[Q] which micro sd to buy

Hi,
I have ZTE V970 which is dual core with 1G RAM (simillar to samsung S2 in spec),
Which class will be sufficient - the maximum I think of is recording 720 video movies with its average 5mp camera
is Transcend 8G class 4 is enough?
thanks

More the class, more speed will be for read/write things in SD card. Such that when you want to copy 50MB file in SD card or from SD card, class 10 SD cards copies faster than Class 6 or Class 4. Similar is the case in reading data. I guess, you got the point.
For more info about MicroSD cards you can refer this detailed guide about it:

it should be enough, but i'd go for at least a class 6 to be safe.

is there a difference between class 4 companies. I mean is there a difference between sandisk class 4 to transcend class 4, or it should be the simillar speeds?

class 6
there isn's any difference in the writing speed for the same class sd cards of different companies. i'll also suggest you class 6 to be on the safer side. hit thanks if this helped

Actually I would recommend a class 6 or 10, the price difference isn't that great anyway. The speed is well worth the price increase.

You may as well get a class 6 or higher. It's not like they're pricey and they'd do a better job for you in the end. Instead of looking for the minimum of what will work, look instead for what does the job best.

The class IS the speed. The only difference between companies is their quality control. Sandisk has the best quality control, so you're slightly less likely to get a defective stick from them. Its really not a major difference in either case.

the class is a standard set by the SD association. any card classified as a class 4 should be the same/similar to other brands of class 4.
the only exception to this are the fakes (of which many abound on ebay)

I know they make decent ram for pc's, but never tried their memory cards. If their ram is anything to go by i'd say they're alright.

You can buy from e-bay.

Hi, I would recommend SanDisk Ultra 32 GB SDHC Class 10 Flash Memory Card 30MB/s . Its the best.

yes, but it's much more expensive,
I think I will go for transcend 8 class 4 for 8$ or transcend 16G class for 16$
thanks

I would say that u get strontium card...
I hav been using their 32gb & 64gb card for last 4 months...
No issues till date...
Strontium manufacturers the card which many mobile manufacturer themselves use as the internal memory chip of their devices....
Thats a big enough point to trust em...

so I am going on Transcend class 10

I would suggest a class 10, because I previously used a class 4 and encountered many problems and slow transfers. May cost a little bit more, but personally I think its worth it.

Help Chosing SD Card

I have a 16 GB Kingston class 10 micro SD and it works quite fine. Now I am thinking of increasing my storage and browsed the rates of 32 GB SD cards. Although they seem affordable but the reviews for them are quite bad. Is it advisable to buy a 32GB class 10 SD card?.
Further, if yes, which brand would you suggest?

SAMSUNG
Got a Samsung PRO 16 GB C10. There were two variants i.e PRO and PLUS. The PLUS variant is a little costly but if you have got some extra money its surely worth it. The card claims to have a 48 MBPS read speed. What I am getting is a decent write speed ranging from 9-15 MBPS.

If you're using maclaw's roms you can use a 64GB card.

I have a sandisk 16GB, no problem, good speed, works fine !

I have a Transcend 32GB, class 10, kind of like the one you had ozi5783. Bought it a few months ago, but if I knew then that I was going to use CyanogenMod, I would've waited a little bit longer, and bought a 64GB one. Not that I need that much space, but it would just be awesome to have... On the other hand, I guess that then I could store ALL of my favourite things (media) on it, and that's always handy.
Now, as far as I know, the stock phone supports "only" up to 32GB microSD, but like mauam said, with maclaw's roms you can use a 64GB card. Don't know if anyone tried it, though...
Btw, my card works nice and fast, no issues whatsoever... Very pleased.

Just to clear any possible doubt, I use a 64gb card

Well, I finnaly did a test with A1 SD benchmark, and this is the result. I use CM11 by maclaw.
Our phone doesn't support UHS speed, so I'll just buy a 64gb when I'll have the money.
I will try SD booster to see if I get different results and post some screenshots after.

