I once ran into a RAID card that would write bad data if you put it on a 90-degree PCI connector (needed for a 2U server box). No errors appeared anywhere until you encountered corrupted files.
- bashinator 6y agoHardware RAID falls into the "never again" category for me.
- nitrogen 6y agoThough in this case it sounds like any PCI card that couldn't handle the degraded signals from the angle connector would have exhibited data corruption. I have problems with USB packets getting corrupted on their way to my audio interface. Signal integrity is really underappreciated in the PC peripheral world.
