Hardware RAID disadvantages

Drawbacks of hardware RAID
Hardware RAID-6 constitutes a significant (and unnecessary) portion of investment to storage system.

Many hardware RAID controllers offer RAID-5 but not RAID-6. However RAID-5 is not suitable for storage systems due to its poor reliability.

Whenever required storage capacity is up to or exceed the combined capacity of 2 HDDs RAID6 is a solution to eliminate downtime in case of HDD failure. With redundancy enough to survive loss of one or two disks RAID6 […]

That is, with traditional parity based RAID systems, if the said systems are unable sustain and recover from a particular failure level then all data is lost. This chronically negative aspect of […]
