Phone crawls when downloading... :(

Does anyone else notice extreme performance drops in overall phone speed when downloading to the SD card from online? I have a 16 GB Sandisk Class 2, just FYI. I notice my phone is ridiculously laggy while trying to use it while downloading a file online to my SD card. Anyone else have the same problem or is this to be expected? perhaps it is not so laggy if I download to the phones internal SD card and not the external Sandisk I have.

Mine does it too. When downloading 2+ apps at the same time the device just crawls. Froyo does fix this as my Nexus did the same thing in 2.1.

same here, glad its not just me, i thought something might have been wrong.

Mine definitely slows when downloading/installing apps.

I don't know about when downloading random files, but my phone would just about stop responding to touch for at least a few seconds when downloading and installing apps, especially if you did more than one. The more you downloaded and installed at once, the worse it got.
Doing the mod moving the data partition to and ext3 partition on the SD card completely fixed this issue.

This is due to the way the phone uses the internal sd card with applications. Apparently 2.2 will fix this but its fixed for me now running jm2 with this fix.
Either wait for samsung to release froyo or dive in and learn some crazy.

SD Writing Speeds

I'm new to this device, and my main problem is that for some reason I can only transfer files to my SD card at around 800k/sec.
I know it's not my PC, I'm using my Samsung stock USB cable, and with my old G2X, using this same cable, I would get around 1.8mb/sec.
is this an issue with the Nexus S or just the way things are with the phone?

No - it seems to be a common thing.
Mine is transferring all my movies back on after a fresh wipe and new ROM at 559kb/s right now.
For some reason it was about 1.2 MB/s last night, but it is slower right now.
I have tried putting it into aeroplane mode, but it has made no difference. I have also tried google searching and reading other forums and it seems to be a common thing with the Nexus S...
Let me know if you find out a way to improve things!

Damnit, talk about a let down. I have a 32gb SDHC sitting at home but I don't think we can swap out the internal storage, can we?
I know on the HTC HD7 there was a way to remove the internal SD card and put in something larger.

If you are on AOKP ROM, go to Settings >> ROM Control >> Startup tweaks. Enable SD Boost and bump up read ahead value.
Otherwise, install ROM Toolbox from Play Store, on the Performance panel, bump up SD Card Boost value. It's reset at boot unless you tick apply on boot.
Goodluck.

Awesome, I'm on RemICS at the moment, but still in the process of figuring out which ROM works best for me.
I ran across some script that increases the SD cache size. Right now mine is set to 1024, but the scripts go all the way up to 4096. I'm not too sure how that translates to the actually mb/sec but I'm going to give this a shot.

If you need faster transfer speeds for larger files, you're better off using recovery. Its an issue with ICS and that is what I've been using for large files.

oohhh yea I know what you're talking about. So it's faster when you mount through CWM?

Yup. Semi fixed issue with ICS. Depends on a few things, like ROM base and kernel used. Just mount in recovery and enjoy normal speeds.

SD-Booster

I've been playing around w/ the SD booster in ROM toolbox and wanted to see what other people were using for settings. I have a 64gb class 10 Sandisk card and bumped up the cache to 1024kb. I mainly use the card for storing pictures, movies, and games.

2048 is thought to be the sweet spot for class 10 cards.

I tried that same setting in my SGS with a 32 get card and noticed no difference. But about 2 weeks or so later, the phone suddenly began giving me messages saying my card was ready to remove. It would come back on and work fine, then do it again. I finally pulled it out and haven't been able to recover any of the 1000s of pictures I had taken.

I've been running 2048 since the first 32 GB class 10 cards came out. Running 64 GB now with no issues. Some of the cards were bad. Others have to do with rom and kernel.

Files gone..

Many of you have compplained about sd card corrupting i havent experienced that but this, morning i woke up to my music and videos, missing from my sd card. I know they were on there because i listened to a song with my headphones on, and when i laid down for sleep i watched 30 mins of a training video for certification test ill be taking next month.
Weird right.

Is this a question?

Lol I meant to ask if anyone has seen behavior like this? That's about 10 GB gone and only 512 mb in lost.dir.

So the files are actually gone? Did you lose everything, or just some of your files?
How are you checking if the files are still there? File explorer app on the phone, plugging in the phone to your PC - or perhaps the best option, pull the card and use a card reader?
Very strange indeed. I've used this phone for 8 months or so - while I've always had the same SD card in it, I've never had data go missing.

I was able to recover about 4GB, it was that little because i copied some files over while getting dressed in the morning (not realizing that files had been lost). The training videos were about 6gb but i didnt really care about those since i have a subscription to cbt. Most of photos and videos are lost now tho. Something told me to dd this sdcard the day before.
I used photorec on linux and recuva in a virtual machine. I put the sdcard in a usb card reader.
The only theory i have is that my battery died because i didnt charge it that night (was at about 30%), and it didnt shut down properly in time. You would think it would have time to shutdown properly but that's the only reason I could come up with.

Slow memory card speeds?

I've been having extremely slow loading times on my class 10 San disk sdcard on kitkat. It takes forever after boot for my music and pictures (if ever) to load.

First,
format it on phone or PC
If u don't want to format, Defragment it on your computer using window's disk defragmenter and you'll see it flying at >>8MB/s
NOTE: Infuse 4G does not support 64GB memory cards. 32GB is the max.
