@Immutable92-Parity is difficult to understand, but it is basically a checksum of the other sectors in each RAID stripe. When a disk fails, the remaining data can be compared against the parity to recalculate the missing data. The parity data is the same size as the other sectors since parity is calculated on the bit level. So if the values of 3 bits are 0, 0, 0 then the parity is 0. If the values are 1, 1, 0 the parity is also 0. If it were 1, 0, 0 or 1, 1, 1 the parity value would be 1.

The only thing stopping me from RAIDing is the way you tell me that it constantly fails....ARGH.

@cummings4409 personally I use 2x 750 gb 32 mb cache 7200 rpm WD Blue drives in raid 0, along with a 2TB external storage that I have windows auto back up every night.

Many of my friends have been running raid 0 set ups since we where kids, not one of us has ever lost any data, maybe i've been lucky but i've never even lost a hd before had one pc for almost 10 years and the hd in it is still good but its only 40gb...take care of your electronics and they will last. Use dvd/rw's, usb drives, or better yet a back up EXTERNAL hard drive to back up your data using windows built in software, this is even safer then a raid 1 or 10 b/c its external storage :)

@TijmenDal if you consider raid 10, you got to think about it first

having raid 10 means having at less 4 drives

meaning you have to buy 4 drives, and also quadruplicating the chances of failing

but if your data is important at the same time that your speed is also, that a great thing for you, but if your looking at a home way of doing it

get 1 240GB cash SSD for your HDD witch can be all the way up to 4TB

cash means that it will put all the resent things in the SSD

@ComissarGramsci raid is to stop lost of data, it you get raid 0 wich is stripping, you actually double the failing chances, witch means bad things if your data is sensible

but raid one is copying the data going to both drives, which means your data is safe(exactly like if i where to copy a picture)

@ComissarGramsci I am pretty sure he is referring to any hard drive fail not the railing of the RAID configuration.

@HelmetVanga you spelt potato wrong...

RAID=Redundant Array of Independant Disks or/versus

RAID=Redundant Array of Inexpensive Disks

The storage and technology community needs to put and end to this charade...which is it???? potato vs potatoe
