Looking for advice on setting up video raid
I’m thinking about putting together a video raid and would love to get some advice from others who may have done so. Looking to spend @$3K for speeds in the 750-900MB/s range. Here’s the setup I’m considering:
Areca 4036ML or iStorage Pro iT8SAE6G chassis
Areca 1882X or Atto r680 controller card
8xHitachi Ultrastar drives (size TBD)I’ll probably set it up as a 7 drive RAID 5 with one hot spare. Ultimately, I will also have it backed up to a NAS drive array for added security.
Any advice from others who have put together a similar setup or suggestions for something better would be greatly appreciated.

sounds good to me. SAS provides you with good speed, 7 plus one spare is fine, the Ultrastars would be my recommondation as well. We run a Sonnet SAS for years, it’s very good, but Areca should be a good choice too. Welcome to the world of fast and reliable arrays.
Just consider Alex’s advice with expandibility of the raid. Might be worth looking into.Cheers

you could also have a look at Axus SAS raids, they are expandable as well. We run a big AXUS Yotta 3 FC raid with good results. The Hardware is pretty solid.

Good point on the expandability, Alex. I was considering going with 3TB drives to have a full 18TB of useable storage. I’m thinking that’s enough but these days you never know. The iStorage Pro unit that I mentioned above is expandable for about twice the price of the Areca. Definitely something to take into account.
Rainer, I’ve also used a Sonnet array (Fusion 800 I think) which has been pretty good aside from the bundled r380 card failing once and having a loose drive cable another time. But overall, speed and reliability were pretty good. Definitely hoping to hit a lower price point though.

Why not just do a RAID-6? Less chance of URE problems on rebuild than RAID-5. Read/Write speeds shouldn’t be that much different, especially with Areca. Overall better use of same number of drives.
My 2 cents.
Good Luck!

Yeah, that’s a good point Todd. In theory, the speed should pretty much be the same, shouldn’t it?
-
yeap, speed is almost the same with a 6 bay raid. Is there a huge price difference to an eight bay?
cheers

Read speeds should be similar. Write speeds may be slightly lower on RAID-6 because of the dual parity, but I have had excellent RAID-6 write performance with Areca. Last Areca card I had did very similar specs at RAID-5 and RAID-6. Other cards, such as Highpoint and Promise, not so much – can’t speak personally for ATTO, but I hear good things.
