Flash Pendrive Dual Memory Storage Stick USB C Jump Drive for Mobile/ PC/Laptop l-Tersanhong(Black)

Its hard to complain too much about a 2TB USB drive that costs only $21 . But this drive is SLOOOOW! There's no way this is USB3.0 - which should get at least 100-250Mbps on the slow end. I used the USB-C plug directly into my new Macbook Pro's Thunderbolt 4 port (way faster than USB3.0). It took just under 3 HOURS to transfer a folder that was just 85 GB. Even at 100Mbps it should have only taken about 15 minutes for that transfer. This might work for some longer term backups or smaller files that don't need to load fast. But it won't cut it for larger files or anything that you need to read/write to the computer quickly.

I got my flash drive set up and backed up my entire laptop. It is a nifty little USB, but after about two weeks, the whole cover came apart. I had to find it to work so I could back up all the data on another flash drive. Whew! I am glad I didn't lose any data!

WARNING: Don't purchase this USB unless you want to lose all your data, media, and files. It failed on the first use and I lost everything on my phone in the process of moving everything and cannot retrieve it from the flash drive anymore. I am expecting full refund and compensation from the seller.

Absolute trash I copied 100GB to it and couldn't read the first files thart were written... this is a very good indication that the size of these flash drives aren't even close to the advertised size because files that were written to the flash drive initial are being overwritten by files being saved to it later.

I tried using this a primary storage device between a few different computers and around 60gb it started corrupting new files. I'm going to assume that means it's a 64gb drive that lies to you, but I haven't tried reformatting it to match that. The cover on the thing is flimsy, but, to it's credit it's very portable. If want cheap high volume storage, please look elsewhere.

Item is defective. I ran a 100 Mb write/read test on a Windows 11 laptop. Here is the outcome: Only 100 of 1999936 MByte tested. 13 KByte corrupted (26 sectors) First error at offset: 0x00000001027ea800 Expected: 0x00000001027ea800 Found: 0x00000003027ea800 Writing speed: 6.65 MByte/s Reading speed: 17.6 MByte/s

This is a scam disc that over reports. It is not even close to 2TB and you cannot change it as it is flashed to the chip. I should have known better but Walmart logo made me think it was a holiday offer, as it is running in ads.

This device has had errors ever since I first plugged it into my laptop. Windows can't even partition the drive without getting errors…pretty useless and a waste of money.

Piece of junk. Mounted, failed more than worked. Could write some files for maybe 15-30 minutes, but then would fail. SLOW... took days to properly delete the files off of it for return. Would NOT recommend.

ran h2testw and this "1tb" drive can only store about 60gb of uncorrupted data meaning they are actually selling you a 64gb flash drive with tampered firmware and it only supports 2.0 speeds
