[Q] Note sdcard read speed.

Hi,
I am eyeing for the sandisk mobile ultra 32gb class 6. It claims to have 30mb/s read speed which is really impressive.
But does galaxy note sdcard reader will be able to handle 30mb/s read speed? Because for what I know most card reader tops at 20mb/s which is why most cards even those class10 ones has read speeds of less than 20mb/s.
Please correct me if I am wrong.
Thanks.

I don't think Note can handle 30 mb/s .. someone with more insight on the hardware of the card reader on Note might be able to help you

I have 32GB 10 class I can help but tell me pliz how to chech the speed read write?

but that is for PC and as I understand we should get the test on Note with the card inserted ????

That's the 'realism' that I had in my mind. If I have a full 32gb card, and wanted to transfer my pictures and videos, which is what mostly the card will be used up for, how is the transfer speed will be? If I am able to use the full 30mb/s read speed on sandisk mobile ultra card, that can greatly reduce the amount of time to move 32gb of data off the sdcard.
For sdcard application usage within the phone itself, the only thing that I can think of that will use alot of bandwidth on the card is recording full hd video, which a class 6 card is more than enough to handle the write speed. If for read speed, a mere class 2 cards can do 8mb/s read speed which is fast enough to watch your regular hd video, listen to your mp3 etc.
You just can just connect the phone to pc as storage mass and the program will detect the drive. You can start the test using the software.
What is your microsd brand?

k heres my 2 cents, my family has 5 galaxy notes. Basically I tried many brands ranging class 4, 6 and 10. First off the class 4 32g are like 40% or so slower than the class 10's. The 2 class 10's I have are all different brand both 32g and I can tell you they don't really make a lot of diff in terms of speed its less than 0.5mb per sec diff (the slower class 10 is same brand as the Note and the other one starts with Lex???). Then you have the class 6 64g which runs up to around 10% or so slower than the class 10. At the end of the day what you find is class 6 and 10 are both fast but the class 4 are dam slow. On my machine I'm using the 64g card. Speed was determined and optimized by SD booster and SD tools.

Thanks for info, that's alot of GNotes you got there.. your family must like BIG SCREENS.
Anyway, my actual question was, is the GNote be able to handle 30mb/s transfer for the sandisk mobile ultra versions or atleast what is the highest read speed for GNote card reader.
There is one benchmark that I came across somewhere that proves that the card does actually deliever that transfer speed albeit using usb 3.0 port. It takes atleast a regular usb 2.0 reader on a usb 3.0port to achieve it. A usb 2.0 reader on usb 2.0 port barely makes the 20mb/s mark on the same card. So the usb 3.0 port is quite crucial even though a usb 2.0 reader is being used on it.
So yah, the ideal situation is someone actually has the sandisk ultra mobile card + GNote and is willing to give spare time to benchmark it for us and post it here.

Samsung Evo+ 128gb or SanDisk Ultra 12gb ?

I was looking at these two memory cards online. The evo+ 128gb is around £40 and the ultra 128gb around £33. Out of the two which should I go for putting inside my s7 edge. Which one has better performance and reliability.

both are good, go with scandisk for cheaper price.

check this article
http://www.phonearena.com/news/Thes...our-Galaxy-S7-S7-edge-LG-G5-or-HTC-10_id80277
and you have this post about microsd.
http://forum.xda-developers.com/s7-edge/accessories/suggestions-microsd-t3321569
I recommend to take SanDisk Extreme Plus UHS-I U3

Don't get the Sandisk Extreme Plus 128gb. It's $200-$300 and has almost zero availability.
If you want to save money and get a fast 128GB microsd card, go with the Samsung EVO+ (i use this in my S7e).
If you want to spend $100, get the Samsung Pro+ 128gb card.
Both Samsung and Sandisk are reliable.
As far as performance of the two cards you listed....
Samsung EVO+ -- READ 82, WRITE 26
Sandisk Ultra -- READ 92, WRITE 19
Get the EVO+. Write speeds are more important than the read speeds, especially if they are higher than 70mb/sec (both are).

