Micro SD card - G Tablet General

I've been looking to buy a 16gb micro sd card, there are a few different class types. Is there a noticable speed difference and performace between the 2, 4 or 6?
Thanks!
Ed

you will see a performance difference in write speed - copying files to the SD card - getting your movies and music loaded; but not with read or playback.
Class 6 is required by cameras doing video - but for playback class 2 works fine. I don't think it is worth the money to go Class 6 if you don't need it. Also, don't buy the deals on eBay - most are cheap knockoffs that fail after some time if they ever work right.

Thanks. This is something I've been curious about for a while.

MicroSD for Froyo - general consensus?

Hello,
Now that Froyo more or less came out and apps will start having Apps2SD function, it's time for a MicroSD upgrade.
What I want is on-phone performance - that running heavy 3D games on SD would perform as smoothly as if it was on internal memory. Is there a general consensus on what brand/class would suffice, and what is overkill? I have no concern over data cable transfer speed, as I'm pretty sure the phone will limit the speed much before the SD card does.
I'm looking at this Sandisk 16gb MicroSDHC Class 2 for $35 after shipping:
http://www.amazon.com/SanDisk-Flash...ref=sr_1_1?ie=UTF8&s=pc&qid=1275145563&sr=1-1
Anyone know if this would suffice?
Past threads have always went on tangents about good brand vs knock offs, how class is important vs. a marketing ploy, etc etc. Has a general consensus been reached in the xda community over what is sufficient but not overkill for onboard performance? Perhaps people who have already ran App2SD and use games and videos a lot have some input.
Thanks
I have a Top Ram 16 Gig class 6 and I think I paid about the same as you looking to pay for a class2. I also have a class2 that I have had for over a year. I used to use it in my blackberry. It still works and it is made by one of the cheap manufacturers.
Argh, I'm suffering from chronic SD corruption. So I'm in the market for a new chip. Think I'll spring for a 32gb this time. What's the latest on one that's both compatible and fast? And cheap too, that would be nice, links appreciated.
Considering that due to the amount of RAM the N1 has your main apps will be loaded already so card speed is not a significant factor, unless you use lots of different apps on a regular basis.
A faster card is beneficial mostly for the time i takes when I am loading up new music and possibly vids if you use it for that
This is the first 32gb MicroSD card I have seen "In Stock" Pretty expensive for a class 2 though.

Im not sure the nexus 1 can handle a 32GB card , wow that's a lot lol, but you can get one for like $30 on ebay... http://bit.ly/9J7u2S
You can get a 16gb class 10 for about $90.00.

Micro SDHC is a standard that supports up to 32gb. Of course it can handle it just fine.
I run a 16gb Class 6 in mine, works fine
bewar ebay, there a lot of folks selling fake cards. They even read as what they were sold as but then fill up mighty quick............
The class is not needed I don't think
I have a class six and have been running games on it from sd for 3 months cant tell a bit of difference. I run linpack from sd and it works fine too!
the only real 32gb card is found here., http://www.sandisk.com/products/mobile-memory-products/sandisk-microsdhc

I'm running a 32gb Sandisk Class 2 in my Nexus as of last Friday. No problems (apart from a looooong time to refresh the media library after resyncing my music).
You can not get a genuine 32GB Micro SD card for US$40.
A good class 2 card (2MB/s) will offer you the same performance as any other class in your phone.
The limitation is not the speed of the card.
Buy a brand name card with the capacity you require and be done with the complexity.

I don't know too much about transfer rates but basically what you're saying is that a a brand name class 2 card will be just as good as say a class 6? I'm in the market for a new SD card as well, and the class 6 cards are much more expensive. I'm wondering if they're worth it.

No, in a phone they're not worth it at all and people who say so are either selling snake oil or are embarrassed because they've paid for one and are foolish for doing so.
The best I can do just at the moment is this:
wikipedia said:
In applications that require sustained write throughput, such as video recording, the device may not perform satisfactorily if the SD card's class rating falls below a particular speed. For example, a camcorder that is designed to record to class 6 media may suffer dropouts or corrupted video on slower media.

The Nexus, like probably every other phone out there, is a) not typically used for high rate sustained write activities and b) is designed to write to class 2 media to begin with.
If you have a large, highly fragmented sd card higher speeds will help. This of course is easy to avoid in the first place.
Get a higher capacity, class 2, brand name card for the same money and you're away laughing.
NB - If somebody waves a magic wand and all of a sudden the Nexus can record video at 1080p at a high enough bitrate then perhaps my advice would be invalidated... but don't hold your breath for that to happen...

