Using the Synology RAID calculator to compare SHR vs. The last drive stores parity data for that stripe, for redundancy purposes. RAID 5 is a storage technology that combines data striping with parity to achieve a reliable and efficient data storage solution.So an eight spindle RAID 10 array would be N = 8 and X = 125, and our resulting calculation comes out to be (8 * 125)/2, which is 500 WIOPS or 4X WIOPS. It is noteworthy that the calculator assumes that all the disks in the RAID array are of the same size. All of our charts relate the performance of RAID arrays at .

A 50/50 blend would result in 750 Blended IOPS (1,000 Read IOPS *. RAID 5: If you have n drives of capacity c, then the array .In short, RAID 5 arrays distribute data across multiple drives while using parity information to recover lost data in the event of disk failures.For instance, TrueNAS uses RAIDZ and RAIDZ2 when referring to RAID 5 and RAID 6 configurations. See the description of the –size option:-z, –size= Amount (in Kibibytes) of space to use from each drive in RAID levels 1/4/5/6. Higher signals indicate a higher probability.You can check the missing other drives and XOR of the remaining data will always give you exactly the data of your missing drive.This is the lowest rate of RAID redundancy and is also known as mirroring since identical data is duplicated across two drives.
