... the sata interface is flimsy and got bent very easily after a few connections
930242
The power adapter plug in for the power plug going to the end of the sata interface is flimsy and got bent very easily after a few connections!  No problem I fixed it with some used desktop parts.  Man these solder crimp on connectors are super!  Otherwise,  it worked like a charm!  Good is better instructions,  still a great bargain!

Update:

After several months in service, the drive regularly loses connection. After some trial and error, I determined it is not the drive nor the USB3 cable. It is the USB3 port on the back of the case. Move the cable even a tiny bit, and it will lose connection. Sometimes it loses connection without moving the cable. I think there is a bad solder connection on the adapter board.

I can no longer recommend this case.

Original review:

I bought a new Lenovo laptop (Y580), which came with a 500GB had drive. I swapped out that drive with a Samsung 256GB SSD for ultimate performance. The 500GB drive is perfectly fine for external storage. This Coolmax enclosure converted my internal hard drive into an external drive. The USB 3.0 interface is wicked fast for an external drive.

After soldering one of these things together I tried to plug a USB cable into it and the USB pins bent.

Right now it does what it needs to do, I can't comment on exactly how long it will last, but hopefully I won't have to find out it stopped working.  Keep in mind that it only has 2 sata connectors, so if you have multiple drives you will need molex to sata converters.

Its breaking after 3 months and only 2 times of being unplugged and replugged. It could be due to my MSI board's s***ty placement of the SATA input s***e, right in the middle of all chord routing spots...... but needless to say its kinda fickle and you have to be gentle. Works pretty well, I enjoyed the angle on one end.

Great cheap option for an extra 2 SATA ports but there is one problem. Never disconnect the SATA cables after they are plugged into the card.  Any SATA cable will strip the surrounding plastic connectors on the card regardless of how careful you are when disconnecting. Thankfully, I only needed a single SATA expansion for my setup so I can live with this card and it's single functional connector but for anyone looking for connectors that are actually durable, look elsewhere.

This worked well for quick and easy data transfers. It's dead-simple, just pop in a 2.5" SATA disk and you're good to go. Screwing in the slide-in tray was a chore, as the threads weren't milled to work with the provided screws.

After so many inserts and removals of the USB cable, the USB port on the device became loose and often would power-off the drive as no contact was being made between the port and the cable. I had to replace the enclosure due to this flaw.

A side note: most people wonder why there's another (smaller) cable hanging off the other end of the USB cable. The smaller cable is to provide additional power to the drive. The main cable provides power and also is used as a means to transfer data to and from the drive. You should use the little dongle so you provide ample power to your drive, though I've frequently used only the main USB connector with no problem.

Work well enough.  I've used this to recover drives when no other interface would work.  You can never have too many oddball drive interfaces laying around.  The ATX to SATA power cable provided with this is terrible though.  The pins are literally falling out of it and it's never been used.

Connection to Micro USB 3.0 port on back of enclosure was a near-immediate failure point.

First, the bad (so you know right away): As several other reviews have mentioned in various locations, don't count on the eSATA connection working for long. It worked fine for the first few months (I used it just once a week at most to backup my desktop drives). Then, it started working only inconsistently and I had to use the MUCH slower USB 2 connection. Now, the eSATA connection has not worked for a long time. On the good side, it worked very speedily when the eSATA connection on the drive was functional and I haven't had any complaints about the drive itself. It's just I would have bought a different and even pricier setup so that I could have used the eSATA interface. I wouldn't recommend this drive if you want to use the eSATA connection on the drive.

This works great. I used it to hook up SATA and IDE CD, DVDR, and hard drives to my laptop and successfully read data from all of them. Build quality could be better, as the data adapter was put together slightly crooked, and there were stringy glue remnants all over everything. It also has a funny chemical odor that makes me want to wash my hands every time after handling the parts. But it does what it's supposed to do.

It broke down in less than 3 weeks. As Im currently overseas, it was more expensive to send it to California for the warranty than how much it cost me...soooo I fix it by swapping the USB port with a cheap 3.0 enclosure. I wasn't happy about all the requerimientos to send it back for warranty

It's OK.  The slim optical drive option turned out to be inferior to a normal SATA drive (not this thing's fault, but once I gave that up this becomes useless).  Had a hard time with installed hard drives, some would not boot and I couldn't get hotswap to work properly.  The USB ports seemed to work ok.

This fits a very particular need.

Good thing it didn't cost much because it looks like it will be a waste of money. The SATA cable and the power Y cord are very cheap. When I was hooking up the power connections, wires and pins were falling out of the back of the larger plug. I got those both hooked up and the orange and green lights on the device were both lit up so I know I had power to both the device and the IDE drive. I installed it, powered up the computer and and the new drive was not found. I opened the computer case and found that the SATA cable had come apart. Part of the plug was still in the device and the loose end had the copper connections sticking out. Luckily, I had a spare SATA cable of better quality.
So now it's hooked up. Very difficult because the device it too long and the connections stick out the end making it longer. This was a second hard drive, not my main drive with Windows 7 on it. Now the computer would not boot. I did all kind of checks with my recovery disks and through the BIOS. Nothing worked and I wasted several hours. I finally pulled the SATA cord from the mother board and plugged it in a different SATA connection. The computer booted just once and the IDE drive wasn't showing. I carefully opened the case and made sure all the connections to the device were still solid. They were.
While I was looking and thinking, the computer decided to shut down and then again wouldn't boot. I took out the converter device and all the associate wires and removed the drive. NOW my computer turns on and works just fine again. If you buy one of these anyway, buy a new SATA cable with it and get one with a right angle bend on one end. It will save some space and keep the cable from being so bent when you try to install the device.
I have just one other idea (before I throw this thing in the trash). The IDE drive I am trying to use has no jumper on it. It worked fine in my old computer (with IDE connections on the mother board) with no jumpers, and it works now if I hook it up to my computer via a USB cable. I would THINK it would work with the converter with no jumpers, especially since the instructions don't specify any jumper requirements when using an IDE drive on a SATA mother board.
...and before you ask or wonder, yes, I had the SATA cable plugged into the correct connection on the device.

I love how this case looks. I don't love the internal drive bays. They're flimsy and they don't do a great job holding your drives steady. Just plugging or unplugging the SATA cable will pull the plastic rails out of alignment. Also, the drive bays' position in the case means the power and SATA cables are a tight fit under the side panel.

Pros: The PCI and power connector fit the hard drive well.

Cons: Bought this item and was going to use it to make an internal hard drive an external data drive.  The front plate that has the connection housing to connect the power and PCI is flimsy plastic.  The plastic holding the circuitboard broke so it doesnt stay on.  The front plate uses two tiny plastic sleeves to cover the HDD and keep the plate in place.  Those snapped right off!  The power cable is faulty as you have to hold the power cable where it connects to the adapter in a certain way to get the power to work.

Other thoughts.  don't skimp on computer parts.  go with companies who have built these types of devices for a while.

This hooked up to the drive I was trying to work on but it kept causing write failure messages while trying to use it. I just bought it because it was cheap and I did not want to spend forty bucks on an external HD enclosure for a one-time repair but that is what I ended up doing anyway. Maybe this adapter would work alright in a static situation. You get what you pay for.
