SA B140i vs B120i Extrem Slow Performance with the B140i

[kunzibus]

Hi Guys!

I have a problem with the new B140i Raidcontroller. I have two Samsung SSD 850 Pro 512 GB in a Raid 1.

The Old Microserver with the B120i is much faster than the new Proliant ML 30 with the B140i.

Look at the 4K Randow read/Write.

The Write Cache for physical Drives is activated. But the new Server is now much slower than the new one. So its nearly useless. How can i get the speed of the B120i back. Thank you in advance

regards

searching this forum. I found a solution

It is only fast with an old driver.

But how can i install the old Raid driver. do i have to uninstall first.

Thanx in advance
