What are Levels of RAID 0 1 5 and Which one is better and why?

RAID 0 is the best for speed because it uses "data stripping". That means if one drive fails, all you have left on the other one is useless bits and pieces of your files. That means one drive failing will corrupt ALL your data. If you choose RAID 0, you MUST back up your data at the very least every day. Preferably every hour. Automatic back ups is a good idea anyway. RAID 1 uses "mirroring". When you save a file, it gets saved to BOTH drives. Putting drives in RAID 1 does not make the system faster. That means if one drive fails, the other one will still contain all your data. The problem with RAID 1 is that you only get HALF of the space you bought. For example, if you put 2 drives with a 3TB capacity in RAID 0, you would have 6TB. 2 drives with 3TB each in RAID 1 would mean instead of 6TB, you would only have 3TB. The reason for that is because both drives contain the EXACT same data. RAID 5 is pretty good for speed and if 1 drive fails, you can just replace it and rebuild the RAID 5 array without losing any data. RAID 5: RAID 1: RAID 0: I would create a RAID 0 array to store your files and if you care about any of the files you would store on your computer, a RAID 1 or RAID 5 array (I would recommend RAID 5) to back up your data to. I hope this helps.


Which RAID level stripes data across multiple drives to improve performance?

Every RAID level stripes data across multiple drives, which improves performance compared to using a single disk. RAID 0, RAID 1, RAID 1+0, RAID 5, RAID 6, etc. all have better performance than a single disk. Other than RAID 0, all other RAID levels provide fault tolerance. RAID 1, RAID 1+0, RAID 5, RAID 6, etc. all have fault tolerance.

What additional hardware would be necessary to implement each of RAID 1 and RAID 5?

Essentially that just means understanding what raid one and raid 5 are. Raid one stores the data on 2 hard disks, raid 5 stores the data on 3 to 5 disks. In either of these circumstances all the hard disks must be completely identical right down to brand cache, size etc.

What raid uses least number of hard disk?

There are three types of RAID RAID 0 (Stripping without parity) The records are distributed among all the available HDDs. The number of the HDDs may vary from one system to the other RAID 1 (Mirroring) This uses double number of HDDs. One stores the records while an equal number of HDDs forms the backup. RAID 5 (Stripping with parity) This type of raid distributes the records in n-1 disks while maintaining 1 disk as the parity disk. assuming 4 HDDs are required RAID 0 uses all the four RAID 1 uses double RAID 5 uses 4 + 1
