Which is faster RAID 1 or RAID 5?
Every transaction of read/write requires writing on parity disk in Raid 5. In Raid 1, as there is no parity disk available, the transactions are faster than Raid 5.
Why use RAID 5 instead of RAID 1?
RAID 5 arrays have relatively slow write performance because parity information must be written to the disks alongside the actual data. RAID 6 arrays are even slower because they store a greater volume of parity data than RAID 5 arrays do.
Does RAID 5 slow down performance?
RAID 5 – This is a common configuration that offers a decent compromise between security and performance. It requires at least three disks and provides a gain in read speeds but no increase in write performance.
