 Grant,
   I have no direct experience but I was asking some questions on this
 list recently. One disadvantage of software RAD would be that
 partition management tools like parted may not (or WILL not) do
 resizing on a software RAID but will (or should!) on hardware RAID. If
 you go with software RAID and later decide that a partition needs to
 be moved, resized, etc., then you may not be able to do it.

   I would suggest finding a good, if inexpensive, hardware RAID card
 or possibly play a bit with the RAID stuff on your motherboard to see
 if parted can work with it.

What makes motherboard RAID such crap?  I don't think I'll ever want
to resize partitions.  Mine are very simple root, boot, and swap and
I've never wanted to change them.  Is it slow, unreliable?

Motherboard RAID tends to be one of those things where corners are cut. It is 
not true RAID either in low-end boards - it is two drives that are always

form a *software* RAID, usually very limited in scope and usually very

One reason to be concerned about ANY software RAID solution would be
that when you boot something like a gparted CD to do some work you
won't necessarily have the right driver on the CD so you won't be able
to see the devices. A true hardware RAID card can (to the best of my
knowledge) always be accessed by the system. It may be slower if it
doesn't have special drivers to give you the best performance, but at
least it will work.

Just info and ideas.

That's largely true, but only while the drives are still in the same system. 
We are discussing the disgusting cheap crappy motherboard RAID out there, try 
swapping motherboards out on one of those and see what happens.

Tip: the motherboard does not believe the drives belong to it anymore.

At the other end of the spectrum we have the good quality hardware RAID, like 
what my manager insists we use at work (exclusively Dell). 100+ machines, 
history going back 5 years, no failures, no screwups, no data loss due to 
funky RAID. Plenty of drives failed though - the data center can get pretty 
hot (this is Africa after all).

So given the choice between crappy mb RAID and software RAID, I'm putting my 
money where the debugger lives - kernel-based sw RAID. If my boot CD does not 
support it, it's a trivial matter to fetch and burn another CD. Heck, I can 
go through the DC door and take my pick from whatever happens to be lying on 
5TB of assorted stuff on the ftp server. With an mb RAID gone south, I have 
no such options and run the serious risk of losing everything after hardware 
failure.

heat.


So you don't care about security, right? With security I mean redundancy 
 (RAID1,5,10,...)



Should I get another identical drive and set up RAID, or will
that create too much noise and heat?


A RAID won't cause more heat or noise than a second drive but it will 
also not necessarily solve your problem: RAID0 gives you the capacity of 
both drives combined and a lot of speed but if one of the disks dies, 
all data is lost. RAID1 spends the complete capacity of one of the 
drives for redundancy. RAID5 needs three drives (so it doesn't fit into 
your cost, noise and heat requirements), gives you the capacity of two 
and enough redundancy to loose one disk. However, its write performance 
isn't extremely high.



 Should I get rid of my current
drive and get a new drive, or will that not be much faster?


Your drive is good, why should you scrap it?


Velociraptors are reputed to be very fast, but $200 for 300GB is
pretty expensive and 1TB would require 4 drives which I think would
create a lot of noise and heat.



There are two brute force ways for an HDD to get faster: You increase 
their rpm or you increase their storage density (so that in one 
rotation, the r/w head can read/write more data). The latter has the 
advantage that it causes no additional heat or noise but more rpm give 
you lower access times.


I'd say if you don't care about redundancy, you should go for a single 
1TB disk. I'd prefer a Samsung Spinpoint F1. Spinpoints have the 
reputation of being a good mix between cost effectiveness, speed and noise.


Then I would use it (and the older disk) in an LVM volume group. LVM 
also supports mirroring (like RAID1) and striping (like RAID0) on a 
per-volume basis. That means that you could keep most of your data 
somewhere on the TB disk and still experiment with mirroring and 
striping using both disks for partitions which need more speed or more 
security.

LVM's support for mirroring and striping is exceptionally crude to say the

I don't find your criteria well-defined - fast, cheap (large)   
reliable, pick any two.


If the factors were ONLY cost, capacity, speed, noise, and heat, then  
I would say throw away your old hard-drive  RAID 0 across cheap 1TB  
drives, which are c £65 each at the moment.


In RAID 0, however, the 0 stands for how much data you get to keep in  
the event of drive failure, and most of us don't want that. I also  
don't see your old drive as redundant.


