Thank God for RAID5

Dammit, I was already in bed when I heard what sounded like the smoke alarm going off. Stumbling through the dark I realized it was coming from the home office. Getting closer I realize its the RAID adapter alarm going off. Logged in remotely and check the event logs and realized SMART errors since last night piling up. One of the 40GB Maxtors finally decided to call it quits. No big deal and no bad feeling toward Maxtor. In the last three years, each drive has probably been hit with an estimated 80TB of data transfer.

A quick check with IBM DFT and Maxtor PowerMax confirmed the drive is now a piece of modern art. The warrnty check showed I still had five months left on the warranty. Well its all packed away for a trip to Texas.

Let this be a lesson. If the data is important enough, make sure there is protection again physical failure. Also have a backup against software failures and attacks. For those using AID0 (doesn't deserve the letter 'R'), make sure you have a backup somewhere.

Back to bed.

EDIT: Actually, just realize those four drives were my first ever purchase from NewEgg. I remember when I was debating whether they were a new Pricewatch fly-by-night outfit.
 
Amen bother, can I get a witness. When you do raid, then do it right. None of this aid 0 crap.
 
RAID0 and RAID5 are geared for entirely different applications/markets. If someone is foolish enough to use RAID0 on a server, then so be it! 🙂

The same can be said for SCSI and IDE devices.

I'd say it really depends if you can afford to lose your data should a single drive fail, raid0+1 would work, but at that point you already will need at least 4 drives, you'd probably have been best off going with raid5 (wish i had the money/drives to setup a nice file server) 🙂
 
I never could really understand why people aren't singing the "back up your data" song until they hear Raid-0.

Raid-0 configurations won't make your drives wear out any faster.....

I don't care what configuration you run..... if you're not backing it up... you're gonna loose it some day.

Raid-0 has nothing to do with it.

No but it certainly makes it a lot worse then if you where running without it 🙂

Amen brotha, go tell it on the mountain.

I use raid 0 for my main box (gaming rig and whatnot) and was using raid 5 on the wife's Wife's (server, lesser gaming box). I would backup the to pc's to each other but something very bad happened with a ghost image in the great crash of 2002. I'll never get some of that stuff back. Backing up to DVD these days though. No substitute for backups...sh1t happens.

Yeah, raid 0 won't wear drives out faster but you're in some ways halfing the MTBF for the array as a whole.

yeah, that is the kicker.

I Ghost to a HD that is normally unplugged..... then the really important stuff (not too much... pictures, financial, etc..) goes on CDs.

My personal 'best' was when I had one of my experiments go soundly south and fubar'd the OS. I smuggly grabbed the ghost disk and..........






copied the fubar'd HD right onto the backup...... :Q
