Flash storage to blame for sluggish smartphone performance says study

0. phoneArena 17 Feb 2012, 22:49 posted on

The Georgia Institute of Technology says that the type and brand of microSD card used on your smartphone can be the difference between a handset with zippy performance, or one that runs as though it is covered in mud...

Something is off with these numbers, what class cards were they using for this study? I have a 16gb Sandisk class 4 card and on my photon, Angry Birds loaded the game rather quickly then it suggested in the study.

lol i have that same card.

sucks because the class requirements change between manufacturers. so they only matter when comparing the same brand. but im happy with the class 4 from sandisk.

Trust me it does. I swapped out my card for a 16gig (the fastest sd card available at the time) and really good performance increase. 720p videos were coming out less choppy

I've been meaning to buy a new 32 GB card, but I just don't think its worth the money. I've been able to save space to make it reasonable. Maybe if they release a NFC enabled SD card with good speed and a lot of space

I will have to agree with it. I have an S2 i9100 and I used to have an Micro SD cars installed in order to save some space sometimes the apps didnt load correct I have to take out so it would recognize the apps. My girlfriend has an infuse and has the same problem. I guess you could use them to save music or docs but in my experience not suit for apps

Agree, My Evo that came with an Samsung 8gb C2 often messes up from time to time when I restart my phone, forcing a restart. But it's probably because I've filled up my entire card with apps and it would try to boot them all at once on start ups.
I should really clean up my phone considering it has 4 pages filled of games but I'm just too lazy and awaiting GS3.

that is why microsoft and apple dont allow you to insert memory cards.

I dont think this is the reason why apple doesn't allow you to add your own memory stick lol they make millions more by forcing customers to buy extra built in storage every time they get a new apple product

No it is purely a money thing.. to change a basic design, it takes 1000's to change the tools, add is a decent card slot and the contacts, holder etc required.. and the you have problems with a suitable cover, and all the support issues arising from this...

Apple have shown already that their engineering skills are not up to much, otherwise they would have known about the problems with RF antennas at the design stage!!!

so NO, they do not want extra problems from their idiot users, who are happy enough just to buy another phone..

The way it is sold, and the way it is bought, is not just a phone, more a 'fashion accessory', upgraded every year ....

No this is certainly not why apple doesnt put a micro sd card in three iphone,apples reason is for money where they try to get as much wool from their sheep as possible,after all you can get a decent 32gb micro sd card online for about 30 bucks but apple charge up to 100 bucks extra for a 32gb iphone compared to a 16gb model. Using that ratio apple would charge 200 bucks for 32gb memory while a good old sandisk 32gb card is 30 bucks

part of it might be due to performance but you have to also think about money too. Do you think Apple would be able to sell many 32 gig iPhones if you could just get the 16 gig and add a 32 gig card?

I don't see any lack in performance when I use the 16gb provided with my dell streak in an xperia x10a or in my new galaxy s2. All of them loaded anything I stored to them almost instantaneously.

Ive used both a class 4 32 gb micro sd card in my phones and also a class 10 32gb card and i found any difference in speed to be minimal between the two or even between the phone with a card inserted or without a card,the phone was blazingly fast either way. Dont think this study in the article holds any real value and was time wasted

is this for apps that are loaded on the external SD? I see where he has an internal set as well as ram. How does he get the device to load ram only and not from the internal? Since the internal is pretty much just an SD card in most phones, that cant really be a category on its own since it would differ from phone to phone. Also, where are samsung micros? thats a pretty major brand to miss. Also, Im shocked at kingston.. they are normally a really good brand.

Internal memory is not an SD card . More of an SSD . Example try playing a game on a thumb drive on your pc , isnt it slower ? Lesson : store music , docs , photos but keep apps , HD vids off your SD card

thats not always true. Sometimes its just an SD card. There was a windows phone.. actually i think it was the HD7, that u could take apart and literally switch out the 8gig internal SD for a 16 gig SD and reformat it to WP7 and use it. I dont know if all windows phones are like that, but obviously some phones are.

Just pure logic tells me to not store apps on a removable microSD, it's like installing windows on a usb pen. I see this research as a new style of propaganda, an indirect justification of a product lackage. I'm starting to feel paranoic lol...but all seem to fit in the mosaic I call "brainwashing of the 21st century".

I'm curious to see soon a research telling us that using itunes improves life quality.

This is why Apple doesn't use sd cards and android makers are now following their lead along with windows.

I wish they would have put class ratings on these cards. I recently bumped from a class 4 to a class 10, and it's astonishing just how much faster it is. Not much difference between a class 6 and a class 10, but it's silly they didn't include that in the graph