Sent from my GT-I8190 using xda app-developers app

I use a Samsung Pro 64gb uhs1.
Writing speed is about 10mbps and reading is 20mbps.
It works well on Maclaw's roms, but is not reconized on Stock rom.

I have a common 8 Gb, works fine with the Cyanogen 4.4.2. I don't think is worth buying a expensive one.

I have a Transcend 32gb and it works well specially on maclaws rom.

I'm using a Kingston 64 GB SD-XHC class 10 on Stock Rom, and even without root, I'm able to read it flawlessly :good:

I'm using a 32Gb Kingston external card and it's awesome!

I have a Kingston 8gb but I'm planning to buy a 32gb.
Does the size play role to the speed? I read that if you have an external SD card with big capacity, let's say 32gb, the speed would be slower if you compare it with an external SD card of 8gb. Is that true?

I lost my transcend 32gb class10 and I'm back to old 4gb class4 I lost many games

I Have a Kinkston 16Gb HC Class 6 and in have 2048Kb for cache. It Works perfectly on Mclaws ROMs 10.1 & 10.2 and CM11

32GB Class 10's tend to work best for me.

MicroSD speed and the M9 RAW?

I just tested my Sandisk Ultra 16gb with the RAW option of camera, well while it takes only 3 seconds to save using internal memory, with the MicroSD Sandisk Ultra it takes 6 to 9 seconds!!!
The writing speed is about 10-15mb/s with the Ultra.
I was going to buy a 64gb card Ultra but when I saw how slow it works with the RAW (and perhaps 4K recording) I think it will be better to buy a 32GB Samsung Pro that would give 75 to 80mb/s .
What do you think?
Anyone using a Sandisk Extreme or Samsung Pro MicroSD on their M9?

I have Samsung pro 64GB, Raw 1sec, 4K no problem at all, real speed in write going till 74, read 82

I have the SanDisk Extreme Pro 64GB just give me Read @ 90.56MB/s @ Write @ 81.18MB/s from the phone and speeds were similar using USB 3.0 to test the card on my PC before using it in the phone. I used A1 SD Bench from the play store to test it from the phone.
I haven't paid attention to the RAW files yet.

Wow nice!
Looks like it's faster than the internal memory.
I will get a 32gb Pro then

Well the speed I got for the internal memory was 215MB/s for read and 111MB/s for write.

I would recommend you Samsung MicroSDXC 64GB PRO Memory Card. Also other Samsung cards are great.
Very good read/write speeds.

I put a Lexar 128 GB 1000x in my MXP and it is functioning great.

I'm considering purchase of this phone - sounds like support for a micro SDcard works well, so is there any benefit to buying the 64 or 32GB internal storage models vs. the 16GB model? I can capture video and do TWRP backups to the (relatively inexpensive) SDcard, so what am I missing on a cheaper 16GB phone?

Is the Moto X a UHS-I or UHS-II compatible host device? The extra cost of these higher-end sdcards would be wasted otherwise, correct?
Edit - I googled this topic and found this post: https://forums.motorola.com/posts/8cda627ead . In short, it confirms that the Moto X benefits from / takes advantage of a UHS-1 U3 microSD card. @EmperorX makes a good suggestion.
I still want to know if I really want to spend extra for a 32 or 64GB Moto X, given that I can buy a 32GB UHS-1 U3 card for US $15.

Both cards are UHS-I class U3
It does support uhs-1 from what I've read. We'll see, my wife's card gets here on Wed and I'll test out. Sandisk extreme pro.

Can you report on the relative performance of your higher-end microSD card vs. the internal storage? For example:
compare the time it takes to do a TWRP backup of the whole phone to internal vs. the microSD card
Capture full QHD video directly to the microSD card
etc.

Maybe... But don't expect it to. Internal memory is much faster than even the fastest SD card. If you must use your SD card as internal storage for apps due to space, then move low usage apps to external card and heavy use ones to internal
