Funny, we tried this yesterday ...
You can use 26 disks (750GB disk => about 650GB usable ...) Raidsize doesn't matter ! So if you use raidsize 3 you'll have less than 6TB for data ...

As far as I know, the 16Tb limit is the raw limit for your aggregate. 16Tb / 750Gb = 21 disks.
Using 14 disk raid groups, you will have 4 parity disks for 2 RAID groups, meaning, you will have 17 data disks in your aggregate.

We're going to buy some shelves of 750G ATA drives. An aggregate is limited to 16T "raw" (which I presume includes parity disks). Not having any 750G drives yet, we don't know what they size down to. Can anyone tell us how many 750G disks (including parity) that you can stuff into an aggregate?
