Class of SD card - Venue Pro General

Did my Mango update fix the "class" issue for Micro sd cards. Can I use a class 10 card now?? Or is this a DVP issue?

The class is not a DVP specific issue. It's a MS WP7 OS level issue/limitation. Class 2/4 is the max recommended (not by MS, but by user experience).
Read here for details on the card class.

Has anyone ever tried a class 10 just to see if it would work? I only ask because i can buy a class 10 for only 10 dollars more than a class 4.

I would save the ten bucks and get something that's more widely accepted to work.
FWIW a Class 10 is only worthwhile if you're constantly dragging heaps of files (or big files) backwards and forwards onto/from it.
The Class signifies the sequential transfer speed. Manufacturers tweak the random access times to boost sequential throughput. Random access times are things like saving camera photos to the SD card, loading the gallery, loading the music collection, running Apps from SD etc.
You will sacrifice everyday 'zip' to gain good throughput for big file transfers. Class 10 cards, to me at least, are just not worth the trouble. I'd rather have good speed in everyday tasks than good speed doing a card dump back and forth. YMMV of course

I kinda knew what the differences was, but thank you for the refresher
I actually did buy a class 4 card here yesterday and it should be here tomorrow, or amazon says. But i was more asking to see if it had been done.
Thx

Lol, sorry mate. I may have misinterpreted your question a little!
Appreciate the 'thanks' though!

I'm using a class 10 card, no issues so far fixed all the problems that I had with the original one plus it's much faster

Has anyone tried a Class 6/10 MicroSDHC card?

Found some Transcend and A-Data class 6 MicroSDHC cards that are sold cheaply on Amazon, but I'm not sure I want to spend the extra cash if the Evo has bottlenecked write/read speeds. So I was wandering if any of you have tested out a class 6 or 10 MicroSDHC card on the Evo.
The Evo comes with a Class 2 card.
Download "SD Card Speed Tester" from android market to base our results. Will be posting mine in a bit.
First test results for 8GB Class 2 MicroSDHC Card(Comes with Evo):
Write speed is 2.0MB/s
Read speed is 9.0MB/s
Second test same card:
Write 4MB/s
Read 9MB/s
Well I read that this test is inaccurate. I will try to find better, external methods.
Does the Geebees matter when it comes write/read speeds on SDHC cards?
I bought a 32GB class 6 from ebay. took a few weeks to get since it came from hong kong and i paid 40 bucks :] anyways, writing to the sd seems smoother to me. i havent "truly" tested since im a complete n00b

Since there are no 32 gb class 6 cards... you got taken.
I bought a 16 g class 6 in amazon. How do i test it? I mean to me writes and reads fast but is there a appl for that?

without any "real" tests in android there really doesn't seem much of an improvement. mainly b/c the small amount of data that apps use.
nandroid back ups are faster though and prepping sd card at boot up is faster.
no numbers though.

shoot, didn't think of testing that.

i went to a 16 gig class 2 card since space was more important than speed for me.

Oh please do, can't test it, don't have a class 6 card. Hope some people who do stumble onto this thread.
I bought a 16GB Class 6 mSDHC card and I can tell you that it is noticeably better than the shipped 8GB Class2 card. I notice it most when playing back high bitrate vid, I ripped some stuff from blu-ray to 800x480 mpeg4 and it loads the video faster now and plays without a single hiccup. Also from time to time I would get hiccups in the 720p videos recording with the class2 and I have not had a single hiccup with my class 6 card.
These are just my observations I have no actual measurements to compare so take this with a grain of salt.

