20 Pack Bulk 8GB USB Flash Drive, MONGERY USB 2.0 Memory Stick Swivel Thumb Drives Jump Drive for PC Laptop Computer (20Pack, 8GB)

These drives contain roughly 14.6 GB of usable memory, which isnt too out-of-place for drives marked 16 GB, but can be a sour disappointment for someone looking for exactly 16 GB of capacity. The issue comes with data transfer. A constant stream of transfer hit the usual USB 2.0 speeds (around 6 MB/s write, 11 MB/s read) but speed suffered greatly when moving nested folders of small files totaling up to 300 MB. My speed dropped down to roughly 5 KB/s, and occasionally would halt file transfer altogether for roughly 2 or 3 seconds. My only current, realizable use case for these drives is bootable operating systems. I would not recommend these drives to a power user. I would recommend these drives to those who do not do many file transfers, but still require their small-size data (slideshows, Word/text documents, et c.) be stored elsewhere.

Solid devices. Work great with no issues. Very good value for the money

Love these, they are great for need that I have. Will order again when needed.

This is great for a quick plug and play flash drive but it does not store all documents or comes back with an error about operations.

I used these flash drives for a virtual conference for storage and also for displaying a presentation slide before each class. They worked flawlessly! I plan to use them in my normal video work too. Lots of memory for my larger video works!

Easy to put pics on the drives!

Had the only 2 used die after brief periods. Multiple “bad block” addresses found and unable to reformat. Using disk recovery software found true manufacturer is VendorCo ProductCode - reputed to have a high number of products with falsified capacity. Using these entails a high assurance of data loss. Stick to a reputable name brand. I am tossing the remaining 18 purchased as too late to return and utterly unreliable.

Worked perfectly with my Elna expressive 770.

I transfer data onto numerous flash drives every week. Both 2.0 and 3.0 drives. I have never seen data transfer as slow as it does on these drives. Its mind-numbingly slow. Six hours to transfer 5GB of data?! Thats absurd and unheard of. If I were you Id try a different brand by a different company. These drives will waste your time.

Ordered these to backup excel files for a non-profit organization for which I was the treasurer. After about a month, one of them failed and I was unable to open the files stored there. The others seem ok.
