![]() ![]() The T5 works for USB3, but I believe the T7 gets speeds close to 800MB/s with USB3.1gen2, and newer, for just a little more $. ![]() They don't have the SATA SSD limitations (<600MB/s) as they are NVMe based. Some of the new, tiny portable SSD drives, like the Samsung T5 and T7 work really well for certain tasks. No USB PCI card that I'm aware of will allow booting, so you must plug it in to the USB2 ports front or back on the chassis, which are super slow. Most USB3 cables are fine for USB3.1gen2. BTW, specs for USB are all over the place, so run the BlackMagic Speed Test to get real world specs. ![]() On the other hand, if its a spinner, or almost anything else, USB3 is fine and there are adapters and adapter cables galore. It also comes with its own power supply to help keep all the gadgets you plug into it running. ![]() So, if your USB external device is a fast device like an SSD, you can double your speeds with a 3.1gen2 card. You also get three USB-A 3.0 ports, gigabit Ethernet, a combo headphone/mic jack, and an SD card reader. Both our units are typeA, to be more versatile. A friend has the 4 socket HiPoint with no sharing. The VisionTek USB 3.0 PCIe 4-Port Expansion Card lets you easily harness the power of your computers fast PCI Express card slots to add four SuperSpeed USB. That works well except each pair shares a port. Then I put a 4-port type-a USB 3.1 gen2 (<$100). When USB3 was fastest, I had a $60 4-port unit from Sonnet. Those are USB3.1 gen2 or newer, and they come in a variety of configurations with type A or Type C (USB-C), and port sharing except for the HiPoint unit which is best. If you need the faster speeds of USB3.1gen2, you can also get those cards which are <1,000MB/s. The best cards have an unshared USB port for each device. If you need USB3 speeds (<500MB/s) The choices are mostly 2-port and 4-port cards. I have some experience with several of the USB PCI cards for the cMPs. ![]()
