I have tested the Raidcontroller with Writecache and without. But I have very bad Performance. I can write to the Disc with max 5 MByte/s. With this Speed I can't work. The Raidcontroller has no Battery Pack.

Can you help me getting a better Performance?

Best Regards

Re: Slow Performance ProLiant ML150 Gen9 HP B140i

The B140i is a software based RAID controller and uses resources shared with the host system.  You will not see performance levels provided  by a hardware based RAID controller.

From the users guide:

The HPE Dynamic Smart Array B140i RAID controller is a RAID solution combining SATA ports and proprietary software components. Eliminating most of the hardware RAID controller components, and relocating advanced RAID algorithms from a hardware-based controller into device driver software lowers the total solution cost, while still maintaining comparable RAID protection and full compatibility with Smart Array disk format, configuration utilities, and management/monitoring software.

You will have to look for a hardware controller to be able to improve the writes and readings in any of the disks. I have a ML110 G9 that has the same software controller that you are commenting on, and the same thing happened to me (as well as many other people who have commented on this forum), so I decided to buy a P440 4GB from HP Renew and the difference is huge. Search for compatible controllers for your server model, I assure you that the difference is very large.
