It's Byte, so 66 Megabytes/sec is correct.
But that's just the burst rate. If you look at the specs
for the disk drives, you'll see that they can't keep up with that rate.
I figure anything 10MB/s sustained is pretty good for todays drives.
Expect more in the future.

Hi,
WD tech support is wrong. Ultra-ATA/66 is definitely 66 megabytes per second.
Not 66 megabits. There is ABSOLUTELY NO QUESTION about this.

it as an aggregate from multiple drive transfers on the same

I didn't try 4 drives. 19MB/s doesn't sound too impressive for 4
drives at raid5.
How are you measuring the performance?
I've found that reading /dev/md0 is quite a bit slower
than reading a file on a mounted filesystem on /dev/md0.
Well, true, I got 19MB/s when I did a "hdparm -t
