![]() The 2007 generation of this PCI card uses a blue PCB board the 2009 version features black. Mac Pro RAIDĪpple made two versions of the Mac Pro RAID Card, issued at the same times as corresponding versions used in Apple's XServe servers. In all these scenarios, a RAID card installs in your computer and controls internal or external hard drives. RAID 5 also combines the attributes of levels 0 and 1, but emphasizes data-reading performance over data-writing. RAID 3 uses striping and redundancy, with less setup cost than RAID 0+1. RAID 0+1 combines the performance and data-security attributes of levels 0 and 1, but stores only half as much data as its drive capacity. RAID 1 uses mirroring to echo data on more than one drive, protecting files against hardware failure. If one drive fails, the entire data set becomes inaccessible. RAID 0 shares file-access chores among a set of disks, striping chunks of a file on sequential mechanisms for high-performance access. ![]() ![]() You can set up RAID in five different levels, each with its own performance characteristics. RAID stands for "Redundant Array of Independent Drives" or "Redundant Array of Inexpensive Disks." It transforms multiple off-the-shelf hard drives into a large, fast storage mechanism that your operating system sees as one drive.
