Help Micro SDHC card discussion for the Evo 3D.

[Cashprizes]

This will be my first smartphone, and I just wanted to ask some newb questions in anticipation of this phone launching ;p

Will it come with a micro sd card? I wouldnt think so since stats mention 4gb onboard storage. I saw some other posts with people being like "if it doesn't come with a card I will do so and so...."

Do these people have reason to believe it would come with a card? Have previous Sprint or HTC phones come with a card? I will still probably buy a 32gb card but would be a shame to have a pack in card that I wouldn't be using.

Also, seems like the best deal for a 32gb Micro sdhc is around $60 which is fine by me. But the ones I see listed for this price are class 2. If I put the card in the phone and never remove it do I really need a class 4 or 6, which from I read xfer data faster? I can't imgaine what other devices I would swap the card into, and device can stream data over a usb if I need to transfer a photo or somthing.

Also I read that Sandisk is the best brand if not equivalent to being as good as any other brand. Any opinions there are appreciated.

I was wondering the same thing.

since its got higher res recording and 3D recording, which may work better with higher read/write speeds, will that mean I should go for a higher "class" SD card (i.e. class 10 SD card)?

Will it come with a micro sd card? I wouldnt think so since stats mention 1gb onboard storage. I saw some other posts with people being like "if it doesn't come with a card I will do so and so...."

Yea, the 3vo will come with an SD card... 8GB. Most Sprint phones do... EVO 4G came with an 8GB SD card as well.

And the on board storage of the 3vo is 4GB (not 1).

Lexar and Patriot both make 32GB Class 10 uSDHC cards. Patriot in specific is big in the memory game and Lexar is good as well. I have a Patriot card in my 4G right now while I wait for the E3D. It works perfect. A few others on other forums have the Lexar one and says it works for them.

What does having a class 10 card improve? Load times for any thing saved to the card?

Load times to and from, read speeds as well.

Load times to and from, read speeds as well.

On many devices, some video recording qualities require a certain speed of card as well. (E.g. maybe you can't do HD recording without class 6 or better -- something like that.) I haven't seen any specific requirements for the EVO 3D yet, but we might find out more later.

I'm not sure a Class 10 card is necessary. I've always been under the impression that they are best used for professional photography.

 

[jerofld]

I've recorded on my DroidX's Class 4 SD card in HD with no problem. Also, 8GB will probably be more than sufficient of an SD card. Unless you plan on holding a lot of music/movies on it.

Also, when you get the phone, do yourself a favor and make sure all apps put themselves on the internal memory. Porting apps to SD card is more for the lower end/older phones that don't have a lot of internal space. The E3D is definitely not in this class. Putting apps on the SD card just causes problems. It makes widgets not work and if you connect your USB cable and have it in Mass Storage mode, the apps on the SD card will crash.

I ordered a Kingston 32gb class 10 card. Although Class 10 may not be necissary for the E3D, there are other things I can use it for.

Same here, I been looking at these class 10, but not sure if they will work in the phone.

Those will work but what are you trying to accomplish with a Class 10? You're using this on a phone. Not professional photography or the few other special cases.

What Speed Do You Need?

To help you find the right speed, SD/SDHC cards are broken down into four classes: Class 2, Class 4, Class 6 and Class 10. Class 2 cards offer a minimum sustained data rate of 2 megabytes per second (MBps), Class 4 of 4MBps and Class 6 of 6MBps and Class 10 of 10MBps. Depending on which manufacturer is selling the card, the speed class will either be prominently displayed or buried in the specs. Either way, look for it.
For standard definition camcorders, an SD/SDHC card with a Class 2 speed is all you would need. It

 

[autorail1]

Cause I cant find any Class 6 ones

which one is the EVO3d? Microsdhc host device or standard microSD enabled device/readers

Compatible - with microSDHC host devices; not compatible with standard microSD-enableddevice/readers

Those will work but what are you trying to accomplish with a Class 10? You're using this on a phone. Not professional photography or the few other special cases.



That was the best summarized version on about.com I could find in a quick google search. All you'll be doing is paying extra money for something you do not need.

