Didn't require any special drivers for the OS - it just looked like a
regular IDE device. But could quite well be something to do with the
You'll be unsurprised to hear that he quickly threw it away...
I understand that Linux can do software RAID if you have the right
kernel. Some versions of Windows can too - but IIRC not the desktop
editions? It's not something I've ever really looked at. For me, RAID is
something you only need on mission-critical servers, not desktop
machines and certainly not home PCs. ;-)

That's the killer. At least the Windows software RAID-1 only copies the
used blocks.

You're gaining a disk that's nowhere near the machine when the rain
comes in the roof and floods your office. :-)

Videos
Music
Podcasts
Webcasts
Documents (including large pdfs)
Installation files
Client DB performance data and documents
Backups of data on desktop and laptop
Virtual machine hard drives
It also runs the following:
Active Directory
DNS
SQL Server 2005
Oracle 9i (currently shut down)
Windows Sharepoint (pending reinstallation)
In addition, I'm trying to set up a media service so that the XBox can
stream video and audio from the server.
It's got 480 GB of drive space on the RAID array and it's over half used.
I'll upgrade the drive space sometime, but it's not going to be a simple
operation
My desktop has one 320 GB, one 160 GB and one 80 GB drives.

Indeed. Probably makes it much faster...
Personally, I've never really trusted software RAID. I always prefer a
hardware solution. (But, obviously, those are very expensive. The ones
that work properly, that is...)

If *my* office ever _floods_... Well, let's just say I have way bigger
problems than some binary data on a computer. ;-)
(My house is at the top of a hill, and my office is on the 2nd floor.)

(I have a server at work that's rather full with Ghost images.)
Podcasts and webcasts are (AFAIK) designed to be small so they download
fast.

OOC, what does that actually *do*?

The VMs aren't too bad. I don't have too many and I use a differencing drive
method of creating them The os and common apps only exists in one virtual
drive, but can be used by multiple VMs. When I install something into one of
the VMs, all that gets stored is the differences from the base image.

I've got everything from 10 min interviews up to 2 hour conference sessions.
Got a couple of GB in total. More on DVD.

It's a glorified web portal with a million addons. There's a lot of demand
for it at the moment in SA, so it's mainly there so I can get some feel for
how it works.

When I installed Linux (Ubuntu), I didn't separate /home into a second
partition. Stupid me. Now I want to switch distro, and I know it won't be
such an easy task...

Or for a little more (I think they're like 140 pounds now) you can get a
blu-ray writer. Those discs take 50GB each if you get the dual layer ones.

Really? I knew BluRay was higher capacity, but I didn't know it was
quite that much...
