Is it worth paying extra for a faster micro-SD card?

Have just acquired a Touch Pro 2 on eBay, and am now thinking about getting an SD card for it. I assume the TP2 supports SDHC...?
I can get a 16GB class 2 card for about £30, or a 16GB class 6 card for £50. Am I likely to notice much actual difference in speed between the two when used with a TP2?

Depends.
In day to day usage of the TP2, no I don't really think so. You're not going to be able to take pictures any faster (the camera isn't capable of fast shooting), movies will run fine from a slow card. Maybe searching through your email would be a bit faster, if you have a lot, but I can't imagine it will be significant.
Where you would see a difference is if you take your SDHC card out of the TP2 and put it into a PC for dumping lots of data on it at once - for example, copying over lots of MP3s or movies. If you're transferring multiple GBs at a time direct from a PC, you will notice a worthwile % increase with the faster cards.
So if you do that regularly it might be worth it. If you tend to change the data on the card only infrequently, then I doubt it is.
Personally I will be getting a slow card. I only have a fast card SD card for my Digital SLR camera, where the faster card enables more shots to be taken per second.

whatever you do do not get a Transcend class6 16Gb card. They are not compatible. I know there's a thread listing card compatibility in the rhodium forum, but I couldn't find it now.

Wow, thanks for the warning, that was exactly what I was thinking of getting.

firstly i beleive the class relates to write and not read speed.
second do not buy a card off ebay whatever you do.
i have come accross an a-data 16gb class 6 in my searches. in the end i got 8gb class 4 from play for a tenner delivered. may get a 16gb if i ever hit the limit. by then the price will have dropped to reasonable level.
i had a 2gb in my xperia and never filled it. i have a ipod touch for music and a netbook.

all the cards i have ever bought off ebay have been fakes.
some have worked but been slow. others have corrupt sectors. some have failed all together. thankfully last time pay pal refunded me.
look at www.sosfakeflash.wordpress.com/
buy the card if you want. that site has programs you can test it with to determine if its legit. i will never buy a memory card from ebay again.

Class only deals with write speeds, not read speeds BUT if the card has a higher write speed, it will normally have a higher read speed as well. (Though it's not a set rule).

Thx for the heads up. I think i'm going to risk it anyways. This seller has been on there since 2000 and has sold a ridiculous amount of flash memory ~20,000. I would hope the system would show some signs of fakery over that span of time.
I will try the tool you linked once it arrives tho.
Thx again
PS here is the ebay item # if you want to look: 380143609813

I decided I didn't really need 16GB of storage anyway, and ordered an 8GB class 6 card - a SanDisk Ultra. Got it from these guys on Amazon UK Marketplace.
They have a pretty high turn-over - nearly 30,000 ratings in the past year. I also used this tool to check whether the card was genuine or counterfeit. It passed with flying colours (no errors at all) so I think it's probably the real deal.
A quick, informal test (copying a 700MB file onto the card) suggested it was writing at about 12.5MB/s when the card was connected directly to the PC's USB port, and about 5.5 MB/s when accessed via the phone (in disk-drive mode). That suggests that the phone might get some benefit from a class 6 card, although it's hard to be sure. Certainly this a is a VERY fast card when removed from the phone and connected straight to the PC. (In fact the testing software rated it even higher - 14.9MB/s write, and 17.5MB/s read).
No reliability problems of the sort associated with the Trascend cards (although I'm not sure that affects 8GB cards anyway).

Trancend 16GB Class 6
I currently have a Trancend 16GB Class 6 and it works just fine.

I only buy cards from Sandisk and usually from amazon. EBay has a lot of fakes on it! I have a 16GB Class 2 from amazon that I picked up for $40. Speed test while in Disk Drive mode through the phone show a Write speed of 3.8MB/s and 6.4MB/s read speed. I have 10GB filled so far and It didn't really take that long to do. I'd say if you were filling the card up with 10GB of new music a day then yeah those speed suck but for a few big loads just to get it started no big deal to me.
I can stream a 800x480 AVC ~1.2Mbit off the card with no hiccups. So I'm not worrie about the speed considering anything more then that the processor becomes the bottleneck not the card.

Do you use your tp2 for music?
try playing a few songs in a row from the music tab with screen turned off...

