    • Cheap, but well built and perfect for instances where you need to use an External attachable drive.
Size: 2 BAY
I have to say, this is probably the most ingenious USB connectivity style external drive connector I've seen. I love how easy it is to install and use. It's not too big, so the size isn't an issue. It works great for the application I bought it for, but it gives me a whole plethora of ideas of how to use it long term. And the price is on par with other usb adapters to quickly hook up an drive via USB without a case. I love it. ... show more

Review Image by Ron Ron
I did not know how fast USB 3 was until I bought this Sabrent dual bay docking station. The Sabrent worked flawlessly in every respect. I should have bought this docking station long ago. I have been using USB2 for a long time, I never knew what I was missing. The reviews were right. This station is the best...Thank you Sabrent for bringing me into the future. A great product at a great price. Only one tiny flaw. My docking station is under a shelf and I cannot see the A and B on the back. A trip to hobby lobby fixed that issue for me. A little bit of front lettering.....Take notice Sabrent. ... show more

    • SIMPLE AND EFFECTIVE DEVICE
Size: 2 BAY
Good product. Does what it says it will. Minimal amount of setup and easy to use. Basic, not fancy, but functional. I was pleased to be able to get some data back from old drives, although not all of them worked (which isn't this device's fault, obviously).

    • Good Value For The Money Fan, Clone & 2 Types of Drives
Size: 4 BAY
Update: 10-25-2023 I formatted my one of the drives in my new Sabrent Docking system and the speed more than doubled with the exact same file I used yesterday. Yesterday I was getting max 50MB/s on a 1.6TB File Today I am getting 164MB/s on the same 1.6TB File Transfer both NTSF. So, great improvement. Excellent Indeed. 10-24-2023 I got this because I have 4 OLD HDD's THAT I still want to use to back things up to. The reasons I picked this were 1. Low Cost 2. Has a Fan so no overheating, 3. Can fit both HDD 3.5 Inch and SDD 2.5 inch Hard Drives 4. It also has a cloning option built in. It was very simple to install. Literally just plug and play. My New PC recognized the Drives Straight Away. They simply act as a large volume flash drive for those wondering. I have a 2 TB, 8 TB, 4 TB and 6 TB My New computer uses the latest technology and was rather spendy so I didn't want to purchase any more hard drives just to fit inside the computer. So, for $88 plus tax it was a good deal. I am copying all of my documents, photos and personal videos about 1.6TB over from one of the HDD to another HDD in the Sabrent Dock and I am getting about 50 MB/s. Rather slow but I didn't format the old drive prior to the copy and I regret that now. I think I would have gotten better speeds had I reformatted prior to the copy. Overall I am very pleased with the Dock and Highly recommend it for anyone so long and you don't have a dog or say children that may accidentally knock it over. The drives themselves won't take much of a jostle but the dock although plastic works very well and as intended. CHEERS! ... show more

    • A good way to temporarily connect SATA drives to your computer
Size: 2 BAY
I regularly have a need to temporarily connect SATA HDDs or SSDs to my computer, either to pull off some data, to wipe them clean or to run a "burn-in" test on a new HDD. In the past I used a powered SATA to USB adapter and put the bare drive onto my table (or rather onto a mat on my table to minimize vibrations). This unit is the more sophisticated version of such an adapter and makes my desk look less like a lab and more like an office. The unit provides two SATA connectors to connect two drives in parallel and even the option to perform an offline copy from one drive to another (which I did not test). It comes with a manual printed in color on high-quality paper, however the only important info I took from there is that the drive(s) should be inserted BEFORE turning on the unit. That means that the unit apparently does not have hot-plugging/hot-swapping ability (or at least it isn't officially supported). The unit has a power switch and a clear plastic cover to protect the device from dust, while not in use. Unfortunately though that plastic cover has no cut-outs for the connected power and usb cable, so it looks a little slapdash on my desk. The unit also has some padded feet, however these are very thin and do no prevent vibrations from HDDs to transmit to your desk. As a consequence I will be buying some thicker adhesive rubber feet to mitigate this. After using the unit for a few days I can say that so far it has been very reliable. I used it to do read and write tests on two HDDs (4TB and 14TB) and it has performed well. I have connected the unit to a USB 3.1 gen 1 (5Gb/s) port on my computer, which is the maximum connection speed that this unit can operate in (so no point plugging it into a 10Gb/s port). However for HDDs the performance will be dictated by speed that the HDD can provide anyway. During a linear read and write test, the speed was as high as 260 MB/s for some parts of my 14TB HDD (a WD Red Pro), but - as expected - lower in other parts of the disk). For an old 4TB disk the read and write speed was 50MB/S, so this unit can definitely keep up with current HDDs. However in principle the 5Gb/s transfer speed on the USB 3.0 interface of the unit is 18% lower than what SATA III allows for (6Gb/s), though these are theoretical speeds. To test the limits of the transfer rate, I also tested this with a 2TB Crucial MX500 2.5" SSD, the highest transfer speed on a sequential read test was about 405 MB/s. CrystalDiskMark 8 showed max. sequential read speeds of 460 MB/s for reading 5 1GiB Blocks. So the interface is plenty fast with one drive installed, at least for my needs. However when running two WD Red Pro 20TB HDDs in parallel and running a sequential write on both at the same time, the data transfer speed dropped to 160 MB/s at the beginning of the disk, then slowly increased to ca. 190 MB/s about two thirds through and then dropped toward 125 MB/s at the end of the disk. So there is definitely some overhead, when using two drives at the same time. All in all I am very pleased with this unit so far. I would deduct half a star for the clunky cover and the thin feet, but at 4.5 stars a round-up to 5 stars seems more fair than a round-down to 4 stars. I have some more HDD burn-in testing to do in the coming days, and I will update this review, if my view on this unit materially changes. ... show more

    • Solid product for pulling data
Size: 2 BAY
This worked simply and well, fully plug-and-play. No issues. I was only using it to pull data off an old drive.
