What are the different raid setups

I am running Windows 7. Any info would be a great help. This would be a lot more simple with a Linux system, because it has much better facilities for accessing drives other than as filesystems. Ask around your circle for someone who has Linux knowledge. Whatever you do, do not put the drives into a hardware RAID device and install them as a striped pair. The RAID controller is likely to overwrite some of the data on the disks, as soon as you do this.

I was amused when this popped up on Google. You do have a point that for completeness both versions should be included, so I updated the page. Thanks for the feedback! This was useful since at the time hard drives were VERY expensive, especially as size increased. It was cheaper to create a large RAID array inexpensive of disks than it was to purchase a single drive with the same capacity. I would like to find some documents on what each RAID configuration would need as a minimum from the server it is running on.

It worked for documents, but not for large or small amounts of data needed to be drawn. Its hardware was very subpar, and although it makes a big deal of being a quad-core, its limit was mhz, which is not as fast as current high level cell phones. The tech who set it up could not see how a RAID 5 could slow it down, I just wanted to eliminate redundancy altogether except for my manual but effective backups at night and lunch.

In my effort to procure money from my manager I rebuilt our old server with new cooling and clean install, as well as RAM improvement to 3. The D-link would render my mock up map in seconds, the old server took 7 seconds. This D-Link should only be used for homes or documents. Large datasets are useless, write speeds are terrible, as are read. It was a nightmare.

And the fact that the old 32 bit with an unreal amount of use was made to look like a giant rack system comparatively was not enough to get any money for a new server. A City Planner has not enough skill to set up a monitor, jerk move on my part, but deserved. Amazed to find City Planners have no mathematical skills, coming from Engineering I assumed they were similar. Point is, Planners are useless managers and have no skills. And I could go on! Raid systems are to protect data and that is given!

How one likes to protect data is decided on the conditions and requirements. To make it short; to be secure at home, get a cloud storage which is slow but very safe as the large service providers take this very seriously but it is a bit expensive or buy a back up drive from Western Digital, Seagate etc.

In my case, I want my data access to be fast, failsafe and accessible from anywhere in the world! What do I do?! I get a raid system like Raid 5 or 6 with 6 drive bays, a back up system to automatically back it up and get a service provider to have them connected to internet like it is in the cloud but actually it is a private cloud.

One can also have a cloud storage lage enoufh to replicate the data at home which is stripped with parity and backed up. It sounds like overkill? What is parity?

It is the end result of calculation of data written on a disk as in 1s and zeros. The result is also in 1s and zeros. You write the result in the parity section which is also distributed so that it also has parity information. It took us haf a day in class some 20 years ago to understand and learn but you do not have to go through that. Imagine there are 5 disks. Data you lost on a drive is missing but like a puzzle, you have all the surrounding lines that are continuing at the other side of the missing piece.

You also have the colours. More, less, this is the idea. This is a nice write up, but missing some basic logic. Other than that, it has the best performance and redundancy of all RAID levels. I currently have 11TB of [ictues on a 12 TB drive. Is there another Raid configuration that is better for capacity and redundancy, plus speed?

I have an array of 12x12TB drives. I created a RAID 6 across all 12 and then created one partition and am using an xfs file system. I am getting about 1. Thank you. RAID 1: Not sure. If yes that what is procedure. If RAID 5 is configured it will take time for rebuild data.

Simply like RAID Raid50 is a strip of groups of RAID5. They say better write performance and increase data protection.. So if you have 9 HDs, create 3 cells of RAID5, meaning you can have 3 simultaneous fail providing no more 1 fail in each group. My data can be split two parts: raw data like compressed video and document files and in-process data like the data extracted from the compressed ones and need to be processed further. Hi, I am setting up a large array for a surveillance system.

I have spoken to some people about the size of hard drives available. Given that the MTBF is the same for the drives, the lower number of drives has a lower potential for a failure. The more drives you have, the more likely a failure. This ends up without a parody Drive involved which means a failure of one of any of the discs would result in the loss of all data in the raid array. RAID 1 offers complete redundancy. With 2 drives, it will mirror all data to the other drive, with 3 drives, it will mirror to both the other drives.

It will continue like that for as many drives as you put in. Your space will be limited to your smallest drive in the RAID 1, no matter how many drives you have. Chances of losing data in a RAID 1 get increasingly lower the more drives you have, but it also makes it very expensive per GB.

Hope that helps. I would like to know if it is possible somehow to install Windows 10 on Raid 0? If so, how would I proceed? When prompted, you would then insert the disk with the driver on it. Most RAID manufacturers have an option to create the driver disk. However, if you have a HDD Raid controller card, or a raid controller built into your bios, then you can create the raid there. Then using the Drivers for the controller, you can install Windows.. Anyway, I think the dual drives in the enclosure are fine but power suddenly just cut off.

