I have 2 IDE disks, each as master on their own channel.
One is significantly faster than the other, benchmarking
scores of 15-20 on sequential in tiobench, while the other
is in the 5-9 range.
tiobench on a 2 GB, 16k chunk RAID0 set shows some interesting
info:
the sequential speeds are about the average of the two disks.
the random speeds are about the SUM of the two disks' speeds.
As I increase the block size in tiobench, the sequential numbers
drop slightly, but the random numbers increase nicely, up to
about 3-4 MB/sec with a 32k block size.
Q: Is the limp sequential performance due to 1 disk being
significantly slower?
Q: Any pointers on what a "good" chunk size is, if say,
I have many many 4kb files? 2k?