I just recieved an A-Data 16GB Class 6 from ebay. Seems to be fine, passed memory test with no errors @ 8.9MB/S write and 15.1MB/sec read.
Worth the money just copying video and music files to the drive via pc. Way faster than my previous 8GB Class 2. Don't notice any real difference in the phone tho.

I had a Transcend 16Gb class6 that disconnected if I tried that. I had to reboot to get the card to register in the Phone.

Been out on the road for work all week using music over bluetooth and co-pilot 8 heavily. Working like a charm.....maybe i just got lucky.

I'm putting my $0.02 on the table on MicroSDHC cards. Basically for those of you that want faster data transfer on a larger card like an 8GB or 16GB MicroSDHC, it can make a difference but beware of brands that are not well known and their transfer speeds. The Class ratings on the MicroSDHC cards only apply to their guaranteed throughput rates and are NOT indicative of the actual speed experienced on the cards. I've seen some Class 2 Sandisk cards outperform Class 6 A-Data cards before which is a little scary.

[Q] A couple of questions regarding sdhc card + screen protectors

What's the difference between class? I see class 10 and class 4, class 4 is a lot cheaper then 10 but what's the actual difference? Does class 10 transfer files faster or something?
and also can anybody recommend a good screen protector? I had one come free with my case on eBay but it doesn't even fit the whole screen
Thanks all

Class refers to the minimum read/write speed in MB/sec. Reputable brands actually adhere to these speeds while others are relatively meaningless.

As stated above for SD cards.
And for screen protectors, get Xtreme guards, simoly looked amazing in my One X. Waiting for them to come in the mail for the S3 now.
Sent from my sexy white Galaxy S3 on T-Mobile.

Does it really matter though?

SD speed?
Depends on what you do with that card.
If it's a big card and you often transfer large files to and from it, transfer speed does matter.
If you record HD videos directly to your sd card and your card isn't fast enough your video might stutter or have artifacts.
If you put games on your SD card and those games depend on high transfer rates, you might get lag.
But since the S3 has at least 16GB of internal memory you should have enough space to put stuff that need high transfer rates to your fast internal memory.
A class 2 or 4 sd card should suffice for most people. If you need the high transfer rates though, you'll have to go with a faster card.

Cards get memory lag which means they slower to access files when they filled with a load of files, so ignore the class ratings because a decent quality Class 4 works better in everyday use than a cheap Class 10 even if it can potentially transfer faster.
And files for a phone aren't usually neatly lined up so easily the best value card is Class 6 or 10 SanDisk Ultra then you know your phone can handle anything you throw at it.

Look for a seller with a much higher feedback because there's a serious chance you could get scammed with a fake card there.
But if you find a genuine one that is a good one, but personally I'd spend a bit more for the 32gb card then you know you've always got enough space if your needs change.

People setup new accounts and build up a few hundred fake feedback pm more people are likely to buy from them, I mean I'm not saying by any means this is a scammer but just find another seller with feedback in the thousands to be more safe.
And the only way to tell if it's a fake is run a benchmark in your computer and check the card and packaging look real compared to pictures.

If you only want to watch movies a class10 is probably overkill. The problem is when you want to use the camera to record 1080p movies.
There is a difference between write and read speeds of flash memory like sd cards. They usually are pretty fast when it comes to reading but writing speed is another matter.
You should be fine with a good class4 card like one from sandisk.

what about writing to my internal and copying over to my SD if I need to?

Writing from your internal to your external memory will be as slow/fast as writing from a cardreader to your sd card. Depending on the writing speed of said card.
When your sd card is too slow for direct 1080p recording your suggestion is a valid way to record those videos without lag. Record onto the fast internal memory and then move it to the slower external memory when you need space on the internal one. The sd card will still be fast enough to play the video.
Would be annoying if you had to do that a lot, though. If that's the case you should spend the extra money for a faster sd card.
I have no idea how fast that card has to be. I never had a device that can record in 1080p. However, I'm using an htc hd2 and run most of my apps(including games) from my sd card and in the beginning even the OS. I never noticed any stuttering or lag that didn't come from the OS itself. I've been using sandisk class2 for that and moved to a bigger sandisk class4 recently. No decernible improvement other than that it's a little faster to copy files from my computer to my phone and back, now.
Those cards are rather inexpensive nowadays, especially when we are talking about only 16GB. Don't think about it too much. Just buy one and try. If you have problems with the speed, use it as a flash drive and get a faster card for your phone.