Sorry, confused myself with the standard SD.
I just ran that SD speed card test, transcend c6 card. Not using a2sd or anything else. It reports write speed at 5MB/s, read at 10MB/s. Says its a c4 card. Dont know how accurate the test is but thought itd be useful posting...
*edit* ran it a second time and got write at 5, read at 11. Seems pretty consistant

Test multiple times, for some reason I got 4MB/s write the second time.
ran test a 3rd/4th time.
Write 6MB/s
Read 10MB/s
Write 5MB/s
Read 11MB/s
A fluctuation of a meg up or down i think is normal. The program might also round seeing i saw no partial numbers. Now as far as if its worth it to get a c6 id say yes regardless just for the wearleveling features.
from cyaogen wiki: http://wiki.cyanogenmod.com/index.php/Swap_and_Compcache
However, newer, high-end SD cards feature wear leveling, a mechanism that distributes write wear uniformly over the entire memory card by dynamically remapping logical memory blocks to different physical memory blocks over time. This largely alleviates the issue of card wear when using applications that tend to write to the same memory blocks over and over (i.e. swap). Most Class 6 microSDHC cards include hardware wear leveling, while Class 4 and lower cards typically do not. This feature depends on the decision of your card's manufacturer. A-Data and Transcend Class 6 cards were specifically cited as having hardware wear leveling.

I have a 16GBA a-data class 6 in mine and the speed test is showing 8mb write and 12mb read. Not sure how accurate that is though, the read speed is about 4mb faster than what my computer told me it was.
A-data cards are fast but if you get another brand make sure other people are saying they can do what they say they can. There are a lot of companies who flat out lie.

Don't know if it's good or not but at least says is a class6
I seem to have gotten lucky with my Class 2 16GB.
Ran SD Card Speed Test from the market 3 times, and all 3 tests came back with at least 6MB/s write speed. Got it for $25 shipped off of Ebay. PM me if you want the seller, maybe someone else can get lucky too...

Make sure you test it thoroughly before you run out of time to file a claim. There have been a lot of 16gb cards with the 32gb markings coming from china. It's formatted so it looks like the space is there but they wont let you use more than 16gig
Actually alot of the cards on ebay at 2gb cards. Not even a full 8 or 16. Also if you want to do a better test for your sd card speads use ATTO. its free and gives alot better breakdown. It runs on your PC.

SD read/write speed causing lag on my HD2 but...

So I downloaded this app call H2testw.exe to test for legit sdcards but it also tells the read/write speed as well. I am testing my 8gb and 1gb cards. I set it to write a 300 mb files to the card and verify it.
Info about Android running on the two cards:
8gb = lags coming out of sleep, touch screen freezes, write~7.5 mb/s, read~12mb/s
1gb = no lags, no touch screen, write~4.3mb, read~13mb/s
I'm confused. The read speed is almost the same yet the 1gb microsd is more responsive running MDJ android compared to the 8gb microsd. Any thought?
UPDATE: Maybe this is what's causing the problem. Stolen from Engadget.
What we've learned from our tipsters and from documents culled from Microsoft, Samsung, and others is that the big issue is random access performance -- a figure that isn't taken into account in a card's class rating. Ironically, Microsoft discovered in its testing that cards with higher class ratings actually performed worse on Windows Phone 7 because the tweaks card manufacturers make to achieve high sequential throughput can actually hurt random access times. There's some rocket science involved here, but basically, it's a tradeoff and a bit of a gamble -- if a manufacturer tunes a card for a high class rating, it takes more time to access the first byte at a new location on the card because it's optimizing access for that area of memory, but once it does that, it can blast sequential bytes at very high speed. If you've got a lot of small reads or writes you need to make to different files at different locations in the card's memory, though, you really start to suffer. Cards with lower class ratings tend to spend less time optimizing sequential access prior to the first read / write operation, so it can move around the card (that is, access it randomly) much faster.

They are probably different classes, plus it naturally takes longer with a bigger card because there's more files and more space to read and write

I get screen freezes with 8gb and up but rarely with new builds, haven't tried a card higher than class 6
Also I'm on radio 2.15

Oddly enough, I have two 8gb cards, one class 4 the other class 6, and they hiccup more than my 16gb class 2.
Now that is weird.
I'm lost myself...I'm thinking off just getting me a 4gb card and hope for the best...
I heard the 16gb class 10 is perfect but it still cost to much for nand to be around the corner

16 gb class 10 no lag cost me over 100 pounds tho

Cheapest 16GB - lags from time to time :/
Maybe defragmentation may help?

