPU to connect with another cable to pc for HDDs.

So, I thought I will use dedicated USB-C 2m cables... but this seems causing problems.

Possibilities I must verify:

1) MB port is broken

2) USB-C can work at 2m BUT MY cable can't

3) USB-C works with USB-C only shorter cable OR TB passive shorter (I will bought the cheapest...)

4) is it really a USB-C standard that prohibites 2m cables? If this is true there are a lot of cable out of specifics out there

Sadly at the moment I have not another pc with USB-C to test...

 

Anyway do you suggest another cheap shorter cable to test this thing? which brand?

The cheapest USB-C cable I found is this 1m:
https://www.amazon.it/Inateck-rivestito-Alluminio-dispositivi-Nintendo/dp/B073RY5JZ3/ref=sr_1_fkmr3_3?ie=UTF8&qid=1504871285&sr=8-3-fkmr3&keywords=cavo+usb-C+gen2+10Gb

Do you think it could go well to try at least if the USB-C MB port is working?
   
Or this Anker, slightly costly 90cm:
https://www.amazon.it/Anker-Powerline-supporto-Delivery-Nintendo/dp/B072JYDQ7N/ref=sr_1_24?ie=UTF8&qid=1504871634&sr=8-24&keywords=cavo+usb-C+gen2?

The TB cables 1m are all over 70€ !! And also those are active... I can't find TB3 passive cables 40Gb of 1m!
I don't want to buy one of 0,5m, as when I'll buy Mantiz it's included.
