JW063 Dell Perc 6/ir Pci-Express X8 SAS Raid Controller For Poweredge R200

The Dell JW063 PERC 6/IR PCI-Express X8 SAS RAID Controller provides data protection by offering RAID levels that provide data redundancy. RAID 1, for example, creates a mirrored copy of data across two hard drives, so if one hard drive fails, the data is still available on the other hard drive. RAID 5 provides data protection by striping data across multiple hard drives and using parity to allow for data recovery if one hard drive fails. RAID 6 provides additional data protection by using double parity, allowing for data recovery if two hard drives fail. With RAID 10, the data is striped across multiple mirrored pairs of hard drives, providing both speed and redundancy.
