Raid 0

When Installing 2 drives in raid 0 I always have to reformat right or can I image the drive?

 

RAID 0 stripes your drives. therefore, data isn't store in one piece, but split into segments and stored on separate drives. ergo, you must reformat.

 

What do you mean by "image"? Copying an existing install rather than installing from scratch, using something like Clonezilla?

As long as you have software that can access the logical drive after the RAID drivers are installed / activated, you certainly can perform operations on it as if it weren't a RAID drive at all.

 

Don't bother with Raid 0 if you haven't added the second drive. Just run two separate drives.

 

I already bought them and I would not buy them If I wasn't going with raid 0

 

I have 2 320GB drives in my desktop as well but I haven't done Raid 0. Some facts...

- Unless you have a Raid controller, you probably aren't going to see any performance increases in Raid 0
- Raid 0 means double the chance of losing all your data as if one drive fails, all of your data is gone.

Anyways... You could just put media and stuff on one drive and keep games and the OS on the other drive. Your choice in the end. If you do go Raid 0 tell us how it goes.

 

Well same thing goes if you have 1 drive.

 

i don't quite understand that, Mike.

 

Well Stone is saying having raid 0 if 1 drive fails you loose all data. I am saying same thing goes if You only have 1 drive

 

yeah but with raid 0, you have two drives that can fail. if you have only one (physical) drive, the chance of having a drive fail is halved.

 

I have never had a drive fail If it does fail I don't mind paying another drive I have nothing important on my M17 just junk and games.

 

hey, it's your call. just don't complain when it does happen

 

It wont

 

Do it, Mike. You'll have approx. double the performance of a single drive. This is purely for data transfer though. It's not gonna net you crap as far as 3DMark scores go.

 

Yeah I know thats why am getting it for the performance not the 3D06 scores.


Thanks for everyone's help

 

Two 320 gb 7200's in RAID 0. Should be beastly Post hdtune results!

 

Installing any application/game takes no time at all. GTA IV, for some reason, still takes 4 1/2 hours to install though. Congrats on the rig, it is getting quite beastly. I'm gonna have to get that Quad X9300 now

 

I wont be getting the X9300 until applications start using the Quads.

Yeah my HDD arrive tomorrow so as soon as I get them all do the HDtune test

 

I have my HD Tune results posted in either my benchmarks thread or my review thread, can't remember. But that's for 160GB RAID0. Remember to enable RAID0 in the BIOS. That part threw me for a good bit. BTW, I'm not really getting the Quad. The ES is nearly $900. And besides that, my wife will REDRUM me.

 

Ok once I install the two drives I go to bios turn on Raid 0 then how do I go to the Intel manager for setting up raid 0?

 

The performance isn't going to be double. I have a ton of work but Ill post some benchmarks. They found that the performance increase wasn't anywhere close to what they thought it would be.

 

Actually its just 5-6% increase in performance

 

Hmmm. Maybe I should have been more specific. My read/write times versus a single 160GB drive were nearly double, aside of the access time. Don't know what the actual system performance impact would be.

Mine:

i got raid 0 on my rig, will post the results for it when i get it

 

RAID — which stands for Redundant Array of Independent Disks [1], or sometimes alternatively Redundant Array of Inexpensive Disks — is a technology that employs the simultaneous use of two or more hard disk drives to achieve greater levels of performance, reliability, and/or larger data volume sizes.

"RAID" is now used as an umbrella term for computer data storage schemes that can divide and replicate data among multiple hard disk drives. RAID's various designs all involve two key design goals: increased data reliability and increased input/output performance. When several physical disks are set up to use RAID technology, they are said to be in a RAID array. This array distributes data across several disks, but the array is seen by the computer user and operating system as one single disk. RAID can be set up to serve several different purposes.
Contents

Purpose and basics

Redundancy is a way that extra data is written across the array, which are organized so that the failure of one (sometimes more) disks in the array will not result in loss of data. A failed disk may be replaced by a new one, and the data on it reconstructed from the remaining data and the extra data. A redundant array allows less data to be stored. For instance, a 2-disk RAID 1 array loses half of the total capacity that would have otherwise been available using both disks independently, and a RAID 5 array with several disks loses the capacity of one disk. Other RAID level arrays are arranged so that they are faster to write to and read from than a single disk.

There are various combinations of these approaches giving different trade-offs of protection against data loss, capacity, and speed. RAID levels 0, 1, and 5 are the most commonly found, and cover most requirements.

* RAID 0 (striped disks) distributes data across several disks in a way that gives improved speed and full capacity, but all data on all disks will be lost if any one disk fails.

* RAID 1 (mirrored settings/disks) could be described as a real-time backup solution. Two (or more) disks each store exactly the same data, at the same time, and at all times. Data is not lost as long as one disk survives. Total capacity of the array is simply the capacity of one disk. At any given instant, each disk in the array is simply identical to every other disk in the array.

* RAID 5 (striped disks with parity) combines three or more disks in a way that protects data against loss of any one disk; the storage capacity of the array is reduced by one disk.

* RAID 6 (striped disks with dual parity) (less common) can recover from the loss of two disks.

* RAID 10 (or 1+0) uses both striping and mirroring. "01" or "0+1" is sometimes distinguished from "10" or "1+0": you could conceivably have either a striped set of mirrored subsets, or, a mirrored set of striped subsets.

