Is a class 6 really worth it? - G1 General

Hello all, sorry if this has been asked about before, I tried a search and didn't come up with much. Basically, I'm using a class 2 2gb microSD card and was wondering just how much of a performance boost I can expect to see from roms such as SuperD (1.6) or OpenEclair (2.1).
I've heard good things but never a definitive comparison (video or the like) that shows just how much better a class 6 is.
Thanks

yea its been asked a couple of times and everybody says its a must have if you like speed and smoothness. Getting one has been on my to do list too long lol.

I'll reiterate, yes.
Class 6 all the way!

I'm pretty sure Class 6 or greater is only needed to use A2SD properly. So if you don't use it, I don't think it'll make much of a difference. I do know that Class 4s can be considerably cheaper. Like the 16GB Sandisk that went on sale for $40.

There's greater than Class 6 for Micro SDs?! I got a 8 GB Class 6 from Newegg for around $20 so that was pretty cheap and 8 GB should be more than enough unless you plan on loading the card with movies.
Also, people say Class 6 is a must if you plan on using the Hero roms.

I've used A2SD before, and yea, it was rather slow compared to stock.

I've tried Hero/Sense roms before and everything besides the home screen was agonizingly slow, so if this will make it usable (or dare I say, fast?) then I guess it is worth it..

Anyone sourced a 16GB microSD class 4 or 6?

Looking for a 16GB microSD for the Hero.
Anyone sourced a class 4 or 6? or indeed, have you used a class 2 and happy with it?
many thanks all
I have a class 2 16gb in my G1.
Apps2SD and Swap runs fine (Using JacHeroSki Hero rom).
I don't see what the class thing is all about, applications run as speedy as if they were installed on the device itself.
http://www.lowpricememory.co.uk/Sandisk-16gb-micro-sd-memory-card.html
Only used the 2GB card Orange bundle with the phone, and am experiencing a bit of sluggish perfromance on the home screen occasionally - someones said that this is solved by a faster card but will have to wait and see - got one on order.
That link you have posted says 'Class 2' in the write up but the picture is 'Class 4'.
I looked at that earlier and that discrepancy put me off ordering it.
Heres a class 6 16 GB....

Yes it would. WE HAVE A WINNER, 1 class 6 16gb.
These are still quite expensive though, I'd be tempted just to stick with an 8gb class 6 (which I got for £11 GBP) and when I run out of space, then move up to the 16gb
They will not ship to the UK (unless it's a copy of WoW you are after!)
But good effort!

yeah 16 GB too expensive for now for me, got an class 6 8GB card at £14 on order, as soon as the 16 GB cards are cheap enough I'll grab one, I can wait.
After much googling, I decided to get a class 2 from here:
http://www.carphonewarehouse.com/ph...ANDISK-MICROSD-16GB-CARD#handsetDetailsHeader
It seemed the transfer rate was not that key on our devices, as class 6 was well above what the phone could manage.
It could all be nonsense and I end up getting another in a few weeks

N1 and memory cards

i was wondering , since there are all sorts of micoSD cards out there , from your experience , N1 users , which card will be the best:
1. a 16 gb class 2 , probably sandisk?
2.an 8 gb class 4 or 6 , again sandisk?
i'm asking if you could feel any real difference when you use a class 4 or 6 watching videos or listening to music on it , in comparison with the standard class 2 card that comes with it
cheers
I'd probably go with Class 4 as the minimum. You will find most people here have pushed for Class 6 since we were using the card for Apps2SD (installing applications to a Linux partition on the card, rather than using internal memory) on the G1/Dream and myTouchMyself3G/Magic. The faster the card, the better the apps performed along with the Android OS itself. I still prefer the faster card when using gallery and other apps that scan the card for media and write a great deal to it (like Subsonic).
I have an A Data 16GB class 6 unit I got from Newegg for $50 with free shipping. It costs more now, but it will likely come down again:
http://www.newegg.com/Product/Product.aspx?Item=N82E16820211378
I have Sandisk class 6 cards that transfer at 20MB/s write and 25MB/s read, but those were my 8GB units. I didn't benchmark this one as it seems to be fine.
I have two 8gb class6 and and a 16gb class2, i use my class6 cards in the phones I use the most, can i tell a huge difference in speed in everyday use? Not really. But Im still gonna get a 16gb class6 because it does feel just enough faster to make it worth the money.

oh , but you do say it actually is different? i mean , from what i know , for a card to be faster , the other hardware parts and specially the OS itself should be capable of reading and writing things as fast.
but you do say it make a difference?

no the OS will execute the "write" or "read" command and the sdcard will be accessed at the max speed allowed by the sdcard itself.
I wouldnt personally use a class2 if possible, tho with Nexus's good amount of ram, any slowness would probably be less noticeable.
thnx guys , so i'm guessing i gonna buy me a class 4 card

Dunno how much space you need but I just bought a 8G CL6 for £13.99 from amazon.
You can get a 16gb class 6 on newegg for 48 bucks. Know it's a little pricey, but it's the best of both worlds.
thanks Mi|enko , but i live in UK , so if i order from US , i would probably be surcharged by import tax as well , at least that's what i know
thanks Abbsta , that sounds about right . i will try it in a bit. cool mate.

