C600 RAID 5 with SSD drives cause single drive failure under heavy load

[RCarr8]

I have a Intel Server P4000CP with C600 RAID controller. I have five SSD drives (Samsung 840 PRO 256 GB), configuration - one system drive and 4 RAID 5 drives. I am running Windows 2012 R2. All drivers and firmware at latest versions.

Problem - when copying lots of data from the RAID drive (backups) I will occasionally (once a week) get a failed status on one of the RAID drives. Using the Intel Rapid Storage tool I can select the "Mark as normal" property and it will rebuild the drive and put it back to "Normal". It is always the same physical drive that fails. I have replaced with a new drive. No help.

The system drive works without issue.

Any help would be appreciated.

Hello DSIRBC,

Thank you for contacting Intel Customer Support.

We recommend testing different sata cable. Can you also please let us know if you are using a backplane in order to connect the hard drives?

We will look forward for your response

Yes I am using an Intel HDD Cage 8 X 3.5. It has two drive bays (4 drives per bay), Each bay has its own I2C cable. I am only using one of the bays as I only have 4 drives. I swapped the cables and the problem, went away. I waited a few days before responding to make sure it was fixed. I will replace the bad cable if I decide to add additional drives in the future.

Thanks for your help.
