SABRENT 4 bay hard drive docking station, SSD HDD 2.5 3.5 inch SATA case dock, external SSD enclosure + power adapter, offline cloning, LED indicator, tool-free, USB cables included (DS-U3B4)

Makes backing up systems extremely easy and you can use hard drives like disk drives and hot swap while the computer is on. Speed is good and device is sturdy and well made. Works plug and play on Windows and Linux (haven’t tried mac but sure it’d work) and can be used as a boot drive to quickly recover from a drive crash or corrupted system. Don’t know how I lived without it. Looks like a toaster 😁 paired with a RaspberryPi, you can make an extremely fast, feature rich and reliable NAS/Cloud server/time machine network backup for 1/4 the price of a ready made NAS and 10x the features. Works with 3.5” and 2.5” HDD and SSD. With HDDs, the disks never completely spin down which makes accessing files quicker but does create some noise. Also the drives can get hot, I have a square case fan powered by my RaspberryPi 5v GPIO pins to keep it cool.

They work great with laptop and desktop hard drives. I have found a minor thing if you have two desktop hard drives in they can lean abit they stay connected but on can lean so I made a little device to keep them apart and upright. They are easy to use and set up plus hot swop. They are worth the money. The power adapter is not bad in length.

Great product for the simple needs of most home users. Delivered the next day, and worked straight out of the box. Does exactly what I need which is to more easily access a mix of existing 3.5 and 2.5 inch discs for backup and for mirrored archive.Looking at some of the other reviews: it is delivered with a UK plug so don’t worry about that. Yes you hear the 3.5 inch disks spinning but you always do so and I don’t need them on all the time. And quality is fine for day to day home office use.Some pointers: No this is not a RAID device but it does not claim to be. Like me you will probably have to use Disk Manager to assign a drive letter before your PC will recognise the drives - easy done. This is not as ‘hot drive removal’ as they claim - remove a drive and they all uncounted so you have to switch off and on again! The PC sees this as a series of removable disks so Windows does not allow you to span or stripe two disks as one volume.Great product.

Bought to replace a USB2 single dock, which dislikes the USB-C/TB4 in my laptop. Works fine, and the cloning in the dock - Win10 OS SSD drive to a smaller SSD - was completely painless and just worked. No slower than doing it the hard way with Acronis, no boot or other issues.

Used as both a docker and is great at hot swapping both platter drives and SSD's - transfer rate of 480gb around 36MB / secThe clone function works perfectly, source in upper slot, destination in lower. Unplug unit from USB and hit the button. If the destination is larger than source, just expand in Disk Management to utilise the unused space once cloning complete.Well worth the money for the functionality and does not tie up the host PC when cloning.Recommended

I had been using desktop machines for many years and has simply put my old disks into the machine so that I could use the old disks. Having now changed to a laptop that option was no longer possible, but using this product I can now continue to use my old disks for storage.Good product!

Very light-duty, but may be acceptable and convenient to keep a couple drives together and store a media library or other replaceable data. TV/Console/Home Theatre, etc.Biggest problem: Some 3.5" drive combinations do not initialise (when paired); maybe inrush current too high for the included power adapter.I ordered 2x of these after being very satisfied with the Sabrent USB 3 to sata 2.5" (UASP) cable. However, the units are a hollow shell of molded ABS plastic. So light and resonant that 1/4 of the weight of the unit (~95g) is a weigh-down chunk of steel internally fastened to the base of the unit.It's now obviously a rebadged low-end run of the mill unit. There is no drive dampening whatsoever. The connectors bear the weight and vibration of the drives. All the physical guiding to insert a drive is the actual flimsy flaps, which means damaging the sata connections on the unit or the drives will only be a matter of time (crooked insertion, etc). The drives can also become trapped in the flap door on the way out, easily ripping one of the flaps like another reviewer found out.Electronics are cheap but not too bad. The controller (ASMedia ASM1156) works well enough, but may not be considered 'reliable' in data storage terms.Overall I don't recommend and would not put any critical data through these. Some may think it's worth ~£20, but I dont think it's worth the risk.

The media could not be loaded. I had to 2-bay version of this which my only complaint was the lack of bays. As my requirements have changed, I have moved to the 4-bay version. My first impression is that HDDs are not held nearly as securely as the 2-bay model. You plug them in and they literally sag to the side and flop about. I'm a little concerned about this. I'm considering gluing something to the bay doors that will pin the drives in place as the doors are opened.Aside from this, I plugged this into my Mac and it immediately detected the drive and the connect quickly. It's just the floppy drives that give me cause for concern.If it breaks, or I lose any data, rest assured I will be back here in a flash to lower this rating to 1-star.
