When buying microsd does class matter much? - Vibrant Accessories

I know speeds are:
Class 4 - Minimum of 4 MB/s performance.
Class 6 - Minimum of 6 MB/s performance.
Class 10 - Minimum of 10 MB/s performance.
Can the Galaxy S even get up to class 10 if I go that route?

Yes, it matters a buttload.
Yes the Vibrant can make full use of the fastest chips out there.
Spend a few dollars more at Newegg and get a good chip from a known maker (Crucial, PNY, Micron, etc). The stuff is pretty cheap anyways....worth a few bucks just for piece of mind.

I'd suggest staying clear of Kingston and *possibly* Patriot.
I've nver seen Kingston stuff work as advertised and Patriot is a hit or miss at best.

Agree with n2ishun
I agree withn2ishun
Crucial and the other he mentioned are way more ereliable and have a better burst capacity (ability to write for shot periods of time faster than normal benchmark).
SD Memory Card basic breakout these are just averages i have in my phone a 16 gig card that claims 20+mb transfer rate never checked it but it is fast
Speed Class -2 Normal Bus I/F SD, miniSD, microSD
micro SDXC data rate less than 3 mb per sec
Speed Class - 4 6 HD ~ Full HD video recording above less than 7 mb per sec
Speed Class - 10 High Speed Bus I/F Full HD video recording 10 Greater than 10 mb per sec
UHS Speed Class 1 UHS-I Bus I/F HD TV Real time recording (only available on bigger cards)

I dont know much about phone memory. i'll be getting my first smart phone this week (vibrant). I followed the link and the only company you had listed that i saw was PNY and they only sold cards at class 4 speeds. So besides kingston and patriot are the other's ok? Centon had a few class 6 cards that i was looking at. Or perhaps i should be asking are there any other companies i should stay away from?
thanks in advance

A lot of brands are okay. Well, that is if you buy it from a legit retailer and not from ebay where there is a chance for you to get a fake one.
Sandisk, PNY, Kingston, Adata, Transcend (I have a class 6 one), Crucial, and etc. They are all about the same. Go to Newegg for reviews.

Ah ok.
thanks alot.
Rodrigo

dont forget about meritline.com.
i get all my sd cards from there.

It only matters if you're impatient.

I wouldn't say "impatient" but sometimes we have better things to do than sit there and wait for a file to finish transferring. Especially big files.

Usually files don't really get big enough on phones for 4mbs to be a huge problem.
But I'm not going to argue with you, the faster the better definitely. The good thing is there usually isn't a big difference in price between the different classes if you're shopping in the right places either.

the stock card is a class 4. I have an 8GB class 6 from my G1 days when we were doing 3 partitions on one card (crazy to me now). Does it matter? Yeah... Is it worth spending a lot of money on? Matter of opinion... how much are you using the sd card for read/write? I use the internal memory most.

I can see speed being an issue if you're taking a lot of pictures and video and saving to SD card. I usually use my external just for music, so Class 2 is fine for that (still, wouldn't turn down a Class 6 card if the cost differential were slight).

What MicroSD are you using?

Hi, I have been searching on the forum in search of some information on MicroSD cards and came to no avail.
With my HD, it came with a 8GB Class 6 MicroSDHC. I think it needed it to play videos. I can't imagine using it with a slower card.
Now, my TP2 will arrive Monday and I would like to know the following:
1. Brand
2. Size
3. Speed (class)
4. Price
Is it performing well with the video playbacks or have you installed the SD Tuner software available for the HD?
What do you recommend?
Many, many thanks for any replies, comments and help!
Bought a A-Data microSD class 6, 4 GB at a local computer store.
Not the one i was looking for, i wanted the 8GB or 16GB but both where not in stock and the 4GB was less then 10 euros. I will buy a larger one in a few months.
With class 6 my phone isn't slowed down. A few years ago i bought a 2GB mini-SD, but my HTC Vox was slowed down very much. Didn't look to the class/or speed back then.
MicroSD cards based on SLC might be beter them MLC. IMHO i would always take a class 6 or higher card. However class 8 cards are hard to find.
I'm using the 8GB Class 4 card that came with my daughter's Nokia 5800 and it seems fine. Just watched an xdiv episode of Only Fools and Horses on it with no stutter or dropped frames.
I bought a class 6 off Ebay and it should be here on Monday so I can compare then
i'm using sandisk 8g class 2. whatched movies and played music, everything is fine. It only cost me just under tenner.
The performance diference between a class 2 or a class 6 is not that noticeable. However, at the price the cards are, I think it worths always to buy a class 6 card.
I bought a Transcend 8GB class 6 card. It cost me aprox. 20€.
The biggest differences I noticed between a class 2 and 6 card are:
-Taking photos is faster with class 6
-Browsing photos in sdcard is a bit faster also
-Viewing movies sometimes is a bit more smooth.
HastaSSSS
I have a 16GB class 2 Sandisk. I watch movies just fine. I figure with a class 6 i might be able to watch HD videos more smoothly.
Hi guys,
Thanks for all your replies. So from what you guys are telling me, it is always better to pay that little extra for the class 6 MicroSDs. But then again, is it worth investing in a 16GB Class 4 (no Class 6 available except the brand A-Data) or an 8GB Class 6.
16GB is nearly 4 times more expensive than the 8GB and yet it is slower. Shall I just get 2 8GB and hot swap the 2 cards as need be?
I bought a class 6 off Ebay and it should be here on Monday so I can compare then

