Powered USB Hub 3.0, atolla USB Hub with 4 USB 3.0 Data Ports and 1 USB Smart Charging Port, USB Splitter with Individual Power Switches and 5V/3A Power Adapter

connected to home assistant and plugged in my usbs and everything worked

Since the moment I have 2 Raspberry PI 4B's, I have been struggling booting from USB3 SSD or SATA HD drives as the Raspberry PI 4B is very power critical. I use ArgonOne cases for my PI's and when it powers up it also suffers a small spike in power consumption when spinning up the fan. I tried numerous powered USB3 hubs, but all of them had the problem of power feedback to the USB3 port of the Raspberry PI and it simply won't boot from external HD's.But now with this powered USB3 HUB, I can boot directly from a SSD drive and mount the other SATA HD drive without any problems !It is important though (at least for my config) that all the drives are connected to the HUB, and that the hub is connected at the LOWER USB3 port of the PI 4. The drives need to be 'on power' when the PI4 boots.Speeds I get with a standard SSD : between 250 - 350 MB/sec (depending on the linux distro, Ubuntu gives the highest throughput, 350 MB/sec, all other distros I tried peak up to 250-280 MB/sec)In the same HUB I also have a Seagate 1TB SATA HD, and the throughput stays stable around 120 MB/sec.I ordered two of these hubs, and they both perform fine on a PI 4B-4GB ('older' revision) and a PI 4B-8GB (Newer revision).I only tested for a week or so, with two external drives. But till now , it works 100%.If you have a Raspberry PI4 and are looking for a GOOD powered USB3 hub in order to connect SSD/SATA HD's, this is the only one I could find in almost 1,5 years.I wish I had bought this HUB earlier, would have saved me lots of time and frustrations!

I use this to connect my back up external hard drives to my PC and shut them down when not in use, but not have to pull plugs.It is very compact and very, very light weight. It won't sit flat on the desk as the connected cables easily lift it. I used a couple pieces of FunTak underneath to hold it down solidly to the desk - works perfectly! I now don't have to try and find somewhere to hold the hub while inserting or pulling out cables.While setting everything up, I inadvertently pressed one of the power buttons for more than a couple seconds while trying to hold the hub down (pre-FunTak) and plug in another USB cable. That turned off one of my hard drives while it was communicating with the PC. When I powered the hard drive up again, the drive did not show up on the PC. I powered up another drive connected through the hub and same result. I plugged the hard drives directly into the PC's USB port used for the hub and those didn't work either. AAAHHH! Did the hub just ruin my PC's USB 3.0 port? I plugged in my wireless mouse USB dongle to that port and that actually worked. Hmmm - my drives must be trashed!I did more checking and while 2 of my hard drives wouldn't work, one that I hadn't connected yet did when plugged directly into the PC. I was ready to return the Atolla hub as a piece of junk and thought I'd lost a couple hard drives and valuable backups because of it!As a last resort, I restarted the PC. Lo and behold everything worked again. It turned out that a USB software issue developed as a result of the hard drive disconnect. Never seen that before.I religiously use the "safely remove hardware and eject media" function before powering down the hard drives and, so far, I've had no problems since. The lesson here is - be careful with those power buttons!My phone doesn't register a "Fast" charge when connected to the power port, but seems to charge quickly. It does not communicate with the PC when plugged into the charging portThe blue power LED's are small and not at all overwhelming like some other devices I have that light up the room!My USB 3.0 data transfer rate is around 35 Mbps, which is about 10 times the speed of my USB 2.0 drives.In conclusion, the hub does what it is intended to do, but it is too light not to have some other means to hold it down on the desk

This wonderful little black box is a 4-port, POWERED, USB 3.0 Hub. With an extra Smart Charge port for charging your phone/tablet/device. The On/Off switches are very clicky and responsive. The Blue LED indicators for all 4 of the USB ports make it simple to know which ports are being used, and which ones are NOT. So, gone are the days of unplugging the wrong flash drive, causing the loss all your data or it being corrupted.Now I have used this thing daily for the past 3 almost 4 months now, and I have to say… I have ZERO complaints! That is very strange for me as I always seem to find something, anything wrong with pretty much everything I buy. I am a sort of nitpicker you could say.Now the USB ports provided by this Hub are USB 3.0 and NOT 3.1! This is important if you are after max data transfer speeds. Now the difference between the two, even as noticeable as it is, really will NOT make much of a difference to the average person. As the average person is not looking to transfer a 10GB piece of data in seconds… The average person is going to start the transfer and walk away. Then they will stay away for a minimum of 5 minutes, and 5 minutes is plenty of time to transfer data at 3.0 speeds. Remember 3.0 is an enormous upgrade from 2.0!!Now, about the charging port…. Hhhmmm, what can I say about it... It is NOT QC 3.0 compatible so for me, it doesn’t really have any use for it…. However, for someone who doesn’t care about charging speed, or does NOT have a quick charge compatible device then they will surely get good use out of it!Now one of the major selling points about this Hub is that it supplies its OWN POWER! Which means it can totally handle one of those external drives being plugged into it and used. Sure, there are tons of External drives out there that do NOT require an external power source at all, but there are still many, many that DO.So overall I would highly recommend this to anyone who finds themselves in need of extra 3.0 ports, OR they cannot reach the ones they already have.

Use it every day, no issues. USB charging on the side is a plus.

Works great, would buy again. Shipped quick too.
