Micro SD reader performance - Xiaomi Redmi Note 3 Questions & Answers

Hi All.
Just bought an Samsung evo+ Micro SD
It's supposed to have an (up to) sustained of 100mb/s read and 60mb/s write.
Tried it on the PC and I get 75/55 (close enough)
but on the phone, I get 50/11. pretty bad!
I'm have a SD 3GB/32GB running LOS
is the reader this slow?

At least it detects your card. Mine doesn't detect it no more (after 1 year). I don't want to send it to China for repairs because it will be a month before i get to use my phone again and i don't have a spare at the moment so am kind of stuck. Would be great if someone could throw me a repair manual for one of these phones.

Try one of those vanilla AOSP roms. You'll be surprised.
Darkness remix (Resurrection Remix by @MOVZX) is also a good one.

What I need to know is what is the speed, not rom recommendations

probably already discussed, but whats the deal w/ sdhc & dcd's rom?

I'm looking to get a bigger sd card for my xv6800. i want to get a 8gb card to load up on music. 2 questions (pardon me if they have already been discussed, please provide links):
1) will dcd's 3.1.2 rom support the sdhc 8gb cards w/o any upgrades?
2) anybody know what read/write speed our phone can put out? that class card can I most fully utilize?

The capacity that the phone can support has little to do with the rom and more to do with the capability's built into the phones hardware. The HTC 6800 is fully capable of using SDHC cards, regardless of rom.
As for the speed, get the fastest one you feel like, SD is a spec, and as long as you use an SD card on an SD spec device, it should be able to utilize it.
I can't see of many ways you would see a big difference though by buying a faster microSD, usually the faster cards are only used by cameras when pushing large photos into memory quickly. There is very little you will use with the phone that should need any major speed from an MicroSD.
So go to Meritline or something, get an 8GB card, and enjoy it.
Sort of right but,,,

The 6800 stock 2.0.09 ROM would see all of a 2 gig, but only 3.6 gig of the new 8gig until I updated to the DCD ROM. But my friend has the Samsung and when we did the same patches I used on my 6800 to make the 8gig work with the old ROM his totally failed to see the card at all, so I figure the slot hardware was not able to make use of the sdhd driver. So I think that you are right that the hardware must support it, and the 6800 does, but the ROM must also have the drivers for it, which DCD's do.

Newegg.com is another.
so the new 3.x.x dcd roms will see a full microSDHC 8GB ?
if so, that's great news. (FAT32 i assume).
I've been sticking around with my 1GB, but if this is true, I'll have to get one

[Q] HD2 microSD card

Taking delivery of my phone soon.
What's the latest on microSD cards?
Are 32GB worth it? Do they work?
Any particular minimum Class I should get, even if I have to get 16GB?
Thanks

am using class 6 works fine.
I use an 8Gb, class 4 without any issues. Resco is installed on the card.
Although if your going to flash a ROM from a micro SD card use one < 8Gb.
Thanks,
Al
From my experience, it's not the class or size that matters. It's the make. (Obviously a smaller card with a higher class will have faster r/w speeds, but that's not usually a noticeable issue.)
I never buy any SD cards now that are not SanDisk, and I can't remember the last time I had one that didn't work.
Some brands seem to get a lot of complaints.
The class wouldn't really matter if you're just using it to store data/apps.
I use a Nokia N900 and run Android off the SD card. A higher class gives a better speed when running an O/S off of one. But using one to store data/apps wouldn't give a noticable advantage of one class than another.
Obviously the size does matter but depends on what you'll use it for.
Plus for flashing use < 8Gb.
Thanks,
Al
PS. I agree with the brands. I don't buy cheap non-branded ones. Although I've never had an issue with any of the 'cheap' ones.
The size of the card depends on your needs. If you cram a lot of stuff in there or apps, then aim for 16gb or 32gb.
You can find 32gb on amazon from $70 up (sandisk, kingston, dane elec -- those are deem legit 32gb cards) and most of them should give real class 4 performance (even when they're listed as class 2 like sandisk).
For me I like San Disk,but I want to test Toshiba 16GB Class4.The seller told me that Toshiba quality is good also and I decided to buy it.
Never had any problem with file transfer and running android on SD card.
I've used it 4 months now.So far so good.
I use a kingston 8gb class 4.. Never had any issues with performance
Thanks for all the replies guys.
I'll probably run Android off the card initially with the standard WM 6.5 tweaked. Maybe put some SatNav on there too.
As for Apps depends what I come across. For WM I have an old large build of offline Wikipedia and some dictionaries etc.

