How Do I Store My Pictures

I have three copies on three physically separated medias. The chance that all of them crash at the same time is almost zero. It's important not to use the same disk and different partitions because if the disk would e.g. be physically damaged you loose all your data at once.
I do not trust optical medias like CDs or DVDs so I use three external hard drives (USB and Fire Wire). They became really cheap these days.
I sort the pictures out into folder named by year and then subfolders yyyy_mm_dd_description.
My idea is to mirror all my pictures in some kind of "thumbnails" in monitor-resolution-size on my laptop internal hard drive.
All this work I do manually.