Thanks for the info man! I was obviously misinformed, you just saved me a bunch of money
so just curious. now that CM 5.0.8 comes with 720p recording, would a class 2 still suffice?
I am also searching the web recently to look for a cost-effective high vol microSD. My finding is: don't 100% trust the "class" specified by mfr. I used ATTO Disk Benchmark to test two 8G microSD that I have: Transcend 8G Class 6 and Sandisk 8G Class 4.
<Transcend Class6> Write: 6-10MB/s Read: 16MB/s
<Sandisk Class 4> Write: 14MB/s Read: 20MB/s
From similar test results on the web, it seems that Sandisk uses to under-state the performance of their card. Finally I get a Sandisk 16G Class 2 for my N1, and here is the test result with the same setting:
<Sandisk 16G Class2> Write: 7MB/s Read: 20MB/s
Although Sandisk only specifies it as class 2, it actually performs like a class 6.
I suspect the importance of the speed of the SD card too, coz I think the write speed into ROM, should be way slower than 6-7MB/s (correct me if I am wrong ^_^)... If the speed of v2.1 w/o app2sd is acceptable to you, then v2.2 with 6-7M write speed card should be logically fine with you.

huh that's interesting. i just might pick that up from amazon then..
I Dont think fragmentation makes any difference to write speed, these are not mechanical devices like hard disks.
Also defragging is pointless and shortens the life of the card by increasing the number of writes.

Upgrading microsd card

I want to upgrade the stock 4 GB microsd in my unrooted htc desire to a 16 GB microsd card. My question is can I copy what is on the 4 GB microsd and transfer them to the new 16 GB microsd and just insert it in? would all programs work?
many thanks for your help.
Yet, the apps are on the phones memory and the info is on the SD card so you can just copy across.

I agree - I had lots of problems with an unbranded 16GB card. Eventually ebay closed the seller down as there were so many complaints. I did get my money back via paypal. I finally bought a branded 32GB card - costly (EUR100!), but I love having so much space for my music / video.
Is there really a need for anything above class 4?
My HTC Desire came with a sandisc 4GB class 2. I want to get a larger card, but never had any reading issues with the class 2, and music and video played off it with ease.
I've seen the following item here, which is for a class 6.
http://www.amazon.co.uk/Transcend-m...r-TS16GUSDHC6/dp/B001PLIG5Y/ref=cm_cr_pr_pb_t
Anyone got one of these?
I've just bought the 'ultra' version of Sandisk's 16GB microsd card and I am very impressed with it so far.
Personally, I always feel that it is best to stick with the tried and trusted brands, and sandisk products have always been excellent for me
I just bought a 16GB SanDisk class 2 from amazon and it writes on average at 5MB ish
-------------------------------------
Sent from my HTC Desire
I thought the class number i.e. 2 meant the read and write speed 2Mbps. Therefore class 6 would be 6Mbps. If you have a class 2 and get 5Mbps then that is pretty impressive.
The Class of the SD card is simply the *minimum* sustained write speed on a card which is completely unfragmented. So, a completely blank Class 2 card should always be able to write large files out at least 2mb/s, but can easily be faster.
My 16gb Sandisk Class 2 reads at 20mb/s and writes at 7.5mb/s - well above the Class 6 minimums.
Regards,
Dave
my 32gb is a class 2 and i have zero issues with streaming video or music from the card, i expect when i root that apps will not be an issue either. plenty of read write speed.
the higher classes are for devices that require a higher bitrate for recording such as mini hd recorders and such.
Im running a SanDisk 16GB Class 6 and its like Lightning!

microSDHC 16GB?

Will i need higher than class 2 microsd card to support HD recording on the DHD something like ultra high speed class 6 microsd card for better access speed?
Though im not sure if class 6 is supported on the DHD. if anyone can shed a light on this is greatly appriciated.
As they provide a Class2 card with the phone and advertise 720p video recording, the Class2 standard is apparently enough. This is just a guess, but I strongly think that DHD supports Class6.
Ok, just not too sure if class 6 is based on ver 2.0

It's enough cause we are talking here of a phone that has plenty internal memory to buffer data when you are recording stuff in 720p!!! Class 6 or 10 are needed on digital cameras or digital video cameras cause they usually don't have such huge internal memory to buffer data while recording...
Basically we are talking DHD as almost a computer in these particularly case
something else to consider is transferring anything to your phone or back again to a pc or mac. A class 2 card will be much slower than a class 6 or even a class 10.
I just thought I would check what Class my N97s Micro SD card was and it is a class 6 8GB, so that should keep me going for a bit.
Its pretty rubbish that when people are pay £500 for a phone, that they ship it with pretty old technology micro SD card.

please post what micro sd card you are using and how you are finding it on the DHD, just so we can see which works the best.
the reason i ask is because I am thinking about getting a bigger micro sd, but not sure what to go for!