All these new features make me realize I need a new faster SD Card.

So where is the best place to order one from?Any brands to AVOID? Is the sweet spot money wise 8 GB? I'm talking class 6.
Man I ask a lot of questions.

Depends, how fast are you looking for?
I picked up 2 Transcend 8 gb Class 6's on Amazon for 17 bucks each.
I figured its not kingston or san disk but hell 17 bucks is cheap.
Not to mention I have a transcend Flashdrive and transend ram in one machine, it can't be that bad.
I ordered them tuesday, haven't gotten em yet. But I'll let you know how it does monday when I get them. They are actually probably waiting at the office for me....damn I should have had them shipped to the house instead...thanks for making me realize I am a moron. errrrrr....
EDIT:
I have heard TopRam stuff doesn't last, but there is a lot of it out there for cheap. Could be a good alternative if you don't mind buying stuff 2 or 3 times. reviews tend to be negative, or at least highly mixed with them.
The transcends seem to be sold out Thats a good sign.
good question
I would also be interested as well. I'm using stock card that came with the phone. I'd like to move up but don't want to over pay.

I guess I told too many people about the steal of a deal.
I got the Transcend 8gig from amazon.. No problems at all so far....
I too am using a Transcend off of Amazon. No issues here, and I will always go class 6 or higher from now on in any of my devices to ensure that I don't get hampered by speed. No issues on any of the ROMs, and I tried just a few out today, to the point everyone was asking what the heck I was doing to my phone.
+1 transcend on amazon class 6. it is greeat.
I've had no problems with the Transcend I purchased from Amazon
Got my new Transcend SD's today. Anyone know of a good app to test the speed? I have seen some benchmark stuff on the forum, but I am not sure what they are using to get their numbers.
What I've been using to benchmark my phone's speed is the app called 'benchmarkPi'. Speeds under 9000ms are pretty good.
Edit: app name correction
I got the Transcend 8gb class 6 off of newegg website. $19.49 with free shipping. Works great. Model TS8GUSDHC6.
*I also use Transcend RAM in my desktop computer and never had any issues.
Easy way to test the speed is to copy a large file from you computer to the sd card. It will show you the transfer speeds as it copies. The Transcend 8 GB I have will sustain 12-13 MB/s copying a 300 MB file to the card.
Look up crystal disk, it will give you a benchie of the card (in windows of course).
Not sure how great it is, but seems like a decent deal: http://dealnews.com/PQI-8-GB-Class-6-micro-SDHC-Card-for-15-free-shipping/361308.html
PQI's a known memory name. I bit on the 8GB transcend on the egg.
According to a few benchmarks, at worst case scenarios, PQI barely exceeds the Class 6 read speeds (at which isn't bad), but it also barely exceeds Class 2 write speeds (which is really bad!). So I got one for $15...
But PQI is known to had write speed issues in many of their flash products.

Try Newegg. Bunch of 8GB class 6 cards for around $20 (if you can't get any Transcends...I think they have the Transcends for around $18-$19.

Thanks Transcend just ordered. from New Egg.

Ordered my Focus!!! - Micro SDHC Question

I ordered the Samsung Focus with Amazon Wireless for one penny and a two year contract with AT&T! Couldn't be any happier with that.
Anyway, I ordered a case:
http://www.amazon.com/gp/product/B00495YF8A/ref=oss_product
And a screen protector (I know it's tough to scratch but eh, why not. Lol)
http://www.amazon.com/gp/product/B003F8C1GK/ref=oss_product
So I've been thinking about how much memory is on the phone. 8GB is nice but I will want to put a few of my 720P movies onto the Focus. I figured I could get 8B Micro SDHC (Class 10) and it would make it, 16GB. That's pretty decent, right? I think it will hold me over... Lol.
I did some research and I get the higher the class, the higher the write speeds. Right?
Well, what do ya'll think of this one?
http://www.newegg.com/Product/Product.aspx?Item=N82E16820220493
Thanks in advance everyone!!!
8gb is good enough for me....for now! Ill be buying a 16gb card soon enough tho because everytime you change the sd card you have to do a full reset on your phone, so id rather just do it now and get it all over with. So, what im trying to tell you is just get yourself a 16gb card if you going to be adding 720p movies...that way you wont really need to worry about changing the card later. As for the class...class 10 is unnecessary....class 2 has been proven to be VERY sufficient in the focus...even class 4. I had a class 6 and now I have a class 2 and there is NO difference in performance on my focus. Anyways, as for sd cards, be careful because some aren't working properly....I would say your safest bet is buying Sandisk...since thats what Samsung is using in the focus for memory right now.
Hope this helps!