Defrag wont help...scan for errors...try to have only the android folder and see if it makes a different ..
Btw, guys...
all sd cards are not created equal. all sd cards of the same CLASS are not created equal.
Check out the ongoing drama with win7 phones with SD slots....
class measures throughput, what affects the SOD and related issues is random access speed, not throughput so much.
It's just my 2 cents, but I've tested Class 2, 4, and 6 MicroSDHC cards and found very little noticeable difference once Android is fully booted up and running on the HD2. Moreover, none of the cards create screen freezes or SOD issues or high battery drain problems here. That said, I have noticed that the actual boot time and file transfer speed (from the PC to the card) can be faster on average with quality higher class rated cards of the same size. Also, I've found that the larger the card size, the longer the android boot time, no matter the class. Guess that makes sense, as the system need to read more sectors with larger size cards. Please note that I've only tested Sandisk, Toshiba, TopRam and Samsung cards to date. What's kind of strange is that the Class 2 16 & 32GB Sandisk cards run just as well or slightly better for some reason than some of my higher class rated cards. Go figure...
As far as issues go, I recommend only using quality brand name cards, no ebay fakes or cheap no name brands. Also, I've had great luck formatting all my cards with SD Formatter v2.0 and v3.0, using the quick format mode with the standard 32kb cluster size.
Best to all,

Great info here. I think I will just order me a new card from a reputable brand. Maybe my card is just getting old. Maybe a 16gb from Amazon will do. They aren't too expensive nowaday. ~$26.

No, not on the sd but radio does effect how the build will run, your phone calls, your battery.
Could this be the reason why class don't matter on hd2 android? I mean even some class 4 & 6 have lag and sod problem. I pulled this bit from engadget. It's an article on wp7 and memory card issues.

[Q] Performance tweaks?

Hi everyone,
could someone please explain me what all those "performance tweaks" are that the chefs are cooking into their roms?
i cant find anything about what they did... (search is offline for 20-30 min and other external searchengines also not find anything intressting)
i can see in some videos on youtube that the phone is faster - but why?
im using a class 6 16gb sdcard, so thats not be a problem i think...
can someone please enlighten me?
Thx!

ah somebody else noticed this, i believe they messed with some caches and that about somes it up, to be perfectly honest i dont see any where a noticable speed improvment could be made with regards to the UI so its all a bit of FUD if you ask me.
with regards to your speed, just because its a 16GB class 6 doesnt automatically make it work, infact, if its stable at all your on to a winner, ive got a class 2 thats quicker than a 4, its just luck of the draw, most slowdowns are SD related, try other cards, dont splash out because it might not even work but play around and see what you can get.
Most chiefs use these tweaks
Not really "performance", more "optimizations"

Yeah, it's not the rated class that matters with wp7... the class just rates the sequential write speed. It's random access speed that matters with wp7 (or when running any os off a sd card)... it's the time it takes to access small random bits of data when to os needs it. Higher class cards actually tend to have lower random access speed because of the tweaks the manufacturer does to raise the sequential write speed.
To raise the sequential read and write speed, the higher class card will initialize the part of the chip thats being used before actually using it so it can then write or read to that part more quickly... but that takes time to initialize, and ends up taking longer if you are just grabbing one little bit of data from one part and a bit from another part, etc than it will take a class 2 card which doesn't do the initializing process and just starts grabbing the data when it's asked to.
Microsoft found this when testing sd cards for wp7... class 2 cards tended to work better than class 6 or 10 cards. It doesn't necessarily mean a class 6 or 10 card won't work, or that a class 2 card will definitely work, but more class 2 cards worked than class 6.
Also, since card makers don't really rate the random access speed, they don't keep the speed very consistent batch to batch... even with a card that's the same brand and class. You might get a Class 4 sandisk that works great, but someone else gets the exact same class 4 sandisk, but it was made a week later at the same factory and it may not work. The chips they use can be different from batch to batch, and they only watch and keep the sequential read and write speeds consistent.
Hopefully now that wp7 needs cards with good random access speed, card makers will rate that speed and sell cards good for wp7. And also when running android off SD, I've found that random access speed is what makes the biggest difference in performance. I remember reading about people having more lag in sd android builds with higher class cards... well that's why.

