EDIT: RESOLVED! Tested on different hardware and results are very different: Sequential Read @ 20MB/sec; Sequential Write @ 12MB/sec.
I bought a Kingston 16GB Class 10 card from ebuyer.com and it is no faster than my original Kingston 16GB Class 2 card. So I contacted Kingston support and guess what they said? "Please note that means the minimum read speed have to be with the class 10card at least 10MB/s". Thats £80 down the drain - WTF!!!?
The SD Card Association (www.sdcard.org) states that "Speed Class and UHS Speed Class provide the constant speed necessary for video recording by designating a minimum writing performance". I have pointed this out to Kingston and am now awaiting a response.
So regardless of the often reported compatibility issues with Desires, I suggest that you look elsewhere for your speed fix.
SD Cards and speed tests have been covered a countless number of times on the forum, i dont understand why you went out and bought a class 10 for a htc desire and assumed you would get blistering speeds from general use
My speed tests have been carried out in Windows on my PC. My point is less about how it works on the Desire and more about how it is almost identical in performance to a Class 2, and also Kingston's crappy attitude.
That said, I use RCMixHD and some of the Rom is stored on the card so yes, I did hope to see some benefit.
Do some research before you buy. Complaining afterwards it not beneficial to anyone.
Ever thought of the possibility that you bought a fake card?

I am truly confused by your response!
The card does not perform in accordance with the advertised standard. The manufacturer then mis-quotes the standard. So I decide to inform other people who might make the same mistake.
In what way is that not beneficial?

If it had been bought from eBay or second hand then maybe I would have. But ebuyer.com is a long standing and reputable supplier and secondly, Kingston haven't suggested it as a possibility and prefer to suggest that the performance is acceptable.

Which kernel is your desire running as i recall there being patched kernels to increase sd card speeds by almost 3x. Not too sure if it is a bug fix or an enhancement.

That's not quite all of the story - the class is the minimum writing speed you should get in absolutely ideal conditions - i.e. one large file on a completely unfragmented card. In the real world, you may well get lower speeds, especially if your card is nearly full and/or you are writing many small files.
I've been using SanDisk 16GB Class 2 cards in both my Desires for months, and they've performed just as well as my Transcend 8GB Class 6. There's no way on this planet I'd buy a Class 10 card to stick in a phone - as far as I'm concerned they are really for the semi-professional DSLR/HD Video market.

My testing us carried out under such ideal conditions, using Crystal Disk Mark, using one large file, on freshly formatted partition using 4, 8, 16 and 32 cluster sizes. The Wikipedia page also states that the write speed should be achievable on fragmented drives, but I'm still only achieving 7MB/s write.

Excuse me, I misread. Class certainly indicates write speed. From Wikipedia 'The Speed Class Rating is the official unit of speed measurement for SD Cards, defined by the SD Association. The Class number represents a multiple of 8 Mbit/s (1 MB/s), and it measures the minimum sustained write speeds for a card in a fragmented state [10].'
I would demand a new item as advertised or your money back.
I truly am shocked at some of the hostile responses from some members here!
I thought the idea of XDA was to help each other not to use it as a portal to vent some anger at some poor person!
Sound like they have grossly mis-sold the card there! I get that speed on the phone itself with a class 6 card (also a kingston btw).
I would be very suprised if it is a fake from ebuyer!

I am aware of this issue and I have been using a "read ahead" fixed kernel for a while. But the problem is not with the Desire specifically, as the card under-performs in a PC too.

Then Wikipedia is wrong! Not wholly unusual for Wikipedia either.
http://www.sdcard.org/developers/tech/speed_class/
If I were you, I'd also test again using a different card reader and/or PC before assuming it's the card at fault. If you are getting 7MB/s it's certainly not far off class 10 minimums (which makes it less likely to be a fake IMHO), but you also need to ensure that the bus you are testing over can actually sustain higher speeds.
Regards,
Dave
I bought a kingston class10 16gb card and I must say I'm really impressed with the data rates. around 12Mb/sec writing. (haven't tested read yet => is there a special utility app to perform this test straight on the phone ?)

Yes, that is what Kingston have now suggested too. They have dropped their claim that the Class rating covers only the read speed and have also offered to replace the card directly. It is entirely possible that my internal card reader is the issue so I will have to find another device to test it on.

