QZ 3.5 inch USB 3.1 SATA Hard Disk External Enclosure Case for 3.5/2.5 inch Black

Awesome product.As a test, I tried using to have old SATA hard disks (8 years) that were making "clicking noises" & does not recognise when connected to internal computer cables. As hard disk used to make noises or were not recognising properly either due to power outages in our area, I used to buy new ones.Now with this product (QuantumZERO QZ-HD01 USB 3.0 SATA Hard Drive), the clicking noises is not there surprisingly & ALL the OLDER hard disk is USABLE, though there seems to be performance issues when multitasking (copying data & playing video). At least, I was able to copy the data to & from the disk. Now since the hard disk usable, I can use the older SATA as 2nd backup for data :)Now I have lots of OLDER SATA hard disk lying around that are usable. Great.I bought the product for Rs.1,680.00. I was worried about investing more as there was other alternatives with lower cost. The reason I went for this product as it has a USB 3.0 (though sparingly used since OLDER hard disk will not give better read write after long usage & with clicking problems or other issues)Something to be aware of.1. The product comes with a on/off switch (with Blue light indicator). This is good if you want to change hard disks without removing/switching of power cord or if you just want to power cycle the VERY OLDER hard disk as sometimes they do not respond after sometime of usage.2. The green light indicator is always on when the USB cable is connected to computer even though the Power switch is off (Guess, the green light indicator for USB connection does not require external power)3. Quality of the product - hard plastic is very good.4. I use the product to backup data to backup hard disk & then disconnect the power. I have not used the product for continuous usage as a primary hard disk & directly playing for videos/audio. Though it can.Don't think, just buy the product, you will be amazed that you bought the product. All your older SATA hard disk can be used at least as a 2nd backup for data (as this was I intention to buy the product - for secondary backup).

Best product to connect internal hd externally

I bought this with great skepticism. I had 2 old hard disks. It was possible to extract data from all of them very quickly. Very good item. It has good build quality. It was a good experience. Thanks Amazon.

Worst product .don't buy this product.I have purchased but can't working properly.it would be heating lots of. and didn't connect on laptop whenever disk connect.

Pros:A very good device that performs exactly as it is advertised to, i.e., doing the seemingly simple task of converting a SATA III HDD interface to a powered USB 3.0 port. Why do I say "seemingly simple task"? That is because over the years I wasted quite a bit of money purchasing devices advertised to do just that but (may be it is just my bad luck) all my previous purchases were fruitless! That is, the devices (starting with two such old USB 2.0 ones) I purchased either failed immediately or after merely a few months. Following some reviews seen on the internet I started to believe that the power supplies provided with these devices are invariably inadequate. Not true! May be "mostly" but not "invariably". The proof lies in this Quantum Zero enclosure that I am now regularly using with a 2TB WD SATA III HDD (Blue) without any problem and in amazing data transfer speeds (125MB/sec to 130MB/sec write and 145MB/sec to 150MB/sec read). This same HDD when used in a nice looking Orico enclosure, reported data transfer errors every time on repeated attempts. Finally I tried my luck with this Quantum Zero enclosure and, boy, am I glad that I did!Cons:1) Poor ventilation. There are only some narrow slits at the bottom, not enough for adequate ventilation since the shoes or buffers under the box are so thin that there is not enough room for adequate air circulation. I thought of drilling a few quarter inch holes in the top cover, but ultimately settled for the easier solution of simply keeping the top cover off as long as the HDD is running, and 5-10 mins thereafter.2) I wish that Quantum had given some thought on the aesthetics of this great device. It has a peculiar dirty black color on the outside that has a rough (not decently grained or glossy) finish that makes it look really old. Out of the box it looks downright ugly, if you will please excuse my expression!Bottom line: It works! You should definitely buy it if you can live with its dirty old look!

Working fine. No issues detected till now. Happy with this purchase.

Very good product