Well, if I put a 720P movie on there, I'll just delete it once I'm finished watching it. Not going to have more than a few gigs of music too. So 8GB is good for me. Obviously once you put a movie on there you can delete it and get your memory back, correct? Sounds nooby but just double checkin... Lol. The higher the class the faster it gets on the card, right?
sd card
i got a sandisk 16g class 4 from radio shack cost about $34, had it in since two weeks before christmas.... loaded it almost full, empted most of it out loaded and unloaded stuff, havn't had any problems so far....... been running strong and just as fast as without the card...

correct...once you delete things you get your space back. I didn't notice much difference in transfer speed between my class 6 and class 2. So if you can, just save yourself the money and get class 4. There was an article I read somewhere that a higher class can actually make performance worse on the phone. Don't know how true it is, but class 2 has been perfect for me. No difference anywhere.
You need too spend some time reading this thread before buying a microsd card:
http://forum.xda-developers.com/showthread.php?t=834144&page=3
Determining whether an SD card is Windows Phone 7 compliant is not a simple matter of judging its speed class. Several other factors, such as the number of random read/write operations per second, play a role in determining how well an SD card performs with Windows Phone 7 devices.

A higher speed class can actually work against you because sometimes the maker sacrifices random operations for speed.
You can either wait for official "windows phone 7 certified" cards or take your chances. Read the first post carefully, especially the most recent posts. I personally have been using a 16gb Samsung card with no problems. Caveat emptor.

Patriot Signature 16GB Micro SDHC Class 4 Flash Card Model PSF16GMCSDHC43P

If you read the feedback, nothing but positive reviews.
"Pros: Very good price to performance ratio. Works with the Samsung Focus. Good read write speeds.
Cons: None
Other Thoughts: Not sure why some say negatives about the speed of the card. Maybe they got a bad one, but this tested out at just under 4.5gb write speeds. I had been using a Sandisk class 2 card with my Samsung Focus, but it would do some random rebooting and crashing. With this card it has been absoulutly perfect for over a week of use. I have 15gb of music and photos on the phone so I know that I am using the memory card along with the 8gb that is onboard with the phone."
Kinda sold on this... Should I do it?!?!?!?! Buy it right now?!?!! lol
This is pretty much what I was asking in another thread. I want to go with a 32GB card as I don't want to go through hard reset if I ever need more memory later on.
What is a good 32GB tmicroSD card hat works with Focus with no issues? I would like name of manufacturer, class and even the part# so I can source locally (go to store or order online).
Thanks.
No lie, you're going to spend a lot of $ and 32GB is overkill.

After reading the large thread on compatible cards above, it seems the real test is if you've loaded over 8GB of data onto the SDHC card (or over 16GB total in your case) and don't experience any problems. If that's the case then that's awesome (and it also sadly verifies the fact that no one knows which brand of card really works than the Sandisk 8GB Class 2, which is mentioned in the official instruction manual).
To the OP, I've stuck with the 8GB Sandisk. I considered the OEM version for $12 USD available on Amazon but decided against it, and went with the retail packaged version, which I got at Radio Shack for $20 USD. 14 or so GB will be good enough until the official certified ones are announced.
well ill just refer to him as mr arse... but mr arse is partially correct.... mine was stable up to 15gb then after that it went downhill fast.... so give the dude a bit of a break....
Has anyone seen any OFFICIAL announcement that there will be APPROVED cards for WP7. I know that Sandisk tried to pull a fast one and say their's were approved but then pulled them. Is MS even allowing such a program?

