Just Google RAID-5 and see that it's not a good solution or go ask /r/sysadmin. How easy is it to upgrade parts once I have it all installed, specifically in regards to the processor? The concept of a RAID is to combine multiple, less-expensive drives into a single, higher-capacity and/or faster volume. Many claim however that in real world usage, the advantage is insignificant and doesn't justify the data security risk. Check This Out
Apparently it is pretty popular nowadays. If you are still unsure, the deciding factor here is how much storage you need the pod to provide. Mohammad naseer khan says: May 22, 2013 at 6:52 am sir please explain me, which RAID is most important in all the RAID category? If you want something more efficient Raid 5 or 50.

of the RAID. RAID is NOT a backup strategy, so it has no sense at all. It's also known as "disk striping." With RAID 0, data is written across multiple disks. If you are looking for something that will give you a decent amount of space with good speed and redundancy you should go with Raid 10, it is a Stripe of
Reply max says: August 21, 2007 at 8:57 pm you can get 1+0 on two disk using two partitions. Any answer or further explanation will be appreciated. Although RAID 5 can be achieved in software, a hardware controller is recommended. What Is Raid 10 a higher perfomance option drives must be in identical pairs.raid 1 is mirroring.
In particular, an N disk RAID 0 array can do N times as many random seeks (and thus random reads) per second as a single disk. –David Schwartz Nov 3 '15 For home usage, RAID 0 is interesting if you are after speed or RAID 1 if you want security. I've had a Drobo, it was a nightmare, finally turning into a brick. RAID0 will give you higher transfer rates on read and write while giving you the capacity of the sum of the drives included on the array.
Even with 4-5 drives, I could max out a gigabit connection. What Is Parity In Raid The caveat, however, is since all the data is spread across multiple disks, if one disk fails, you will lose EVERYTHING. Each RAID level offers a unique combination of performance and redundancy. Software RAID 1 solutions do not always allow a hot swap of a failed drive.
Raid 5 Explained
You can put other data on that partition but it apparently more common to use a separate partition. http://superuser.com/questions/3233/what-raid-configuration-is-most-appropriate-for-a-home-user RAID IS NOT A BACKUP. Raid Configuration Calculator This software does not mirror the primary drives but backs up files and changed files. What Is Raid Technology On some controllers such as HP ones, all available options can be selected even if there aren't enough disks available.
I'd rather use 3 drives for this than RAID5, and a stripe is only good if you don't care about the data on it. If you need a lot of storage, go theRAID 60route. It is also suitable for small servers in which only two data drives will be used. Any input is appreciated. Raid Performance Comparison
The best best option is to use TWO SEPARATE DRIVES for backup and let Time Machine do the work and eliminate the complexity of the RAID. If your house burns down… well, you get the point. Br says: May 31, 2015 at 7:31 pm In addition, I don't understand using Raid 1 and "a hardware controller." Please explain. this contact form It is doing so by using parity data.

So your two years 2012 and 2011 would be off site, and most you could lose in fire, etc would be 6 months instead of 24 months!
That's a solution more tailored to enterprise networks, however. The downside is that there is no fault tolerance. But, I wanted offsite data (home office) and looked at dropbox as a solution.

For more information, please review ourRAID performance levels. The caveat this time around is that storage efficiency is only 50% of raw disk space, and there is no performance benefit like the RAID 0. It is ideal for file and application servers that have a limited number of data drives. Normal procedure is to use raid4 to resync and then revert back to raid0.
I do not have an off site backup for the general system. What are your thoughts on the ideal RAID? Reply Joe C. Of course if the building they are in blows up then its all gone so offsite is smart.
Sun StorageTek SAS RAID HBA Installation Guide A P P E N D I X F Selecting the Best RAID Level When you create arrays (or logical drives) for the Sun RAID 1 is a very simple technology. Are you using Time Machine for backups or making bootable backups with something like SuperDuper? A RAID 6 is also known as "double parity RAID." It uses a combination of striping data and parity across all of the disks in the array.
I do incremental backups to my Raid1 array all the time. I am scared of Raid 0 for failures. Fault tolerance lessens interruptions in productivity, and it also decreases the chance of data loss. A RAID 1E array can be built from three or more disk drives.
It all on lives one shared RAID drive. Reply Guest says: August 10, 2011 at 6:46 am RAID 1+0 is *NOT* the same as 0+1 Reply durga prasad says: June 14, 2011 at 4:47 pm it excllent way of Now, backup. As for the Super Duper question, I use Carbon Copy Cloner to back up my Macbook since I need to have a quick recovery ability if traveling.
Time Machine can be configured to work with multiple drives and alternate backups between them. But may it be some change to retrive some of the lost data, without leave to a professional costing up to $1000?
