Solve : Raid setup help? |
|
Answer» I am looking to set 4 sata drives up in a RAID setup for backup purposes, I am however unsure what raid type to use.I'm not a RAID expert by any means but RAID 0 is not what you should use since you mentioned "backup purposes". RAID 0 uses "striping" only (no parity or mirroring), which is not what you want. You need one of the other types of RAID but, since I'm no RAID expert, I don't want to recommend a specific type. I am looking to set 4 sata drives up in a RAID setup for backup purposes, I am however unsure what raid type to use...RAID 1 - Mirror Don't know why you need 4 drives for RAID backup.Check out this article. It may help you make your mind. http://en.wikipedia.org/wiki/RAIDComputer_Commando: When first starting this I thought there was a RAID where you had data over all the drives and if one dies then you just stick in a new one it rebuilds and your data is still safe. Am I wrong? Hmm does this sound like RAID 5?I guess one of the first questions should have been what are you trying to do and what is your budget? For a home system, raid 5 is over kill, but for a commercial system it may be what you need.I am just going to get the drives as I get the money, I want a raid system that if one drive dies then my important FAMILY documents and movies are still safe, and want heaps of space to stick all my stuff Quote from: nedkelly on August 26, 2010, 02:43:10 PM I am just going to get the drives as I get the money, I want a raid system that if one drive dies then my important family documents and movies are still safe, and want heaps of space to stick all my stuff A RAID array, in any configuration, is a poor substitute for proper backups.yeah but I have a LOT of stuffThen you should have a lot of backups... I have alot of stuff too...patio = mod? Well I already have the board the ram and the psu, just have to modify the case a bit.

Am I wrong?Not wrong, but maybe MISGUIDED. I experimented with RAID 1 for a while. RAID 1 with, for example, Drive A & Drive B. Drive B is a mirror (exact duplicate) of Drive A, If you lose A, B is always there to take over; you then replace A as soon as you can. Whatever is written to A is written to B, so writes are a bit slower, reads a bit faster, because it COULD read from A or B. The RAID controller does everything, not Windows. RAID is useful if you're running a server, or a computer that can never, ever be down. Better to follow BC_P's & Patios's advice. |
