Hi Guys, Can I do 8 ISO recordings on a System with 6700K CPU, 1080 Graphics Card, 32 Gigs Ram, 1 x 1TB Samsung 950 PRO M.2. Recordings will be mpeg .ts 720p at 25Mbs. Can this be done? Would it be better to use 2 Samsung 950 PRO and record 4 ISO on each? No Streaming or Program Recording will be done on this system. Has anyone done this many ISO?
Maxi

I don't think so, I can get 7 iso's on a 6-core Xeon E5-1660 running at 4Ghz.

Maybe if you used simpler codecs and transcode later if required. Win Media was always very efficient, possibly MagicYUV but it eats space, Mjpeg, there's also the I frame only Prores available with FFmpeg.
VLC may have more options.

What about an i7 6900K with X99 MB? Anyone tried this? How does that CPU compare to the E5 1660?

Little known fact, if you install the free NewTek NDI Tools pack this will provide a new codec option for vMix AVI recording called "NewTek SpeedHQ 4:2:2".
This is the same compression used in NDI and is very CPU efficient and it should be possible to record up to 8 on a 6 core processor.

Well iOS recording will need hard drive speed more than anything,so if u have a raid with 4 ssd's in a raid 0 configuration called stripping so all drives act as one and 4 times faster,I hit around 1700 gb per sec,also another option is a pcie ssd card ,and some of them can hit 2 gb a sec,,,,,I have never tried more than 4 iso at once ,,but in audio performance I can play more than 1500 audio tracks.....hmmmm wow!!!

A single SATA3 SSD can do 500 MB/sec write these days, More than enough for 8 times 13MB/sec = 104MB/sec for the NDI recording, or 8x 35 MB/sec = 280MB/sec for MagicYUV. No special storage needs...

No special storage needs... Agree but I would probably use two SSDs, 4 on each, not so much for bandwidth but for redundancy. You could also record a camera or two using the camera's internal card. Check these out, 4 x M.2 striped, 9 GBs, not that you need it for this application - https://www.servethehome...the-hp-z-turbo-quad-pro/http://www8.hp.com/us/en...ns/z-turbo-drive-g3.htmlNow if the PC clock could jam sync the timecode track on all the recordings and the SDI ancillary TC track ...

To answer my own question: Yes, it also installs support for Premiere. This has a big chance to become the new recording format I will use from now on. What about fault tolerance?