Its rated as a Class 4 card but I have actually obtained steady transfer rates of 6.5 MB/s and even at times up to 10 MB/s with it whilst copying across large files from my PC to the phone via USB.
I really should look a bit closer before posting!

[Q] MicroSD Card

Been looking around for which microsd card to replace my venue pro one with. definitely want a 32gb one. Pulled up a few, are a lot of people having problems with the class 4 cards? Should I stick with a class 2, even though the 4 is about the same price, or cheaper? Here are the few I found, all around $80. Price doesn't matter, just want the one that will work the best.

I'm 100% sure someone had posted the 32GB MicroSD card S/N they use. I don't remember which post it was, it is somewhere in the Venue Pro General form.
I think class 6 should work. Max Miller at ZDNet has posted a blog about how he swapped a troublesome dvp's 8gb card with 32gb n the dvp is working like a charm after that. It has a video aswell.

Whats the largest SD card Windows mobile 7 can handle, and if it's less than 128 will it be able to recognize "partitioned" SD cards?
I use a sandisk 32g class 2 and it works fine. Did find a lot of class 4 of same price but skipped as I only saw that class 2 works from posts online.
And from a random (not sure if reliable though) article online, it says WP7's file system depends on random I/O seek time (or alike) which is a different dimension from class, which gauge the continuous transfer speed.

Why would a slower class work better than a faster class of SD? Class ten is the fastest your able to buy.
If I can buy a class 10 32gb would it work?
http://www.newegg.ca/Product/Produc...61411-L06D&AID=10657534&PID=749547&SID=forums
I swapped my 8GB class 4 that came with the device to a 32 GB SanDisk class 4. I do notice slower write speeds - 720p video in particular seems to have a lag when capturing. Other than that, the phone is zippy fast.
I bought a Dell Venue Pro (normally hate Dell and don't give them the time of day) and from what i've been reading i'm going to be stuck with a class 2 or 4 (32gb) MicroSD card. And to narrow it down even further supposedly the ones that work best with these phones are sandisk.
So my questions are this. Will I actually be able to use a class 10 microsd card or is it a limitation of the physical phone. I mean windows is capable of 32gb and probably more.
If it isn't able to use class 10 right now will there be a firmware update for the phone that will allow it.
What would happen if i bought a kingston or patriot over sandisk (as i've always considered them the bottom of the pile)
I've been using a 32gb sandisk (class 2) for a couple days now and it's awesome. Despite being class 2, it's way faster than the crappy class 4 that came with the phone.
Random r/w speed is the most important thing to worry about with WP7 devices. Class rating does not say anything at all about random r/w speed, just about the maximum throughput. In fact, there is often a NEGATIVE correlation between class rating and random r/w speed - the higher the class, the lower random r/w.
So that's why class 2, 4, or 6 cards seem to be the best.
so could anyone give me a link of the best 32 gb sd card I can use for my DVP that would be awesome.
the one that came with my phone is starting to fail (constantly getting the black screen with memory card problem and asking me to change cards and reset)
another question
let's say something happens with my phone and I need to send it back for warranty repair, could I possibly switch out the sd card back to the original one, reset and be ok?
So does this phone have a SD card that is expandable? I just got the phone a week ago and thought it was built in and couldn't be changed.

No problem
I had a look at the Lexar, I've never used any Lexar products before, so I simply compared the reviews on both. According to the reviewers the Patriot is faster, and I've used Patriot's before and found them to have good speeds.
I guess you're gonna have to work out which is the cheapest and if it's fast enough for your needs. Personally I'd go for the Patriot, but I suggest you google both for reviews as it's you that's going to be using it.
If it doesn't have to be 32GB then this is worth a look..

That said, I have started re-ripping all my CDs (yes I actually pay for my music) to FLAC formats. With memory prices going down, the time is ripe to convert to loseless goodness.

