RAID 5 was Great, until High-capacity HDDs Came into Play, but SSDs Restored its Former Glory

RAID 5 was great, until high-capacity HDDs came into play, but SSDs restored its former glory.(+) New tech becomes obsolete and forgotten at an astonishing speed. However, sometimes it’s enough to develop another approach and all the old technology may become relevant again. This happened to RAID 5, because HDD capacity grew, but spindle speed had mechanical limits, which eventually made RAID5 too volatile. With modern high-capacity HDDs, RAID 5 became unreliable, because it remains in a failure-prone state for a long time. Seek speed remains the same, while capacity grows, so rebuild time grows as well. This means the … Continue reading RAID 5 was Great, until High-capacity HDDs Came into Play, but SSDs Restored its Former Glory
