I think I need to re-imagine my storage solution.
Sometimes none for weeks, sometimes a thousand a day (especially when it's for work). It always depends, I am rather trigger happy when I've got the camera out (it has gotten less though... I'm holding back and try to think more, compose more...).
All in all I have roughly 216k photos, residing on one hard drive. I've bought 2 4 TB drives, which I wanted to use to do a RAID 1 with the drives so the photos would be there, but unfortunately my TV show/movie collection uses up one of them. Will have to buy another 4 TB drive I guess... maybe in October. And eventually I'll build a proper NAS... The photos are backed up on a cloud backup service though, so I'm not too worried.
K-5, so the 16 MP do help. Good photos get compressed again as lossless DNG (saves maybe 10-20% compared to in camera DNG or PEF), same for photos that are noisy, i.e. above ISO 6400 perhaps. The rest gets compressed as lossy DNG, which gets the photos down from say 20-30 MB down to around 5 MB. You can still edit the photos properly, to be honest I haven't seen a difference to proper lossless DNG files. Lossy DNG is less efficient with noisy images, you may end up with files that are bigger than the lossless ones. That's why I only use it on low ISO photos.
I tried a K-1 photo I've taken at a store, ISO 400. As lossless DNG (unfortunately I don't know how big the original file was) it was 33 MB, which isn't much bigger than my K-5 files... Compressed it using lossy DNG, now it's 9.4 MB. I think that is absolutely manageable. I also took a 47.2 MB big (ISO 400) sample file from... imaging resource? Compressed lossless DNG it went down to 41.5 MB. Lossy DNG it is 12.2 MB. That's less than in camera JPEG files have...