I just bought this, much cheaper than some of the other ones linked.

FYI, I'm of general agreement that most people do not "need" the higher classes and could probably get away with a Class 4 (though we will have to see what bitrate the video is being encoded with), I will point out that for those of us that are impatient (like me), a Class 10 card would show its benefits in transferring media or video back and forth between your computer.

--in particular, the gigabytes of music and movies I swap in and out of my phone regularly.

 

[you2]

I think the issue is they want the "best" and not good enough. That's fine for folks who like to buy stuff knowing that next month it will have to be replaced to maintain the 'best'.

Btw for the transformer (asus) I find class 6 more than adequate for streaming videos. I guess it isn't the best; but it seems to be good enough (for me). Actually I was looking for class 4 but the vendor was sold out so I ended up with class 6 (rather have class 4 because I'm a low class sort of person).

However if you actually want the best be sure to examine benchmarks for both new and used objects (r/w times do change depdent on which technology they use to manage free space; esp as you delete objects). Not all class x cards are equivalent and in many cases class y (y < x) can be faster in the cases that might be most relevant to your usage.

 

[nkd]

if you are recording at 1080p it is recommended that you use class 10, class 6 will probably do as well. I wouldn't buy a class 4 these days, the price difference is very minimum.

 

[ovrrdrive]

Always buy the fastest card you can get. If for nothing else than shortening the load time when you're flipping through the gallery. I have about 700 pics on my phone and a fast card makes a big difference in the loading time...

 

[RedWingsFan]

I'll be using the 16gb Class 6 that is currently in my EVO 4G

 

[autorail1]

Any one know if the evo3d is Microsdhc host device or standard microSD enabled device/readers

 

[ogrenator]

its sdhc...anything over 4GB is sdhc..so yes everything has to be sdhc at this point...ill prolly use my 16 from the evo on the 3VO till I find a good deal..but 60 for a card isnt bad I just feel like it should be hitting like 30-40 for one in a month or two with how they have been dropping lately

Being a lowly teenager with no job (Best Buy won't call back, even though I'm more qualified than most of their sales reps), most, if not all, of my current income is coming from mowing lawns. I can get around 30-40 a week for now. As the summer progresses, I'll have a decent stockpile of money with which I intend on getting one of these SDHC cards. I'm going to get at least a 16GB, as the 8GB I have in my current Intercept isn't great for music. But if I'm really impatient, should I get a class 6, or just jump straight to 10?

Class 6. I guess I am in the small niche of users who does not use their phone as their main device for everything. If I want high quality pictures, I'll use my SLR. If I want high quality movies, I'll use my HD camcorder. I can't imagine transferring GB of data back and forth between my computer and phone. And even then, being in that big of a rush that I can't walk away for ten minutes and come back when it is finished.

Price difference between a Class 4/6 compared to a 10 is a little insane to be considering this for a phone.

As a teenager with more time than money, this is a wonderful opportunity for you to really exercise what it means to do a cost-benefit analysis.

I'd think about what the differences in SD classes really means in terms of speed, what benefits/limitations each speed means, and whether $$$ is worth whatever those additional benefits are.

You'll find that one of the big limitations that exists with respect to speed is video recording; the card needs to be able to write data as fast or faster than the video is being generated. Fortunately, this is easy to figure out -- because video has a characteristic called the "bitrate" or how much data a video takes up per second of time. Though we don't have the Evo 3D yet to know the precise bitrate it records at, I bet you could find some video samples from its sister, the Sensation and determine the bitrate of a 1080p video from it.

Then you'll know the minimum card class you need and can go from there in terms of figuring out cost/benefit.

You should also let us know what you find

I was just looking at this on Newegg. For a 16 GB micro-SDHC, most class 6 are $25-$30. Class 10 is typically $10 more -- i.e. $35-$40, but there are a couple for under $30, including a PNY branded one.

(I agree it's not necessary to go with a class 10, I'm just noting that the price difference doesn't seem as bad as I'd expected.)

Sadly, I'm wondering if there's any chance it takes micro-SDXC cards for whenever those become available. 32GB is almost a little small if I wanted it to house my music collection and a few movies.....
