RAID0 recovery? - Page 2

Mindweaver · Dec 16, 2012, 03:56 PM

Yea, I always liked to put my boot drive in raid 0 using mechanical drives. The one thing most users overlook is finding a drive that is RAID specific like WD RE drives or Seagate's Enterprise drives. I still have 3x WD RE2 250Gb drives in RAID 0 (180 read, 170 write) that have been working great with out failure for over 5 years. Since, I've bought a SSD I use it as a boot drive now, and only use the RAID 0 for Steam games.

I do something similar. I have a RAID-0 of SSDs for boot and applications and a RAID-5 for music, video, and files. I do nightly backups of my RAID-0 to my RAID-5 and along with that I have an external backup that I backup the RAID-5 to once a week.

Nice! I have a hardware RAID 5 with BBU using 4x WD Raptor 10,000 rpm drives for my SQL Server. The higher rpm drives are nice and quick, but the failure rate is higher than a lower rpm drive. I lose a couple Raptor drives a year. I have the RAID 0 drives in a software array. I maintain 9x arrays total (6x hardware arrays, 3x software arrays).

SSD raid 0 here, and a raid 0 with momentus XT's for steam, backed up every other night to an external that's rotated out of the house every month.

Data backup is important, you can loose it very, VERY easily.

Wrigleyvillain · Dec 17, 2012, 04:35 PM

Yeah I saw a great analogy once: RAID 0 is like flying down the highway on a crotch rocket wearing zero safety gear. Man it's fast and quite a rush but if any one little thing goes wrong...you're dead.

Just bought a server-pulled, never-used IBM M1015 for only $75 on eBay which is a rebranded LSI 9200i. Doesn't do RAID 5 with out an add-in chip but that is just fine for my present needs. There are more available around the same price form other seller(s).

And sure "RAID Edition" drives are better with error handling (TLER) and have anti-vibration protections and stuff but they really aren't any more physically reliable than other 7200 RPM mechanical.

We are both wrong, so get your facts straight as well. JBOD does not concatenate disks, SPAN and BIG do.

A: You don't know what you're talking about.

B: The only place that says this is an uncited wikipedia page so learn how to do real research before you start spitting out crap that isn't true.

C: Being a system admin I like to think that I know a little bit about managing servers and what RAID controllers can do and I hate to say it but the "SPAN and BIG" thing is crap because I don't have a single RAID controller that has the option of using "SPAN or BIG" but every one of them will do JBOD.

D: If you really did any research you would fine that these terms don't find there way past wikipedia. Also If you also checked the sources on that page, no a single mention of this is made. Some idiot just added this to wikipedia without having any sources because there are none...

Aka: Don't use Wikipedia then pretend you know everything then act like your hot shit.

You should fix that wiki page yourself.

I guess if you wanted to be technical about it.

Not sure if I follow what you are saying here? Are you saying a non RAID-Specific 7200rpm drive is as physically reliable as a RAID-specific 7200rpm drive? if so I agree, or are you saying a non RAID-Specific 7200rpm drive is as physically reliable as a RAID-Specific 10,000rpm drive? If so then I have to disagree, because a higher rpm drive has a higher chance of failure then a lower rpm drive due to the higher write speeds. You don't buy a 10k or 15k drive for reliability, you buy them for speed.

There was already a debate. I added to the page discussion and marked it as disputed before I delete it. I want knowledgeable people to have the chance to chime in before I actually remove it.

For speed and write endurance. SSDs are faster but you'll wear them out faster in write-heavy environments.

Yea, I plan to buy a few SSD's next year to RAID. I've not jumped in due to price, but with prices dropping that will change soon.

Plus, I want a few more SATAIII RAID Controller Cards on the market. I want the prices to drop on them as well.

Yes, generally-speaking and in and of themselves. Not comparing to higher RPM, that's apples to oranges. Why I stated "7200 RPM" specifically.

Fyi I'm not the one trying to come off as hot shit. Lose the attitude mister big shot sys admin

In his defense, there has been whole lot of misinformation flying around this thread. And when the subject is something like RAID, that can be disastrous.

jihadjoe · Dec 18, 2012, 05:30 PM

^ plus the fact that the failure OP is experiencing has nothing to do with RAID.
OP made a mistake and messed up the filesystem. Even with RAID 5, or RAID 1 his array is still fubar.

The main point was that when a RAID 0 dies, it's dead, there is no recovery. I think that made it through the noise which I apologize for being part of.
