Using Seagate Momentus XT Hybrid for R3D editing ?

[Jack Colquitt]

Hi,

I'd like to use in my laptop in non-raid configuration, 2 Momentus XT 750Gb,
one for footage and the other for temporary and render files,
and a Msata 128Gb for OS and CS6.

I already know my laptop is strong enough to read R3D in full 4K with CS6 and SSD + 32G RAM + GTX680M + i7-3840QM.
But is it possible to do the same with this hybrid hard drive instead of SSD ?
In this benchmark you can see that those hard drive can read at 100MB/s,
and if I'm right, the R3D has debit rates of 55MB/s... so in "normal" editing situation
(I mean a editing with no more than 2 different footage by sec),
do you think it's possible to edit in full 4K resolution with those drive ?
(or at least half-resolution !!!)

Thanks.

Are you sure your laptop can read/run 4k at full res? The thing about R3Ds is that it isn't datarate of the SSDs/HDDs that's the issue (as you said, 55mb/s sustained isn't too hard to find); the issue is the debayering of the r3d raw files, which is entirely dependent on the CPU... The only alternative to CPU power is a REDrocket.

In other words, if you can run 4k at full-res with the 3840QM (are you sure?), you should be able to run it off even a 7200rpm HDD.

I understand your skepticism, and I thought the same before seeing this video showing a Clevo i7-3920XM + GTX670M + 32GB RAM + SSD 512... crazy !!
(unless you try to overclock it, the i7-3920XM is 2,9gHz with 55W comsuption, but the i7-3840QM is 2,8gHz, 45W, and 500$ cheaper for only 0,1gHz less !)

So I will buy the same laptop, but I have the choice between 2 expensive SSD 512Gb, or 2 bigger and 800$ cheaper hybrid HDD 750Gb + 8Gb SSD...
but, of course, I don't want to take hybrid HDD if it's impossible to edit R3D with it.

The hybrids are made to be used as boot drives, not storage. They use the additional SSD on them as a sort of RAM Disk to keep frequently accessed files like system files on, mainly really small files that get written to and accessed most. It won't do anything for R3D workflow other than possible crap out sooner. Better off with a plain 7200rpm drive. Can't you put a Velociraptor in some laptops? That's the one you want if you're not going RAID or SSD.

WD Velociraptor (or 10K Seagate Savvio) are 15mm high, but the Clevo laptop I want can only take 9,5mm drives.
So in this case I can only take regular 2,5" 7200 HDD (or SSD)... but what I don't understand is why people said
a regular 7200 HDD can't read R3D, while I can read 4K footage on a Mac Mini Core2Duo 2,26gHz with 2Gb RAM ??!
Of course Premiere can only work at small resolution, but my dumb 160Gb 7200 HDD seems good with debit rates...
so, to be sure, am I wrong, or a regular 7200 HDD can read R3D ?
(I don't speak about processor or graphic card, but just HDD debit rates)
