Generally speaking, speed is good. CrystalDiskMark shows 105 MB read and 68 MB write (4 GB test). And 118 MB for reading and 86 MB for writing (test 1 GB). In reality, I had a record peak of 70.9 MB. I was interested in writing speed. The flash drive's buffer behaves strangely. The schedule of record with any certain regularity "floats". It reaches a peak, then the speed begins to fall. It decreases to 710 KB, 1-2 seconds and becomes 355 KB, it stays at this speed for 2 to 5 seconds, then it rises again to 710 KB (and so on from 3 to 8 times), and then the speed starts to grow. It reaches a peak and starts to decline again. Screenshot charts. And this is on large files (from 4 to 5 gigs). I haven't tested it on a bunch of small files. Results. A 4.7 gigabyte file was copied to a flash drive in 4 minutes 25 seconds. For me, it's not particularly critical. bought in order to make a bootable flash drive-admin panel-first aid kit. For 290 - a sin to complain. Just surprised recording schedule. Moreover, on different computers (Win 10), the graph looks almost identical. In general, you can take.
