I thought about a NAS, but nixed the idea because I back up three PCs over my network, and was afraid that traffic from the remote PC and to the NAS would slow down the process. ; Then I noticed that I had a spare GB NIC on the shelf, which means I could dedicate it to the NAS. ; I guess I'll have to start saving for a Drobo FS (and probably a second GB switch to connect it to the PC).
My photo storage system is very similar to what others use:
H:\pix is the root directory.
The second level is the year: ; H:\pix\2009
The third level is the month number (01-12) followed by either the name of some significant event or "misc" for a catch-all. ; For example, in July 2009 I had shots from the US Senior Open golf tournament, Scott Kelby's Worldwide Photowalk and some other miscellaneous shots:
H:\pix\2009\07_misc
H:\pix\2009\07_photowalk
H:\pix\2009\07_Senior_Open
For a multi-day event, such as a trip to Disney World, I'll create another directory level with the date (although I guess putting the year and month in the date is redundant):
H:\pix\2009\12_WDW\20091202
H:\pix\2009\12_WDW\20091203
Finally, the lowest level has three subdirectories: ; raw (for the original raw images), jpg (for jpg copies of the originals, resized so the longer side is 1200 pixels), and flickr, for anything that I put on my flickr page or otherwise processed.
H:\pix\2009\07_misc\flickr
H:\pix\2009\07_misc\jpg
H:\pix\2009\07_misc\raw
H:\pix\2009\12_WDW\20091203\flickr
H:\pix\2009\12_WDW\20091203\jpg
H:\pix\2009\12_WDW\20091203\raw
I leave the file names untouched, although now that I have three cameras that may become a problem. ; For now, each camera uses its own file name format: ; the D70s uses DSC_9999, I set the D300 to use DS3_9999, and the G11 uses IMG_9999.
