You would need at least 10 HDDs to achieve that kind of throughput, and only if you write large files.įurthermore, copying from one partition on the RAID to another partition on the RAID means the RAID array has to do both reads and writes. So if your scores start with 1GB/s then that doesn't mean the HDDs are processing that much they can't and the SATA cable cannot either not even for 2 disks in RAID0. So the first 1 gigabyte you basically got for free in less than 0.1sec after that you are hitting the real physical write speed. You can see 0.6MB/s is the max for reading 4 kilobyte files.Īlso, if your speed begins with 1GB/s than that means your OS is buffering writing to RAM first. Speeds will drop the lower the file size, basically. HDDs are much slower when processing smaller files, since they have to seek. Remaining partition of the drives above, well now I know why I was having speed issues from this server now.
