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.

One of the worst products I have ever purchased. This device always disconnects from my PC for no apparent reason. Don't waste your time on junk like this.

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…

An old desktop I had with several hard drives in it that served as a file server gave out. I didn't want to have another dedicated endpoint to simply host hard drives over my home network so I decided to get this dock. I have no intention of using the cloning functionality so I cannot speak to the product in that regard. However, for providing access to my files on my drives, this devices works fine. I have 2 3.5 and 2 2.5 drives inserted into the dock and the dock is connected via USB 3.0 to my Dell monitor which itself is connected to my Mac Mini. At first I wanted a USB-C connection (or was thinking of getting an adapter), but the USB 3.0 connector worked fine for me since my monitor (which serves as a hub) had a USB 3.0 port anyways. Setup was fine, transfer speeds are on par with the standards used, and the drives, either 3.5 or 2.5 (and even then, the fatter and slimmer 2.5s), sit comfortably and securely. You can insert and remove drives with the dock still plugged in. One star is knocked off for the less than ideal build materials (just a hair above too plasticy) and the drive indicator lights being rather generic and bleed into one another. Overall a decent and quick solution for my drives, I can access my files locally with ease, or across my network through my Mac Mini.

well, its fast. But it goes offline then back online quite frequently.

Not a problem reading the drives. PC recognize it immediately.

Exactly as advertised. Great product.!

muy buen producto, llego perfecto todo bien funcionan perfecto con mi cpu

I bought this 4-bay SATA USB dock almost two years ago, and for a long time it behaved like a good little device. Plug it in, drop in drives, everything worked. Life was good. Then one day—poof—it stopped working. No warning. No drama. Just dead. I contacted support, hoping for help. Instead, I got a polite shrug and a 15% discount offer on a replacement. “Do I want to buy another one that might quit after two years?” Yeah… no thanks. Turns out the warranty is only one year, so repairing it was officially not their problem. That stung, especially since I have SATA-to-USB adapters that have been working happily for 5–10 years. Suddenly this “deal” didn’t feel like much of a deal at all. At this point, I had nothing to lose. So I became a hero. I peeled off the rubber feet, removed the screws (four for the case, five more for the motherboard), and opened it up like a treasure chest. Inside, I went hunting for the dreaded enemy… SMOOOOOO. Armed with my finest tool—the mighty TOOTHPICK (strong enough to poke, gentle enough not to destroy)—I carefully inspected and cleaned the board. On the bottom side, near a SATA power solder joint, I found suspicious smoo that looked like it might be causing a short. I cleaned between the solder contacts, reassembled the unit, and took a deep breath. I plugged it in. BOOTED NORMALLY. No error. No drama. I dropped in a few drives for testing, and—YES—it worked! The dock lives again! Honestly, thank goodness it was out of warranty, or I’d still be waiting weeks for shipping instead of fixing it myself in an afternoon. I’ve put it back into service, now running four 3.5" SATA drives at a normal load. I’m happy again… cautiously happy. Will it last forever? Time will tell. But for now, the adventure has a happy ending.

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.

The Bays are big, so the HD are loos, wiggle, with potential for data loss. Can NOT connect 3 at the same time (12 HD at once) (not enough power from MY USB ports). I still use it via Network Share, and it serves it purpose, just not the best. Oh, the holes are exposed to dust, would be better if they were backwards or covered by the flaps.

Simple et fonctionnel

When my iMac M3 (Sequoia 15.3) 'sleeps' the drives disconnect with the "Disk Not Ejected Properly" message. After purchasing the product I received an e-mail from MAIWO which (amongst many other things - all good), stated: << Constantly disconnect: If the drive indicators went out, please contact us to update firmware via Amazon Message. >> So I sent them a message via Amazon and in reply to their e-mail. If this works, I will keep the product - otherwise I will return it end-of-Feb. Otherwise it is fine so far - but the problem above is not tolerable for the long term.
