Review on 💾 Pack of 5 - SanDisk Cruzer Ultra 16GB USB 3.0 Flash Drive SDCZ48-016G-U46 with Speeds up to 100MB/s by Andre Young

I formatted it to NTFS and tested it with a huge 7GB ISO file. The 7GB write speed started at around 25-40MB/s but then dropped to 13MB/s. 7GB read speed supports 150+ MB/s for the entire file. Wow. It warmed up while reading a huge file, but stayed colder than expected. great product Great. Except that large writes of several GB are quite slow.--------------- -- - ----------- EDIT - December 2019 This is the last batch, which I have just received in identical packaging to the previous SDCZ48-016G-U46. You no longer have a blue activity LED.GRRRRRRRRR. reduced the number of stars to 3. --------------------- EDIT 3-2020 The packaging of this last batch is marked as 130 MB/s. But exactly the same performance as before. Writes very slowly. Reading is very quick. The blue activity indicator is back. :)
