My HD/2K hardware setup… are 4 disks enough?

[Ricardo Ellstein]

Hi everybody.

Just reporting back to the COW on the results of the array. I built it just as I proposed in my first post with 4 1TB seagate SATA300 disks. Here are the results as measured by the BlackMagic Decklink speed test:

Data Read Rate: 404.1 MB/s
Data Write rate: 370.6 MB/s

It’s working like a dream with SD video. We’re testing it on HD next week, but it says it can read up to 76 frames per second on 10 bit YUV 4:2:2 1080, so I guess we’re more than OK.

The test doesn’t include parameters for 2K but according to my numbers the array should be able to handle it to.

The Array ended up costing about $1150. For a 4TB array that might even handle 2K, I think it’s pretty good.

Thanks to everybody who jumped in. The advice was very valuable.