I have read about this brand, and what others said was that their Class 6 under performs Sandisk's Class 4 Cards. Do yo notice any differences? How is the performance?
Also, I wouldn't recommend buying these cards off eBay. There are so many, fake cards on there. I know so, because I know mates that sell these cards. I would just buy from a genuine local store and pay a little bit more unless you don't care about performance.
Anyway, my last question.
What brand do you think has the best performance. Yeah, we can find out all the data about these cards on the web but it's nothing like the hands on tests from real users. So, will it be Sandisk, Transend, Toshiba, Kingston or the later A-Data?
Found a pretty review on the Sandisk 16GB C4 MicroSDHC cards. They compared it to the Kingston 8GB C4 MicroSDHC card.
Sandisk seems to be the company that is producing the fastest cards. It out performs Kingston.
But $133, is a bit steep. I think if I am correct a Sandisk 8GB C6 MicroSDHC is only $49.
What do you think?
You won't notice much difference between class 2 and class 6 as the device can only read at a certain speed, which is nearer class 4.
There are some cheap class 2 16gb cards out there, I have them and you only really notice if you install something like sdtuneup, but then again, you wouldn't notice much difference between class4 and class6
SanDisk microSDHC 16 GB Mobile Ultra works fine!
With the enclosed reader it is really fast via USB.

Cheers for the heads up about the TP2's read speed.
I was going to go for a 16GB class 2 but now might hold out for a class 4.
Haven't noticed any speed difference between my 8GB class 4 and 6 cards except that it's possibly slower than my Trinity but that may be due to the crummy TP2 stock ROM...

Please don't get two 8GB's, you will ruin the back cover of the device swapping the cards over all the time
My understanding is that the Class affects write speed, not read speed, so you won't see a difference playing movies on one or the other. You will see a difference in the amount of time it takes to get the movie onto the card (providing you aren't using ActiveSync, which will slow things down way beyond Class2 speeds).
I have a SanDisk Class 2 16 GB card on my Vogue and watch movies just fine with CorePlayer. Maybe a brief stutter once every 5 minutes or so, which I attribute to WinMo doing some other task in the background, not the read speed of the card.
In short, if it doesn't matter to you how long it takes to transfer large files onto the card, go with the least expensive.

Really? How much slower?
Yeah, I think I will go for 16GB for sure. The only thing now is what class. I am hearing 2 things here. I am worried about stutters on watching movies.
Some are saying speed only matters to write and not read.
But then I have read that it does matter, that is why there is a SDTuneUp for the HD.
I really don't want to buy a cheaper Class 2 card and only finding it is not working to my standards. I am pretty fussy about these things.
Any of you needed to install the SDTuneUp registry edit for the TP2? Do we need it? Anyone did any tests?

Check this out.
And this.
Class rating only refers to write speed, even though on the official SD association page it says "transfer speed." What they don't say is that it's transfer speed only one direction.

