Bad idea to try this? Anyone else trying it? Footage would be 25MB/sec, some 1080/60p from camcorders and such. No 4K or 50MB/sec.

Computer seems to have TB. Specs for the machine refer to it as a display port though... but it looks likt TB1.0... also has FW800... not sure which is better for video scratch drive. I know TB is faster than FW but this is first generation. Anyone using this machine for Premiere CC video editing?

System:
21.5” mid 2011 iMac 4GB or RAM / OS 10.9.5

Specs from Adobe website:
Mac OS
Multicore Intel processor with 64-bit support
Mac OS X v10.8, v10.9, or v10.10
4 GB of RAM (8 GB recommended)
4 GB of available hard-disk space for installation; additional free space required during installation (cannot install on a volume that uses a case-sensitive fi le system or on removable fl ash storage devices)
Additional disk space required for preview files and other working files (10 GB recommended)
1280 x 800 display
7200-RPM hard drive (multiple fast disk drives configured for RAID 0 recommended)
QuickTime 7.6.6 software required for QuickTime features
Optional: Adobe-certified GPU card with at least 1 GB of VRAM for GPU-accelerated performance
Internet connection and registration are necessary for required software activation, validation of subscriptions, and access to online services.*

Footage would be 25MB/sec, some 1080/60p from camcorders and such. No 4K or 50MB/sec.

AVCHD 25Mbps will be harder on your system than MPEG-2 50Mbps given the needs of CPU power to decode the former over the latter.

Is this iMac an i5 vs i7?

Really, any machine can edit, but it's the rendering speed that means a lot. If going to a 2013 iMac means cutting your rendering speed from hours to minutes, is that worth it to you even if the actual cutting process is more or less the same?

Considering getting the client turned on to this...