I'm surprised noone has mentioned this yet. But do not buy that card. That auction is for a SDHC card, our phones are only compatible with Micro SD(HC) cards. If you buy that card, you will not be able to use it in your phone. You will need to find a Micro SDHC card.

To be honest I can't even see me using the 11GB you get on the phone unless it's music, an 8GB would do me just fine but I'm going to get the 16GB just in case, I'm only really getting one for rooting

It has a screen that you put over the front, does this mean I'll have to detach the case just to use the phone? The otterbox case looks great and well worth the money after seeing an anchor get dropped without leaving a mark on the case let alone the phone

Micro SD card question

Although not a question dedicated solely to the OGP, i figured others with this phone might also want to know....
I'm looking to get a 64gb card for the phone to store music and whatever else can be put there (I realize apps can't go on the SD). I've seen class 10 cards and other slower classes for sale online. Does the speed of the card make that much of a difference for the uses that we need? I'm assuming that any class of card would be sufficient for music, but then again maybe I'm wrong. Someone please educate me!!!
I realize that with a digital camera, you want a faster card to quickly store the image you just took, so you can get on to snapping the next picture, but with our phones do we need the faster storage that class 10 provides? How much does it matter?
Also, I understand there are apps that swap the built in memory location for the Micro SD location (sorry, I'm an Android newbie and I'm just learning), so that I could have 64gb of "built-in" storage for apps (minus the OS), and 23gb for "external storage", then would the speed class of the card then come into play much? How fast is the built in memory compared to a class 10 SD card?

the thing i can say is class 10 helps a lot for "scanning media" process which comes :
every time you boot the phone
every time you move some media or add some new
before i had a cheap one and it was long....

Built in memory will typically be faster than even a Class 10 card. The other day I picked up a 64GB MicroSD card from Best Buy (half price at $50) and put a ton of ripped movies into it so I can show of that 5.5" screen. It scanned the 50GB of files in a few seconds and I haven't noticed any stuttering, even as I scroll through the videos.
All of the 64GB MicroSD cards I have seen have been Class 10 anyway, so don't worry if you pick up a 64GB. This is the one I purchased (same price as Best Buy):
http://www.amazon.com/SanDisk-Micro...e=UTF8&qid=1371505587&sr=1-1&keywords=microsd
And I do see a few non-branded cards on Amazon, but I would stick with a name brand. There is a reason they are selling for $16.

And, to make it more confusing, I've seen Micro SD and Micro SDHC cards. Can the OGP use both types, and is one better than the other?

MicroSD is anything under 4gb, 4-32= SDHC above 32gb = SDXC. The OGP can accept any of them (up to 64gb).

HUGE Micro SD Cards

First do yourself a favor and tape your micro SD card to the phone with a little piece of Scotch tape. I received the 200GB SanDisk Ultra for free when I purchased the V10 and unfortunately while swapping batteries in the dark the Micro SD card came loose and fell out. Huge bummer given the cost.
Spilled milk aside I've decided to replace it with a Samsung Evo Plus 256 GB micro SD (true usable 238). They can be had on ebay for about $70-90. The 200 GB SanDisk Ultra is about the same. Crazy because these things were nearly $200 early in 2015. I happened to have 64 GB Samsung Pro but quickly filled it up with my YouTube Red subscription and Google Play movies and surprisingly there weren't as many videos as I thought would fit. So I figure go for the big Kahuna.
I decided on Samsung after reading that they had had a better track record with stability than SanDisk.
Anyone else using the 256 Samsung how good is 95mb/s for a power user phone like this? Is there lag? There seems to be a great deal of variance in performance for micro SD which does not entirely square with price.

I am pretty sure most Note 7 users have 256s.... Me & My wife have them installed. Haven't run test. It works... Holds all my pics, movies and roms.