Micro SD Cards

Ok, so I know this is a topic that has been really over-discussed, but I really can't seem to find very much good information online, so I turn to my most trusted authority...XDA with a few questions...
I currently have what I believe is a genuine Sandisk 16 GB Class 2 microSD card. And from reading in the forum - I realized when I upgraded (in the meantime I reverted back...) to CM 7.0.3 I had serious lag issues, and I understood from different posts that it was because I needed to upgrade the class of my SD card. In the interim, I've purchased a Sensation 4G (which I have yet to receive - but expect to have by Wednesday). I know this phone comes with an 8GB card - I'm just not sure of the class - but assuming that the phone records HD video - they should have the sense (no pun intended) to provide at least a class 4 SD card right?
Here's the thing. It's really hard to understand - even from reputable stores, which SD cards are real and which are fake.
General questions:
1) Why do some cards have their class marked on them and some don't? What does this mean?
2) There is no standard look to SD cards even from the same company. How can I know where to buy a real one?
I already got burned by eBay - so I'm not going down that route again - but even NewEgg and Amazon (where I bought this card from and am happy with...even though I'm no longer sure it's even real. I downloaded an app that's supposed to test read/write speed and authenticity - and it didn't say Sandisk, so now I don't know...Despite being a class 2 card with write speeds of higher than 6 MB... so I really am confused. I'm assuming a fake card would cheap out on quality...)
While I always prefer to pay a bit more for the best - and from what I can see there is no consensus regarding any SD cards besides Sandisk/Toshiba/Samsung, however - there are no SD cards from any of these brands to be found online for purchase with a class higher than 4 - besides class 10 that costs somewhere in the vicinity of $100 (which I am currently unwilling to pay).
1) Is there no Sandisk Class 6 or 8 card?
2) Why can't I find them anywhere if so?
3) What is known about companies such as Kingston/PNY/Lexar/Transcend - what I've seemed to find is that the good reviews are great - but the bad ones are REALLY BAD. Do I want to chance getting a lemon and losing something as precious as photographs??
4) What about reputable companies that aren't necessarily known for their memory/SD card strengths but other areas - Duracell, HP, Panasonic, Nokia?
5) Would I be better off downgrading to a smaller card with a higher class? (i.e. 8GB Class 10?)
I'm really confused - any and all help would be very much appreciated.
Thanks!!

It's not so much the "class" of the card, but the real-world performance of the card. I've seen class 4 cards preform better than some class 6 and higher cards.

2) There is no standard look to SD cards even from the same company. How can I know where to buy a real one?

There is no way to tell a fake one from a real one by just looking at it. to be safe, buy one from a brick-and-mortar store, where it is easily returnable. Don't buy it online unless it is from a well established retailer like Newegg.

While I always prefer to pay a bit more for the best - and from what I can see there is no consensus regarding any SD cards besides Sandisk/Toshiba/Samsung, [snip]

Why makes you think those brands are the best??

1) Is there no Sandisk Class 6 or 8 card?
2) Why can't I find them anywhere if so?

1) Not sure, but I'm sure if there is, it would be listed on their website, or one of their CS reps would know...
2) Call the company (or look on their website) to find out...

3) What is known about companies such as Kingston/PNY/Lexar/Transcend - what I've seemed to find is that the good reviews are great - but the bad ones are REALLY BAD. Do I want to chance getting a lemon and losing something as precious as photographs??

I personally would group all four of those companies you mentioned in with SanDisk at the same quality level, but that's just me...

4) What about reputable companies that aren't necessarily known for their memory/SD card strengths but other areas - Duracell, HP, Panasonic, Nokia?

As you said, they don't specialize in flash memory, so chances are their products would not be as bleeding edge as SanDisk/Kingston/PNY/Lexar/Transcend.

5) Would I be better off downgrading to a smaller card with a higher class? (i.e. 8GB Class 10?)

It depends!
I have been using a 16GB Transcend Class 6 card, for the past two years or so, and have had zero issues with it.
I also have a 16 GB SanDisk Class 2 card (although I don't use it in my Nexus One), and again, I have had zero issues with it.
I certainly would not put any faith in reviews on Amazon, etc. If anything, I would look at a reputable tech review site like tomshardware.com or anand-tech.com. Otherwise, buy and try, and if you are not happy, return it.
Wow! Major thanks for that reply! Was very helpful!
transcend class 6 is a great card. sandisk are also great.
+1 on the A-Data 16gb Class 6--great for a year now
Have read GOOD reviews on a Lexar 32gb Class 10
Probably my next card
Here is a nice chart showing speeds of various classes/cards

+1. Works great

I have a SanDisk 32GB Class 2 card that I've been using for about 6 months. It's performing almost as well as the SanDisk 32GB Class 4 card listed in the CyanogenMod SD Card performance wiki table. Using the same testing protocol, I'm getting 5.67MB/sec writes and 11.28MB/sec reads.
Wintec 16 gb class 10 from Fry's. It performs like a class 8.5, not bad!
I bought a 11 euro 8gb micro SD class 6 with A2E in CyanogenMod 7 and runs like a charm .
