A hub USB 3.0 performance
Computers even latest have generally at your disposal a lot of USB 2.0 ports, but few in USB 3.0. With the increase in the number of devices comply with the latest standard, a hub or “multiplier of ports” USB 3.0 is essential, especially on laptops with few of these dedicated connectors (only 1 or 2).
The interest of USB 3.0 is able to manage devices to high performance requiring more power and flow rates. Accessible for less than 18 euros, here is a model of hub 4 ports proposed by Amazon under the Amazon Basics brand.
Like all products sold by the Seattle giant AmazonBasics, packaging “unpack without getting upset”, simplifies the unpacking and recycling. Here the container comes down to a United recyclable cardboard box containing:
- The 3.0 Hub 4 ports
- The mains 5Volts 2.5 has
- The instruction manual written in french, English, German, Italian and Spanish
Aesthetics: This device does not resemble a traditional hub generally more bulky. This one is even more light (230 g) and even more compact (8.9 x 3.8 x 1.5 cm). It can slip across and is intended for computers with a USB 3.0 port and the operating system Windows 8, Windows 7, Windows Vista, Windows XP, Windows 2000 and Mac OS X.
The use is comfortable despite the fact that there is no led to check if the hub is properly fed or connected to the power outlet.
First big disappointment: the supplied USB cable is not only too short (24 cm)but is mostly built into the hub. Good behaviour, it is impossible to change this cable: if it breaks, the hub will go in the trash. Because of this length limit, this hub is almost stuck to the USB ports placed in the rear of a central unit, so that a hub is rather intended to be placed on a desktop. Fortunately, the purchase of a USB 3.0 extension is possible and becomes almost indispensable. I personally opted for this excellent model AmazonBasics extension USB 3.0
Fortunately, the power cable attached to the power adapter to the hub is very long (about 1 m 50).
Speed: To enjoy the best of this hub, you must connect it to a free USB 3.0 port of a computer. It is retro compatible USB 2.0 and 1.1: older devices to these standards will work there.
Supported rates are 5 Gbps (USB 3.0), 480 Mbps (USB 2.0), 12 Mbps (USB 1.1 mode high speed) and 1.5 Mbps (USB 1.0 and 1.1 mode low speed). It does not support the standard USB 3.1 to 10 Gbps, set in August 2013 (the interface changes which would have made it impossible to backward compatibility).
What about the food?
We can use this hub without a power adapter when a few low-power devices are connected. However, as soon as the energy need is felt, the call of the block connected to the electrical outlet becomes mandatory.
When you plug in the AC adapter, the hub immediately password mode Auto mode power supply by bus without any disconnection of the connected devices.
A USB 2 port is powered at 500 my on 5V (2, 5W). The USB 3, allows on 5V 900mA (4, 5W). The transformer supplied with this hub Amazonbasics is too small: If you consider these 900mA by port, it would take until 3.6 altogether on 4 ports (0.9 x 4). However the adapter delivers up to 2.5 A. In normal use no problem will be found, but if you plug in 4 very consuming devices this may be felt by some micro-deconnexions.
I was able to successfully test the following devices (without power supply):
- 1key Bluetooth Asus : coupled to a Nexus 7 Tablet and a Nokia phone
- 1 key USB Kingston U3 2 GB
- 1 key USB Verbatim 32 GB Store ‘n’ Go
- 1 key USB Flash Corsair 8 GB
- 1key USB WIRELESS Belkin
- 1key USB WIFI Connect Sandisk 32 GB
but also (without power supply):
- 1case drive external 2.5 “Seagate Wireless STCK1000200 (USB 3.0)
- 1case drive external 2.5 “Inateck FEU3NS – 12.5 (USB 3.0)
The simultaneous connection to the hub of these 2 cases to the standard 3.0 requires connection to the sector to meet the rising power consumption.
Transfer devices are very good and in respect of a USB 3.0 connector: between 86 and 100 MB/s for medium-sized files (300 MB videos) and between 73 and 140Mo/sec for very large files (iso of 50 GB).
These performances are at the top for the Seagate box and are slightly inferior to that of Inateck, due to my choice of the hard drive inside (an old drive SATA II, I have 7 years). With a newer and faster hard drive (as a 7200Tpm), we should easily exceed the 120Mo/s.
Connected to the hub, built-in hard drive Seagate Wireless is at the top of its performance. We pass by a USB 3.0 of the tower or one of the 4 hub, the flow indicated by Windows are similar. The Hub is up to expectations.
Here is the benchmark of HD Tune on this hard drive placed on a port of the hub:
Logitech G930S wireless headset:
About the Logitech G930S wireless headset, it asked me a few problems.Indeed the key USB dongle is recognized is well managed if it is the one connected to the hub.
On the other hand, in the presence of other devices (USB keys and hard disks) on this hub, the led on the headset will Flash and in Windows, the device corresponding to the output its appears and disappears incessantly (stall).
The solution? Must remove all connected devices from the hub and plug the dongle G930S first, and then reconnect all of the other devices.
With this method, we can simultaneously operate the Logitech G930S headphones, lovers 2 hard drive USB 3.0 enclosures and a USB 2.0.
And the charging sector mode? (without connection to the PC)
This hub can properly recharge the battery of the G930S helmet.
Unfortunately with regard to a Nexus 7, the hub will not be replace charger. Indeed, connected to the hub, it displays “In charge” but the message disappears instantly. There is no other solution than to connect the hub to the computer to recharge.
In addition, according to the documentation, the hub of the American giant does not load devices requiring more than A 2.5.
The AmazonBasics USB3.0 hub is a reliable device that assumes its functions successfully with a total respect of flows. On the other hand I regret unable to recharge a Nexus Tablet and the length shortened by the integrated USB cable. Apart from that, this hub is a great investment (less than €18) If you want to up to 4 additional USB 3.0 ports.