I had my 8GB SanDisk in my G1 for 2 years, then my HD2 for about 8 months, then randomly one day it stopped working.
If I plugged it in, all of my content appeared on the phone such as pictures. Then after about 30 seconds it would freeze, and then the phone would say no SD card is inserted. I managed to copy all of my pictures across on the PC luckily before it froze.
Granted it was old - but they do fail after a while.

Any chance of a 64GB microsd card working on the Fascinate?

http://www.kingmax.com/product_info.asp?fid=151&mid=185&cid=187&id=2104
Yes, I'm aware that the Fascinate only "officially" supports up to 32GB cards, but is it possible that that was only stated because 64GB cards weren't available yet? If not, would a software update be able to make this work or a smart dev here on XDA? I really hate being limited to 32GB cards. When this comes out, I would love to use it but I'd hate to pay for something that doesn't work.
Given that I can't find any other microSDXC cards out there, and the one you linked to is showing that it's a Class 10 card, I'm going to say that it's not a legit product, even though it is a real company. Will it be supported, only time will tell, but I'd wait until microSDXC cards are readily available.
It's legit. A quick Google search would've told you that.
http://www.engadget.com/2011/05/26/kingmax-flaunts-worlds-first-64gb-microsd-card/
Class 10 MicroSDXC is definitely legit. There are a few cards out there.
Without being an expert on the phone's internals, I'd give it a qualified "no". Reason being that SDXC as a standard was in its infancy when the phone was released, and still a dream when the phone was initially designed (It takes about 6-9 months from prototype to release for these devices). To include the spec for SDXC in the Winter of 09-10 would have been foolhardy at best.
I would say hold off. Like imnuts said it may be a legit product. But being so new on the market why waste the money. As well I would wait until more major companies are making them so you know you have the reliability behind it, like Sandisk.
there is another post in the mytouch 3g forums talking about this as well.

It's not about reliability. It's the fact that the Fascinate most likely doesn't have the capability to read XC cards. They use a larger address table, and unless the device accounts for it, that can't be read by the phone.
If you plan to flash an EC09 ROM, like TSM's upcoming ROM, four 16GB cards beats one 64GB, even though they'd cost more (we still don't know why EC09 borks some sd cards, and according to TSM, their next ROM will also carry that risk, since it's based on EC09).
Another Fascinating post by my XDA app...
Resurecting this thread
any news on this? my Zune is about to kick the bucket and i'd like to use my old GSI as my dedicated PMP to save battery on my GNex. but coming from an 80GB Zune, 32GB isn't going to cut it. 64GB would obviously be less but i could work with it. what I don't want to do is buy one and have it not work. so i was wondering if anyone has tried this already or could try it if they happen to have both lying around or maybe suggest a ROM or something that could enable support, etc, etc. i know it's probably a long shot but thanks in advance for any help.
whoever said if your gonna flash an ec09 rom get a better sdcard...listen to him. Save yourself some trouble and get a class 10 card if your into flashing especially if you like to flash new stuff alot.
I'm currently using a Sandisk 64GB Class 10 (UHS-1) card without issues in my Fascinate. Running AOKP Jelly Bean Milestone 1. No idea if it works on stock.
The only thing that you need to do to get it to accept the card is to format it to FAT32. exFAT will not work. In windows you will have to use a third-party partition program since windows won't allow you to format the card with FAT32.
I've filled the card to 45GB with no problems so far. If I run into any issues later I'll make sure to come back and let you all know.

[Q] How to keep your micro SD card Healthy. Extending the life...

