Is there any reason....

OK, so I got a G1 and my plan was to root, etc. right out of the box (being a long time WM user, this sort of thing has become my standard =) ). I have quite a few microSD's laying around so I thought I would just use one of them. After looking i see that the fastest i have is class 4. I see many recommending class 6. My question is this: Is it worth trying to do any of this on a class 4 card or would I be better off just waiting until I have a class 6 card in hand?

I experienced a lot of lag issues when I was using my class 4. Since switching to a class 6 8gb card, it has run as smooth as it did when it came out of the box.

I moved the cache on a class 4 card and I didn't notice a lag so far. But on the other side I don't have a comparison. So, maybe my experience would be far better with a class 6 card.

i moved my apps to my class 4 PNY 4gig sd card and i haven't noticed any lag, i plan on getting a class 6 soon to compare, but on my class 4 the apps moved i have little to no lag. on the other hand when i moved my cache as well there was all kinds of lag, it took the phone 45 seconds to open an email in the gmail app. just saying

That's my worry..I want to move it all there. Right now the phone is quick but I imagine over time, with all that data, it starts to slow (probably sooner rather than later for a heavy user)
Maybe it's just my habit as I always try to run as much as possible from cards (when possible) in order to save the internal for things that really need it while keeping everything working at an optimal rate.

Might as well get a class 6. No reason not to as they are dirt cheap.

Data does not cause slowness. Running processes cause slowness, and this is under the control of the amount of memory available, the garbage collector, and what applications you choose to run.

Quoting myself...
Few days ago I've purchased an 8 GB class 6 memory card (20 euros). Till now I can't see any improvements compared to my former memory card (8 GB class 4).

Memory card keeps corrupting

I have had problems with my hero (the only issue mind you) where sometimes my memory card will corrupt if I turn off my phone - for example overnight or to reset the ram etc ... has happened twice
only big things I have on my memory card is co pilot and spotify (which has offline files on it)
can anyone help - is my hero faulty or is does it happen to anyone else ?
great phone apart from this !!

Not a problem with your Phone.
The problem is with your wallet.
Applications such as Co-Pilot and Spotify use data from the memory card a lot.
Mass transfer on a low grade memory card kills it.
you can use a grade 2 for music and photos but go above grade 4 if using co Pilot.
I know the Grade is normally used for speed but also seems to be for reliability.

memory card
thanks for reply - the 8gb im using is a sandisk ,..... what would you suggest ??
how do you tell if a card is grade 2 or 4 ??
thanks in advance
chris

well ive learned something new, never knew that memory cards had this rating ... my card is type 2 .. just ordered a type 4 off ebay .. hopefully the issue wont occur when i get my new card
thank you for your help kindest regards
chris

Lets hope the grade 4 works better for you
for anyone reading this. the grade is in a little circle after the word sandisk.

I agree with iammodo, nearly a year ago when I got my G2 Touch, I bought a 8GB Sandisk Class 6 from Play.com (£19.99), it worked perfectly and seemed to speed-up any memory card intensive apps or processes, but I took it out for use on another device and bought a class 2 8GB, didn't look worse at first, but then problems started occuring after days of use, sloweness, random corrupts, it even corrupts if I mount it or put the phone off for example.
I recently bought the Class 6 8GB from Play.com and I haven't experienced the problems again.
This is my experience, and probably won't happen to someone else, but at least moving back to Class 6 seemed to fix most of the problems.
I'll probably never buy a Class 2 again, I always go for the highest spec in a memory card anyways. Saving up for a 32GB soon, are there Class 6 versions? If not, I'll wait.