Thanks for the good explanation from the hardware point of view. but again all tweaks they made are software side.
Could it be that this is just a subjective speed improvement?

[Q] SD Card Class Question

Ok.... So I have a 32gb Class 4 SD Card. When I went from the stock 16 class 6 card I noticed a speed difference... And well.. It has finally got to me... I am looking at going class 10 but I am wondering if anyone has done an upgrade like this and has any input.
I understand the class number is directly related to the speed in mbps but I guess what I am really curious about is will the epic write/read the card at faster speeds (than 6 [which is stock]) reducing my lag spikes in applications, pictures (taking and viewing), and in gallery 3d(While creating thumbnails [I have noticed this has slowed down the MOST])
For anyone who is interested I am looking at getting this SD card (Please note that I have nothing to do with this seller on amazon and am purely asking for opinions)...
amazon /Patriot-Signature-MicroSDHC-Memory-PSF32GMCSDHC10/dp/B004H8FTCU <----- Insert .com
Again I do know the pure fact that a class 10 offers more speed than class 6 and 4 but is the epic capable of using that speed?
Thanks in advance!
I don't know if our hardware will push the speeds of a class 10, that's not saying you cant use it, just saying you likely won't get those speeds out of it. Most of the time you can't get that much out of one even if the hardware will support it. I'd be willing to be 60% of cards out there are over classed or numbers are inflated from actual production chips.
"Stock card" was a Class 6? My launch day Epic came with a Class 2...

Yes. Our hardware can. I have done tests transferring files from my computer to the USB card via my phone and it is extremely fast. Camra speed has also dramatically increased if you are taking HD photos. Camcorder speed also increased. But I was going from a stock class 2 16gb that came with the phone to a class 10... So coming from a Class 6, I dunno how much of an increase that would be.

Tips to improve camera/camcorder performance.

I) Change the SD card.
-------------------------
Although Dell's stupid camcorder settings probably should not overload the class 4 card that comes with the phone for the most part, a 720p video I recorded using my Class 10 card has a bitrate of roughly 6MB/S, which is higher than the 4mb/s a class 4 card is supposed to be able to transfer. I changed to a 32GB Sandisk Mobile Ultra Class 10 and there is a noticeable difference in the smoothness of the video recorded. Some lag is still present(In reality the phone records at 23 fps as opposed to the 25fps Dell says it should), but for the most part the video is now acceptable. Maybe a placebo effect, but photos seem to be captured slightly faster.
II)Settings in the Camera.
------------------------------
This makes a HUGE difference in the viewfinder, where it's silky smooth one second and laggy as hell the next. Turn auto-banding on,change the scene mode to sports or something,and if you want change the white balance from automatic to something else.
More tips to be added as I discover them
Great tips! Especially your second point.
Thanks for the info!
Theres a lot of discrepancy as far as choosing the class of memory card for the dvp. Some users say stick with class 4 because its more likely to be accepted with the dvp, some say get class 6 or class 10 due to higher speed. However, is getting a higher class card riskier? I have read online that the phone may get bricked if you use an incompatible card and it is safer to use a class 4... is this true or is getting a class 10 card okay?
My personal experience is that there is no problem with a SANDISK card.(maybe other popular brands too, but Sandisk announced something about Windows phone compatibility, and the stock card is Sandisk too, so it's the best bet)Maybe if you use some cheap-ass no brand card then it won't get recognized, but I don't think you'd entrust your phone and all your valuable information on those. Seriously, get the class 10, it makes a lot of difference in performance and usability.
I got a Transcend working

Transcend isn't a "cheap-ass no brand card" but thanks for the info. The thanks button doesn't work for some reason...
