Ok people, firstly, forget the thread title. Wrote it that way just to catch your eye
Anyways coming to the point. I've seen in many threads (especially Sense Rom threads) about questions and discussions about Size and Class of SD card.
They were all about buying cards with higher class for better speed and for providing a lag free experience.
Even I was considering buying a new one, so did some research [by research, I mean lot of Googling ].
Decided to share what I learned and in the process help you in your choice.
Trying to be as simple as possible, even to prove helpful to newbies.

WHAT ARE SD CARDS?
Well SD stands for Secure Digital. It is one of the formats of Memory Card.
This format includes 4 types of cards.
The Standard Capacity (SDSC)
The High Capacity (SDHC)
The Extended Capacity (SDXC)
The SDIO (which combines input/output functions with data storage)
And these types come in basically 3 different sizes - Original, Mini and Micro.
Since now we know what are SD cards, let's move on to the Speed Class Rating of a SD card.
What does the Class of an SD card reveal?We usually talk about the speed of cards in terms of 'Read' and 'Write' speeds.
But while assigning a Class to a SD card, only the Write speeds of that particular SD card are considered.
With SD cards, manufacturers generally rate the cards in three different ways.
The first method is through the use of Speed Class Ratings.
For example, most SD cards will be rated at Class 2, Class 4, Class 6 or Class 10.
The number denotes the minimum sustained Write speed for an empty card. So real-time speeds generally vary and are usually higher.

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
The second method is a newer method of the class ratings called UHS (Ultra High Speed). UHS-I cards are much, much faster and can support up to 104 MB/s.
The third method is through the use of “x” ratings. For most computer enthusiasts, this should be quite familiar since it’s just a multiple of 150kB/s, the speed of the standard CD-ROM drive (Oh yeah, that old thing…). Therefore, an SD card with a 133x speed rating should be able to achieve a transfer rate of 19,950 kBytes/s, which is about 20 MB/s. High speed SD cards will sometimes use the x rating as class ratings end at Class 10.
However there's a catch.
The Write speeds used to denote a Class are "Sequential Write Speeds". Well you might ask, whether it matters to a normal mobile user.
The answer is maybe or may not.
Here's why: The Sequential Write speeds or Sequential Access is the speed with which large amount of data of a SINGLE FILE is written.
For example, while transferring data from system to your phone or vice versa, or when a digital camera records large photographs or videos.
However, for a smartphone user, there is another important speed to be considered - "Random Access". This is writing a large number of small files. Random read-write is the most important for speed during normal phone performance.
One study found that, in this Random-Access use, some Class 2 cards achieved a write speed of 1.38 Mbit/s, while all cards tested of Class 6 or greater (and some of lower Classes) including those from major manufacturers, were over 100 times slower.
By saying that, I'm not suggesting that all Class 2 SD cards are good for your phone.
You might wonder, why does Higher Class cards get lower Random Access readings?
Class 2 and 4 cards have better Random Access speed and Random read/write than class 6 or 10 cards in general. To get higher Sequential Write speeds, manufacturers sacrifice the Random Access speeds.
That's just how it is.
Class 6 and 10 cards are setup to initialize the area of the card that is about to be used to make the sequential write/read quicker, but it takes extra time in the beginning to do the initialization. If your using the card where you need to access small bits of info from various parts of card quickly, you will do best with class 2 or 4.
Most people seem to assume that the higher the class, the better the card is for everything, but that's not how it is. Different purposes need different kinds of speed... cards with higher sequential speeds have lower random speeds

