I'm building a new system (X58 chipset with an i7Core) and want to get into RAID.

I think that this is a decent controller for me - HighPoint RocketRAID2310 PCI Express x4 ~$145.00 US
I'd like to pair it with the Western Digital VelociRaptors.

Some questions:
- If I were to RAID with only 2 drives (RAID 0 - I think), is there any way to back the array up so I can restore it later on (in case of a drive failure). If not, is there any other alternative out there? I'm trying to save a bit of money - and buying 2 instead of 4 of them will help.
- I'll be storing all data on another drive, so that won't be a factor.
- The RAID array will have the OS and all the Program Files (I don't do movies or music).

Any other comments/suggestions for a RAID n00b?

TIA!

I would suggest a RAID 5, rather than a naked RAID 0....but that suggestion is based on having backup of the RAID 0.

If backing up is not a problem...and this system is just going to be a gaming system...then I can see going with a naked RAID 0.

That's the only scenario I can see going with it :thumbsup:.

Not a gaming system - but it's gonna be my primary system for the Windows 7 beta when it debuts
I'll only have some Windows tools, some Virtual Machines, and my bookmarks on it (OK, and a couple of games also! :thumbsup:

I'm not worried about restoring the RAID0 info (if I can restore an Acronis True Image backup to the RAID array (still researching this))
But am worried about $200 a drive - so RAID 5 would cost me $800 just for hard drives.

Another question also. In my current system I've got my pagefile on another hard drive - would this be possible/advisable/advantageous on a RAID array?

Hmmm...I've never believed that moving the pagefile did anything worthwhile doing, I've never concerned myself with how fast paging operations take place, when they take place, or why they take place...since RAM became a more reasonable commodity to purchase.

Honestly speaking...I think all of the old advice about moving the pagefile...stems from Win 95/Win 98 days when the systems that we have today were not even envisioned. I just let XP manage it and everything seems to work satisfactorily for me.

You are in a different category than I am and I would imagine that nanoseconds count in your world, whereas seconds don't even count in mine :thumbsup:. The pay is not good for retirees, but the free time is one heck of what others would call "a blessing."

I know what you mean about the hard drive cost, but...

While showering this morning, I was reflecting on just how much is a reasonable expenditure per year for a computer system...for a person living on a fixed income (that is meager) like me. I reasoned thus:

a. My computers (I have two) are a daily necessity in 2009, they are a hobby which is also a necessity for just about anyone who doesn't live in a cave today. And I bet that some of those who DO live in caves have laptops :flowers:. A computer is more valuable in many ways than a car...and I have no problem at all with spending $1,000 a year on the upkeep of my car for maintenance and repairs because I consider it vital to my life.

That $1,000 does not include insurance, taxes, or gas...strictly maintenance needed to be operational.

b. If I'm willing to spend $1,000 a year on that...then I ought to be willing to spend at least that much on my computer system, based on its value in my life experiences. I use it for all sorts of "business" purposes, but it's value accrues to the way I use it.

I shop (for everything other than food), I inform myself about necessary events/details, I watch/record TV, I buy/collect/play music, I establish/maintain contact with others whose knowledge and good spirit enhance my life, I communicate with those close to me, and I educate myself somewhat (gathering more knowledge about more things each day of my life).

Sooo...IMO, having a computer system running is worth an expenditure of $1,000 a year (I don't think I spend that but I should without regret).

OTOH, you are still working and any computer you own contributes in some way to your capabilities in your chosen line of work (now). You have more income and more mouths to feed than I. You probably expend a lot more than I, of necessity.

If I use that $1,000 figure as a percentage of my incoming cash flow...I come up with 2 different numbers (because I will increase my incoming cash flow via Social Security in 2 months. Percentagewise, about 8% today, about 4% in 2 months.

So my guidance to anyone like us (who truly use our computers for some of the many varied capabilities) would be to spend anything between 4-8% without even questioning it...on your system(s).

Of course, the wife may not like that but that percentage doesn't seem like a heck of a lot to spend for the benefits which a system confers on those who truly use it.

If a gamer can spend $200 on a video card which will be obsolete and kicked to the curb inside of a year...I don't think $800 for hard drives is excessive at all, considering that (IME) it's fairly rare when a drive goes bad and becomes totally useless.

I'm sure that others have opinions on this, let's see what they say :trumpet:.

With the pay increase for a Global Mod. It will seem like pennies :thumbsup:

I never had a reason to look into Raid, but reading up on it there seems to be varying opinions. Still looking for a good explanation

Wikipedia seems to have a good rundown: http://en.wikipedia.org/wiki/Redundant_arr...dependent_disks

Other links I had saved which refer to RAID (probably outdated somewhat):

RAID Tutorial & Benchmarking Tools - http://www.raid.com/04_00.html

Admin's RAID Data Recovery Guide - http://www.raidrecoveryguide.com/

Basics of RAID - http://ezinearticles.com/?Basics-of-RAID&id=11919

Well, I bit the bullet and got the 4 hard drives. Ordered it all just a little while ago, and should have it by the weekend!

Thanks Louis! I'll post back with "trials and tribulations" once/if it's running!

It took longer to read the instructions than to set the RAID array up (about 30 seconds)
It took Windows Vista about 20 minutes to install to the point where I could reach my Desktop
Installed RAID drivers off of a flash drive (floppy NOT required)
The driver installation took about twice as long as the OS install.

Vista Experience score of 5.9 across the board!

Still downloading SP1
Then will update drivers
Install SP1

Then install the Win7 beta on the other partition
If it works, then I'll start using it.

If it fails, then I'll try the upgrade install on the Vista SP1 install.

Once I'm transferred over to Win7 fully, then I'll do the upgrade install anyway.

The performance increase with RAID 5 is dramatic. It's worth it (to me) with the added investment in a hardware RAID card and the extra hard drives.

Thanks all for your help here!
