Sshd ?
on Feb 1, 2019 at 10:41:48 pm

Hello,

i wanted to build a RAiD working station. 4x4to
But i cant' find SSHD 4To 7200rpm.
I read somewhere that SSHD for video post production doesn't change big things as video uses more than the 8Go cache of these SSHD. Is it true?

What is a normal working station according to you?

Thank you
Pierre

Good luck finding SSDs with any rpms at all, let alone 7200rpm!

Stick with hard drives for your array.

Considering you're talking video, and editing takes shot from every place, trims 'em up and places them in a sequence you determine, you lose the advantage of a hybrid drive -- the ability to retrieve frequently-used stuff as fast as an SSD.

Besides, an array is meant to do what you want to do -- get fast throughput. And when you build a RAID 5, if one of the drives can go south, you replace the bad drive, and the RAID software re-builds the bad drive's data on the new drive. If I had the dough, I'd get a RAID 5 and I wouldn't waste it on some array of hybrids.

thank you,

but how to work with SSDs when just the footage of my film is 1To 500Go ? SSDs don't easily above 1To. And this is just a short film, i plan to make a longer film so i guess I will get 10 times the amount of footage.

What would be a working station for feature for instance?

Thank you
Pierre

Well, at work they gave me a 4-terrabyte RAID 5. It consists of Five 1-TB drives. Four drives for storage, 1 for checksums & such. If ANY one of the drives fails, you can re-build the data from the remaining 4. I haven't had a single, solitary problem.

Since hard drives come in capacities greater than 1 TB, you can have a RAID in 8, 12 and 16 TB capacities if you wish. You just get bigger drives. RAID 5 -- it's the secure way to go.