Hello ajbopp,
Thanks for your additional information. I think not a lot of people actually realise this. I always thought the Class Rating was how you determine transfer speed and not just write speed.
But there must be some ratings for Reading. Some cards are faster than others and that will certainly affect the rate of requiring information from the card, right? Because files are written in blocks and are distributed everywhere (fragmentation), so if the card is faster, then finding the blocks will be quicker, hence a better performance for reading movie files.
Just thinking logically how computer hard disk works. Not sure if that applies to SDHC cards. I also think the speed is also determined by the drive (the hardware reading/writing on the card).
There aren't many information on this. I have been searching around and most information I found was given by the companies that made these cards. Real tests are few and far between. Most websites I visited, tells me only of the write speed as I think that is what is most important to people who uses these cards, such as Photo Fanatics who needs speed for taking high end photos very quickly and for taking HD videos at 30fps. There is less need to know about read speed.
It's so confusing...
Got it yesterday. Thanks for all your help guys!
I finally went for the Transcend 8GB Class 6 Micro SDHC. Cost of only $187 HKD, roughly $23 USD. Didn't end up getting the 16GB as they didn't have any in stock and it costs 3 times the amount.
Without any tests, I just loaded my movies and it played very well. No dropped frames. No tweaks whatsoever.
Hello!
I had a TP with a Micro SD 8GB Class 2 card.
I'm considering buying a new one (lack of space available) and I wonder if I should consider a class 4 or 6...
I use the MicroSD to store software, pictures (camera), music (to listen), and some videos (to watch).
I don't intend to remove the microsd from the TP2 slot (have to remove the cover) so what I usually do is to connect via USB cable (data instead of AS).
So, transfering data like this will I notice difference with Class 2, 4 or 6?
I'd get a good price with this:
http://www.amazon.com/Kingston-Technology-SDC2-16GB-microSDHC/dp/B001RPD06I
is it good enough or should I buy a Sandisk or perhaps a Class 4 or 6?
Thanks
SanDisk and Kingston are both good manufactures.
Class 4 is faster than class 2 and class 6 is faster than class 4.
But on the other hand: class 4 cards need more power consumption than class 2 cards and class 6 cards need power consumption than class 4.
For this reason I bought 1 x 16gb class 4. That is the compromise of speed and power.

Again, this is only for write speed. I think it's an important distinction to make, especially if you are hoping for better video playback because of a faster card. The class of the card is not likely to have any impact on the device's performance, either video or anything else (other than file saving/writing operations).
so... for my kinda use there is no need for a class 6 right?
do you think a class 2 kingston MicroSD 16GB can be used for what I want?
playback music and some video... storage ... navigation?

[Q] Class 2? Class 10?

So I'm looking for SD cards for my vibrant. I'm wondering if I should be shelling out 100$ for a 16 GB Class 10 card or get the class 2 32 GB for the same price. Does anyone know if the phone might somehow be limited to certain file transfer speeds when connected via USB? I do intend to use the card for video and have all my apps on it. Thoughts?
From wikipedia:
The following are the ratings of some currently available cards:
Class 2: 16 Mbit/s (2 MB/s)
Class 4: 32 Mbit/s (4 MB/s)
Class 6: 48 Mbit/s (6 MB/s)
Class 10: 80 Mbit/s (10 MB/s)
Click to expand...
Click to collapse
You might compromise and look for a class 6 -- i've seen a lot more class 6's than 10's so you might get a much better value from a class 6 purchase -- unless you need/want the fastest possible.
Lets just say I survived for a couple of years or whatever the time frame was running my apps off my G1 on a Class 6 card just fine.
Avatar runs fine on my SD card so I'd guess at least whatever that is if you are running video.
Thanks for the input, anyone actually have a 10 that they are using? A 6 is a viable option...
Sent from my Vibrant using XDA App
Class 4 is plenty fast. Class 10 imo for this phone is a waste of money. I got a class 4 16GB for $32.99 last weekend.
Go for a class 6, 10 is overkill and really intended for mass writes in the form of very high quality video or photos in quick succession.

i have a 32 gb class2 and it plays my 720p .mkv videos just fine
Not all micro SD cards are made the same even if they say they are a given class. Stay away from eBay there are cases where people modify the firmware of the card and you get a card that is actually smaller or slower.
The best cards are name brands like Sandisk or Lexar. Transcend is also a very good brand and the tend to mark their card such that they always meet the spec but often read at higher speeds. Kingston is the name brand card that I have seen so far, but reviews on Newegg indicate that it's R/W performance isn't class 10 (<10MB/s). Some vendors interpret the class spec such that they say cards are class X if their peak read speed is X instead of their lowest R/W speed should not go below X.
I'd recommend getting a class 6 Transcend card (lifetime warranty). The sweet spot right now is 8GB class 6 for ~$20. Their 16GB is like ~$75 on Amazon.
Class 6 is good if you plan to run apps or put extended partitions / swap on it. That is what I did with my old G1. It is also a safe bet if your planning to record at 720p.
If you just need space for playing movies and music you can go for the cheaper 32GB cards. I'd pick a class 4 to be safe if your doing HD movies.

