Make a note: 1. Write speed in "Disks" tool is one thing. 2. The real write speed (e.g. during normal copy files) is other thing.
1. For "Verbatim" the "Disks" tool shows good results: - Verbatim: 87.7 MB/s (read), 183.4 MB/s (write), 18.07 (access) - GOOD RESULT - Seagate Expansion: 36.8 MB/s (read), 34.6 MB/s (write), 23.95 (access) - BAD RESULT - Kingston DT Ultimate G3: 186.9 MB/s (read), 7.9 MB/s, 0.85 (access) - VERY BAD WRITE RESULT Results via "Disks" tools are the same with no matter what kind of filesystem it is (FAT32, NTFS, EXT4). 2. The real write speed (e.g. during normal copy files): - Verbatim: in 13.04 was about 50 MB/s (NTFS), now on 13.10 is bad - about 30 MB/s (EXT4). - Seagate Expansion: as I remember in 13.04 was 10 MB/s (NTFS), it was much worse than Verbatim (NTFS) . - Kingston DT Ultimate G3: is very bad all the time, about 17 MB/s (NTFS), sometimes about 10 MB/s (NTFS). The real write speed depends on filesystem type and type of copied files. NTFS is the worst. EXT4 best.
