Question: Will this support a 4 TB drive?
Document: Bought this to make a backup drive for my mother in law. Used an older TB drive we had laying around. took about 30 seconds from start to finish,  works perfectly! Quality of the materials is also nice.
Went back to the company web site to see if they have any firmware updates to address the issue and there is nothing. Emailed support again but I doubt to hear anything back. Time to return and look at other options. If you are trying to use this with a drive larger than 2TB, save your time and look at some other product.Overall enclosure design is fine for what I wanted but without support for the drive it is worthless to me.UPDATE:I actually did get an email back from support.
Of course, the heat will transfer on all sides and I opted to keep mine standing upright.I put a 1 TB WD Black drive into mine. Some people are reporting that drives larger than 2 TB are not supported.
Despite checking all the reviews here and all the specifications and descriptions I could not locate what the maximum supported drive size was. I went to Sabrent's website to look at the specifications which provided a little more info. It did state "Supports any drive capacity". I emailed their tech support asking if the enclosure would support a Western Digital 3TB SATA drive but they never responded. So with what I could determine from their website I ordered the enclosure to see if it would work. After installing the drive and hooking it up to my Win 8 64bit workstation, it reported that the drive is a 746GB disk not a 3TB disk.
Something's wrong with the card in the drive.Wasted 4 hours of my life on this thing - even if it's just a fluke, I'd say it's poor quality control from the company. Stay away and get something a bit more reliable.
Absolutely loving this enclosure and planning to get more as the need arises.Pros:It's almost tool-less. You'll remove 4 'knobs' on the top to the unit to expose the drive bay. You put your drive in and that's that. 1 screw secures the drive from below (meaning there's no need to fiddle with the drive after it has been placed), since the screw-hole is available on the outside, there'll be no &#34;oops&#34; moments, where you've forgotten to secure the drive with a screw so you have to pull the unit apart again to do this.
The thumbscrews would beat up nearby equipment and the case can &#34;gap&#34; if distorted. It also has nothing but paint between the bottom of the drive and the bottom mounting plate. I also only holds the drive by two screws, rather than 4 (and they shipped 4...weird). Mind you, many desktop computers have a similar baseplate mounting scheme, so this case should be fine for stationary use.Other items worth mentioning are a power switch and AC adaptor - both good features.So, good features are: Cooling.
I originally purchased 2 of these to take advantage of some spare 750G and 1TB SATA drives I had. both drives worked great on my Windows 7 PC. I am using these on USB 2.0 and USB 3.0 ports and both worked with no issues. Installation is quick and easy. The case cover uses thumbscrews making it easy to remove the cover. The drives I have allowed use of 2 of the 4 included screws to secure the drive and a small screwdriver is included. The USB cable is included and is high quality.
You get what you pay for. I chose this solely for the price and having USB 3.0 isn't too shabby. Transfer rates seem to be good, but the overall construction of the enclosure doesn't seem to feel completely sturdy. Basically, you have the bottom with the 4 corner columns with grooves cut into them to allow the removable sides to come out (makes a slight rattling noise when the drive is on), the power and SATA cable placement on the internal board need to be switched, the SATA cable is secured to the internal board but I was afraid I would break it as I had to maneuver my drive into the enclosure.
This is a roomy enclosure. The first one did not work initially, but got it working when I relieved the stress on the cables. The data cable is about 1/4&#34; too short to easily connect and mount the drive. Data cable is secured well onto the circuit board to avoid the stress pulling it out of the interface board..Enclosure is easily accessible without tools. Have to be careful when taking it apart or it will completely come apart.Heat buildup should not be a problem since there is a lot of space for heat to dissapate.Hardware is sturdy and is not flimsy.External data cable is quality and is plenty long enough to use
Answer: This case will NOT support a 3TB or 4TB drive.    It has a 2TB limit.