95 (MB) OR (Mb)/s. Huge difference. And I don't know of any phone that will do the rated MB. I usually get 12-25MB out of my 128/200GB cards, usually around 15ish. That translates to about 96Mb-160Mb/s. The new UFS cards Samsung started talking about will probably get close to SATA3 speeds which amounts to around 500MB/s, which in real life will probably mean a out 3-400MB/s and I am being optimistic. Nonetheless when phones start coming out with UFS micro slots they should be as snappy as internal storage, mostly. Random IOPS will probably be a lot better but less than 100MB/s I would guess.
And I am talking about phones. Rated speeds will usually be about 20-50% of advertised speed. Closer to 80% or so in a computer. OEM's tend not put the best hardware for micro SD cards in phones. I would guess because of real estate and possibly heat and battery. Nonetheless, I hadn't planned on buying the V20 but the multimedia capabilites were too hard to pass up and my final cost after promotions and a couple of phone sales will probably be less than $400. If I include amps and DACs closer to $200. My next phone will have UFS for micro slot. No doubt.

Won't UFS come at a much higher cost premium and will the practical speed improvement for phone storage really justify the cost if the prices for these huge capacity micro SD's are collapsing?

ebay... microsdcard.... "remembering buying memorystick and it was fake"... -_-

Just ran a benchmark on my Samsung Evo plus 256. Got 80 MB/s read, 40 write.
Sent from my LG-LS997 using Tapatalk

The new microSDs are rated pretty fast. 90mb/s both read and write
I'm just uncertain if the v20 is able to make use of these speeds.
ie. is the v20 the bottle neck?

If I remember, seeing that UHS 3 cards have two rows of pins on them for faster transfer speeds, but I don't believe any phone supports that second row of pins yet.

Oh yea i forgot to mention that i almost had a similar incident you had. Upon recalling my note 7 I put my memory card in that plastic casting and in my pocket.... somehow the memcard slip out and out of my pocket.. Luckily after searching around I call best buy and ask my old coworkers if they see any memcard around and they did =D... it be bad if they didn't.....

Maybe ill lost this here as I didnt get much feedback in the questions section. I have a 128 gb SDXC micro sd that worked fine on my v10 but isnt even showing up as a option on my v20 . the settings app only shows internal storage. I really dont want to format it but guess might have to . but I have a lot of files on there and don't want to transfer them as even deleted on a computer they still leave a trace

Was that sd card encrypted on the V10? If it was you can only read on the device you encrypted with.

Yeah the reason you see those cards for that cheap is because Samsung flooded the market with 256gb cards with the Note 7 and then S7/Edge promo where they gave them for free. I have 2(one in my V20) and am selling my second one (hopefully today) for $80

LG figured rather than offer another free 200 GB SanDisk card the V20 buyers can buy all those Samsung 256 GB cards flooding Ebay and sell the B&O headphones to offset. Thanks Samsung!

All micro sd cards are compatible with the V20.

I can confirm that V20 can't read micro SD UFS-1. I bought Samsung 128GB micro SD EVO+ and Kingston 128GB micro SD UFS-1, but both can't be detected by V20. I feel very strange and confirm that these two card can be read by V10.

Maximum Memory Card Size For 5T?

I think you should tread the 5T specs first.

The 5T does not have expandable storage.

That's a more helpful answer than the first one, thanks.

damn, why it was so difficult for onplus to make 3rd slot for microsd, always something missing !!
since my first android phone, they always did that !!

Because they want to lost the money from you, just because you buy a memory card, instead of buying a phone with bigger storage from they. Memory card is slower than the phone storage. Just two examples, why they make this decision. The 3rd... the need extra space, for the memory card tray...I know, yes, you say that there is also space on the tray, if you decide to use just one sim... But you need a READER PART TOO... that's extra space... It's better to get a memory card slot for it, but a smaller battery?? I don't think so.

Hey Ben,
This is a little old question but I've just started using the OnePlus 5T a couple of months ago. You can use larger memory sticks and disk drives. But you'll need to convert to FAT32 format first. I just did this with a SanDisk 64gb stick and works great. I think my 128gb 5T is large enough but great to have extra space for movies on flights. If you haven't already sorted this out, I'll be happy to provide you with more information.

its actually because the SD cards memory runs way slower than the phones built in storage memory and would bottleneck your phone. and why on gods green earth would you even need more than 128GB? one solution would be to buy a USB type c memory stick, on that well known auction site they sell at 64gb= £10 or 128gb - £15 as previously mentioned format them to fat32 to make them compatible. most come with type c connector on one end and normal usb the other
