All I can say is that, after some testing, I can confirm that putting books on an SD card or Memory Stick makes a huge difference.

I tried with about 1,000 PDFs with annotations. I put them on my 950. On disconnect, it took about 1 1/2 hours to finish 'loading'. I tried three times, and the timing was fairly consistent.

I then put the same PDFs on an SD card (a SanDisk SDHC 2, 16 GB) and deleted them from the device. Now, on disconnect, it's about 2 minutes. I did this about 5 times, it's fairly consistent.

I finally tried with a Memory Stick, by SONY, 8 GB (I think, don't have it here right now, left it home for backup). Same as above - only 2 min on disconnect.

I tried with both the Memory Stick and the SD Card. Took about 4 minutes on disconnect.

Finally, put the PDFs on the device, on the Memory Stick and SD Card. Again, about 1.5 hrs.

With 1,000 PDFs on the device I noticed a considerable delay in opening/closing books (a good 5-6 seconds to return to home screen). When I put the same PDFs on the SD or Memory Stick, the delay was considerably shorter - yet, still, the reader is more sluggish than when empty (maybe about 1-2 seconds to home screen).


I can't explain this. It seems like a bug to me, so I would not suggest everyone should go out and buy external storage. But I have seen others on the forums state the same, so I would look into it, if you truly want to carry around a large number of books.
