1. Utilized (6) 400 gigabyte sata hard drives.
2. Everything is on PCI-e (965 chipset & a 2port sata card)
Used the following 'optimizations' for all tests.
# Set read-ahead.
echo "Setting read-ahead to 64 MiB for /dev/md3"
blockdev --setra 65536 /dev/md3
That's actually 65k x 512byte blocks so 32MiB
Results are meaningless without a crucial detail - what was the chunk size used during array creation time? Otherwise interesting test :)Indeed, the chunk size used was 256 KiB for all tests.
