We currently store our photos in a structure like this:
folder\1\10000 - 19999.JPG|ORF|TIF (10 000 files)
folder\2\20000 - 29999.JPG|ORF|TIF (10 000 files) etc...
They are stored on 4 different 2TB D-link NASes attached and shared on our office network (\\nas1, \\nas2, and so on...)
1) When a client (Windows only, Vista and 7) wishes to browse the let's say \\nas1\folder\1\ folder, performance is quite poor. A problem. List takes a long time to generate in explorer window. Even with icons turned off.
2) Initial access to the NAS itself is sometimes slow. Problem.
SAN disks too expensive for us. Even with iSCSI interface/switch technology.
I've read a lot of tech pages saying that storing 100 000+ files in one single folder shouldn't be a problem. But we don't dare go there now that we experience problems on a 10K level.
All input greatly appreciated,
