Today, a little test: a 3.0 USB hub. DLink is offering this product, the DUB-1340, which can connect four devices on a single USB 3.0 connector. Built around a VIA chipset, it overcomes a defect of NEC controller found on most motherboards, the number of connectors is limited to two. Not much to say, a USB hub is a USB hub.
It measures 72.4 x 97.9 x 20.2 mm and offers four-port USB 3.0 Type A female A USB Micro B type female can use any USB 3.0 in this format. An AC adapter is provided for each connector that can provide 900 mA USB 3.0 (and 500 mA with devices to older standards). The hub itself is "glossy", which is fashionable but not necessarily practical.
Small defect quite common, the USB ports are very close to each other, which may cause problems with USB sticks a little wide. For testing, we used a USB 3.0 Seagate GoFlex a Crucial C300 and a PCI-Express USB 3.0 NEC chipset based placed in a PCI-Express 16x. To begin, we examined whether the USB 3.0 hub had an impact on transfers.
As seen, the values do not move very little. Second test, we conducted the same test performance in the background with a copy being between a Velociraptor (SATA) and a Raptor plugged into the USB 3.0 in a second box. As shown, the hub has an impact on the performance and go through it limits the flow.
Still remember that USB 3.0 chips are generally limited by the connection to the system: if each port is in theory 5 gigabits / s (500MB / s in practice), the link PCI-Express controller current limit to 500 MB / s in total. The product is effective and the performance loss inherent in the technology is low.
Small flat on the connectors, too close, but it is a defect common in USB hubs. In practice, this hub is good for people who need more than two USB 3.0, which is at present a rather rare, or who want to bring the connectivity of the office. Indeed, the current USB 3.0 connectors are placed in the lower boxes and connectors in the front are rare.
This is a good product (sold about 50 €), which suffers from a major flaw: a very limited interest now.
