![]() ![]() It's usually recommended that you make a backup of a RAID 5 system before rebuilding. If any of the drives fail then rest will carry on working although you need to get the broken one replaced quickly before anything goes wrong with the other drives, and even then the stress of the system rebuilding the RAID onto the new drive can cause others to fail. With RAID 5 you will always lose the capacity of 1 drive, but as you increase the amount of drives on the RAID you will still only lose the space of 1 drive. ![]() RAID 5 works perfectly well with 3 drives or more. Just a short clarification on RAID 5 & 6 in general terms I've never tried to use a multidock for RAID, although the blurb does say they can be striped But I didn't have success on my one attempt at a RAID on it, and I don't think your needs require a RAID anyway. A Multidock is a pretty cool unit for dropping in SSDs and editing, and moving on. But with the interfaces being faster, and the speed of SSDs, I'm not so sure you are in need of one. If you were doing uncompressed video, you'd need one. I wouldn't think you'd even see that much benefit from it. Next up, I have to ask if you are sure you even need a RAID. Maybe someone else has a positive experience they can share about it. But I thought I did, and it looked like it just didn't work. I scratched my head for a minute, and moved on. The Disk Utility told me it RAIDed the four SSDs, but my capacity didn't increase at all. I tried doing a RAID 0 on one a couple of weeks ago. The multidock only takes SSDs and small format drives. 10 is two RAID 0 's mirrored to each other, so you only have the speed and capacity of two drives. Useful for speed and capacity, but if one fails, they all fail. RAID 0 is a bunch of disks striped together with no rududancy or safety net. With four, your best options are RAID 0 or RAID "10". You really need 6 or 7 to make them a good quality, robust solution. That said, neither work very well with 4 or fewer drives. RAID 6 has taken its slot, though it loses a little capacity in favor of a better parity scheme. But from what I understand, RAID-5 has become "old school" in the world of RAIDs, and is now considered nearly obsolete in design. I've dealt with a lot of raid configurations, but I wouldn't call myself an expert. ![]()