How to benchmark your card?
Benchmarks are a rather elusive science since there are too many variables that can impact the results, not the least of which is the card itself. Anyone who has worked with SD cards in the real world has probably noticed that the brand of card can make a dramatic difference in performance. Tests have shown as much as a 12x difference in performance between best and worst cards in real world tasks. As already noted, the "class" ratings used by manufacturers as a measure of performance are not reliable indicators of performance either. In fact, some manufacturer's class 2 and class 4 rated cards routinely outperform cards rated as class 6 or class 10!
Consistency of testing is important since different devices and bottlenecks, such as bus speeds, buffers, file systems and activity can all impact and alter the results. This is why a card that has performed extremely well on a test may turn out to be a dog in your device. Short of testing all cards in a lab environment under exacting circumstances may well yield inconsistent results.
There are a lot of apps available for bench-marking, for Android, as well as Windows and Linux.
Bench-marking Tools
CrystalDiskMark
HD Tune
AndroBench
Others such as SD Tools, Antutu etc.
Few Examples that might help:
Now we come to the question - Which SD cards should we go for?
Well, that's upto you, the end user, to decide based on your requirements.
On my part, I've provided you the information to help you with your decision.
Yet, for those who don't like to take decisions, here's something which might help.
The SD Association defines standard speed classes indicating minimum performance to record video. Both read and write speeds must exceed the specified value. These are defined in terms of suitability for different applications:[40]
Class 2 for SD video recording
Class 4 and 6 for high-definition video (HD) to Full HD video recording,
Class 10 for Full HD video recording and consecutive recording of HD stills
UHS Speed Class 1 for real-time broadcasts and large HD video files.

NEW PROGRAM MADE SPECIFICALLY FOR DEFRAGGING FLASH MEMORY:
Yep, I know, they say defragging flash memory is unnecessary and wears out your SDCard. But then again, a car that can go 160 mph is unnecessary too, but that doesn't mean you don't want it.
My favorite (and free) defragmentation program is called:
MyDefrag << Click to D/L.
You can get it online and it goes on your PC (not your phone):
It has a NEW option that is made specifically for defragging flash memory (i.e., your SDCard). I figured, what the hell and gave it a run.
NOTE: THIS PROCESS CAN GET HUNG UP ON YOU (IF IT DOES, DO THIS)
It took 3 tries to get mine to go all the way through the first time. Just exit out of MyDefrag and when restarting chose the "Kill Current Session" option and it will pick up where it got stuck before.
This probably works faster if you pull your card and put it into a usb card reader. Of course, back up your SDCard on your PC before trying this.
THE RESULTS:
1) Even large galleries populate VERY fast.
2) Music and video libraries load instantly.
3) When adding apps/widgets to homescreens, options appear MUCH faster.
3) NO improvement in read/write speeds (but I didn't expect that anyway because the read/write test is just reading and writing 200 mb of data to empty space anyway).
CONCLUSION:
This takes a while so only do it when you have a spare 1/2 hour or more that you don't need a phone. As far as wearing out your SDCard, c'mon, we are flash-a-holics and are beating our cards to death daily anyway. However, I would recommend doing this only monthly or so.
* P.S. - This is also an excellent defragmentation tool for your PC.
** UPDATE: We have been testing this out over at the MikFroyo thread and members have been getting excellent results.
IF THIS THREAD HELPED MAKE YOUR PHONE FASTER, GIVE IT A 5-STAR RATING ON TOP SO OTHERS WILL SEE IT TOO
Hell, I'll try anything once. Thanks for this.
trying now..i followed it on MikeFroyo post.... .. like he said above . i'll try anything once..... i'm at 94% now on a 16gb class 10...
doesnt seem to be taking as long as some others have......30 mins to an hour ..
edit:.... spoke to soon.. back down to 1% fastfill..hahah
Sometimes it can get kind of hung up. If it does, just close it and start it again. When prompted kill the prior session and it will pick up where it left off. Don't know why it hangs like that but didn't seem to cause problems.
If you have a new card, it is likely not very fragmented yet and will defrag faster.

Just did this on my Wintech 16gb that is about 85% full. Worked like a charm. My gallery loads almost instantly now, before it took about 20-30 sec. The whole process took about an hour and a half(I plugged my card into my reader in my laptop). Thanks for the heads up on this.

If it has an option for defragging flash memory then I suppose so. MyDefrag is free.
Gave this a shot yesterday had to use a card reader and try a couple of times for the software to complete all of the way. My sd card is now Defragmented...did I notice a speed increase...not really but I don't pay much attention to loading times. Makes me feel better and faster and thats good enough for me!

crap... no mac version
Tried it, took less than 1/2 and noticed a bit of improvement. Sweet.
Not bad...but I just want to say you can defrag without using that program. Connect your phone as a disk drive, then right click it in my computer, properties, the tools, and you can click defrag to analyze and defrag it, and all your other drives.

