Miners hutWell no self-respecting engineer was ever going to let it rest with that concluding rhetorical flourish!

🙂

Barney kindly provided this addendum to where I left off:

“In this post you pose a great question: the file sizes are much larger, but what price image quality?

Maybe you can inform viewers about this subject please?

Storage cost per RAW image file of 35MB from a full frame 36Mpx camera is 0.3c

The price is extremely low! So low it is not worth your time to go through your folders to clear space.

Calculations:

WD Black 4TB drive with a 5yr warranty costs $309 now (as at July 2015)

A 36Mpx image from Sony A7R has size: 35MB RAW, or 24MB Jpeg

Folder size is 6.13GB for 179 RAW files therefore an average RAW file size of ~35MB is OK to assume

A 4TB HDD has 3.72 TB of available space after formatting (~93%)

3.72 TB/ 35MB = 106285 files of 35MB

Storage cost per RAW image file of 35MB is 0.3c

Also – Seagate now (as at July 2015) produce a $399 8TB HDD for archiving http://www.scorptec.com.au/product/Hard_Drives_&SSDs/HDD-_3.5%22_Drives/58205-ST8000AS0002

Editor's note – not that I've had much success with Seagate HDDs… caveat emptor

Best regards
