WebMar 3, 2024 · However, the write performance of a RAID 6 array is slightly slower. Specifically, the slower write speed of RAID 6 is due to the additional parity information that needs to be calculated. This means that, if implemented with the same number and types of disks, a RAID 6 array may be marginally slower than a RAID 5 array.

WebJun 21, 2024 · The Motherboard is SATA (version 3) at 6GB/s and the drives are (version 2) 3GB/s. Write speed on Raid-5 are directly related to the number of drives you use. If the drives are rated at 100MB/s for example, 14MB/s is the theoretical maximum you are going to see plus the overhead of the parity calculations and whatnot. WebAverage seek time for a Seagate Cheetah 15K6 is quoted at 3.5ms for reads and 3.9ms for writes (I presume the writes include a period to align the head on the servo tracks). A 10K disk is slightly longer. So, a raw estimate is an average of 5.5ms per random seek for a 15K drive and 7ms for a 10K drive.
