Yup.. Kind of no point in having RAID 5 if it is not reliable to rebuild...

Correct. David correct if I am wrong here please...

Mine is;
-04 model of the 4000
v3.4.805 OS (will probably up to the 3.4.807 for any bug fixes possible)
Hardware 2.0.1
BIOS 2.0.282

The very drives I have wanted to use, but too costly for me to experiement...

This the very thing that has been bothering David and I. That RAID 5 should not have taken that long to build. With 4x250 drives it would have been a MUCH shorter time and yet not that much smaller drives. David, you got any ideas? It all seems to work, but this time thing indicates "something" not right (at least to me).

2a. Interestingly, View Disk Status reports the RAID5 - Large data protection disk at Total<MB>=898,211 Free<MB>897,313 which seems to be lower (876GB)

You don't divide by 1024 each time... 1024 bytes = 1KB but 1000KB = 1MB and 1000MB = 1GB (at least that is what I was taught). You do have to divide by 1024 once in that sequence, but only once. Anyone disagree?

Hold up there buckaroo. One big file will not give a good test. You need lots of files, large, small, and everything in between for a proper test (and multiple subdirectories as well).
THANK YOU for taking the time to test this all out! It should help you, me, and everyone else down the line when these type questions come up. It sure helps to know that the damn thing is going to work as it should with these larger drives.
I am still puzzled with this amount of time it is taking to create the RAID array. David? Anyone? Ideas?
