ULTRIUM SAS External 1760 transfer rate

[Cam oipo]

Hello !

We bought an ULTRIUM SAS External 1760 with
an a sas card single channel from HP (LSI 3000).
We installed all with :
HPTapeDriversInstaller.exe
cp009394.exe
hp_ltt47_win.exe
all is recognized and working except that the transfer rate is not what we wanted(from 1.7GB/M to 2.1GB/M)
when we are testing the speeds with HP Storage work, it tells us that the speed is severely limited.
Does someone have an idea ?
Thx in advance