Over the years I've owned about every brand of cards from eBay cheapo's to the best the industry has to offer like Samsung. I shoot HD wedding videos, take millions of pictures and edit so micro SD cards have been a necessity.
It just dawned on me today when I was looking at the mountain of SD cards I have in my office and realizing the life span on all the cards I've used over the years. Therefore, I'd like to share my experience along with asking those who are knowledgeable in the area of memory cards to help answer some of my questions.
I shoot HD videos and take lots of pictures on my Note 3 so having a reliable card is very important to me. Currently I'm locked and loaded with a 64GB | Class 10 | SanDisk microSDXC UHS-I card in my Note 3. (I also have a Samsung 64GB PRO Micro SDXC | Class 10 Memory Card (MB-MG64DA/AM), which I use in my Canon Video Camera and it is by far the best card out there. Period.)
The 6 most reliable cards that I've owned throughout the years: (Best to Worst)
Samsung
A-Data (Samsung chip, go figure. However, they are highly likely Samsungs '2nd hand' chips as they are not as fast as the actual Samsung brand labeled chips.)
PNY
SanDisk
Kingston / Sony (tie)
Transcend
It's not worth listing the other non-brand ebay junk so I've left those out.
Lately, I've been very disappointed with SanDisk's quality. Especially with their Class 10 cards, where I have found them to have a very weak 'integrity' in their chips. A good card should give you about a million write cycles. (Write cycles is a whole another can of worms...)
I have had more failed SanDisk's (lemons) cards than any other brands combined. This is why I will never buy SanDisk again and am switching to what has never failed me, Samsung. I can't afford the chaos and hate having to recover priceless wedding pictures from a card who decides to kick the bucket when you need it the most.
Recently my 64GB | Class 10 | SanDisk in my Note 3 decided to go belly up and I had to use a data recovering software to salvage all my 4,000 pictures and hundreds of HD video's. WTH right? This card is a couple months old. My previous SanDisk in my old Note 2 did the same thing after a couple of months.
ME, MYSELF AND MICRO SD CARDS...
With a new card I reformat it to Fat32 with Disk Utility (Mac) and then pop it in my device.
Since I take a lot of pictures / videos, I connect my phone to my computer (Android File Transfer, works flawlessly on Mac), copy over everything to my hard drive, back it up again if it's important and then properly eject the phone/card. I've always read and heard from camera guru's that it's best to reformat your card from the device instead of deleting the pictures in the folder from your computer while it's still connected. Therefore, after copying over the pictures/videos I would immediately eject and delete directly from the phone. The 'theory' surrounding this is that if you leave your card connected to your computer, it will access (checking byte order/changes) the directory more times than you would want it to thereby decreasing the life expectancy of the card.
Now of course it's not convenient or practical by no means to do this every day with your Note 3...most people just plug in and play with no problems whatsoever throughout the life of the card.
QUESTIONS FOR THE GEEKS
Explain the difference in the structural integrity of the internal SD card vs external SD card.
How much more life expectancy / write cycles does the internal card have vs an external card?
For a heavy user like me I have always put everything on the external card to avoid using the internal memory as much as possible avoiding unnecessary stress.
How often should the external card be reformatted for a heavy user like me where I'm constantly copying over, deleting, etc...
To be continued...
I don’t know about card in deep technically but all I learned so far, generally cards these days have very long life span, at least average 10 years, unless physically damaged or any uncommon technical issues.
I too concerned about this too earlier but now technology is so fast upgrading you shouldn’t worry about its life span. Technically what I know its life span also depends on it read and writings like you said and even if your car had heavy use then there is no point to formatting it frequently. Card is not like windows which creates junk files by time. Deleting and formatting does the same thing and both will free up same space if you delete all, where formatting read or write more data than deleting. So formatting frequently could reduce its life but that could be unnoticeable. The same way defragmenting, shredding also reduces its life. But shredding is good if I lost it any other couldn’t restores any private files.
So I think there have no logic to format it frequently to keep it healthy, unless its corrupted.
By technology is so fast upgrading what I mean is like, few years back I brought a new phone and brought the best card at that time, it was Samsung 32GB class 6. It was best on the market during that time. But then class 10, pro, plus released. Then when I got note 3 I had already a 32 GB card but I brought a class 10 pro one due to the HD recording. So after 5 years from now even if this card is working I will still have to buy a new one, as there will be far better technically upgraded one. I hope I make sense.
And I too use Internal memory very less, as loads on internal memory make the phone slower.
Thanks for the reply. I agree that with a decent name brand of a card, the life expectancy shouldn't be too much of a worry. My experience with SanDisk has been pretty poor in that I don't think they make cards with good quality material. As mentioned, the structural integrity is very weak. Their older cards were better. The newer ones in my opinion and from my experience have to be treated with a mentality of 5 years ago, because they do wear noticeably.

