MAIWO 4 Bay Hard Drive Docking Station Cloner for 2.5 3.5 Inch SATA HDD SSD, USB 3.0 5Gbps Speed with UASP, 96TB Capacity, External HDD Duplicator Reader

I don't recall drive docks being this responsive. I didn't know what to write because this thing just works as it should but I think I've had some goofy ones recently and this one doesn't give me a hassle. If you need to just get something that's not broken, and not want to spend effort on searching for something that should just be a simple purchase, well this is that, your simple purchase, it just works, doesn't get in the way. I got this one primarily because it didn't give me the impression that it would clone (overwriting) one of my other drives, if I sneezed near it. I almost forgot to mention , this isn't the first one of its brand that I purchased. After testing it for awhile I got another one, this is the other one.

Works as advertised. No connectivity issues

I have four internal hds and two external. This works perfectly for the internals. Be sure to use the right power supply with it. I mixed mine up and the drives kept dying. Anyway…

This product is mere garbage. For starters, the performance is not as advertised; at best, it performs at 20%~40% of its advertised speed ratings. Not the USB port, not the USB cable, and not the operating system, as I've tried many different ones on different computers and on 2 different operating systems. The culprit is the hardware on this crappy device! Additionally, after a few minutes of heavy writing to the connected drives, it will lose connection, likely due to bad hardware it was built with, which will result in errors such as the ones on the attached image. The UASP driver it has is beyond crap too. While computers will recognize the drives on this device as standard block devices and seem to operate correctly, they most certainly will not. Using this for serious things will more than likely end up corrupting your data and if not, it will for sure give you a bad time. Lesson learned: just spend a few extra bucks for certainty over being cheap and getting really crappy hardware such as this device. This is being returned as of this posting.

My home pc failed hard and needed replacement. Decided to move to the Apple ecosystem. However I have a plethora of drives used for storage. Wanted a way to "pool" the drives without purchasing a NAS etc. Came across this unit which fits the bill. I have an older Black X single HDD dock but found USB1 is simply too slow for the amount of data to be transferred etc. Item received the next day and inserted four drives however for some odd reason only three of them would be read by the OS as properly formatted regardless if I moved the drives around. I'm using the latest version of Sonoma of MacOs via Mac M2 Studio. After some attempts I decided to return this and scheduled a pickup for rma. However that same evening I decided to format each drive independently on an old windows 7 netbook and then attempted to get all four drives formatted and read by MacOs. To my surprise it worked. I then proceeded to set up a Raid0 across all four with a fifth drive as a back up. I cancelled my return and thus far it's been rock solid. Note, this dock is not UASP enabled so forget about that extra speed boost. This dock with all drives populated and with some heavy usage will generate some heat. I do believe this is due to the drives themselves even though they are green drives. For the price and its function it fits the bill. Recommend! I have not tested the cloning but it's nice knowing the option exists.