Correct me if I'm wrong but isn't for a phone the random write speed the more important figure vs. the sequential write speed you listed?

Personally id go with the samsung evo.

Only if you elect to use the Adoptable Storage option in Android 6.0. If not, sequential write speed would be the key field.

Whichever is cheapest at the time of purchase. You'll notice no difference once it's in the phone.

I ended up going with the 128 GB Pro + - can be had for $90. Much higher write speeds than the Evo +. The new 256 GB Evo + might match or even outclass the 128 GB Pro +, but at $250... I'll pass.

Best MicroSD Card?

Trying to choose what MicroSD card to get for my Note 9
First is
Samsung Evo Plus 256gb
Link:- https://www.amazon.co.uk/gp/aw/d/B06XFS5657/ref=cm_cr_othr_mb_bdcrb_top?ie=UTF8&th=1&psc=1
Second is
SanDisk Extreme Plus 128gb
Link:-
https://www.amazon.co.uk/gp/aw/d/B07FCMRBTM/ref=psdcmw_1345826031_t3_B07FCMKK5X?th=1&psc=1
Right away you'll notice one is 128gb & the other is 256gb this is because the storage isn't too important, 128 is enough, 256 is the same price..
However the SanDisk one is A2 certified & V30 certified which the Samsung one is not, also the SanDisk has a 170mb/s read Vs the Samsung's 100mb/s read
Will the A2 & V30 certification even make a difference on a Note 9?
Appreciate any help or opinions? Thanks

The impact between the Samsung SD & Sandisk is not so Big I guess. Anyway i have a pro SD card from Samsung in my Note 9 & what to Say? Works perfect.. but if you get more space for same price..i would recommend the Samsung anyway..

That depends on what you're going to store on the SD card. If it's music or data that's doesn't need lightning access, go for 256GB. You're getting 2x storage with same price. 100 mb/s read is not less either.
The premium cards with names like Extreme or Pro advertising more than a hundred MB/s speeds are useful for cases like 4K video recording or RAW (or burst shot) photography.
I assume your Note9 still has plenty of storage to do these stuff. You can always record or shoot photos on internal storage and can anytime move the older ones to SD card if you get low on storage.
As I have said, please do share the reason you're thinking about getting 100+ GB SD card.

Mainly high quality photo's, high quality videos, high quality music often .flac instead of .mp3 & possibly some movies..
You're correct assuming that my Note 9 has plenty of storage left I've only used 29gb out of 128gb, however I prefer to keep music, photos & videos on a removable storage
The reason I'm thinking about getting 100gb+ is because I already have 3 MicroSD cards full at this moment in time, they're 32, 32, & 16 so that is already 80gb in total, so a 64gb MicroSD wouldn't be much use, the next one up is 128gb...
I want to move all the contents of the 3 MicroSD cards & move them on to the 1, easy to manage my files that way
I often backup the MicroSD contents on to my PC twice a month, I'd want that to be fast as possible
It's my understanding that the V30 certification is for filming & saving 4K video directly on to the MicroSD right?, That wouldn't be too important as I'd film it on to my device first then move it later on..
However the A2 certification is regarding read speed right? Which is 170mb/s on the SanDisk compared to 100mb/s on the Samsung, how noticeable is the extra 70mb/s and it what circumstances?

Yes, V30 means the card can sustain continuous video recording at 30 MB/s. You said you're going to record on internal storage itself (and you should be) so that shouldn't matter much to you.
That enhanced write and read speed (with some caching and efficient performance) with A2 can give you higher speeds while backing up the data to your PC but it's just 1.7x with 0.5x storage (not mentioning other bottlenecks for maximum speed). I consider the 256GB to be having far more VFM. Your backup frequency will also get halved with double storage, no?
You can never go wrong with either of these. Premium memory cards like V30 are meant for professional video recorders and camera. Playing even 4K videos requires around 50 mbps and FLAC are under 1 mbps.
I think you should get double the memory for same the price!

