Internal SSD VS External HDD RAID (Price and Speed compare)

[Gary Huff]

[Mansur Oscar] “The problems of 30 frames aren’t real life (look) like on 60Hz TVs (only I’m not sure about OLED TVs), but on 120Hz TVs it make the video double the 60Hz refresh rate, which makes the 30 frames look like the 60 frames which is looks real life, but later I saw the 120Hz aren’t good idea, so I have to find a solutio”

Well, here’s a problem: how are you going to get these high-speed framerates on TV? Blu-ray only supports 720p60, and a lot of streaming services do not allow over 30fps. How are you planning to show your high frame rate content?

[Mansur Oscar]

Well I’m not sure about that, But I have to save my real life videos as 60p, and looks like that is why my Samsung LED Series 5 TV doesn’t show the 1080/60p file from directly from disk, even it’s from Samsung Camcorder recoder! Samsung doesn’t play on Samsung! Computers are the master!
I think we should skip the Bluray as Apple did, and store our content as a content on disc (bluray) rather than making for bluray player.

I don’t have much 60p, as you know… most of content available are either frames 24, 25 and 30.

About streaming service, how do you say 60 frames isn’t allowed? or you mean progressive 60p isn’t allowed but interlaced 60i is allowed?
because for example, Aljazeera HD is 60 frames (you can easily know by the people movement)

[Mansur Oscar] “Aljazeera HD is 60 frames (you can easily know by the people movement)”

I highly doubt that it’s 60p, more likely 30p. I have yet to encounter a streaming service (YouTube or Vimeo for instance) that allowed 60p content. They all accept 60p content, but when you watch the stream, it will have been converted to 30p.

I had a similar dilemma. I wanted to be able to edit at home on my 2011 MBP every now and then, so I was about to buy an OWC external bus powered two drives USB3/FW800 RAID. My MBP has no USB3 port, but I could use my Belkin adapter at home, and the FW800 when on a ship, on a train or on a shooting mission. It’s about 220 MB/s USB3 or 85 MB/s FW800. I already do very basic cuts from 1080i AVCHD footage on an external FW800 drive, so it would do. As a different and maybe better option, I had an idea I could replace my current second drive (1TB 5400rpm in place of the optical drive) with a 1 TB ssd. So I ran a BM speed test on my system Samsung 840 EVO 250 Gb ssd, and to my surprise I read a very good 480 MB/s read and write at first test, then down to something like 35 MB/s write and 80 MB/s read on further readings. I don’t know if it’s a problem with my drive or if it’s normal, but all my other external drives offered more consistent results.

The Pegasus P2 thunderbolt series of RAID drives are well priced, as are the ProMax, LaCie and GRAID brands. For around $2k you will get 8tb of storage that is capable of around 450MB/s in raid 0. Long term it’s worth buying the 6 or 8 bay versions and running at raid 5 or 6 for a good balance of speed and safety. An 8 bay version in raid 0 would be achieving nearly 1000MB/s.

Unfortunately with the new Mac Pro, there isn’t the option to expand internally, and editing any projects from your system drive for an extended period of time isn’t the best idea. Thunderbolt storage is the way to go.

As you say For $2230, we have a 6-bay Pegasus2 with 12TB of storage that runs 800-900MB/s in RAID 5 configuration. That’s cheap. Anyone who doesn’t think so may want to find another hobby…

[Mansur Oscar] “You have catch me! I really liked you answers! “

Thanks. I hope it’s helpful.

[Mansur Oscar] “only I didn’t understand really this from you: (500 Mb/s storage will not cut it beyond a single stream of 1080p60)?
for the 30 frames are half the numbers Mb/s you said for the 60 frames, right?”

Yes, they are.

See the Appendix of the Apple ProRes White Paper [link] for more on target data rates.

[Mansur Oscar] “by the way, where and what is ProRes Challenge?, I searched for this but I liked from you to give me your recommended way.”

I just made it up. I meant for you to take some of your uncompressed video, compress it with ProRes 422, and compare them side-by-side to try to tell the difference.

[Mansur Oscar] “I have to find a solution, and you have answered my solution; it’s the serious storage! I guess it’s the SSD RAID Thunderbolt 2”

I personally use a mix of HDD RAID and solid-state storage. Each of my workstations has a locally-attached SAS RAID (Thunderbolt 2 would be fine) for a blend of speed and capacity as well as either internal SSDs or solid-state PCIe cards for fast but small storage.

Walter,

If you’re taking this on the road like Pepsi – remember you’ve GOT to email me when you come to Arizona.

You can stay in the guest house and I’ll even provide meals.

a special Thanks to Walter Soyka, &Thanks to you all everybody!

I got my way to what to do, I should choose too small (under one 1TB SSD) or too big huge above 4TB RAID, choosing normal stage is overpriced.

Gary Huff, isn’t 30p and 25p lag movement? (non real life?), I have my old sony camcorder 8mm, they’re 50i and it’s real life like.

The Aljazeera HD should be 50i or 50p, (sorry to say 60i, maybe in USA 60i)

Lag movement? Never heard that before. It has more to do with motion blur. The less, the more life-like it looks.

60i and 60p are different. 60i looks like crap on anything but a television screen, especially streaming onto a computer monitor. 60i is really 29.97.
