USB 3 card

[Namiga]

Good afternoon.
It doesn't seem to have much to do, but it would really be used to transfer photos and videos

A small question.
I have an HP Z400 workstation and I'm thinking of buying a USB 3.0 card to speed up file transfers.

I would like to know if any of you have bought a USB 3.0 card, tell me the brand and model and what its performance is.

I've seen prices from 9 € to 59 €... There must be a difference, I think...

90% are PCIe 1x, some PCIe 4x...

If you dare and help me, I would appreciate it

Best regards

I've only installed a PCIe USB 3.0 card once and that was at work, and to be honest I didn't even notice if it performed well or not. What we can do is theorize a bit:

Transfer speeds according to PCI-Express version:

v1.x (2.5 GT/s):     250 MB/s (×1)     4 GB/s (×16) v2.x (5 GT/s):     500 MB/s (×1)     8 GB/s (×16) v3.x (8 GT/s):     985 MB/s (×1)     15.75 GB/s (×16) v4.0 (16 GT/s):     1969 MB/s (×1)     31.51 GB/s (×16) 

USB 3.0 transfer speed:

Bandwidth 600 MB/s

Then we have the info on the PCIe slots of your Workstation:

I imagine that you'll also have to take into account if you're going to use several USB 3.0 devices at the same time, and what seems no less important, the controller chip. Let me take a closer look at this.

For now, what I can say is that maybe you'd want the 4x so as not to limit yourself, but again, I don't know this firsthand and it's all just speculation.

Best regards!

I have no experience, but I would look if it has more than two ports that are pcie 4x because it might perform better, in the brand of the controller that is trustworthy, and then the cheapest

[Namiga]

Of course, and since there is a PCIe 4x slot in the PC, I will see if I can find any guarantees with that slot.

Thanks to both of you

This one I bought a couple of years ago. It gives me a transfer of 200 MB/s writing and 240 reading to a USB Sandisk Extreme 64 GB. All this from a Samsung 850 Pro SSD connected to a SATA II controller so it's not bad at all. At least when I bought it the chip to look for was the NEC (Renesas). I think for USB 3.0 you don't need to go to PCIe 4X.

Best regards.

@Magog thanks magog.
From what I'm reading, 95% of the cards are actually a hub.
If you have a 4-port card, each port will give you 25% of the transfer capacity... if you use them all, of course.
That's why I'm more interested in the pcie4x, as it would increase the total transfer...
I keep thinking about it

For example.... I just came across this youtube video...

The bad thing is the 140 turkeys it costs

I don't need that, but I also don't want to come up short in 2 days

I would try something like this for myself, it has a Renesas chip. If it doesn't perform with several USBs, I'll plug in another card with more ports, and if it doesn't work, you lose 11€, but if it does, you save 130€.

Thank you very much. Interesting, it has usb c...
