[Q] froyo apps2sd and card speed - Nexus One Q&A, Help & Troubleshooting

currently i'm using a class 6 8GB card but i'm thinking of upgrading to a 16GB.
however, all the 16GB cards i see are class 2. now i got the class 6 because i was using apps2ext on CM5 and 6, but since i'm getting a tablet, and more and more apps are getting froyo apps2sd support i'm not going to need apps2ext anymore.
So i'm just wondering if dropping from a class 6 to a class 2 will have any effect on the way froyo handles apps2sd.

Frankly the froyo apps2sd is pretty bad. It does save some space, but in the end it's a game trying to uninstall this to add that. I have a class 4 and can't tell any difference in speed with apps2ext, even with dalvic2sd.

Class 2 sd card with apps2sd slow?

Is the fact that I have a class 2 sd card with apps2sd slowing me down so much that games like papijump or abduction are slow and unplayable? same thing with my desktop and the touch screen.
i'm rooted running CM 3.9.7 or whatever the newest is.
When I re-flash it seems to be fast again. I'm just trying to figure out whats causing my phone to lag on this fast rom.
I'm running ext 3 and no swap file.
More then likely..
Ya id say the a2sd on a class 2 is probably gonna bog the crap out of your phone. The reason people recommend a class 6 is because of the speed. Class 2 just cant move data fast enough to keep up. Get a class 6 or keep the apps on the phone.
Also this is just my theory. I could be wrong.
Yep class 2 you will experience lag. Get a class 6 they only $15 on newegg for a 8 gig.

HELP Memory Card Dead

Hey Guys,
Was running CM 5.08 on my Dream.
My class 4 memory card died.
My class 6 memory card is still on its way (shipping).
(don't know when I'll be getting it).
In the meantime. I'll be running on the class 2 mem card that the phone ships with.
Any suggestions on what rom I should be running?
(probably won't want to be running APPS2SD or Swap)
So probably want to run a rom that's nice, trim and snappy.

Take your pick. You shouldn't be using swap anyways. Apps2sd won't hurt -- it'll just *might* run external applications slower than they would internally. Note that the SDCARD's CLASS is not an indication of its MAXIMUM speed -- it is an indication of its MINIMUM speed. A lot of C2 cards are actually FASTER than a lot of C6 cards.
thanks for your response.
speak of the devil.
my new transcend memory card just came in the mail.
Still would be a good thing to know for future's sake.
Is it true, that I shouldn't be running swap? What does that mean? Feel like most people run their Dream / G1s with swap.

SD class 10 slower than stock SD card?

I bought a Patriot 4GB class 10th micro SD card for my Hero. I was transfering music to my phone and I noticed it was only going a little above 2 MB/s. I thought that was a little slow so I ran CrystalMark benchmark and got the same result write speed.
To make sure it wasn't my phone, I put the class 10 card in my girlfriends completely stock hero and got the
same exact results. The stock card gets more than double write speed.
Now, taking these cards out of the hero and using a adapter and inserting it into my laptop, results are much better. The class 10 card is outperforming the stock card by nearly double.
Anyone know what's going on?

The Hero only recognizes up to class 6. If you buy a class 10 sd, it will work, but you'll have the same speeds as a class6.

This would be my guess. I'm assuming your stock was a class 6?

I'm not sure what my stock SD card is but people claim the stock card is class 2, though mines performs like a class 6.
if the Hero only supports up to class 6, does that mean a class 10 will perform slower than a 6.
I rooted and installed nfinite's .7 ROM on my girlfriends hero. Our phones are now identical except for the SD card. While transferring music back to her phone, I noticed it was going even slower than mines, around 1.85 MB/s. Looks like it's the ROM causing the speed issue, hmm.

The stock 2gb card that came in my hero was a class 2, and my hero was purchased a week before the evo came out. I put a class 4 8gb card in the phone and it runs fine... I was going to purchase a class 10, but I'm glad I didn't now.

Just to be clear, it was the ROM which was causing slow SD card performance. I'm now using aospMod and I'm getting nearly 6 MB/s write speed.

