RAID and Storage
Hey guys,
A pretty simple question for most of you… Right now I only have 4 WD Caviar Black x1TB (total 4TB) currently set on a RAID 5 (Apple RAID Card). Not a lot of storage due to a tight budget…
Anyway, I am only getting an average read/write speed of 260-270 Mb/s. I would like to set my RAID to “0” but I’m concerned about hard drive failure. However, I know a lot of you out there set your internal hard drives at RAID 0.
– How often do WD Caviar Black Hard Drives fail? anyone had any experiences?
– What’s your backup plan in case of a hard drive failure? Would having an external hard drive for time machine be appropriate??
– What would you guys recommend I do to increase storage performance without spending lots of money?
I’ve looked around the forum for answers but didn’t find what I was looking for.
Regards
Alex.

The Accusys drives are pretty good. I think there is a model recommended in the Resolve configuration guide.

Al drives fail.
I am only getting an average read/write speed of 260-270 Mb/s.
Why isn’t this enough?
Your system drive as a part of a RAID0? wouldn’t recommend it.

Thanks for the reply.
I will be working with RED footage without RED Rocket. I figured a higher storage speed might be useful. What sort of footage do you usually deal with?

Thanks Rohit,
Do you recommend I change my current setup to RAID 0? I’m just trying to find a way to spend the least amount of money possible..

260 is plenty for r3d. The issue you’ll run into isn’t drives but debayering. Which is done on the CPU. Faster drives won’t help.

Mb/s is suggesting you’re going 30 MB ( megabytes per second )
I’m sure you mean 230 MB/s, which is fast enough for for UNCOMPRESSED HD.
But datarate isn’t your problem with R3D playback.
You can’t get full quality playback without a Red Rocket.

In any, ANY circumstances, ALWAYS, even when using mirrored raid, keep the copy of ALL the footage on cheap Hard disks in the safe place. Or be sure that client do this. Then even if your raid would crash (i do not know a person in our business who didn’t have a raid crash once) you’ll be safe. I often use raid 0 setup, but I do not think about possible crash as I have a copy of important footage at hand. The shooting day is much more expensive than couple of hdds.

Fire, water, coffee, power, theft.
No RAID system is safe.

Thank you for the advice Mikhail,
So its obviously a good idea to keep backup of the Raw footage its self, but i’m guessing you also keep a back up of the interface work?

Thanks Juan,
Would there by any way to avoid or reduce this? (sorry, I’m still new to the resolve system).