[Q] looking for new memory for galaxy s

hi, i posted not long ago about memory i bought from ebay..it was fake, i did return it and today i was given a refund from ebay........what i want to know is this
where should i buy my memory from...is play.com safe??? is amazon.co.uk safe??
im looking at some on play.com right now but daren't purchase till i know it won't be fake, also does play.com accept paypal?
what size should i be looking for??
what class should i be going for??
thanks in advance
order off of newegg if your looking for micro sd cards because they're cheaper for like 16gbs
If you store a ton (and I mean a TON) of music and possibly video on the phone, get 16GB.
If you do not meet that criteria, you are more than fine to grab a 4GB or 8GB and just get something class 6 or higher for speed.
Class 10 is overkill, but it is also a bit more future proof.
I personally have a 4GB class 10 and I haven't even made a dent in it.
Picked it up at Amazon for $14 or $16 shipped a few weeks before xmas.
Just make sure that it is Amazon or an Amazon authorized reseller and you're fine.
If you find a deal on NewEgg that includes free shipping, they also are outstanding to buy tech items from, as stated above.
Good luck.
Oh. One last thing.
Even if you think you take a lot of pictures, keep in mind that 1GB of memory holds approx. 1,000 pics taken at 5MP. Do you really plan on storing 16,000 photos on your phone?
Hi, I can't find it anymore but I've read somewhere that comparatively a class 2 or 4 performed better than a class 6 or 10. On a side note, if like me, you also watch shows or movies on your phone, take a 16 Gabriel Kingston class 4: they're cheap and perform very well! I got 2*8gb SD cards and 1*16gb and I'm very happy with them.

I think what you're referring to is the card-to-phone transfer speed, which I believe is internally capped, so even if you had a futuristic class 50 card, it still would not matter because of the cap, you're going to end up with 2-4MBs max speed. This means that in terms of use in your phone, you're fine with Class 2 and probably maxed with Class 4.
The DIFFERENCE is that if you take the card out of the phone and throw it into a reader, my card is going to transfer the data 5 times faster between the reader and my computer than that class 2.
It also can be used with an adapter and be thrown into a camera that takes advantage of high speed memory. It's the difference between firing off 24 pics per minute vs. 100+ pics per minute.
Here is the wiki link and a quick excerpt, the first number is the read speed, the next number is the write speed and that relates to how the card is numerically rated:
http://en.wikipedia.org/wiki/Secure_Digital#Speed_Class_Rating
Speed Class Rating
The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. It is equal to 8 Mbit/s, and it measures the minimum write speeds based on "the best fragmented state where no memory unit is occupied":[10]
The following are the ratings of some currently available cards:
* Class 2: 16 Mbit/s (2 MB/s)
* Class 4: 32 Mbit/s (4 MB/s)
* Class 6: 48 Mbit/s (6 MB/s)
* Class 10: 80 Mbit/s (10 MB/s)
Even though the class ratings are defined by a governing body, like × speed ratings, class speed ratings are quoted by the manufacturers but unverified by any independent evaluation process. 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.
Important differences between the Speed Class and the traditional CD-ROM drive speed measurement ("×" speed ratings) are that speed class:
1. may be queried by the host device
2. defines the minimum transfer speed.

1. Who said anything about eBay?
2. Samsung sends a warm and hearty "Thank You". It is customers like you that choose to pay a 400% premium for "name brand" when often times with numerous products, the "name brand" company is buying from an OEM house and relabeling it. (LCD TV's, Power Supplies, and especially various types of memory)
3. Simply put, just buy from any reseller in good standing - online or brick and morter, and test the memory when you receive it if you should have any concerns at all. As long as you're buying from a known entity that gets scrutinized to death on these boards (such as Sandisk, Kingston, and yes....Patriot) you should be perfectly fine and you should receive exactly what you order.

