🔁 Efficient and Compact EZ DUPE USB Duplicator - 1 to 4 Standalone Flash Memory Drive Copier (Mini USB Plus) Review

I'm trying to duplicate 4 x 1TB USB sticks and all errors (red LED). If I just plug in a single 1TB USB stick, it works. I tried it with two 1TB USB sticks, error again (red LED). However, there are no problems with small capacity hard drives (e.g. 8GB / 16GB).

I bought this hoping it would work with 128GB USB sticks and it worked fine. It made sense to only copy the actual data and not the entire media, which saved my life. The other good thing is that I didn't have to press any button to copy because there is no button at all. As long as I had the master and blank USB drive plugged in, it would start copying automatically. This little USB copier is cool!

This is the only inexpensive and reliable solution I could find with more than two duplicates. It even transfers boot disks. I took it out of the box and ran the first two groups.

The next viable fix cost over $500 and it only got worse from there.

I requested a replacement device after I received the first device (I thought), but the second device also gave an error when copying very large video files (8 GB) . or more) on the original FlashDrive. It seems to work fine when copying video files under 1GB, so I put it back. The device feels solid and very well built, but it's no use if I can't copy large flash drives even with more expensive USB 3.0 drives. It didn't seem to matter if the source drive was formatted NTFS or Ex-Fat, it still…

I had to copy over 100 flash drives (fd) with 3.2GB of information to new 16GB preformatted flash drives. Round one: Followed the instructions. All 4 fd uploaded to duplicate. After a while, 2 fd flashed red, which indicates a malfunction of the fd. 2 more exchanged and measured. Duplication time was 12 minutes with all 4 turning green at the same time. The duplication time was 12 minutes, which is 300% slower than the advertised time. Try again. round two. 4 more loaded 3 of 4 flashed red…
