Raid and erasure coding
WebSep 2, 2024 · RAID-5/6 erasure coding has predetermined capacity savings when compared to RAID-1 mirroring. This is your chance to immediately save capacity and reduce your TCO. FTT=2 using RAID-6 will consume just 1.5x when compared to 3x for FTT=2 using RAID-1. Higher levels of resilience. WebJul 26, 2024 · Erasure coding breaks the data down into fragments that can be expanded and encoded with redundant data pieces. When compared to RAID, erasure coding can reduce the time and overhead that comes with reconstructing data. General industry trends also play a role in the move away from RAID.