I was thinking the same thing. In the OP it is explained that this program is designed for flash memory to reduce the number of read/write. Flash memory can only handle so many write cycles so I decided to let this program do it's thing to minimize the amount of moving/writing to my SD card. I am sure that one defrag with any program wouldn't hurt anything but I fell better know that the program tries to minimize the amount it affects a memory cards life cycle.
Just as a side note....I don't know if in the long run it matters a whole lot at all....I can't remember how many times flash memory can be written to but I am sure that I will have a new phone and SD card way before I am in any danger or reaching the upper limits.

Actually, this is incorrect. This program is designed to specifically defrag flash drives. You do not want to defrag them in the same way you defrag typical hard drives.
In the future, please read the OP before commenting. This fact is clearly stated.
Thanks for this! Another great idea from mitchellvii!
backing up Sdcard now will test this
just started defragging my 32gb class 4 lets see what it does.
Q: I kno the OP says around 30 min but was size sd was that? I have around 18gb of music and pictures and videos on my card (love me my music anndd my gf lol) just curious if ill get my phone back before todays kickoff

Got a question on how the benchmark works:
I've got three different brands of SD cards here: Kingston SDCA3 32GB, Transcend Ultimate 633x 32GB and Samsung Pro 64GB. All cards have roughly the same speed rating of W80 and R90. And when it comes to read speeds they all get well over 80MB/s, so that's fine.
When it comes to write speeds however the two 32GB models only achieve about 40+MB/s, whereas the 64GB model gets well over 70MB/s.
Why is that?
All cards are exFAT formatted with 128 kB cluster size and changing it to 32 kB doesn't seem to have any effect.
Phone is an LG G3 16GB D855 running Android 5.0.
Any help or information is appreciated.
Thanks in advance

May be a little late answer, but anyway... Card class or rating does not mean anything. It usually only guarantees the minimum speed. The maximum speed greatly varies between cards and manufacturers. Also, not all devices have bus/card reader that can achieve maximum performance of the card.

Cluster should affect Random read/write speed... And sequential usually is almost unaffected. But again, different devices, different cards can produce different results.
Honestly i don't know what i should feel when i use this phone.
Just look at the specification at Sony Official Site
But in fact we got 3 types of memory
Phone memory = 700mb +
Internal storage and SD Card
Even at the official site don't say anything about phone memory , but All Installed apps go to phone memory, what the hell i see here
700mb+ ONLY , what to store exactly ? only installed brave frontier game cost 300 mb , and it can't be moved to sd card or internal storage. What the hell i buy this phone exactly
Feel like got scammed ..
When i got info from my friends who buy samsung note 3 , they don't get this phone memory crap, and only got internal storage 16/32/64 gb and the sd card. And again what the hell i see here...
Really i think that i should buy more better phone earlier than this junk which can't even install 3-4 more games
Or is there any way to swap the phone memory to internal or sd card ? any help is appreciated , i already use link2sd or foldermount but it's like not get any effect since some apps can't be moved from phone memory

It is because of the system apps. Not sure, but i think it is.
And most of the devices has the same way of memory.
Like my galaxy player, it has 8gb memory. 4gb usable.
Now my device memory has only 1.4gb free usage.

So i cannot update any app anymore. What is the easier way to increase App Storage?
Again, i cannot move more app. i've moved all the possible ones !

Phone Storage : User Data and movable Apps 4.15 GB. It is to store user data when no SD card is used.
Not really used if you have an SD Card
SD Storage : You'd better get one...
So i cannot update any app anymore. What is the easier way to increase App Storage?
Again, i cannot move more app. i've moved all the possible ones !
Thanks for your help.

