Age Old question -- SD card vs internal memory
Cuz this was addressed in a couple other threads, but isn't strictly on topic for any of them, I thought I'd just stick the results of my little experiment out here.
Should we use the SD card or internal memory. Which is faster? Why one over the other?
Lots of theories there, but I didn't see actual figures, so...
Hooked up my Astak PPro via the USB cable, dragged and dropped the Astak "500+ Free eBooks" folder (about 250m) from my computer to the internal memory, then to the SD card, deleted both, then stuck the SD card in a card reader and did the same.
USB cable 250m file folder:
To int mem = 6 minutes. Delete same, 2 minutes.
To SD card = 3 minutes. Delete same, 20 sec.
SD Card in card reader:
To SD card = 1 min 20 sec. Delete same, 15 sec.
Hope it helps some. Naturally, results will vary depending on each person's equipment.

What I don't understand is the long delete times on the PEz?
Delete is really a "Mark Deleted/ space is Available" or a Move (the directory entry) to the trash folder (one for each storage device).
The file should not change position in the Flash, therefore only take seconds to re-write the directory entry and FAT table
Your times in the Card Reader are what I expected.
