A big benefit to having all your books on the card is they are easily portable between Sony devices, not only the books themselves, but the date added, your bookmarks, latest read, etc.
I had to get my PRS-650 replaced via warranty due to a black pixel on the screen. I popped out the SD card from the old one and put it in the new one and had everything exactly the same. No waiting for calibre to transfer my 2500 books or the Sony to index them.
