Pros: Easy to open and install drives.

Cons: I bought it 14 months ago and put in two Western Digital 1.0TB Green drives. Most of the time I left it powered off. With no warning it failed to operate. The power light comes on but the PC does not see the drives.

Other Thoughts: I thought by leaving it powered off most of the time the unit would have an extended life, but now I have to buy a replacement enclosure. A 1-year extended warranty would have done me no good since it failed after 14 months.

Pros: Much smaller than I expected it to be with good quality construction and a nice attractive finish. The drive connectors inside are sturdy with a nice snug fit. Very good value when I grabbed it on Shellshocker.

Cons: My fan is quiet, but doesn't seem to move much air. No screws in my box for installing hard drives so be sure you have some on hand just in case. Screws to secure the body are really tiny so you need to be extra careful to avoid stripping.

Other Thoughts: I needed to combine two older drives to become a backup location so I am using Big format and its working perfectly. A huge improvement would be if it would allow the drive to fully spin/power down for power savings, which is a common shortcoming of these kinds of enclosures.

Pros: compact design, looks nice, not loud, fan switch, metal body dissipates heat

Cons: Hard drives get hot inside, instructions are poor but get the job done. Just flip the switch to the mode you need to use.

Pros: Very easy to assemble. Solid construction. Runs cool and quiet. Comes with a stand and all the cables you need. Fan has a separate on/off switch. Also comes with mounting screws for your hard drives, in case you don't have them already. Works with Windows and OSX right away.

Cons: No Firewire ports. USB 2 only; No USB 3. Needs an external power source to operate; can't run off USB power only.

Other Thoughts: I had two drives that needed an enclosure, and this was exactly what I needed. Assembly was fast and simple, and both drives were recognized by Windows 7 and Mac OSX 10.5 without any additional software. Don't be intimidated by the sparse instruction manual. If you can use a screwdriver, you can put this enclosure together.

Pros: This is a great little box. Well made, sturdy, fits together snugly. The drives fit into the rails easily but tightly, and connect well with the SATA power and data contacts. After loading two 1 TB drives and using it for a few days, I ordered a second one of these units for future use. I appreciate being able to use the two drives independently. The USB external connection is slower than eSATA, of course, but I use these drives for backup of digital images, so the slower access speed isn't an issue. I'm using two WD "green" drives, which don't get as hot as the others, and the case barely feels warm on the outside after several hours of use. The fan is very quiet, and has its own switch.

Cons: Only downside I can think of is the lack of an eSATA connection, but computer manufacturers aren't rushing to add eSATA ports the way they once added USB ports.

Other Thoughts: All around, this is a great enclosure

Pros: Cheapish
Does big (basically raid 0)
holds 1TB drives, haven't tried larger

Cons: none yet

Other Thoughts: Running 2 1TB seagates in BIG on my mac, works great.

Pros: I picked one up before deploying to Afghanistan so that I could keep a back up and consolidate my other hard drives into one. i used two 1 TB drives for it, and have yet to have a problem 4 months later. It has been through traveling in military bags and the heat and hasn't had a hick up. After being here for a bit I ordered 9 more for my shop and only one of them was DOA. We were able to just fix a solder join on the board and got it up and running again in less than 30 min. All 9 of the ones I picked up out here have two 1.5 TB drives in it and they all have been working smooth for about a month now.

Set up is quick and painless, 4 screws on the back and 4 screws per drive.

Cons: none

Other Thoughts: for the price you can't go wrong

Pros: Sleek, looks good, good length power & USB cords. Easy to setup & use! The little booklet that came with the device explained everything you need to know. Lights from the enclosure is discrete (not insanely bright like other enclosure I've used before)

Cons: Fan's a little loud, but not a big deal. You can also turn the fan off if you'd like

Other Thoughts: Great device! Would recommend it to anyone!

Pros: Great price (on sale), easy to use and setup, good build quality and compact.

Cons: esata version is way more expensive

Other Thoughts: This is the best hdd enclosure I have found at any price, holds 2 hdd compactly and made of nice aluminum. Note- back 4 thread hole are open-so finger tight MAX and I needed to drill a bunch extra holes in front cover to keep them cool in my Warm room, otherwise you can take the front cover off.

Pros: Easy to install HDs, plus I like the options of how to run the pair of drives. I am running 1 TB Black WD

Cons: None

Other Thoughts: This is a great way to keep things backed up. I like this setup much better then buying a unit with a drive already installed as this setup gives the option of choice the brand and type of drive you want to use.
