Awesome Video!
Just built my FreeNAS box:
Pentium III 498MHz, 128MB Mem, **2TB RAID 5, Gb LAN (WoL), O/S FreeNAS on 4GB Compact Flash.
**Still waiting for the Drives to be delivered, but everything seems to be functioning.
‘Memory usage’ is only showing up as 34MB for some reason (Status>System).
I’m currently having a very hard time trying to find out how to create Partitions in a ‘RAID 5′ configuration though… Was hoping to have an Encrypted Partition.
I’m experimenting with the VM.

Great Tutorial! Looking forward to making my own RAID 5 NAS. Just Awesome.

can you do a video on how to setup authentication for CIFS/SMB ?
To make FreeNAS allowed to specific PCs on LAN.?
By the way, if you keep the authentication to anonymous… will freenas be wide open to the internet?

It doesn’t matter how many disks you use the formula remains the same. So for 6 x 2GB the total would be 10GB as you say.
You can’t add disks to an existing RAID5 setup. In version 0.7 of FreeNAS the ZFS file system is supported which allows storage pools extended.

Even if I use say… a lot more HDDs?
2GB x ( 6HDDs - 1 ) = 10GB
True?
Won’t it need more HDD or space if I build with more HDD?
Also, will I be able to add additional HDD to existing RAID5 setup? and still keep all the data on the existing RAID5 setup?
Future upgradeability?

The equation for RAID5 is simple:
Size of disk * (number of disks - 1)
So in your case it would be:
2 * 3 = 6GB
I hope this helps,

How much usable space would I get if I used 4 or more 2GB HDDs?
