I am thinking of retiring my server, and building a much more power
efficient, slim HTPC/server, and putting all of my data on one of those
Drobo things.

I am also considering the Netgear ReadyNAS Duo.

Major hit to write performance.

Not noticable to me through network, and of no significance, as this a
network stored data. Read performance is more important.
Doubles the cost of storage.

Of little significance, as drive capacity/price has grown so much faster
than the size of my files.
Gives a false sense of security.

What am I worried about? It's a lot more convienent. What is all this fear
about?

What do you suggest I do instead?

You are already doing what you want to do. But, it is not for everybody and
can give a false sense of security.

Backup imaging trumps raid in my book - for the home user.
 
Are you some sort of anti-RAID fascist or soemthing? =P

No, raid's fine for increasing reliability, providing large
chunks of storage, and increasing throughput in certain situations.
But it's not backup.
 
Thank you for your concern, but I am very happy using RAID-1 in case of
drive failure. It has saved me twice in the last three or four years,
when a drive has failed. There is no effort involved, and I see no reason
to *not* use RAID-1 for my data drives. Drives are cheap enough these
days, and have such high capacities, that I only need two pairs to put all
my valuable data on. I do not bother doing this for media drives.

As I said before, I also do other things, like I keep my irreplaceable
files backed up on a remote server, owned by a friend, and I also have
automated scheduled True Image Echo Workstation backups done through
network, for my desktop machines, and laptop (through wifi). Only a tiny
agent needs to be installed on them, not the full program. The server can
even push the agent onto the clients. I have very little worry about loss
of any important data, which my living depends on.

As long as you are not relying on it for backup, I don't have an objection
to what you you are doing. If it works for you, that's fine. Note my
sentence above, quoted from my previous message: "If you are using RAID1 as
an alternative to backup, let me recommend that you do *not* do this." The
main reason I replied to you at all is that most people who use RAID1 in a
non-corporate situation mistakenly think that it's a form of backup and a
good way to achieve this.

And as far as it only being used in corporations, heh, I know many people
that use RAID-1 or 5,

I do too. I don't claim that it's only used in corporations. My point is
that is *is* sometimes used outside of corporations, and as a substitute for
backup, Thta's what I was recommending against



with things like FreeNAS or in dedicated NAS
