SAMSUNG BAR Plus 256GB - 400MB/s USB 3.1 Flash Drive Champagne Silver (MUF-256BE3/AM)

perfect

I became one of those stupid enough to be scammed by purchasinga Kauriea USB Memory Stick 2TB Flash Drive that turned out to be amere 32GB. Obviously I returned it and opted for this device instead.Works flawlessly. Despite my system only supporting USB3.0, largefiles topped out at 100MB/s write in Windows10 - Very Impressed.[EDIT]I use Linux Clonezilla to backup my windows and Linux operating sytems andalways at the end == CloneZilla does the "Waiting for flush writing buffers"Thing. The data is written to this device as fast as Linux can write it. :) NICE!

It's always hard to find a reliable USB of this capacity. Plenty of items on the market are USB 2 despite advertising them as 3. I checked the speed of the item and I can confirm is reliable

As stated

Not consistently high speeds, quite disappointed. When it's working well it is faster than any of my other USBs, but it often seems to fluctuate. It will go up to 28MB/s for a few seconds, then below 1Mb/s for several minutes, sometimes down to 0 for a while. Never seen it above 30MB/s either. Wish I saw the write speeds earlier.