My question is this: Can I take out the platters and put them in a dual dock 3. Or is there a way to repair the power issue in the enclosure? It fired right up perfectly. Daniel Smith 4 drives of 3 Tb in raid 10 is 6 TB because the you combine 2 drives as raid 0 and the other 2 are used a mirror Those who work with large amounts of data should choose between raid 10 or 6 In my view today raid 5 is no longer a good solution because of bitrot..

However the most secure is in my view raid 6 till the grow beyond the max of raid 6 is reached and it looses its ability to proper restore the files. Raid10 Am I right to be scared of mirroring? Is Raid10 failure along similar lines possible?

Even a software raid should be telling you which drive is malfunctioning — at least Linux will flood error log with messages of failed drive. If you have 4 separate raid 5 arrays, would a hard drive failure in one of the arrays affect only the performance of the one array and the others would remain unaffected?

Can anyone explain this? You have a file that is broken into 10 chunks, and those chunks must load into memory before you can use them.

So on one dish, your hard drive controller loads block 1, then block 2, then block 3… etc. In raid 0, it would load block 1 and 2 at the same time, then block 3 and 4.

But if you lose a disk, you only have half your file. What you are recommending will not increase speeds by much, unless you are loading to files in separate folders. Thanks for beautifully explaining the types of RAID. I am a tech guy and was using RAID 5. Somehow, I had lost the data from it. So, I asked the solution from my colleague and he advised me to use Stellar Phoenix raid recovery software. This works great for me.

Stellar Phoenix is a scam company and this fake comment is just sock puppet marketing. Buyer Beware. Great post! When backing up data I always use the style strategy. But, more is always better. You opt for Dual mirror: so in that case, no need another drive for TM? If TM, then the drive is also need 3TB? You can put other data on that partition but it apparently more common to use a separate partition.

The mirrored drives protect your data against 1 disk failing. Accidental errors like incorrectly deleting a file or misplacing it or data corruption are more common and a bigger worry. That is why you use Time Machine for the data residing on the internal drive but of course the same also applies to the data that will be stored on those mirrored drives.

So in my opinion, the ideal setup is that the third drive on which you put your Time Machine data is also a 3GB drive, split into one partition for Time Machine and a second bigger partition on which you occasionally copy the main data stored on your mirrored drives. I know that adds to the cost but I like having a spare copy of data and I like having systems with disks that are all the same size. Easier to resell afterwards, easier to repurpose as a 3-disk RAID set if your storage needs change over time.

Also if I would like to use this ext for Time machine, do I need to partition as well? As have3 HD 3TB for data? I would personally opt for dual mirrored 3TB drives instead of 4x 1 TB. It is simpler, offers better performance, makes less noise and uses less power.

When you add a third disk for Time Machine you can still do it all with a 4-disk enclosure, instead of having to buy a more expensive 5-drive system. With 3 disks in use, you still hafe a spare slot if you want to expand storage in the future. If you go for a NAS box its software takes care of making those mirrored drives appear as one partition. Check out YouTube videos on setting up a Synology, Qnap,… system — it is pretty straightforward. One question. If we take RAID 5, what is pairity checksum features.

If we have 4 disk and configured raid It will do stripping means fast data flow as data being distributed but what is pairity for? The parity is used for recovering data in case of drive failure. With RAID6 two disks can die simultaneously. More detailed descriptions of the way parity works can be found elsewhere on the web. This page is meant to give a general overview.

It allows for the failure of two disks simultaneously with no data loss. Slightly slower than RAID 5 on writes but there is no added delay for reads. RAID 10 is secure because mirroring duplicates all your data.

It requires at least 6 drives. One drive from each of the RAID 5 sets could fail without loss of data. The time spent in recovery detecting and responding to a drive failure, and the rebuild process to the newly inserted drive represents a period of vulnerability to the RAID set. It requires at least eight drives. A great fit when you need higher usable capacity and better reliability. Slight loss in write speed and performance. Want to learn more? Combines two or more hard drives together and treats them as one large volume.

Mirroring creates an exact duplicate of a disk. An obsolete implementation of striping similar to RAID 0 — it stripes at the bit level instead of by blocks. It adds fault tolerance and grants two disk drive failures for the RAID 6 array. Additionally, each disk has two parity blocks that are stored on different disks in the array. RAID 10 usually is applied to places that require extra high disk performance and redundancy. How do you manage RAID? To do that, you need to use a professional partition manager.
