After some Googling, I even found sites like this one by Blackhat Research that detailed extensive testing done on these lower-end RAID cards proving our suspicions true. The Dell forums had numerous posts like this describing issues with speed, and the fine folks at Spiceworks were seeing the same problems. It seems that we weren't alone in our sluggishness using default settings on the PERC H200 card. Related: Mixed news for the server market: It's growing, but not by much Even the SAS cable we used was a brand new Startech mini SAS unit, freshly unwrapped from the factory, and otherwise testing out fine. The hard drives were brand new, along with the RAID card. All of the internal hardware on this server tested out just fine. The problem? After we loaded on a fresh copy of Windows Server 2012 R2, things just seemed strange. It also doesn't help that the R210 only has a pair of 3.5in internal drive bays not the four to eight hot swap bays we usually have at our disposal on T4xx series Dell servers. Our storage needs for this client were rather low, so employing Windows Storage Spaces was a moot point for this rollout. We paired a dual set of (rather awesome) Seagate 600GB SAS 15K drives together in a RAID 1 for this H200 controller so that we could pass a single volume up to Windows Server 2012 R2. And this described the exact situation we were in for this customer Dell R210 rebuild.
