Pros: light weight aluminum, works with IDE and SATA drives, does not require tools to change or install hard drive
Cons: Other than requiring a brick since 3.5" drive require that much power, not much. The included 3' USB may be short for some uses, but it can easily be changed or extended with cheap cables--standard USB cable.
Pros: Supports both SATA and IDE. Thumb screws make assembly very easy. One of the reviews says there is no way to secure the drive, but actually there is, 4 slots on the back and 4 thumb screws, again very easy. I bought this to use on my work bench to hook up customer's hard drives for service, having support for both interfaces and being able to remove top and sides makes it perfect for this. AC adapter uses standard cable. Good price.
Cons: ok but not great cooling, wouldn't want to run a hot drive in this full time, but then again why would you run a high performance drive in a USB enclosure.
Pros: I bought one of these to use at work. I work as a support techician and I needed something to be able to easily back up client data from a drive that won't boot for whatever reason so we can reimage their workstation. I've probably had over 100 different IDE/SATA hard drives attached to this thing and it has not once failed or fried a single drive. Works flawlessly.
Cons: A couple of the bore holes stripped on the cover so the screws don't tighten down the lid, but I use it opened face anyway all the time as I am swapping drives in and out of it constantly.
Pros: Some previous reviewers are misguiding you. This enclosure does have solid physical mounting for the hard drive. It has 4 mounting screws (with very large heads) that screw into the hard drive from the outside of the bottom of the enclosure. These screws perform a dual function; they physically secure the hard drive, plus, they conduct the heat from the hard drive to the aluminum housing of the enclosure.
Cons: It is a little noisy, but, noisy enclosures usually mean that they have plenty of holes in them for ventilation. This enclosure has a lot of holes on three sides. It is heavy, but, this is due to the construction being made of thick aluminum; thick aluminum means a better heat sink to radiate off heat. The 4 big screw heads that hold it together may scratch the top of the desk/table that it is sitting on, but, this can be solved by sticking some tape (or felt pads) on...
Pros: I love the design. I leave the top off and use it to diag customer HDDs. I have no I/O issues and never had a problem detecting a drive. Data transfer is as fast as an external gets without going firewire.
