5 out of 5 eggsAn affordable laptop backup solution

Pros: It works at a decent price. It has an LED indicator.

Cons: Of course there are faster solutions.

Other Thoughts: Speed is important. However, incremental backups usually don't take long after the first run. Therefore it just wasn't worth paying extra to go faster.

I was surprised that the hard drive went in at a slight angle. This is necessary to get over the lip of the enclosure. I have installed and removed two different hard drives multiple times, and the enclosure is still working.

I am very happy with this enclosure and plan on buying a second one.

5 out of 5 eggsExcellent Value

Pros: Low price, easy to install HDD, USB 3.0, fast, good looks.

Cons: Included USB cable could be longer, but it gets the job done.

Other Thoughts: Great little enclosure at an excellent price. Fast transfer speeds and easy to install HDD's.

5 out of 5 eggsAwesome USB 3 speeds and USB 2, great price

Pros: Needs only a single screw to lock everything in place... Better build quality than others dobule the price.... Works on all my computers using USB 3.0 and 2.0 ports. Comes with rubber feet that prevent it from sliding off my Bluray player. With my Seagate 500GB 7200 RPM drive, im toping out at 100 MB/sec on a USB 3 port, and a 35MB/sec on a USB 2.0 port

Cons: None, i wasted money on horribly built Masscool and defective UHB-2233 instead of this first..

Other Thoughts: I have been looking for a good quality, low cost enclosure for a 640 GB Hard drive i replaced out of my HP laptop.. This is a great enclosure for any extra 2.5in sata hard drive you might have around or for a external junk drive. At $ 16, this was a steal and is more reliable than the high rated masscool USB 3.0 external enclosure. Rather than RMA, i spend the money on this enclosure and I am impressed. The Green LED is not too bright, and comes with a nice full size dual male USB 3.0 - micro B USB 3.0 cable. Tested with a Seagate 500GB 7200 RPM, and Hitachi 640 GB 5400Rpm Drives

5 out of 5 eggsSmall, sleek, works great

Pros: Works great, have used to clone HD's and SSD's with a bunch of different laptops and drives. No problems. Works with Macs too.

Cons: Could be cheaper I guess?

Other Thoughts: All my externals are USB 3.0 now. So much faster.

5 out of 5 eggsGreat value

Pros: I got this enclosure for a lot less than other ones on newegg. Fit and finish looks good and it works with USB 3.0 and 2.0. Speeds on 3.0 are much faster than 2.0 and very close to a direct sata connection (at least for a HDD...haven't put an SSD in this yet..)

Cons: Cord is very short. I contemplated giving this 4 stars because of the cable length, but couldn't bring myself to, since the product works well. The cable is just over 1.5 feet. It does feel a little cheap due to being plastic.

Other Thoughts: I had a CoolMax enclosure that died on me. Fortunately I was able to return that one through newegg. This one has been great so far!

5 out of 5 eggsWorks great price is right

Pros: This thing is fast and cheap. It's easy to access too, one phillips screw is all it took. Works with my Airport Extreme via USB 2.0 and my new MacBook Pro with USB 3.0.

Cons: None that I can think of, wish it was made out of shiny aluminum like my other Mac stuff.

1 out of 5 eggsFreezes randomly

Pros: None

Cons: Freezes randomly
Overheats a lot

Other Thoughts: The sata to usb3.0 converter chip overheats like hell during operations. For unknown reasons (overheating or power-saving?) it freezes every 5 min or so, which will crash your file browser and even the whole system. I'd recommend the MASSCOOL UHB-2233 Aluminum 2.5" Black USB 3.0 External Enclosure instead of this product.

3 out of 5 eggsAdequate

Pros: Works. Very simple. Single cable hookup for USB 3.0 and power.

Cons: Lightweight plastic, looks like it would be easy to break if you dropped it accidentally. Installing the SATA drive - it has a small PCB at the business end of the enclosure. it looks like you should just be able to slide the drive in at a slight angle and it will fall into place once connected. I got it about a quarter of the way on and decided that it was a bad idea, there's no flex in the PCB or the mount and I figured if I applied pressure I'd break the PCB, the HDD or the snaps holding the PCB down. Bad design.

Other Thoughts: I had to remove the PCB very carefully by levering the snaps open, then install it on the HDD and carefully snap it back in place with the HDD attached. Works, but there's potential for things to go wrong no matter what.

2 out of 5 eggsWhen it works, it WORKS!

Pros: Easy to install and hardware seems nice. Drive doesn't move around at all in the enclosure. Also, stays very quiet. USB 3.0 speeds are pretty fast with 5400RPM drive (40-50MB/s sustained)

Cons: I used this case to house my old data drive after being replaced with a bigger drive. While transferring data too it, it had to be monitored, as it would quit after a couple of minutes of transferring files! Also, the cable that came with the case was terrible! If you bump it ever so slightly, it would disconnect from the computer long enough to stop your transfers! Definitely couldn't watch movies off of it. Replaced it with the cable from my good SeaGate GoFlex and it works for longer, but still cuts out after 5 minutes!

Other Thoughts: If I wasn't in Afghanistan, I would've returned it for another case. Unfortunately, it's just not feasible here. I will be replacing it soon for sure!
