There is no more practical and visual way to test flash drives than CrystalDiskMark 2.2: . Kingston DataTraveler SE9 - "8GB" - FAT32 - Sequential Read : ~ 21 MB/s Sequential Write : ~ 13 MB/s Random Read 512KB : ~ 21 MB/s Random Write 512KB : ~ 7 MB/s Random Read 4KB : ~ 2 MB/s Random Write 4KB : ~ 0.7 MB/s .

I translate these figures for housewives with stopwatches: all speeds are above average even among flash drives of larger size and price. Made in China/Taiwan. The connector is inserted tightly, does not dangle. Slightly warm when working. Very strong case - it will not be possible to break it with bare hands. Especially considering the current situation - 190r / "8" GB, 310r / "16" GB and 620r / "32" GB - I don’t even see real competitors in the distance in terms of compactness * reliability * convenience * speed / price.
