What is the best RAID for performance?
If you need solid performance but also need a level of redundancy, RAID 10 is the best way to go. Keep in mind that you will lose half your usable storage, so plan accordingly! Redundancy: If redundancy is most important to you, you will be safe choosing either a RAID 10 or a RAID 60.
How much faster is RAID 10 than RAID 5?
When you have applications that require fast read/write operations, RAID 10 is the right choice because it doesn't manage parity, so no checks are necessary. In fact, the read performance of RAID 10 is twice as fast as RAID 5.
Is RAID 5 as fast as RAID 0?
For read access, a RAID5 is expected to have similar performance to a RAID0, in theory even a bit better if the access is seek-time bound. i.e. for a total cache miss, a single write in RAID0 translates into n-1 reads and 2 writes for a RAID5.
How to calculate RAID size?
Therefore, the usable capacity of a RAID 5 array is (N-1) x S(min) , where N is the total number of drives in the array and S(min) is the capacity of the smallest drive in the array.
