The "PATRIOT 64GB USB Stick XT RAGE" works when transferring small (.jpeg images, text documents) as large files (24bit WAV files, system disk backup) to my complete satisfaction. Brisk pace and so far no failures, (as opposed to my old USB flash drive, which is also like schonmal greased during operation. ~ ~ Groan) In addition, the design is really chic times (OK, that's a matter of taste) and the status LED will not flash to light. Since I anyway never wear my USB keys on a key ring, the protection extends to me without the cap completely. For me, it is finally the perfect USB flash drive.
Tips: On the manufacturing side there's a matching software with which I formatted the drive. ([...])
One can "Optimize for performance" to stick with Windows and thus enable write caching when you want. Also, I have to stick to convert NTFS because I can also save hard disk backups so that are large than 4GB.
