« on: December 29, 2018, 09:09:36 PM »I have no problem getting a handful of SSDs or super fast SDXC cards for the camera if it'll minimize the transfer time. Is your mount (SSD enclosure) powered by the eSATA port (eSATAp)? Or, does the mount require external power to connect to a SSD? If the bottleneck is with the transfer out of the camera, how much faster is the SSD option over, say, a SDXC card spec'd at 300MB/s? SSDs are cheaper now than the 2000x SDXC cards, but there's less gear and bulk involved with internal cards versus an external SSD.
There's an eSATA SSD dock available on Amazon. <http://a.co/d/cOeInnK> Is this similar to what you're talking about having in your lab set-up?
Presuming I'm working with RAW and mostly dealing with 'bullet time' shots, which would only be a second or so in length but at a super high frame rate, what is a ballpark time for transfer out of the camera? 1min? 5min? 20min?
And, how much storage space is required per second of video? Is a 120GB SSD large enough? I already have a handful of 240GB SSDs. Would I need an external array available for offloading the files during a shoot?
The SSD is powered by the eSata port on the camera. No external power required. The cable adapter you need is SATA to eSATA. You can find a bunch on Amazon for cheap.
I can't answer what would be enouph storage for your needs nor can I answer how long the transfer time will be. This completely depends on how much you are recording in one shoot as well as the speed and brand or your card. I have waited anywhere from under a minute to 10 minutes for an export for a shot a few seconds long at about 2500 FPS and varied resolutions. There are too many variables to tell you an exact time. A total ballbark answer, with a good SSD, expect some saving times from 3-10 minutes at about 2500 FPS. (depending on the length)
I hope that answers your question.