One GREAT WAY to speed HD2 PERFORMANCE

I created videos showing the dramatic difference (before vs. after) but then realized this site does not allow me to upload videos (and I am too lazy to set up a utube account).
The 16GB Micro SDHC card that comes with the T-Mobile HTC HD2 is only Class 2 and is a very SLOOOOOWWW card (also class 2 cards are CHEAP, that is why it is INCLUDED FREE). If you watch the Transformer movies installed on that card you will discover there are a few times during the movies where the screen momentarily freezes. Also if you have alot of songs on the card, when you scroll over to the media player you will see it takes forever for the media player tab (about 45 seconds) to display anything. Even a game that comes with the unit repeatedly freezes and is not playable because of the speed of the card - under games, try the game called "Ferrari GT Evolution". It is a great game but it is unplayable on that card.
I purchased a 16GB Class 6 Micro SDHC Card and it came today. I copied everything from the old card to the new card. WOW, WHAT A DIFFERENCE! It is about $60 but is makes a VERY big difference in performance for everything mentioned above. For instance, the Ferrari game mentioned above does not freeze at all (and loads much faster) and also when I scroll over to the media play tab the delay before that tab becomes useable is only about 3 seconds.
If you want a SAFE great way to really improve the performance of your unit, replace the old crappy Class 2 Micro SDHC card with a Class 6 version. WOW.
(BTW, my main reason for getting this card was also that it took too long to take a photo and then to be able to take another one immediately afterwards. Now that is MUCH faster as well. A workaround would be to not use the card for picture storage but I prefer to put them on the card.)

I have been using a 4GB class 6 card I had laying around and I have seen a difference as well. I copied all the data from the 16GB card to my computer then copied it to the 4GB card to start out with. I saw a big improvement in the momentary freezes that occur when navigating the UI, music indexing and video playback. After using that card for a couple weeks I copied everything back to the 16GB card after formatting it and popped it back in to see if it was a placebo effect. Things were noticeably different, it just felt more sluggish at times. The Class 2 card isn't bad and it isn't the whole problem but getting a better card does change things a bit.
I did pick up a couple 8GB class 6 Sandisk cards for about $10 not to long ago for my camera. The 16GB and 32GB cards aren't as economical yet. The improvement is worth $10-$20 dollars to me but not $60.

how can i tell if my other card is a class 4 or not

It'll be printed right on the front of the card...a little number inside of a circle. If you dont see one there, odds are it's a class-2

Panasonic makes a Class 10...that's what I use lolol...

Class 6 vs 2 Photo... (Micro SDHC Card)
There is no such thing as a Class 10
Look at the photo (CLICK ON THE PHOTO TO ENLARGE IT AND SEE THE DIFFERENCE) FOR THE Speed Class Designation. I guess the standard spec does not say which way is right-side up for printed labels!
Class 6 is the highest speed currently. There are 32GB cards out there (which the unit can support) but they are VERY expensive. The Class 6 card I bought was somehyting like $60 with the shipping from Newegg.com.
Also notice that it is such a damned nightmare to be able to read these ever so tinier labels on everything out there! (Or maybe it's also because of my age.)
It is true, also, that those without the class specification are much older - and slower, I guess they should all be lumped in presumably with class 2

You might want to have a look at THIS and THIS...class-10 16GB cards do exist and are currently available. Jase doesn't usually just make crap up either

Wow Class 10 - !
Sorry, my bad, I guess there is Class 10 now! YIKES! My apologies

PWND!
sweet I didin't know there were class 10 either.
Guess I am going to pick one up soon.

No one is pwning anyone.
Just merely stating the fact.

$100...Hope they become cheaper!

thanks for this thread... i totally didn't realize there were speed diffs on microSD cards.
so a few questions then:
1. the new 32GB sandisk microSD is only class 2... i assume no other manufactures are out yet, especially with a class 6 or 10. this is the very end of the SDHC standard. the next upgrade will be all SDXCs.
2. will a class10 be better than a class 6? i always thought that there are spec. limitations to SD card readers itself. does anyone know what the max limit of the HD2 SD card reader is? class 6 or 10? because if it's class 6, then buying a class 10 would be useless.
i remember that older SD card readers can't read the SDHCs.

1. I haven't seen any class 6 32gig cards but there will be some eventually.
2. Technically class 10 is faster than class 6 but unless you run everything off your sdcard and have a ton of music/video I doubt it would be worth it. If you were going to be using a 32gig card then a class 10 would probably be worth it, though I don't know if the HD2 supports that speed.

