What make RAID 0 delete all files just because of a lose wire???

I have had people tell me before that you will lose all your data in RAID 0 if a SATA cable came undone...whyis this? What on Earth could make it lose all your data just because of a lose wire???
 
I think they mean if you disconnect the SATA cable when the computer is on, theres no reason you cant do that when you shut down the computer.
 
well you can buy the clip on sata cable, these came with my evga mobo their black and has a silver clipping to hold the hdd. :)

yeah the old red ribbon cable, some of them are loose. i got a couple red ones that are really tight.
 
I Know I have 4 of those metal clip ones, thing is I dont care about doing it, I just want to know why it does this. To me, I see no real resons for the data loss to happen, I want to know why, not how to prevent it.

hmm... so,. you are Actually asking that if the Data connection cable, between the motherboard and the HDD is disconnected why you lose the data? I'm sorry.. But that just really seems like a no-brainer to me.. =o
 
How is that a no brainer? If you disconnect a running drive that isn't in RAID you don't lose all of the data...
 
Well then would you mind sharing it to me? To me, I would think all the data would be on the HDD. What makes it corrupt or what ever. Why cant you just plug it back in and all is well?
 
A Raid0 works because both drives are in perfect synchronisation with each other. When one cable gets unplugged with the pc on, instantly both drives don't have a matching pair of data halves. The data doesn't just disappear, but it's like having two jigsaws with all the pieces in one box, and no way to know what pieces are from which jigsaw, if that makes sense.

By the way, it's happened to me, a dislodged cable, and I lost nearly 400GB of data, so it does happen.

I've never had a problem where the cable comes disconnected from the drive when the computer is on, if it does, then you did a bad job installing it, or your trying to move your computer when its turned on.
 
yes... because half the data is on 1 disk, and the other half on the other.. but then, the risk isnt bigger as a single drive failing.
 
If you had 2 drives that weren't in raid and one failed you would still have half of your data. There is a little more risk.
 
Magic man already stated why this happens, but I can maybe shed some light on the subject. When you stripe two drives into a RAID 0 array, they are in returned combined into one drive. Both reading and writing data randomly to each disk, so effectively each disk contains half the data.

If you want a reliable RAID and you would actually benefit from the performance increase, and I am going to take a stab int he dark here and say probably maybe 5% of this forums users would actually benefit from running a RAID, you should look into a RAID 0 + 1 which allows both striping and mirroring for redundancy.

Or build a RAID 5 if time is really money for you. Otherwise I recomend you just use 1 single HD and any additional HDs you use for storage for whatever (apps/data/etc).

heh... yes.. but Raid0 makes 2 (identical) HDD's show as 1.. so comparing 2 disks in raid0 and 2 spereate disks isnt entirely fair.. while comparing a raid0 setup and a single disk is. (risk wise i mean ofcourse)

The data's still there, just not usable, as the 2 harddrives aren't synchronized. It's like 2 people running with their legs tied together. If one trips, they both go down.

That has got to be the best and most down to Earth explanation I have herd all day. Thank didyouknowthat, I get it now. Odd, such a great thing has such an easy fallback. tisk tisk tisk.