Yes I'd record on internal so V30 can be forgotten about pretty much
Could I also expect bottlenecking on the Samsung 256gb?, & yes my backup frequency would probably be reduced to once a month with the increased space
Yeah the V30 certification would definitely make a difference to me if I was using a professional camera etc. But as it's my Note 9 & I'd be saving to internal, I don't necessarily need it
I'll probably end up going with the Samsung 256gb thank you very much for your help!

Yes, by bottleneck I mean the capabilities of Memory Controller and Card Readers.
Upon reading over the internet, I have found most SD cards averaging Read/Write below 70 MB/s. Read one benchmarking here for Samsung EVO+ 256GB UHS-1 microSDXC U3 that advertises speeds over 90 MB/s.
The bottleneck here is the card reader on Note9 as well as the hardware limits.
Even on a PC, the card interface or the adapter (in case you use that) could be bottlenecks.
I think you're going the right way with double the memory with same the price. There's diminishing returns on higher performance with increasing price.

Both are good brands. However if you are probably gonna get the same data transfer speeds on your device as the Note 9 doesn't have a very fast microSDcard writter in it.

I have a Samsung Evo Plus 256gb and it's good and fast. I can only recommend it

Is UFS 2.1 (64 GB version) worth it, over UFS 3 (128GB version) for non-gamer?.

I have ordered 8GB / 128GB (mainly because 6GB / 64GB is not yet available, but it will be soon available as per the news) & it will be delivered tomorrow. My current devices are ZUK Z2 Plus (32GB eMMC) & POCO F1 (64GB UFS 2.1). I am quite content with the performance & data transfer speeds, provided by UFS 2.1 in POCO F1 and never used more than 20-25 GB of storage.
So, is it worth to go with X2 Pro 8GB / 128GB over 6GB / 64 GB(after it is available), considering only storage type (UFS 3 vs UFS 2.1) is the difference?. Any one can shed some light on the real world differences between those two UFS versions?. I know that UFS 3 is almost double the speed (writes / reads) theoretically.

I think for the price difference of like €50 it's certainly worth it.The UFS 3.0 has many benefits which basically make your phone faster and contribute to battery life even,
Opening apps etc is quicker,you download a file for example will be written rapidly to your storage so you can access it much quicker,
Now you may not see a problem with your current 2.1 UFS and it mightn't even noticeable in a lot of situations but I would go with it all day long and your getting 8gb ram instead of 6

Question 8GB LPDDR5 RAM, it is still enough?

I have read many topics about comparisons 8gb to 12gb e.g. oneplus 8 pro etc. It turned out that 8gb is perfectly fine if you are not using 15 applications at once. Do you think that for the SD 888 and three powerful cameras it will still be sufficient?

The 6gb on my s9+ was more than enough for anything 2 weeks ago.
So realistically 8gb will also be more than enough. But if the price difference between 8 amd 12 isn't big, just go for the 12gb so that u can fullfill the placebo effect of a faster phone

A few weeks ago I was still using the Pixel4a with its 6 Gigs of RAM and the so called "weakling" SD 730G chipset. It was enough for me...
8 GB is more than enough IMO. Anything more than 8 GB RAM on a phone, is a gimmick! For the casual user of course. Although not really sure what you'd have to be doing on your damn phone in order to fully utilize like 12GB of RAM hahaha.

8GB is more than enough. If you are a social butterfly and you use fb, instagram, whatsapp, snapchat, tiktok in parallel it will only consume less than 6GB. If you play any game it will still be less than 7GB

The newer ram is about 20% more efficient. No such thing as too much.
My Note 10+ is running on 12 gb of the older generation ram with good battery life.
That said you can see what my current ram usage is right now with 7 gb free. With ram intensive apps that can change. That Android doesn't have to off load much or anything means less cpu cycles wasted and a snappier response.
