Wavlink WL-ST334U USB 3.0 to SATA Dual Bay Hard Drive Docking Station for 2.5" 3.5" SATA HDD/SSD Storage Dock 2x 8TB Hard Drive Enclosure, 5Gbps Data Transfer, UASP, Offline Clone / Duplicator & One Button Backup

Pros: allows you to clone a drive without a PC

Cons: 75% Led light stuck on

Overall Review: I had issues with my product but Wavlink promptly reached out to me to resolve the issue. They were very reasonable and we came to a resolution that worked for everyone. Excellent service

Pros: Easy and fast cloning of a drive when you need to go a larger capacity drive, no need for a computer. It is inexpensive enough, you want to have one on the shelf for when you need it.

Cons: Instructions are a bit sparse, but if I can figure out how to do the cloning, you should be able to as well. The instructions don't mention this, but if your target drive is a larger capacity than the source drive, you will need to resize the resulting volume to utilize the extra space.

Overall Review: I cloned my wife's older 32Gb SSD to a much larger drive. The cloning took 5 minutes, I guess, 15 minutes total from the time I opened the case till I closed it up again. It booted up without any problem, except it only showed the 32Gb of the original drive. Duh! It is a clone, what was I expecting? A quick search pointed me in the right direction: go into the OS under storage and resize the volume to utilize the entire drive.

Pros: -Dual Docks means having either two mounted drives AND you can duplicate a drive without the use of a PC. -USB 3.0 speeds are great, especially when you are transferring large amounts of data.

Cons: When mounting a single drive and then adding a second drive, windows unmounts the single before mounting both. Not really a big issue, just a minor annoyance.

Pros: Machine worked very well. I've only used the offline cloning feature and there was nothing to it. Took about two hours to clone a 1TB HDD. Had no problems with the clone once I installed it in my laptop. Even if I never use it again it was well worth the money.

Cons: none

Overall Review: Documentation states the target drive has to be larger (capacity) than the source drive.But i'm a gambling man and tried to clone a 1TB HDD to a 1TB HDD and it was successful, no issues at all. Maybe I got lucky so try that at your own risk.

Pros: none

Cons: This is supposed to be able to clone hard drives. Tried several times with different source and target drives. Never worked. Tried a new hard drive that should work, it still would not clone. I tested the new drive and copied some files to it, so I am sure it was OK. - Don't buy this product. No customer service no response to emails in 8 days.

Pros: It looks pretty and holds 2 drives

Cons: Loses connection and never actually allows me to transfer anything

Pros: Main purchase decision... I purchased this Wavlink Dual Bay HD Dock so that I could have my older Sata 3.5" HD's securely erased before I recycled them. This dock is perfect for my Sata 3.5" HD security wipe requirements. I have my own security wipe program that I purchased for this task. My old WD and Seagate HD's were were making noise in my computer desktop. So, I replaced them with new ones. This dock easily accomodated my old WD and Seagate 3.5" Sata HD's. They fit securely when inserted gently in the Sata connector inside the dock. The dock has a blinking Read/Write LED that shows the activity of the HD's and a Power LED for the dock to show when it is switched on. Please note that it is easy to accidentally press the on/off switch while carrying the dock from one location to another. I always make sure that the power switch is in the off position when I rest the dock down on my work surface. Then I can safely insert the HD into the dock, connect the included USB 3.0 cable to the dock, and plug in the power supply that came with the dock. I then turn on the docks power switch. I then attach the other end of the USB 3.0 cable that is coming from the dock to my PC and run the security wipe program. Other thoughts... I have only used one dock bay at a time since you can only run the security wipe program once per hard drive. I haven't even taken advantage of the dual dock bays use of two HD's inserted at the same time yet. I can't comment on that yet. However, I bought this dual dock considering I can use it for other purposes in the future. I have carefully compared this docks features to that of other docks in the same price range. I did not want to spend that much money on a dock for my occasional use. Final thoughts... I am greatly satisfied with this dual dock. I would highly recommend it to a friend if asked for my opinion.

Cons: None at this point.

Overall Review: I'll update this review if it stops working for no good reason.

Pros: plug in play great transfer speeds

Cons: none
