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

Good Product

Works great! Everything is as described by the product description! To write about why this is a valuable purchase, I had a 2TB external hard disk, which stopped working. I took out the internal hard drive, and bought a cheap usb 2.0 external case, which was clunky to install, and very slow. Now, as I took out the hard disk from the previous case, and installed it into the QuantumZero QZ-HD01, not only was the installation process very easy, intuitive, and fast, the transfer speeds are amazing, as USB 3.0 provides. Great idea, thoughtfully executed, and a very nice product overall. I think the Rs 1680 price tag is a little too expensive for right now (3/11/2017), but the more people buy this product, the cost will hopefully come down and balance out in future. Overall, I am happy

I wanted to replace my computer's HDD with an SSD, so I bought this product to keep using my old hard drive via USB. It works exactly as advertised. It supports both 3.5" and 2.5", SSDs and HDDs. In the box I got the hard drive case/adapter, a USB cable and a power adapter. The entire case is plastic, but it is of good quality and seems long lasting. I am writing this review after two weeks of use. I have used it every single day, leaving it connected to my AIO desktop at all times. There had been no problems. It works perfectly fine with both 2.5 inch and 3.5 inch SSDs and hard drives. In the overall, I am very happy with my purchase. Nevertheless, here are a few things to note before you buy this: The USB cable is thick and would be a bit difficult if you are using it with a laptop or anything that needs to be moved around but it is perfect if you don't intent to move it around a lot. Also, both 2.5" SSDs/HDDs and 3.5" HDDs require external power from the power adapter (2 pin, wall mountable), which further restricts portability. If you are specifically going to use a 3.5 inch hard drive, then this is the best choice for an external SATA III to USB adapter but if you will use only a 2.5 inch hard drive or an SSD, it would be a better option to go for a 2.5-inch-only adapter like ADATA ED600 that is cheaper, portable and does not require an external power supply.

Bad product. Not working after 6 months

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).
