Benchmark: Kingston DataTraveler 101 DT101 G2 16GB

I was curious about Kingston USB flash performance. The overall performance is poor.

Write performance: 3.7 MB/s
ReWrite performance: 3.0 MB/s
Read performance: 22.5 MB/s
Random Seeks: 4.3 / sec

Comparing to Samsung S2 Portable 500GB USB 2.0 External HD:
9.4 times slower for write
5.7 times slower for rewrite
2.0 times slower for reading
28.79 times less seeks / sec

Full performance output:

[root@ace ~]# bonnie++ -n 0 -u 0 -r 7000 -f -b -d /mnt

Nice information about such a slow write performance usb stick.

I get crazy waiting to write data on it. I found it fast when I read data. I copied data to format to NTFS and after that took hours to recopy data in it.
If I read your post before I wouldnt format my usb stick.

Thank you
