What is the expected speed of the current blue Flash Voyager?

[Petr]

Does anybody know what is the expected speed of the current blue Flash Voyager sticks?
I have measured my two recently bought sticks:
CMFUSB2.0-4GB: read 33.4 MB/s write 6.5 MB/s
CMFUSB2.0-1GB: read 15.0 MB/s witte 2.9 MB/s
The write speed seems to me too slow.

I have read the announcement that due to change from SLC to MLC chips the write speed is slower now, but is this what is expected?

As I know, it is about 32.1/22.5 MBps sustained throughput, I had used hd speed to test flash voyager.
