SSD Writes


Hi there,
I am facing an issue with SSD write speeds.
I am running on Centos 6 with multiple SSD drives.
When I do a hard reboot via KVM, the server is online and the write speeds are perfect. However after a day or two passes, the write speeds are very low almost 5 times lower than normal.
If I do a reboot again, the speeds are back to normal but go low again after 1-2 days.
What exactly might be causing this, any ideas?
Thanks for your suggestions.

Just as a test...

Do you have a RAID card? Can you turn off write caching?