RAID can involve significant computation when reading and writing information. With traditional "real" RAID hardware, a separate controller does this computation. In other cases the operating system or simpler and less expensive controllers require the host computer's processor to do the computing, which reduces the computer's performance on processor-intensive tasks (see "Software RAID" and "Fake RAID" below). Simpler RAID controllers may provide only levels 0 and 1, which require less processing.

RAID systems with redundancy continue working without interruption when one, or sometimes more, disks of the array fail, although they are vulnerable to further failures. When the bad disk is replaced by a new one the array is rebuilt while the system continues to operate normally. Some systems have to be shut down when removing or adding a drive; others support hot swapping, allowing drives to be replaced without powering down. RAID with hot-swap drives is often used in high availability systems, where it is important that the system keeps running as much of the time as possible.

RAID is not a good alternative to backing up data. Data may become damaged or destroyed without harm to the drive(s) on which they are stored. For example, part of the data may be overwritten by a system malfunction; a file may be damaged or deleted by user error or malice and not noticed for days or weeks; and of course the entire array is at risk of catastrophes such as theft, flood, and fire.

Principles

RAID combines two or more physical hard disks into a single logical unit by using either special hardware or software. Hardware solutions often are designed to present themselves to the attached system as a single hard drive, and the operating system is unaware of the technical workings. Software solutions are typically implemented in the operating system, and again would present the RAID drive as a single drive to applications.

There are three key concepts in RAID: mirroring, the copying of data to more than one disk; striping, the splitting of data across more than one disk; and error correction, where redundant data is stored to allow problems to be detected and possibly fixed (known as fault tolerance). Different RAID levels use one or more of these techniques, depending on the system requirements. The main aims of using RAID are to improve reliability, important for protecting information that is critical to a business, for example a database of customer orders; or to improve speed, for example a system that delivers video on demand TV programs to many viewers.

The configuration affects reliability and performance in different ways. The problem with using more disks is that it is more likely that one will go wrong, but by using error checking the total system can be made more reliable by being able to survive and repair the failure. Basic mirroring can speed up reading data as a system can read different data from both the disks, but it may be slow for writing if the configuration requires that both disks must confirm that the data is correctly written. Striping is often used for performance, where it allows sequences of data to be read from multiple disks at the same time. Error checking typically will slow the system down as data needs to be read from several places and compared. The design of RAID systems is therefore a compromise and understanding the requirements of a system is important. Modern disk arrays typically provide the facility to select the appropriate RAID configuration. PC Format Magazine claims that "in all our real-world tests, the difference between the single drive performance and the dual-drive RAID 0 striped setup was virtually non-existent. And in fact, the single drive was ever-so-slightly faster than the other setups, including the RAID 5 system that we'd hoped would offer the perfect combination of performance and data redundancy"[2].

 

JellyBeans and Mike2011. Be aware that your accounts will be permanently banned if you continue your childish squabbles or insult any other members.

 

jeez, people. can you not make reasonable, objective posts?

EDIT: thanks Budding.

 

Did I miss something?

Mike didn't say anything derogatory, and Jellybeans hasn't posted anything in this thread.

Were some posts removed due to content?

 

Probably.

I noticed the same thing. The derogatory posts were probably removed.

 

They were, I was following this thread. My post asking for a ceasefire so we could utilize the thread properly was also removed

 

He started insulting me so I insulted him back basically

 

Meh, that dude is hateful. You got the X9100 and the RAID0 going yet, bro?

 

Well I am still waiting for the delivery of the Drives I paid 2nd day air and they shipped on Friday I dont know why but the drives have been on my local sorting facility since Saturday I called them saying come on its already here cant you just deliver it they said nope you paid 2nd day air you wait till the estimate delivery date. X9100 Just shipped today it should be here Wednesday or Thursday Also my Notebook cooler should be coming in Wednesday or Thursday.


I have a lot of stuff to keep myself busy Upgrading the M17 cant wait to install those drives in Raid 0 and the X9100

 

The drives won't do anything for gaming (you know that), but that X9100 is gonna kick some serious butt. I'm excited for you.

You should get some before and after temps with you notebook cooler when you get it.

 

Hmm, I only took the stock 160gig drive, as I don't keep a lot on my laptop anyway. However, I think I'd like to buy another 160 and RAID them possibly.

I'm sure somewhere in this 80 pages is the answer, but may I ask what drives you bought Mike? And what would be a newegg match to the stock 160 I bought?

 

I don't think you should worry much about the hard drives failing, because it warns you before that happens, and they would stay running for a long time after the warning.

 

You know that with the M17 and the esata connection you really do not need to install 2 drives internally. If you wanted you could purchase external drive arrays and raid them anyway you want. You could even have sepearate raided arrays as well just plug in which one you need per project.

I use raided 0 and 5 because of video and thats on mac desktops but now with the esata I am not confined to a big machine anymore.

 

Hard drives can fail at anytime without any warning. Doesnt matter how new or the brand

however... there are ways to recover the data. specially if your HD has been partitioned (you dont need 2 independent HD) and you follow a simple rule: one partition for the OS and another for your important data

following the thread... I go for RAID 0

EDIT: RAID 0 and an external HD

 

Drives are on are to be delivered today


11:02 AM

On FedEx vehicle for delivery

 

Alright Intalling Drives and OS righ now

 

Just for the record, old polish sentence to this kind of situations:

"Never argue with stupid person, sooner or later he/she`ll bring discussion to his/her level and win by experience."

Good thing to remember in the future
