What should I expect from a 8 drive raid 5 on 3ware 7500-8?
I get only
/dev/sda:
 Timing buffer-cache reads:   128 MB in  0.74 seconds =172.97 MB/sec
 Timing buffered disk reads:  64 MB in  1.55 seconds = 41.29 MB/sec

which seems to be slow compared to the numbers above

I think you should look at the '3ware bad write speed' thread on
linux-raid
looks like you are running in 3ware raid mode ?
