Raid 0 Array

[beastmaster]

When I bought my PC 7 years ago, I asked the techs to create a Raid 0 array with my 2 200GB WD drives. Recently, I have been reading the comments here and on other forums to stay away from Raid arrays as they are more problems then they are worth.

What I want to know is what is the best way, and procedure to accomplish this, to remove this Raid 0 array and use my 2 200GB SATA drives as separate drives with the OS on one and data on the other. I will probably partition the OS one as I do not need 200GB for Windows 7.

Am I correct in assuming that once this RAID 0 array is broken, I will lose everything and will have to do a clean install of Windows 7 plus all my apps?

thanks

Backup all of your data, make sure that you have backed up all of your data. Remove the array configuration, get out your Windows DVD, reinstall the OS, patches, and all applications, copy your data back from your backup.

Yes, a Raid array can give you problems and it increases the risk of loosing everything. But if it worked for 7 years, I would guess it will be OK for a bit more time.

But if you decide to go without it, I suggest to use the second HDD for images so that you have a good backup.

Thanks, I will be storing all my backup images on the second drive for sure.

When I boot up, I see a screen that allows you to configure or view the array. I believe I have to press CTRL + I or something like that to get into it. Do I remove the array there or change a setting in the BIOS or both?

Also, can someone recommend a good external USB hard drive under $100.00? I do not want any preinstalled software like there is on the WD My Book Essentials.

One further question, if I use Windows 7 backup image as I usually do and backup my "C" drive to an external source before I remove the array, can I just restore that image to one of the drives after the array is gone?

I can't answer about the raid image as I have never used raid, but I would seriously doubt it.

As far as the external hard drive, the best way is to make your own. There is a thread on making your own hard drive that can give you some good ideas. I have several, but like this one best. The advantage is you can use it however you want and change out drives whenever you choose.

1. I think you just need to remove the array.

2. Here is a website where you can find external disks at good prices: Storage Devices Deals - Deals2buy.com You should also check the last entries of this thread: http://www.sevenforums.com/chillout-room/75383-best-deals-day.html

3. I do not think you can restore an array image to a single disk - but you can always try.

You would definitely need to break the array, which means losing everything on the drives. You'd want to have everything backed up first. Then, you'd disable RAID, setting the drives up as standard drives, and then do a fresh install as normal.

That's the issue with RAID0. If you lose a drive, all the data on all drives is lost. Had it been a mirrored array, you could technically pull one drive out and still boot, bu that would defeat the purpose of running any type of array in the first place.

Also, with the external drives, don't worry about the programs they put on them. A reformat will usually get rid of them. Most of them are a waste anyway.

Been reading horror stories about WD MyBook Smartware software. I will not be getting anything from WD until that stuff is totally removed. I do not require any software on the external drive as I already have all necessary software and what I would need Windows 7 has. I just want to plug the drive into a USB port, be able to see it under Windows Explorer and use it like any USB device, by copying and moving files from one drive to another. I would create a partition on it and store my System Image backups made from Windows 7 Backup, on it. I am looking into the Enclosures now and going to check with my brother to see what sizes of hard drives he may have laying around. If I have to buy an internal drive I will check those out as well. It appears to be much cheaper to build your own rather then buying one of those external units like WD MyBook, etc.

It is and much more flexible.

this forum is very very helpful...

i recently bought a MSI i5 500G GT780 laptop.. dual HDD raid0 capable..

the thought i am having these past few week is to buy another 500G HDD and enable raid0 (which will make the 2HDD as one, right?)... this is the first time i have encountered the word "RAID"...

due to risk, i am only adding the 500G as additional storage capacity...

What are you trying to accomplish - speed, data security ?? Raid is usually not advised. You may be better off with other options.

 

[sweetnightmare]

i mean, im not trying to accomplish anything.. just a bit curios of RAID though... thanks

Hmm, if you have no objective other than experimenting, go ahead. Make sure you have a good image of your system and your data because chances to screw it up are high.

In these days of SSDs, Raid is not very popular any more because the performance gain is relatively minimal. A SSD outperforms a Raid configuration 10 times. And even for mirroring it is not the best solution for a desktop. Imaging is a better deal. For servers it still has a function though.

If I had your laptop, I would use the second bay for a 60GB SSD and put the OS on that. Then you get a BIG performance boost. 60GB SSDs can be bought for under $100.

 

[sweetnightmare]

ah,i see...

define performance boost for SSD?? what part will it affects? (boot-up, etc)..

i am definitely taking raid already... im more into expanding the storage of may laptop.. im more of a gamer...

 

[sweetnightmare]

erratum: i am definitely NOT going to RAID option..

SSD performance is in all system areas. Boot times around 15 seconds, calling programs is instant - even big programs and the whole system is just snappier.

The access time to date on the SSD is about 150 times faster than to a HDD and random 4K reads (which the system does over 50% of the time) is up to 10 times faster. There is just no alternative to a SSD for top system performance.

However, the SSD is no help when you access the internet. That is more of a function of the line speed. It also does not help in cases where you need a muscular GPU.

I am a bit amazed that you want to game with a laptop. Laptops are usually not good at games because of their weak graphics.

 

[sweetnightmare]

i did want a desktop for gaming...

but due to the fact i am currently working with no permanent address (just renting an apartment), i want to be mobile all the time.. thats why i bought this MSI GT780 gaming laptop.. im really not that hardcore gaming..perfect world is my main game.. seconday are the first-person shooters...

thanks though for the inputs...

Cough, Falcon DRX, cough. You can get good gaming laptops... provided you're willing to pay for the privilege.

As for experimenting with RAID, reading up the wiki entries and then following up the links would be more educational rather than a "hands on" test with your own hardware.

You can put as much money as you want into a gaming laptop, it will never match a desktop for the same money. Simple problem is heat that is produced by the GPUs and cannot be properly handled in a laptop. Therefore it will always be a foul compromise.
