1) RAID 5 has nothing to do with hot-swap. The unit itself does support hot-swapping drives, though. See the user guide at http://www.intel.com/support/motherboards/server/ss4000-e/sb/CS-022215.htm
2) The 'public' folder is just the default shared folder. See the above user guide for that, too.
3) Check http://www.intel.com/support/motherboards/server/ss4000-e/sb/CS-022212.htm for the list of hard drives that the NAS will recognize
Oke, I'm futher.
- Raid 0 and 1 seems to me no option to use it. In this situation you use the nas more as disk space but not for data protecting against loss.
- Raid5 seems to me the best solution. The data is protected agains lost and you have the most space available. If the NAS is not a week available because of 1 disk is corrupt is for me not such a problem.
- Raid5 + Spare is more or less the same as Raid 5 but this configuration must be used if you must deliver 24x7h support.
- Raid 10 I don't know in which situation this should be used.
- What I don't understand what kind of data should I put in this partition? Of become this partition only important when you use active directory authentication? And wherefore then?
- OR when you want to use FTP, is it only possible to access the public folder by FTP?
- AND is it then so, when you create user account, this user get also a part of the public partition like the home partition?
I don't think that it is the HDD but the 'electronics' around the harddisk. Because USB = USB seems to me? Or is the external HDD to big (500Gb)? I think I'm not the first one with such problem or....
Sorry, I like to understand why such a things work or doesn't work?