Overkill much? 6 months ago I would have said pretty much the same, but once I got the SGS and voodoo sound FLAC made complete sense. You will notice the difference between mp3 and FLAC with a decent set of headphones. One example, "Broken" by Nine Inch Nails, I never bothered listening to this on previous phones or mp3 players, it sounded terrible because it's a loud, distorted, in your face album, but having re-ripped it to FLAC for my SGS I'm actually able to enjoy it again while I'm out and about, I also listen to a lot of electronic stuff, most of Ultimae.com's catalog for example, and the difference is quite noticeable, to me at least.
Number 1 use for my phone is as a music player these days thanks to supercurio and FLAC.
And yeah, I pay for my music too, I'm dreading having to re-rip over 600 CD's and pay for another HDD to hold 'em all on.
Just so you know
On the samsung i9000, there is no difference in performance between 32gb Class2 & Class10

That's not entirely true, there is a difference, but whether or not you'll notice it just depends on what you're using the card for. If you're camera is set up to record HD video to your external SD then it must have a write speed of 6MB or you will end up with choppy, stuttering crap quality video. If you're just using the external SD for mp3's or playing movies you've transferred from your pc, class 2 is fine, but it will take you longer to transfer stuff from your pc to your phone

the kingston 32gb class 10 are not fakes, they were release just after the sandisk 32gb class 2, when they were first released, but were taken off the market and discontinued, due to high price, i saw them and was gonna get one when the price drop (the shop i saw them are a authorised dealer, so you dont need to think the shop is selling fakes).
it was about USD 170, when you compare them to the class 4 version at USD 55, why are they expensive, well they are the fasted microsd to present, with write at 16mb/s and read at 22mb/s.
I also have 2 lexar 32gb at class 10, and the speed is nowhere near the kingston.
lexar write speed at 11mb/s
read speed at 17mb/s
if you still want to try out the speed, you can still get the 4gb, 8gb and 16gb at class 10, just to give you the approximate price, the 16gb will set you about USD 81, more expensive than a 32gb micro sd.

I stand corrected
I tried a Playstation emulator app, and I am pretty sure that I could get more games working after I got my class 10 16gb card.
Since I use my phone for emulators, browsing, music, media player, remote desktop and probably as a travel computer soon... then having a faster SD card really comes in handy. If nothing else, then it comes in handy when deleting 8+ gb from it, just to put another 8gb+ onto it. Having a few extra mb/s really matters when doing that now and then.
Is the built in SD actually class 10? I really hope so, but if not I should probably consider moving a few more apps to the SD.
the built in memory is a nand memory chip soldered on the main board, it's reads and writes faster than microsd.
I've been wanting to upgrade my external card (8gb I think) to a 16 or 32. I've only just recently become aware of the different 'classes' and speeds of cards... just how much difference is there (in usability terms, gallery, music etc) between say a class 4 and 6 (or 8 or 10) or whatever the different classes are.
Raw numbers won't really help me (as I have no point of reference lol) but are they REALLY much faster in normal use? Are they worth it?

To be honest unless you have your camera set up to record to the external SD I don't think you need to worry too much about the class of your card, 720p recording needs a write speed of 6Mbps, but as the prices have come down a lot it makes sense the get the biggest card you can justify price wise. One advantage of a higher class card is that it's quicker to transfer files from your PC to your phone.
If you want a 16GB class 10 here's a decently priced one

If you want a fast 32GB class 4 this is one of the best prices I've found so far

(I have a SanDisk 8GB class 4 and it writes at just over 7Mbps, Sandisk are know for under rating their cards)
If you just want a 32GB, here's a class 2, (SanDisk so probably faster than rated)

I bought a class 10 sd to replace my previous class 6.
I didn't notice a change! Speed was the same as on class 6.
Buy a class 6 sdcard instead of class 10. They are cheaper too
I think many people still dont understand the meaning of the classes that is stated on the memory card.
the class is just an indication of the minimun read speed and write speed that the card can offer.
so a class 2, 4 or 6 can reach the speed of a class 10 or even a class 16,
class 2 minimum 2mb/s
class 4 minimum 4mb/s
class 6 minimum 6mb/s
class 10 minimum 10mb/s
class 16 minimum 16mb/s
as for people who think there really is'nt any differences when compared class 2, 4 with a class 10, this will depend on what you use it for.
if your phone supports HD photo and recordings, then you will need a fast card, you will notice the speed differences, especially during recording videos, but for mp3's and phone normal use, then it does'nt show any differences.
