As far as I remember correctly, on average it has enough write cycles that you should be able to write to it *constantly* for tens of years. I doubt the rest of device will last that long. :-) Except for RSS, email etc refreshes which results are stored under /home/ and operations for files on /home/MyDocs, there shouldn't be much writes to it though. If you have Flash enabled in Browser, but no memory card, the video streaming is buffered on that too. Real reason for avoiding frequent writes / disk churn on rootfs is that this would trigger JFFS2 garbage collecting much more frequently which can *really* slow down your device: https://bugs.maemo.org/show_bug.cgi?id=2615 The internal 2GB memory card in N810 has less write cycles than the roots. Because it's larger, it can spread the writes over more blocks i.e. wearing shouldn't be a problem for that either. Btw. Personally, I wouldn't enable swap on it (from Control panel) though, at least constantly, for following reasons (ordered from more important to less important): 1. with constant swap file writes, it's much easier to accidentally cause the card FAT file system to get corrupted 2. there's a performance slowdown (although swap allows running some use-cases that wouldn't be otherwise possible) (3. Flash wearing) If you want swap, I would suggest a fast SD card with a separate _partition_ for swap and some hacking on the device startup scripts to support this. - Eero _______________________________________________ maemo-users mailing list maemo-users@xxxxxxxxx https://lists.maemo.org/mailman/listinfo/maemo-users
