Linux Hardware: Harddrives for Video Editing on Linux

Making of Tron II
I like to shoot and edit video (on Debian GNU/Linux, of course on KDE, using the wonderful KDEnlive Video Editor), but in video editing, there is always a bottleneck.  My wife and I recently purchased a Nikon D5100 camera which shoots fantastic video in hi-def!  I was worried that my video editing computer hardware wouldn't be able to keep up with these large HD video files.*


With my last hardware refresh, I purchased a new Western Digital Caviar Green harddrive; the Green drives spin at a lower rate (5400 RPM) which I worried would impact my video editing performance: this drive was planned for long-term data storage only, not for live video editing.

What a cache!

I was pleasantly surprised to lean that this drive can keep up with my video editing needs just fine.  Maybe its because the Caviar drives have such a large cache at 64MB?  Is it the SATA2 and SATA3 speeds?  And at the current prices for moving drive storage, its hard not to like what these drives offer: good performance, fantastic 64MB cache, low-power use, huge size, SATA3 interfaces, and at a great price.  Two terabytes for under one hundred dollars!  Amazing times.

Check out our other recent Linux Hardware reviews for a USB Wireless-N Dongle and for a SuperSpeed USB3 PCIe card.


* For anyone interested in what video format the Nikon D5100 shoots, here is output from the 'ffmpeg -i FILE.MOV' command:
ffmpeg -i FILE.MOV
Stream #0.0(eng): Video: h264, yuvj420p, 1280x720 [PAR 1:1 DAR 16:9], 5696 kb/s, 23.98 fps, 23.98 tbr, 24k tbn, 47.95 tbc
This is shooting at 1280x720 (720P) 24fps.  The drive can also handle 1920x1080 at 24fps and 30fps, but I don't need that high of image quality and I prefer the film-like 24fps.

Thought you were going to write about an SSD drive.:)

@Anonymous That's a good point, and from what I've seen the SSDs are incredibly fast. But if these lower-cost, generally low-power, spinning drives work reliably and have such huge storage space, I think they're the way to go for video editing at his time. If an SSD was liimited in storage space, you could always use the SSD for the 'active media' and move stuff onto it as you need, but these Caviar drives have been working quite well.