I know that feel of losing data, I have had 3 64 GB SanDisk cards die since January - right now I am using a 8GB. sad n true
Wow, sorry to hear. That sucks. Then again, you've verified my point even further about how crappy SanDisk cards have become.
Let your next card be a Samsung. I'm weeding out my stock of cards, heck I've given some away already.
Here's the best: Samsung 64GB PRO Micro SDXC | Class 10 Memory Card (MB-MG64DA/AM)
I use it in my Canon and it's extremely fast.

I never used any SanDisk card on phone, only Samsung cards so I’ve no personal experience and I’ve seen many user complains about its compatibility and issues on Samsung device. However I’ve been using a SanDisk high-speed MMC card on my Nikon SLR over last 5 years and still its performing great.
I believe Samsung cards works great in Samsung devices. So far only one card got damaged many years back and that was a stock Nokia card.
I currently have a 64gb sandisk class 10 in my phone I always used sandisk and never had a issue. I can't say the same for kingston. I found out it doesn't mess up when you unmount it when taking it out. I never did that before and they got messed up even if it did get messed up warranty is always there.
currently using the sandisk extreme plus 64gb card with no issues whatsoever. will update this thread once it crap out on me (it probably will in about 6 months) and how the warranty process goes.
I had a 32Gb Sandisk Extreme die in my Galaxy Note 3 while recording 4k video on to it.
Without a compatibility list and guarantee from Samsung, I am reluctant to buy another high end microsd card.
I am sick of these SD Cards. In my Galaxy S3, the thing would ocassionally take a dump and have to be reformatted.
Now I just restarted the Note 3, and boom, card took a dump.
I think I'm going to just live without.
Sandisk has always been reliable for me, apparently there are only 4-5 chip manufacture, and majority of a-data's card are rebadged from sandisk, same goes with transcends, whiles kingston are with toshiba, and PNY is a mix of sandisk and toshiba.
For data recovery and/or SD card repair, had anyone given Spin Rite a try?
I've been using a UHS-I 16GB Team card in my phone, been pretty reliable so far and gets pretty quick read/write speeds. Also been using a 32GB UHS-I Samsung card in my Sony NEX-5T camera, also been having no issues.
Just had my first Warranty experience with SanDisk. My 64 Gig SanDisk Ultra had crapped out by not allowing any write cycle this would not allow for deleting files or format or any changes to card. After a brief chat session on the SanDisk website I had my RMA and got emailed a label to print. My old card was off to SanDisk. 10 days later the new card arrived. This was a good warranty experience. Hope the new card will have more writes.

I'm glad I'm not alone on this. I have my first 64GB microSD on Jan last year. I chose Sandisk because I believe many of tech experts favor them over every other brand. At the time I wasn't at all concerned about its lifespan because I am using it for such a simple task like music storage. By the end of Dec last year, the card refuses to write and format. Folks at Sandisk forum suggested to use SDFormatter, however if you get "write protected" error, your card is not repairable, they say.
I was lucky to get a new one so close to the end of my one-year warranty. But seeing Sandisk cards are getting less reliable these days, I might give Samsung a try if my Sandisk fails again.
Quick question, though: where else does Samsung evo and pro differs beside speed? Does pro have longer lifespan?
Interesting. I've been using Sandisk for well over 10 years in everything from my DSLRs to my phones, never had a single card die on me.
I have owned 3 64GB Samsung MicroSD's over 2014 and they all died within two months.

I agree with you, sandisk is probably the most reliable brand available.
Been using sandisk when the first had them as transflash.

Lifespan? Didn't know they were supposed to "die", or even wear out, and stop working eventually. Been using this same SD card for the past 2 years, and works like the first day I got it.

[Q] MicroSD Suggestion

Hello everyone, I've just realized I have no SD card on my 32GB D855 with stock Lollipop 5.0, rooted ant twrp recovery (even though today I've done a backup with Nandroid it said it had saved it on my SD ?).
I've read somewhere that there are compatibility issues with these new smartphones, so I'll just ask here before spending money on something that might not work
Another question: is getting a >32GB card worth it? I have still 10GB on my phone memory and I don't store films or stuff like that, but I have started modding the phone so maybe I'd better get something with more storage than I think I would need atm.
I should also mention that I live in Italy so some models I've seen in other threads might be too expensive (Kingston, Samsung and SanDisk are the most common ones I could get here). I wouldn't go over €40, but if you say 32GB is more than enough I'll happily save that money for something else.
I have a 64gb Samsung in mine. Got it from Amazon
32 gb seen enough for you. You end up with a 64 Gb device.
I always buy Sandisk.