Haven't you considered just mounting an additional drive at /media/ 
video, or /var or /home or wherever?


I personally don't find hard-drives to be significant contributors to  
a system's noise. There are too many fans in any of my machines to  
notice the difference made by an extra disk crunching away.  
Additionally, in typical PC systems with capacity for only 4 (maybe 6,  
these days?) ATA drives, I don't find heat to be a problem. I'm sure  
I've read articles saying how heat is the biggest contributor to drive- 
failures, but I have two machines in my airing cupboard here [1], each  
stuffed as full of disks as possible (3 in one, 4 in the other PC) and  
have never had a failure on any of them. One system is at least 4  
years old, probably more like 6, the other at least a couple.


In a later post you say drive throughput may be an issue for you,  
which I did not really find clear initially. I would personally  
consider a pair of two of the cheapest new drives I could find  
(probably 80gig @ £22 each inc VAT or 160gig @ £28) and RAID 0 them.  
Others may advise if the partition scheme which immediately occurs to  
me - 3 partitions: swap, /tmp and /mnt/video/my_tmp - is wise. RAID 0  
will be twice as fast as any single drive, but for me I wouldn't need  
a large volume in that configuration, as I wouldn't keep anything  
important on it, nor the root of my system, nor anything that would  
need restoring in the event of a failure.


Stroller.




[1] US readers: I'm not sure if you use the same expression. In the UK  
the airing cupboard is the small cupboard in which the home's hot  
water tank sits. I guess you may keep the hot water tank in a large  
basement, but British homes have less room, so it is confined in a  
small cupboard which gets very warm indeed. Consequently it is used to  
dry bath towels after use, and hence the cupboard's name.

 What would be the benefit of using an external drive instead of an

It depends on what your needs are. Personally I use an external hard

I currently have two hard drives but had three until I got my DVD
burner.  Even when I had three drives in my case, I couldn't hear them
because of the CPU and other fans running.  I guess either my drives
were quiet or you may be water cooling or something.  I haven't had a
problem with drive noise in ages.

I do have a server case so heat has never been a issue for me.  Right
now my case temp is 73F, my CPU is 90.5F.  One hard drive is at 77F and
the other is at 84F.  The one running at 84F is the currently active one
with my OS.  The other is just sitting there spinning.

Hope that helps.

I painted the sides of my case with some of that rubber type of paint

side off, it can be a bit noisy but with it on, there is almost no

320GB drive and run RAID0 for speed and capacity.  If noise becomes a
problem I'll insulate as some have suggested.

My MSI motherboard supposedly has hardware RAID, but after Alan's
scathing evaluation of built-in hardware RAID offerings, I'm thinking
it might be crap.  It's just a $75 consumer motherboard.  Should I set
up software RAID0?  Am I getting into a(nother) big project?

On another system which must be about 10 years old, I'd like to
replace the IDE hard drive with a high capacity drive.  High-capacity
IDE drives are pretty much non-existent on newegg.com, but I'd like to
find one around 500GB.  Is moving that system over to the new drive as
simple as plugging it in, partitioning, formatting, copying, and
rebooting?

I forgot to ask, if the new drive is ATA100 and the old motherboard
can only do ATA33 or something, will they still work together?

 I'm pretty much out of space and I'm trying figure out the best way to
 expand.  The factors to consider are cost, capacity, speed, noise, and
 heat.
 RAID 0 will be twice as fast as any single drive

 I didn't realize that.  Maybe I should just buy another drive
 identical to mine and run RAID0.  That would be cheap, twice as fast,
 twice the capacity, and with some amount more heat and noise.  I have
 a separate backup system so I'm not worried about data loss.

Grant,
   I have no direct experience but I was asking some questions on this
list recently. One disadvantage of software RAD would be that
partition management tools like parted may not (or WILL not) do
resizing on a software RAID but will (or should!) on hardware RAID. If
you go with software RAID and later decide that a partition needs to
be moved, resized, etc., then you may not be able to do it.

   I would suggest finding a good, if inexpensive, hardware RAID card
or possibly play a bit with the RAID stuff on your motherboard to see
if parted can work with it.

   Just some thoughts.

Cheers,
Mark

Do not forget to install grub (or lilo) on the new disk. :-)
