    So with the last few ROMs I've had installed, I've tried moving apps to the sdcard. I figured it would be a good thing, even if I wasn't running out of room. Welp, that's hardly the case. Every time I move more than just a few apps to the sdcard, my whole phone starts getting laggy. I just moved all of my apps back to phone and the "lagginess" is gone.

    I currently have UD8.0 installed, but it has behaved this way with LFY and Pete's BB ROMs as well ... so I doesn't seem to be a ROM issue.

    Anyone else notice this?

    Weird. I have almost 30 apps moved to SDCard that are supported by the dev, and moved 3-5 more on my own using TiBu b/c of the sheer size of the apps, and I have not seen the laginess so far.

    Still running LFY 1.6, FWIW....

    yeah, I think moving apps will give some lag. makes certain amount of sense: low speed SD card and transhering data back and forth. I have 104 apps and moved nearly every one I could over to the SD card (maybe 50-60) that was not a widget. At times, I have some lag here and there. BUT I use a faster kernel and LauncherPro and that helps as most of my lag comes as apps on the SD card that I have on the home screen lag to load like after I reload the SD card or power boot. But after that, generally all is okay I find.

    since we have such small onboard memory, I do all I can to keep phone memory clear and with 104 apps, I still have 123mb of onboard memory thanks to moving apps and staying on top of keeping the phone clean. since we cannot grow the memory on the phone, we MUST rely on the card and so I do. I think that is just the nature of the beast of a slow class SD card and only have 256 mem and yet wanting to download apps and such. the only future improvement I see is moving to a faster and bigger class 6 32GB sd card.

    I have many more apps than that, more like 160+, and I am always hovering around 20-30 MB free.

    Also, there have been numerous discussions about how a Class 6 SDCard will not make that much of a difference b/c the hardware is hardwired to use Class 2 speeds. At best you get slightly better than Class 2 speeds.

    Finally, if you move apps that are used on a regular basis, I can see lag occurring, but if they are not used on a regular basis, then regular use of the phone (excluding use of said moved apps) technically should not cause lag in the first place.

    never read that. did not know the hardwire had a built in bottleneck. I guess I assumed the throttle & access speed was determined by the card's access rate and not by a hardware limitation on the phone.

    I wonder how proven this is. For example, at the time of the D1, I do not think people knew the chipset could go faster than the 400mhz (??) advertised. But then we found out the chip actually had a software governor on it and once that got lifted - with things like SetCPU and faster kernels - a different world opened up. So, hardware that was locked down was opened up due to software settings and thus, I wonder if the same can be for a r/w speed on the card to maybe access faster than class 2?

    I have also read all these discussions, and I have to say that I'm probably the ONLY person on the internet that disagrees. It's my opinion (and obviously ONLY mine) that a higher speed class SD card WILL be of benefit on the original Droid 1. Maybe there's no benefit from Class 6, but there is from Class 4.

    My justification? I installed a Class 4 card, just for fun, and ran the Market App called "SD Card Speed Tester." I got just under Class 4 speeds. This is an actual read/write to the card, via a phone-based app, so why wouldn't everything utilizing the SD benefit from this higher-speed card? A Class 4 card is about twice as fast as Class 2. That is not trivial. Thus, I do not agree that the phone's hardware is specifically bottle-necked to Class 2 speeds. More like Class 4 speeds.

    When I reinstalled my Sandisk 32Gb card, I got just slightly under Class 2 speeds, which is consistent with most other users. This card is a snail. As Lock-N-Load mentioned, my biggest frustration is that LauncherPro boots WELL before the SD card is mounted, so I have a bunch of unlinked icons (and apps) after booting. Requires a LauncherPro reboot a few minutes later.

    Also, the slower 32Gb card sometimes causes fits when installing zips (roms/kernels) from within Rom Manager. That always works fine when installing directly after booting into recovery, though. Neall

    I have the 32GB card and I have lots of problems with it mounting in recovery, even when X-Booting manually. Glad to now have a clue as to why. I can deal with it but it pisses me off since I spent about $120 on it. I wouldn't dream of going back to 16GB though :)

    Come to think of it... you're right. I usually have pretty good luck doing an X-Boot into recovery, but it doesn't always work perfectly. Sometimes recovery (I use clockworkmod) will freeze in this way, and it appears to be (again) related to the 32Gb card.

    Perhaps worst of all, I had the infamous "phone reboots on SD card mount," whereby the darn phone would reboot when mounting the card manually or when unplugging USB after a PC transfer. VERY annoying. I got around that by doing a FAT-32 SD card reformat using stock parameters on a Windows XP machine. It hasn't caused a reboot since. Still, the 32Gb SD card is DOG SLOW. And those with desktop linux experience also know that mounting a larger card takes more time in and of itself, compared to a smaller capacity card. Thus, a slower, larger capacity card just adds insult to injury when it comes to mounting time. Neall
