I would prefer to have each drive seperate, so if 1 drive goes south on you, you only loose the data on 1 drive.

Don, the settings for the drive on the Iomega allow you to set the drive up as Raid 0,1 or None. The problem is that you loose 1/2 the drive space on Raid 1 as they are mirrored. Raid 0 you will get a little better performance but you loose a portion of the drive space. None allows you the full space on the 2 tb system, again if one drive goes you loose all the data, and you loose a bit of performance.

In the box there are 2 1 tb drives Raid 1 is the safest but the cost of loosing 1/2 the hard drive space, see he needs to decide on weather or not he wants the full 2 tb, but if one drive goes south all the data is gone from what I understand and yet with the raid 1 if one drive goes he can replace the drive and it should rebuild. I was looking into this same thing this afternoon and found Raid 1 is the only way to protect your data, Raid 0 and none you loose the data.

I had changed mine to none to get all the hard drive space, and hope that there is no issues, but just in case I have all my stuff I don't want to loose on the homeserver.

Raid 0 puts a strip on the disk, permitting you to almost double up the size of the disks,(minus the stripe)
Raid none is like a JBOD set up???

Yes having it set to None is JBOD Don, which in the case of the Iomega may just be fine for Tom. Setting it to Raid you loose a ton of space and if he backs up the important files he should be fine.
