{"Image DocumentName": "Hardware IssuesSoftware RAID: RAID implementations done entirely in software, with no special hardware support.", "Image ImageDescription": "Hardware RAID: RAID implementations with special hardware. Use non-volatile RAM to record writes that are being executed. Beware: power failure during write can result in corrupted disk. E.g. failure after writing one block but before writing the second in a mirrored system. Such corrupted data must be detected when power is restored. Recovery from corruption is similar to recovery from failed disk. NV-RAM helps to efficiently detected potentially corrupted blocks. Otherwise all blocks of disk must be read and compared with mirror/parity block.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