Have you tried
[MOD][HTC One SV] Swap your internal and external memory (sd card)
http://forum.xda-developers.com/showthread.php?t=2306841
Not sure if it is for your model phone so please read the entire post.
Hello.
Sorry, but you didn't read the message.
It's not about switching SD_Card and Phone Storage (that contains Movable apps) that i need.
It's increase internal memory. This memory cannot be accessed from windows and is a linux partition.
Internal memory contains non movable apps : chrome, facebook etc... It's always full.
I don't want to root nor trick the phone i was asking if there was another solution. There is none.
I check my bank account with it and i want to keep it safe.
This phone is a crappy and i'll NEVER buy an htc again.
Regards,

without rooting your phone there is absolutely no solution except buy a phone with larger storage.. the internal storage on this device is the only flaw i had with it but there is an easy workaround that only requires root.. i check my bank to and fail to see how rooting my phone is made it any less safe.. the method i use simply creates the linux partition you speak of on the sd card.. ext4.. and "extends" your internal and this allows you to move your apps to the extended partition thus freeing up as much space as you desire.. i have 32gb of internal space(i grabbed a class 10 32gb sd off amazon for like $15.. boost variant caps at 32 but others go up to 64).. if you are interested go here to an older post of mine.. i would have just included the links here but some new rule doesnt allow me to post outside links because i have less than 10 posts on my account.. again root IS required for this method.. good luck

Does it matter if the card is 30 vs 48 mb/s?

Also I have not modded this phone at all its completely stock with boost.
the speed at which the sd card reads/writes is not a factor.. i personally went with a c10 so there was no chance of lag/stutter when running an app/game from the extended partition.. most apps/games are small enough in file size that the speed shouldnt matter.. you will need to root your device and should always make a backup.. store your backup in multiple locations(computer/flash drive/dropbox/cloud) to be safe if ever something happens to your phone help will be much easier if you have a backup ready to go
Read notebookcheck.net's P7P review and noticed they used AndroBench to test the storage speed so I thought what the hell, I'm gonna do the same. Didn't' fiddle with any settings and just ran the test as is. The sequential write speed is noticeably lower than what the fine people at notebookcheck got (875 MB/s). Also ran PCMark's storage test and the internal & external sequential write speeds were below the expected level.
I am a total novice at this and chances are I'm both improperly configuring/running the tests and interpreting the results. Before running the benchmark I was trying to remedy the so-called scrolling issue so I installed the december factory image using the Android Flash Tool; managed to do that without a hiccup, but now I'm scared the flashing process was somehow detrimental to the P7P's storage health or speed.
I'm guessing the storage drives on phones are resilient and one could, theoretically, flash an image dozens of times in a row without any ill effect , but, as I mentioned, I don't know which way is up regarding this stuff so I'm seeking out the advice of more experienced and knowledgeable users.

That's pretty fast. The real question is in actual usage how much is scoped storage slowing it down and how much increased battery usage is it causing?
Write tests put wear on the flash cells while serving no tangible purpose if only done out of curiosity.
Well, been treating my device as if I had it for years, flashing away on it more than 2-3 dozen times now, but my numbers aren't far from yours. I honestly wouldn't worry much about it.
Interesting. I couldn't resist These are the results from my N10+ N975U running on Pie. In spite of slower memory (12gb) and SoC it did very well on sequential write times. I use to think my Raptor x 4 Raid 0 array was fast...
I'm on the original October Firmware and this is what I get, I've been on all of the different versions (November and December) but I get the best battery life on October. Perhaps they changed some write settings in the November or December firmware.

Interesting... I too flashed the October version this morning and got pretty much the same benchmark results.
Could it perhaps have anything to do with the P7P storage options? Mine is 128GB.

False reading on the sequential write for sure for non raided single drive, I think. Makes me wonder if my benchmark results are valid... maybe... as internal transfers are fast Copy/paste a 1-10gb file and see how long it takes to write it from internal to internal.
Real world speed is all that counts...
Mine is even worse. Running the beta.
Look at the first one I ran too. Eek.
Edit: I also ran another app, CPDT Benchmark, to see if it was just the app. It's definitely not.
Just to clarify my last post: I got the same results on both October and December versions.
As blackhawk suggested, I copy/pasted a 5,3 GB video file a few times to test internal to internal. On average it took around 26 sec, which would give me roughly 205 MB/s.

Random write is faster than random read? This some kind of alternative universe? Or is there something about flash memory that eludes me?

About 24 seconds to copy a 5.2gb jpeg folder.
Couldn't find a large enough single file.
Not sure I trust that app...

Looks like a caching issue.

My drive doesn't reflect that. More in line to what to I would expect. I generally just look at how fast large file transfers go. On internal memory they go fairly fast.
