Wouldn't this be a problem for writes then too?
I presume you would only compare read to write performance on a RAID5 device which has battery backed cache.
Without a battery backed cache (or pretending to have one) RAID5 write performance is abysmall no matter which alignment you use.
This not what's been reported we are seeing writes that are 2x the speed of reads. Give the additional overhead that writes encure on RAID5 this should never be the case. The results I go in my tests where: RAID5 ( 5 disk ) Read: ~50MB/s Write: ~140MB/s
Single Disk ( same controller ): Read: ~50MB/s Write: ~50MB/s
This just doesn't sit right with me something is seriously wrong.
