not useful for large files and amounts of data

Unfortunately, I did not really believe the Rezesionen and chose this USB stick to my three old to a new one with 16 GB of storage unite. This project was completed only after about one hour, I only then noticed that the write rate between 3.5 and 4.5 MB / s was. This is totally unacceptable for a storage medium of this size. If you want to copy large files is especially with this USB stick tart disappointed.

I can understand the details of the previous Rezesionen only confirm:

Write rate: 4.5 MB / s
Read rate: 15.5 MB / s

I tested with a 1GB file, the copy process at about 2.5 MB / s and then slowly began to 4.5 MB / s high ran.
The large the SanDisk Cruzer Blade 16GB USB Memory is the only positive thing aufällt, but does not weigh on the poor performance.
Test environment: Dell Precicion M4500, Core i7, Windows 7 Enterprise

My Conclusion:

Useful for the private sector for small and large files.
For business applications rapidly large numbers of files in my opinion copying not recommended.
