raid0 failure within a month- WD 6tb
hi friends, following certain advice from this forum, A month ago, I set up raid0 using two WD 6TB red hard drives for data storage (film editing), connected through my asus z87pro motherboard. I did this by adding some raid files during reinstallation of my windows 7 OS. Raid successfully created, it shows 10TB as a single folder and the Intel Rapid Storage Technology application was running fine. I never used the Raid drives for any purpose since it was created as I was extracting video footage in other drive.
A couple of days ago, I got an error notification telling me that raid drives failed. Intel Rapid Storage Technology showed that there is a disk failure and data may be lost. The connected two hard disks were marked with red cross, alike (as if both failed). When i restarted the computer, it showed me in red color that “error occurred in connecting” in member raid disk drives. Non-member drives were fine. At the time of failure and since the time i created, I at least have three 4TB external drives and three 2TB internal drives all connected to my CPU (cooler master haf942, asus z87pro mother board).
I now deleted the RAID set up and created new raid0 volume (luckily i had no data) and intel rapid storage technology shows “running normally.”
Just in a couple of months, how could a raid0 fail?
Does overloading the cpu with many connected hard drives cause the raid failure?
due to interruption in power supply?
Can i turn the raid drives “offline” in disk management tool to preserve it until usage?I am aware of the failure rate, but poor management would cause early failure, so pls suggest me to maintain the raid0 drives. Thanks.

how could Raid0 fail? – because ALL DISK DRIVES SUCK. To be clear, all disk drives, even enterprise disk drives, are of poor quality.
NO ONE should EVER do RAID 0 for any reason (other than to boast performance speeds in a magazine ad). You are begging for trouble when you use RAID 0 – and I guess that you found trouble. What is the solution for you – BACK UP YOUR DATA constantly, and NEVER EVER use RAID 0 every again.Bob Zelin

thanks bob.. I opted for raid0, mainly for space and speed. My source footage is 3TB. For roundtrip, i create a proxy which would be around 1TB and take a colored master of about 2TB back to premiere for final DCP output (theater).
So, i am sure i need a total of 6TB. So if i want to connect raid using asus z87pro motherboard, i was suggested raid0 or raid1. Now after ur suggestion, if i chose raid1 over raid0, i can manage with the speed but doubt for space as I have two 6tb WD red hard drives. Or will raid-1 be fine for the space requirement? thanks

Bob,
Sounds like this guy is only using 2 drives, so his choices are RAID 0 or RAID 1, both poor options, but the only ones he has.
Anand, RAID 1 you will lose 1 drives capacity & 1/2 the speed of RAID 0. Bob’s right though, RAID 0 affords you no protection in the event of a drive failure. If all you’ve got is a 2 drive RAID, RAID 1 is your only real option, but the trade off is slower performance (1/2 the speed of RAID 1) & only 1 drives capacity.
I would highly recommend an external RAID with at least 8 drives in a RAID 6 configuration (for the best in protection & speed), but then again, that all depends on how important your data is to you. I always recommend having more capacity/overhead than what is needed in any particular project to my customers.

Thanks Jon,
my project is an indie film intended to get buyers for release. There is no deadline. All i have to worry is for quality.
Raid with at least 8 drives is good but I cannot afford currently 🙁
My footage is 5d3 magic lantern raw files (1920X1080) which require 150 mb/s transfer rate. I recently found that one of my external WD hard disks provided me a real time playback during a trial roundtrip. So my raid set up with two 6tb WD, I hope, would give me enough speed even if I use raid1 (totaling only half the capacity of two drives and the speed of a single drive). But like you told, I will be working for a long time with raid, so raid1 would be better compared to raid0. Even if i am short of space, I can write my rendering data to an external drive. All i need for video editing is the read speed.
Just wanted to know if the above sounds good (with raid1) for my indie project. thanks again

You should be fine in RAID 1 as long as you have the space & the speed to get the job done. RAID 1 over None for sure!

thanks Jon 🙂
A doubt is that .. is raid0 failure a failure of the setup or the disks as such? because am gonna use the same two drives for creating raid1 volume. Currently it is in raid0 (reconnected after the first failure) and normal. I am gonna change to raid1. So i presume it is the set up of raid0 that is failing rather than the disks and so i can go ahead creating raid1 with those two same WD 6tb drives right?

Anand,
I hope I understand correctly.
If one of the 2 drives you had is bad, you need to replace the bad drive before creating a RAID 1 set.

Hi Jon,
Raid0 was a failure because the intel rapid storage technology application showed me red cross mark on both raid disks (6tb WD). There was also “error occurred in member raid disk” during computer restart.
Now I deleted the raid0 volume and created the raid0 volume again (before my first post). Now the application shows the raid drives are Normal and a folder with 10TB created in my computer.
My doubt was that now it shows normal, so the disks might work good and there was a problem in raid0 setup. Because the disk are presumably good, shall i go forward with raid1 volume creation?

Anand,
Sounds like you’re all ready to RAID 1

If you care at all about the data, stop using RAID 0. It doesn’t help in editing speed and just multiplies chances of failure, especially on big drives.
WD Red drives are optimized for NAS and RAID in ventilated enclosures, but RAID0 in a PC is not really the proper use.I am running now a RAID5 with three drives on Intel ICH10R and never had an issue. But those are not cheap “desktop” level drives.
However, I did start to see problems with both my WD and Seagate drives (not RAID, backup externals) just because… they lowered the price/GB. I think that in order to compete pricewise, they increased the density to unsustainable levels, especially on bigger hard drives, resulting in lower MTBF and shorter warranties. Heck, for some of <4TB drives they needed to lower the RPM from 7200 to 5400 just to be able to keep the errors low – for the brand new drives!!!
MTBF has also hidden connection to Non-recoverable read errors per bits read – WD RED has listed 1 per 10^14 bits.
If you have two drives, one 2TB and one 6TB, with same MTFB numbers, the 6TB one is three times more likely to fail in the same span of time. When you added two of those in RAID 0, you just doubled again the chance of failure.