Thanks for the "usual" lolol...
To be honest I've got the class 10 Panasonic, and a class 6 Kingston, (both 16gb [32gb models are ridiculously expensive]) and when you run them side-by-side in a phone, there really isn't a difference in everyday use that I can tell. Class 6 is plenty fast for a phone. But there's always people like me in the world who aren't afraid to fork over the extra money to see if the latest tech will get me a little extra speed.
For those on the ropes as to what to get: if your just listening to music, Class 2 is good; for video, class 4 is good; if your non-stop music and video all day everyday work and play, and have some extra cash Class 6 rocks.
For all of you nut jobs like me who care about the extra microseconds of speed, lolololol, and have the money to spend...get the Class 10...
~Jasecloud4

the first thing i did for my hd2 was upgrade to a class 6 from previous experience with rooted android handsets (where upgrade to class 6 is always recommended

would a class 10 or a class 6 improve battery life?

Thanks for the thread and the informative posts, I guess I will make sure to get at least a class 6 for my media heavy device.

Also, if I were to buy one, which companies are reliable? Or are they all pretty much the same? I've only heard of SanDisk and Kingston because I've met the co owner of Kingston and he gave me some free stuff before.

I would just stick with sandisk or kingston anyway, they're both as reliable as any, and usually priced right along the lesser-known maufacturers.

So for anyone who has used both a class 6 and class 10 card IN THE HD2, is there a speed difference? I have a paypal coupon code that is good for 25% off, and am eyeing some of the class 10 kingston cards on ebay which would come out to about $74 with this coupon code. Not very much more than a class 6, course i could just use the coupon code for a class 6 off ebay too. I would like to go the 32gb route, but seems everything 32gb is class 2 =(

[Q]Does class 6 SD card improve freezing

So I've done the regedit deletion for the gsensor.dll but still encountering random freezes. They last about a minute and aren't breaking where I have to reboot but still annoying. Using a froyosense build.
I am using my stock class 2 SD card. I remember reading a few threads that the class 2 would cause freezing on games, even the game demos that came with the hd2.
Will moving to class 6 help the freezing? Any thoughts?
edit: Solved my own issue. Using G sensor lite or changing the g sensor in kernel to off will stop freezing. Class 2 card runs perfectly. Probably a class 6 would improve video/music but thats true of winmo also. Maybe if someone finds my post with the same question this will help.

no i bought a class 6 8 gig , and the only difference i really se is booting android faster and maybe a little better game play

Using a class 6 sandisk and stock class 2 card and I can def say there is a big improvement in stability and performance with my class 6 card. But it is only a 4 gig card.:-(

I am trying to use the 16 gig that came with the phone. It has major issues. The 1 gig card I have works well enough, but with some builds, it's not even enough space! This sucks. How can I even tell what class of card I have? I may buy a 2 gig card because I don't load music and stuff.
EDIT: I figured it out. I see this 16g card has the "2" on it for class 2. Lame.

[Q] Which sd card is better?

So Ive been using the 16gb Class 2 sd card that came with my HD2 for WP7 and I havent really had any problems with it. Occasionally it reboots for no reason, but aside from that, its perfect. However, my friend just gave me his 4gb Class 4 card. Should I keep using the 16gb or reset my phone with the faster 4gb?

simple test, all sd cards work differently
my Nokia 4GB Class 6 is better than may Sandisk 16GB Class 2
Xbox Live Installation: ( only the installation without download )
Nokia 4GB Class 6: 1:23 minutes
Sandisk 16GB Class 2: 9:41 minutes

Class 2 cards usually work better for wp7. Actually class means nothing when it comes to wp7... you want good random access speed for wp7 to run smooth. Many times, the tricks that manufacturers do to their cards to get higher sequential write speeds will actually reduce the random access speed. They don't keep the random access speed consistent on any of their cards as that speed isn't rated, so even cards of the same brand and class can differ greatly from batch to batch. A card made one day may run wp7 well while the same card made a month later may not. So far it seems class 2 sandisk are the most consistent in keeping good random access speed, so if you are going for a card for wp7, go for class 2 sandisk with model numbers ending in A11M. If you already have a card that works well, no reason to switch unless you want to change the size, because there's no way to guarantee a card will work well until it's tested.
