I needed a back up hard drive and I wanted one that didn't need a separate power supply for when I travel. This one works as advertised. Comes with both Firewire and USB cables and has a nice light on it to tell you it's on. Formatting for Apple OS was a breeze.
I am using this item as a replacement for the hard drive on my 27" iMac 11,1 (late 2009). It was easy to connect, format, and load (using the iMac's migration assistant). The instructions were clear and precise, the drive and enclosure appear well made, and the price is just right. It is no wonder that this item has been highly rated by MacWorld and others.
I now have 3 owc portable harddrives. They work well out of the box. OWC is very quick to fill the order. I'll try to remember to write another updated review after a year or so after I have a chance to experience their durability and reliability.
This SSD was purchased to store video for surveillance system. It is stupid fast and the entire connection process was a breeze. Being SSD no noise and the light on it gives my office a nice blue hue with the lights out. Could not be more satisfied with this drive...
I have purchased several of these drive enclosures over the years and ease of set up and portable convenience can not be beat. I carry one with me at all times to do a quick backup of a client or friend's data as a safety measure. They come with a handy carrying case and necessary cables. Also, BUS powered and so convenient.
This product is perfect for what it does, but really I should have waited until the thunderbolt version is available (whenever that will be). Even Firewire is not really fast enough for the purposes I wanted the case for (replacing the boot disk on an old iMac using an SSD drive I already have).
Also, it confused me when I received it with only one cable - the other cable was hidden inside the carry case which took me a while to find!
Cons: performance compared to thunderbolt
No, I would not recommend this to a friend.

I had to remove and re-install a bunch of drives into this case because I was using it to recover data from a couple of failing drives as well as for backing up (cloning) my main laptop drive and finally installing a drive that I will use permanently in this enclosure for backup. I must have removed and installed a drive from the enclosure about twenty times over a period of a week or so. My analysis? This is a very high quality enclosure at a great price that I would recommend to anyone. It just works and that's what I expected from OWC. Great product.
It's nice to have usb 3 and firewire. Putting it together took longer than expected because the metal thing inside needed to fit in the square hold of the plastic case. In order for me to get it right I had to not put two screws in but it still was secure. So on the side there are two screws and one screw can slide a little. I kept that one in and didn't use the other one.
I have used these cases several times to replace hard drive enclosures with failed bridge sets, where the drive itself is still good. In the latest instance, I needed to replace a Western Digital My Passport Studio enclosure - because WD offers no replacement cases for their drives. OWC provides a wide selection of connectivity options for their On-The-Go cases; I was able to actually upgrade from the FireWire 800/mini USB 2 WD case to a FireWire 800/USB 3 OWC case. While these cases are not inexpensive, the enclosures are solid and have an improved design that has an exposed heat-sink on the bottom of the case. Assembly is a bit tedious, with three sets of four screws and one set of two screws. But it provides an alternative to throwing away a perfectly good hard drive. And, if the drive eventually fails - as they all do - you can pop in a new drive without paying for yet another enclosure.
In addition, the On-The-Go enclosures can use a power adaptor if for any reason the drive won't mount on bus power alone. OWC offers power adaptors for a variety of drives and devices. I've purchased a number of these as well - as I did for this enclosure - see below.
I purchased one of these and found it to be an excellent portable package. It is much better than the cheep portable products I bought which failed and the drive could not be replaced. It is easy to use and carry when I travel. I like it so much that I bought one for my daughter and one for a friend.
Pros: Quality, Durability, easy to change hdd if needed
I bought one to use as backup for my MacBook Pro. It was so easy to use that I quickly purchased a second one so that I can alternate (I like to switch out weekly and keep one safely stashed elsewhere). I know just enough about computers and technology to be dangerous, but this was truly simple to use. It takes a little time to open Time Machine preferences and select the disk when I switch them out, but for me it is worth the peace of mind (real or imagined). I pretty much plug it in and ignore it until I switch, I don't even notice it doing its thing in the background. A nice case holds the unit and cable. I bought mine back in April and have had no problems.
