RAID 6 is preferable in excess of RAID 5 as a consequence of the additional standard of fault tolerance. It’s an all-spherical program that mixes effective storage with fantastic security and respectable performance.
On the other hand, two 5TB drives will frequently be a whole lot less costly than five of 2TB. Do Notice that Otherwise all drives within an array are of precisely the same dimension, all drives will default to the smallest travel within the array.
It’s not about how lengthy HDD or SSD could endure in RAID 0, it’s about what's going to occur when failure takes place.
