You can sometimes get the same effect at the post screen, by installing a cpu the bios doesnt correctly identify. I used to have a PIII-650 in an oem BX chipset board which the bios identified as a "Pentium MMX 98mhz".

And with my apparent 1.8 million percent overclock, I've only noticed about one more degree celcius in idle CPU temp.

*bump*

Ok. I'm kinda thinking that I should add some data storage redundancy to Orpheon, now. I've still got the original two Western Digital WD2500KS hard drives running in RAID 0, and with a couple hundred gigs of data in there, I'm worried about losing it all to a drive failure. These drives are set to never spin down, and this computer stays powered on 24/7. It's been running almost non-stop for a year and a half, now, and while I don't really have reason to believe that either of the hard drives are anywhere close to failure, I don't want to even remotely risk losing all of my data. (I've been risking it since I built the computer, really.)

Anyways, newegg.com still has the WD2500KS in stock (and cheaper now). My question is: How difficult would it be to buy two more of those and add them to my current RAID 0 setup to create a RAID 0+1 setup? Are there any special proceedures, or can I just screw them in and plug them up? Will I have to manually copy all the data over, or will it automatically be copied?

Any help would greatly be appreciated.

Hard drives are generally not much more prone to failure due to being on all the time, except very early and very late in their life spans.

If your RAID controller is vaguely intelligent, you should be able to convert from a RAID 0 to RAID 0+1 with minimal fuss. How difficult it is depends entirely on your RAID controller.

RAID 0+1 works well, but i wouldnt count on it as your only form of backup (for the reason's i outline here).

I'd be more inclined to look into a single large drive, either in an external enclosure, or some form of nas/file server. Ideally you should also keep another copy (of at least your most critical data) offsite, either on HDD or optical media.

I don't think you can change a filesystem that's been established. I also don't think your Raid controller will like drives that aren't identical if you are going to have them in an array.

With linux, you can trick the OS into thinking the drives are identical by fudging the partition tables a bit. With "Hardware" (no raid is really hardware) it's a little more twitchy.

I think Raid 0 is plenty reliable. Just never run out of space and make sure you have a backup. A "disk full" will reveal any problems with your config usually damaging the filesystem. I use a vantec hotswap rail with a 250 GB backup drive to save important stuff.

If you do have a filesystem problem, you'll be screwed, but I've been using this 80GB X 4 Raid 0 for a year with no hassle. Geez is it fast.

This would have been a problem in the past, but the stack of obsolete... never failed.... hard drives I have on the shelf here shows me the technology is pretty bullet proof.

Back in the early 90s, drives only lasted 3 years. Now days, I think they're pretty bulletproof.

Well, it's an MSI K8N Neo4 Platinum motherboard with an Nforce 4 chipset. I haven't checked to see if there have been any updates to the BIOS or RAID software since I built it in 2005. :P I believe the controller is a Silicon Image SiI 3114 SoftRaid 5. Other than that, I don't know much about it.

I'd thought about getting a large external hard drive, but I saw that it wouldn't be economically unfeasible to just buy a couple more identical drives and add them to my RAID array. I just don't know how difficult it'll be to set it up, yet. Of course, installing the drives is the easy part. Slide 'em in, screw them down, and plug them up. I figured that since everything is SATA, it wouldn't be too much of an issue, but if the RAID controller is going to be inhibitive, then I'll find another route. I wouldn't mind making backups on blank DVDs, but I'd be burning for hours.

The ones that I would be buying are identical to the ones that I already have. Newegg still has them in stock, and they're a great price now.

I just bought a Vantec hot swap rail for backups. Stick a drive in there.

These are 40 bucks, make your computer look cooler, and you can just use whatever SATA hard disk you can get on sale.

Vantec SATA EZ-Swap Removable Hard Drive Rack

These have a built in thermometer and fan, so it helps cooling too.

I have these in a couple of my machines. That way I can move big data around fast. It's nice to be able to do things like put your whole music collection on the "other" box.

Until we can use BlueRay for a backup

Look at the Vantec Nexstar3 or if you have an old EIDE drive the Nexstar2. I have an old 160GB IDE drive in a Nexstar2. It is quite a bit slower than the SATA hot swap, but it beats the crap out of burning DVDs

These are the only external drive enclosures that I ever found that were 100% cool!. They look really good, and they work perfect.

Having good backup devices sure saves a lot of hair pulling.

If I get one of those, I'll definitely have to run an SATA cable through the back of my computer case. This motherboard (even though the specs specifically stated that it had USB 2.0 HiSpeed support) doesn't have USB HiSpeed. I can't tell you how pissed I was when I found that out. >:[ If I'm limited to using a USB connection, then I might as well burn my backups onto DVDs because that would be faster.

Get an external SATA card. $20 or so. You didn't want to use USB anyway. I haven't played with this, but I guess the speed on these external units is about 30 Gbps. That should be fast enough that you probably couldn't tell it wasn't just another hard disk.

Unfortunately, there's no more room for any more expansion cards, either. If I remove one of the slot fans, then my crappy heatsink-only video card will start getting hot and won't perform as well. If I can find a way to fit it in there, though, I'll keep that in mind.

Look for a compamy called "Artic Cooling". They sell video card coolers that won't take up any more room than a slot. They're a custom fit for most Nvidia and ATI cards.

$25 or so I think.

I've been doing a bit more thinking about this. I'd still really like to get two more identical drives and convert my system from RAID 0 to RAID 0+1 if at all possible, but if it's not possible, I'd be willing to get an external enclosure with a single large drive. If I can turn my system into a RAID 0+1, then I'd be getting two more of these hard drives. If I have to get an external enclosure, then I'll be getting one of these drives for it. I'm still looking around at external enclosures as well.

My motherboard is an MSI K8N Neo4 Platinum, and if I'm not mistaken, it's got two RAID controllers onboard (total of 8 SATA ports). One is listed as an nVidia Nforce4 Class RAID Controller, and the other is a Silicon Image SiI 3114 SoftRaid 5 Controller. I don't remember exactly how I set this thing up, but Everest is showing my hard drives as "NVIDIA STRIPE 465.77G (465 GB)"... So I'll just assume that it's using the Nforce4 RAID controller. I did a little bit of Googling to find out some information about these things, but I didn't turn up much. Does anyone know much about these controllers and whether or not I'll be able to do what I'm hoping I can?

According to the motherboard manufacturor's website, those are "software RAID controllers". I suggest installing the software for them and seeing what options it gives you for converting RAID pools.

I know I installed the RAID controllers when I built the computer, but that was a year and a half ago. I'll reboot it here in a little bit and see if I can access the RAID controller setup to find out what options it has.

I rebooted a little bit ago and got into the RAID config. It looks pretty simple, but it might let me add a couple more drives to it. I guess I won't really know until I install them, huh?

Well, technically, very nearly everything in a modern computer is "software", given that definition.

What are you doing that needs all that speed?. I did Raid 0 so I could I could handle uncompressed video in real time.

I have to admit though Quake 4 levels load fast! and I can suck up a DVD-9 in 5 minutes, actually 2 at once.

Believe it or not, my setup isn't really much faster than just having a single drive hooked up normally. If I had four or more drives hooked up in RAID 0, then it'd probably be a lot faster. I mainly set it up this way because I wanted a single large 450+ GB partition to store all of my data on (largest drives available when I built this computer were 400 GB, and they were expensive then).
