HDTach 2.61
Random Access Time
Unlike the SisSandra benchmark, HDTach was able to show how mirroring could actually improve random access time. It's only logical that already having two hard disk drives with similar contents, accessing a particular file should be a lot faster. Otherwise, the performance of the other configurations were generally the same.
Average Read Speed
Again, we are reminded of how fast RAID 0 is compared with the other setups. When RAID 0 was set to stripe sizes from 1 KB up till 16 KB, the read performance became blistering fast! If your applications transfer load and loads of files all the time, these setups may serve you well.
Average Write Speed
While large stripe sizes may be really bad at data reads, they seem to excel in data writes! Here, they more or less dominated the charts. However, the stripe sizes of 2 KB, 4 KB and 16 KB also performed very respectably.
Obviously, the best stripe sizes would be 4 KB or 16 KB as they are both good in read and writes. The slightly faster write speed of large stripe sizes can't really make up for their rather bad read speed. We can also see that mirroring takes a major hit in performance during writes, due to the need to write the same data twice.
