I'm looking for a good USB controller 3.0,4 ports,self powered compatible with FreeBSD....

As Phishfry observed, the PCIE 2.0 x1 slot has limited bandwidth, and the tech specs on the SENDA card you mention specify "Single-lane (x1) PCI Express Throughput Rates Up to 4.8Gbps". That's not a lot of bandwidth for 4 x USB 3.0 ports (SATA disks are generally rated at 6.0 Gbps each).
 
If OP can get stuff from amazon.co.uk, that's probably his best bet. I didn't have a good experience with aliexpress (bought a wi-fi card for my previous laptop, only to discover that they shipped the wrong brand). And - go with established brand names. For compatibility with FreeBSD - these forums are a decent place to ask, they will point to the hardware notes that the FreeBSD project maintains. Established names, brand-new (not second-hand) are frankly a good bet. Yeah, you pay a bit more, but peace of mind is priceless, IMHO.
 
I can buy on Amazon.com. I do this frequently. So,if someone can share the link where I can get a good USB controller that hasn't any PCIE 2.0 x1 slot,he will make me happy :D

If you want PICe 3.0 or 4.0, just type the term into the search bar of Amazon. Amazon is prone to having search results polluted by sellers who pay more to have their wares float to the top - but persistence pays off. Play with your search terms until you find what you need - I do that for my purchases. :)

Man,I don't stay with my hands in my hand. I'm doing that already,but I didn't find anything good right now.
 
FreeBSD may not work well with USB 3.1,as someone doubted yesterday in a post correlated to this. So,if it may not support USB 3.1,could it supports 3.2?

Try this search term: "usb 3.0 pcie expansion card" (w/o the quotes). One good example (I'm based in US): https://www.amazon.com/Tiergrade-Superspeed-Expasion-15-Pin-Connector/dp/B07Z34BJYH/ref=sr_1_3?crid=1U9EOCFSIAI7&keywords=usb+3.0+pcie+expansion+card&qid=1639496076&sprefix=usb+3.0+pcie,aps,277&sr=8-3 If I were to buy that, I would have confidence it would be compatible with FreeBSD (My install has 13-RELEASE).

What covacat gave you is an Italian Sausage ;)
(In US, 'links' also means 'sausage')

The terms USB 3.1 and USB 3.2 are pretty meaningless without adding the Generation number.

As I suggested above, you probably want to stick to USB 3.1 Gen 2, and USB 3.2 Gen 2 (the latter is faster, and less common, but the two standards are compatible). These specifications need to be matched between your USB disks and the PCIe card.

I suggest that you address the issues one at a time:
  1. What is your final disk configuration? Are you using RAID of any kind? Is redundancy important? Is performance important? Or do you just want low cost?
  2. What is the maximum power consumption of each USB disk? You need to match this to the wattage available on each USB port. If those data are not on the manufacturers' technical specification sheets, you need to contact their technical support, and find out. By doing this, you also test their service capability.
  3. What version PCIe bus do you have on the motherboard? The most common answer is 3.0, but could be anything from 1 to 5. This will determine some bandwidth limitations.
  4. How many free PCIe slots are there on your motherboard, and how many lanes do each of them have (look at what's actually installed, and the diagrams in the motherboard manual).
For optimum price, performance, and redundancy of four USB disks I would choose two dual port 4-lane (x4) PCIe cards, but they still need to fit into the motherboard (two x4 slots required). As I indicated above, I have tested the StarTech PEXUSB312A2 card on FreeBSD and it worked well. If PCIe x4 slots are at a premium, you can pay more and get something with 4 USB ports on a single card that would probably work well. Note the option for separate power supply to the 4-port card providing for up to 900mA (4.5W at 5V) per USB port. Most USB ports can supply 2.5W at best...

StarTech USB 3 cards are very widely available. You just have to use search engines. That includes the ones on Amazon and Google.
 
I don't know how's the law in Italy but here in Germany we can send back stuff we ordered on the Internet within two weeks without any reason and get our money back.
If this applies to Italy as well, i'd order both and test the hell out of them. Then send the one back you don't like.

Didn't know there's such a law in Germany... in US, it's standard business practice to give a week or two for "No questions asked" returns (although on Amazon, that practice has suffered a lot of abuse from customers who buy clothes just to wear to a party). I'd rather do my homework, find what I want, and then not fuss with sending it back. After all, you still gotta package it properly for shipping it back, and that is an effort I'm too lazy for. :P

Never did that. I don't like to "play" with returns.

Exactly. In addition im not vaccinated. I can't go all around the city because I don't have the green cazz. People like me can only go to some few specific places,like pharmacies, hospitals, supermarkets. stop.
 
Still not vaxxed? Consider this: If you wear a boxing glove to punch a bag, you can still end up with bloody knuckles. But without the glove, your entire hand will be crushed, bones, muscles and everything. Getting vaxxed is like putting on boxing gloves - yeah, there's some protection for you, and it's much better than nothing. Boxing gloves are required equipment to participate in the sport, vaccination is required to participate in person-to-person interaction. FWIW, boxers are supposed to be vaccinated to fight anywhere on this planet. So, just take it on the chin, and go get it.

but I don't have so much relationships with other people,so I don't need it. and for the very few ones I have,I keep the distance and I wear a strong mask. I'm scared by the bad side effects of the vaccination. It's a stronger fear than the fear to get the covid. so...
 
I'm scared by the bad side effects of the vaccination.
Close to 11 billion doses have been given world-wide and nothing major has happened. Only an extremely small portion of the population have had any adverse side-effects. And most of those have only been temporary.
It's a stronger fear than the fear to get the covid.
Rational fear is fine, irrational fear however is not. You have an irrational fear.
 
Making a rational decision means that you have to sensibly evaluate the risks -- or at least obtain your information from sensible sources.

Vaccines have a tiny risk. So does breathing. Both have considerable benefits. But when you get a vaccine, the benefits accrue to yourself AND those around you.

“More people are killed every year by pigs than by sharks, which shows you how good we are at evaluating risk.” -- Bruce Schneier
 
I've bought this cheap card model :

I haven't still tested it. Regarding the vaccination and the covid : I agree with you,the risk of a bad side effect is tiny,but I don't want to take it. If the risk is tiny,some of the effects can have a very bad impact on health : I’m talking about blood coagulation problems, neurological problems, immune system failure, heart problems. No,thanks.