[Q] MicroSD Question

Just picked up my NC at Best Buy about and hour ago. I have it at home charging and I'm going to go get a couple of MicroSD cards.
Should I go for the Class 10, or is Class 4/6 fast enough?
Unless your running something from the SD card then I'd recomend at least a class 6, you'll get around 11mb/s writing time, otherwise both the ROMs for the nook (Honeycomb & Nookie Froyo) both support installation to the emmc, you can just flash them to your system with Clockwork Recovery.
tldr; if you can find a class 6 or higher for cheap (I got an 8gb class 6 for $12 off amazon) get it, if not you'll be fine with anything truly now.
I am currently using a Class 4 8gb, and have no trouble running apps or even Froyo off the SD card,
Basically if you are just using the SD for apps or holding data, anything should work i would recommend at least class 4 or better, if you are going to be running the a custom rom off the SD while some class4 will work well. I would still recommend class 6 or class 10, Faster is always better.
Posting this from my new NC!
I stopped by Frys Electronics after dinner and picked up two Patriot 8GB Class 10 MicroSD cards. Getting to know the Nook a little before I root and start with the custom ROMs. Gonna load Froyo on one card and Honeycomb on the other so I can try out both flavors and see which one I like better.

Which microSD card is the MOST STABLE and FASTEST for using HoneyComb in SD card?

So I finally got HoneyComb working on my Nook Color (NC), residing in the microSD card using a Kingston 8GB Class 4. However, this card seems to be one of the slowest and using the HC in NC is almost unusable.
Example:
- Screen rotation takes 3-5 seconds
- Opening new app, depending on which app, can take 1-5 seconds
- Browsing certain website can make the screen unresponsive
- etc..etc..
I know that the HC version available in this website is probably still in "preview" or beta stage and some slowdown is expected, but I am not expecting it to be THIS bad. So I think the culprit is the microSD card itself.
However, I have tried many different MicroSD card and none works. I.e. it gives the "decrypt storage" error when booting up the NC. The cards I have tried are:
- Patriot 16GB Class 10
- A-Data 16GB Class 10
- Kingston 8GB Class 6
The ONLY one that works so far is Sandisk. Unfortunately, from SanDisk website, I do NOT SEE ANY card higher than Class 4.
Thus, can you recommend which is the MOST STABLE and FASTEST card? I.e. the ones that did NOT give slowdown per the examples I have given above.
i'm using sandisk 4 GB class 4 HC
nookie froyo, runs fantastic.
Class 10 cards apparently dont do too well. lots of people have had issues with those. class 6 should be OK, class 2 and 4 workk very nice.
Do you have recommendation for a good Class 6 MicroSD card? SanDisk don't sell anything higher than Class 4. I tried Kingston Class 6 and my Nook Color just spit on it...

I am currently running trancend 8gb class 6. Havent had any issues with froyo, HC or Cm7 booting or running.
I'm using a A-Data Class 6 16Gb card with no trouble. I do have 2 Kingston Class 4 32Gb cards and they have the issue with the decrypt garbage when you try to boot up HC from the sdcard. I've also got a Class 10 32Gb Wintec card which I have not had time to test out yet as I just got it the other day.
After a failed Kingston 16gb class 10, I got a SanDisk 8gb Class 4 and it's speedy enough. I notice very minimal slow down on some menus but I don't know if that's just the OS itself (being a preview after all)

That's the exact same card I have, and you did NOT experiences any of the slowness I posted in my 1st thread?
How drastic is the difference between Class 2 and Class 4?
I know that it says that it processes twice as fast, but is it noticeable? Can somebody give an example of when you can actually tell the difference? Playing music, watching movies, booting from microsd?
I have a Sansdisk class 2 8gb card that performs just as well as my class 10 Patriot 8gb (which has booted both HC and currently used as storage for my eMMC CM7 install.)
Sansdisk severely underrates their SD's and many other manufacturers overrate theirs. It is not a perfect rating system.
I would recommend going w/ sansdisk in whatever size you can afford. Class 2/4 will be plenty fast.
Before I switched back to Froyo I was running off the SanDisk 8Gb card from BestBuy - $20 - which I found very responsive. I think it is Class 4, but I could see any label on the card itself or the package.
The SD card speed was not the reason I switched back, it was the lack of other features in HC preview. I can't wait for an AOSP release
8GB Cards
I currently have 2 8GB microsds that I switch between:
-Transcend 8GB Class 6 running Honeycomb from Amazon. Tested it with h2wtest and got 16MB/s write and 14MB/s read. (Not sure if that is a typo on the tool or not and it's supposed to be bits instead of bytes, but that's what it says).
-Sandisk 8GB Class 2 running Nookie Froyo. Tested at 14MB/s write and 18MB/s read.
Both cards run their respective ROMs well, so it seems to jibe with what chisleu said about Sandisk underrating their cards. I could also be limited by the USB adapter I was using, but I had another adapter that was limiting it to 4MB/s both ways.