The benefit would probably be in it being able to keep up with HD video recording, and decreased time scanning the microsdhc card when booting up, or mounting or unmounting it.
Yet, the bigger the card and more data would slow down the scanning. Double edge sword.

Maybe. I depends on how many files it has to catalog. I imagine that a 32GB microsd with 10 2.3GB movies would scan much faster than a 8GB card filled with mp3s
Have you noticed that the card makers are going away from what the Class system is supposed to be. Look at the transfer rates of the Class 4 cards now and they are equal or better than some of the class 10 cards. Doesn't make sense to me, but maybe people didn't understand the Class system and its relationship to transfer rates.
So the Class system is supposed to specify a minimum transfer rate, which increases as the Class goes up.
However, it seems that it is applied arbitrarily by different manufacturers.
Check SD card wiki for more information.
Newegg says they are available
Newegg just notified me that the Patriot 32Gb class 10 micro SDHC is now available. Now it is $99.99.
Newegg also has a Wintec Class 10 32GB for 82.49 - it isn't by Patriot, but it comes with a lifetime warranty.
I have a Wintec 16 gig class 10 in my Vibrant.
Works very well, very snappy performance.
I've never figured out a way to test it in the phone, but thru a adapter on my laptop it hovers around 17-18 meg thruput both read and write.
(edit) BTW, I got it at Frys.
It was 38.99$
Nice price.
Patriot LX 32GB Class 10 benchmarked with SD Tools v1.3

Oh, by the way, about the SD Class system, it only rate the minimum sustained write speed of the card, but not for random writes.
Wow. That's pretty awful if the benchmark is to be believed.
i have a scandisk class 4 32gb , it has a write speed of 4.8 and a read 11.4
Semi-related, I have a patriot 8gb class 10 card that is holding up very well, including quick transfers. Patriot seems to be pretty good stuff, so I'm considering getting a 16 and passing the 8 down to my girlfriend. I don't think I could find a need for 48GB on the phone, except to hold backups for reflashing.

[Q] class 6 vs class 10 sdhc

ok im sorry, i just wanted to confirm something, i'm looking at a getting a new sdhc card, mine is a oem verizon sandisk 16 gb class 2. im looking into upgrading to a 32 gb. i have alota music, maps, cm rom backups etc, and im looking at moving most of my apps to the card.
from what i understand a class 2, 4, 10 dosent mean much difference in the phone, but when downloading files to a computer. i wanted to confirm that the class doesnt mean much in the phone's speed..... this will change which card i go with... sandisk class 2 32gb are roughly 60 bucks and i like the company cause ive never had a problem with them, however the store down the road frys has a wintec class 10 32 gb for 65 bucks.... just wanted to get your guys opinion.... especially since the lenex and kingston are 100 each... again im not talking about the brand im talking about the class
It will make a difference on how fast things on the sdcard load. For instance your gallery will load much faster with a higher class card. If you have apps installed on your sdcard then they will load faster and so on. Now with this being said I have a 16GB Wintech class 10 card and and Adata class 6 card. The Adata class 6 loads everything much faster than the Wintech. My guess as to why this happens is because Adata is simply a better brand than Wintech. Some people have gotten lucky with the Wintech Class 10 cards and some have not. Some Class 2 cards will read and write at class 6 speeds. Is it confusing...a little, but the higher the class for the most part the higher the speed. If you can find a good class 6 or class 10 card it will be worth it, but my advice is to stay away from the Wintech. I have heard also that the Kingston class 4 cards usually are much faster than what they are rated for. If you want cheap, go cheap, but IMO you usually get what you pay for and Kingston is probably the top brand when it comes to microsd cards.
That's not necessarily true. The class rating refers to the minimum write speed - it has nothing to do with the read speed. I recently upgraded to a 16GB class 10 card from an 8GB class 6 card.
The class 6 card got ~7 MB/s write and ~14 MB/s read in SDTools. The class 10 card gets ~11 MB/s write and ~9 MB/s read.
But in general, the higher the class the better the card will perform in your phone.
yeah, higher class cards are only really good if you stream a lot

i know this is only your opinion and im not trying to put you down or anything, but i do believe scandisk is top rated memory card.
i may be wrong, but im pretty sure they have lowest consumer complaints (about card dieing after a month or read and write speeds being slow, or whatever the consumer may complain about)
i have always used scandisk and i, myself would rate them to be the best, but thats just my opinion.

Sandisk, not scandisk.