I tested on a PC as I do not know what the capabilities of the Desire are, i.e. can it actually read and write at over 10MB/s. But yes, there are a couple of utilities in the Market, one called SD Card Speed Tester.

when transfering from a computer to the phone (which is mainly why i bought this card), i get 12Mb/sec data rate write. I just tested with the sd card speed test on my phone, and i get W=3mb/s, R=4mb/s, which is clearly much slower than what i get when transfering from my computer. I'm thinking android has a lame way of accessing the sd card....

In Android, my Kingston 16GB Class 2 card achieves 4MB/s W and 15MB/s R with SD Card Speed Test.
I also test with SD Card Tester, a 100MB file achieves 3MB/s W and only 2MB/s R whereas a 3MB file achieves 5MB/s W and only 1MB/s read.
All very erratic. That's why I don't test within Android.
RESOLVED! Kingston had suggested that these new Class 10 cards were exceeding the capabilities of the i/o device so I tested the card on different hardware at work and the results are very different:
Sequential Read @ 20MB/sec;
Sequential Write @ 12MB/sec.
It is a shame that Kingston had to begin by denying that the card was even capable of these write speeds as this could have been resolved much sooner. But credit where it's due, this is a stonkingly quick memory card!
Thanks to all who contributed.

Hi Everyone,
As it is taking so long to get real 32GB Micro SD's on the market I was wondering if anyone would be interested in buying a SD to MICRO SD converters.
This converters will not be just some wires solder together...but a converter that is nicely packaged.
Provide me with some feedback on the idea.
umm, how could that possibly work? you can't convert something so its smaller
Well maybe I did not state it correctly...
I mean a converter that will allow you to use a standard SD card into a micro sd slot...it will most likely be made of an external connector for the standard SD card then wire it down to a micro sd slot..
I work for an electronics manufacturing company and I may be able to convince my boss to do a test line of a couple...
But before I ask I wanted to see if there is any interest???
I have a Nexus one and really do not want to keep waiting for the 32GB Micro SD...then I do not want to pay $200.00 for it.
So i am thinking if people are interested a converter that can hold a standard SD that is no more that 4MM thick then you can shop around for a 32GB standard SD card for about $75.00 and have 32GB of storage for your nexus or other device...
Again just checking for input...
I'd would be interested, but I don't think there is going to be enough room to fit it and still put the back on!

Hi tomfreay I was was thinking about that...it may have to be something that mounts on the outside of the back cover...if it can be made to be flush against the back cover...I envision a small "bump" on the back...
I use a clear silicone case for my phone so I do not think it will look to bad....
Or I can buy a Seidio extended battery and case..this should allow me to hide the converter inside...but I think it may look worse than just having a little standard SD size bump on the back of the phone...
I will ask my boss to explore one then take pictures of the finished product and post...
Someone has done this already with one of the convertors already available

OK...so where can I buy one? And how much?
32GB Micro SD cards are available and have been for a month or two at least - check out http://www.google.co.uk/products?q=...esult_group&ct=title&resnum=3&ved=0CDgQrQQwAg
Can't see any kind of converter fitting well with the phone and still looking good. Also it would probably reduce transfer speeds to/from the card.
At this stage I can't say I'd recommend getting a 32GB Micro SD card for that matter. Better to stick with one that has a smaller capacity/higher data transfer speed if you don't want to slow down gallery/music apps etc - something between 4GB and 16GB.

DUDE. Seriously. How many times do people have to be told that a PHONE will not be able to saturate a Class 2 (which has a MINIMUM of 2MB/s NOT MAXIMUM) MicroSD card. Classes, DO NOT MATTER when the phone can only access the card as fast as the chipset can. I had a Class 6 with Apps2SD and a Class 2 16GB with Apps2SD and there was NO DIFFERENCE even with the biggest movie file I could play.
Why the crap would you think that less than 1 inch of copper would slow down the transfer rate to anything you can see?? GIVE. ME. A. BREAK. I have 2 METERS of USB cord AND a 2 inch USB cord hooked up to a portable harddrive, and they have IDENTICAL speeds with the same hardware, why would you be able to tell the difference on a phone where that is not even close to being a bottleneck.
Listen, this is important: SD Card Class will NEVER be a bottleneck for any media on our Nexus Ones.
Ya, true; my converter looks terrible, but it fits under a very nice looking Casemate Vroom Case perfectly I would totally recommend one if you're going to get a MicroSD to SD.
Hi Everyone,
I have posted some pictures of my SD to MicroSD Converter and how it looks once it is installed.
Not bad, would be tempted by it if I needed a lot of storage.
well, if we gonna make our n1 bigger.. is that possible to make raid of two 32GB SDHC cards?

Nice Job. DocRambone was going to try this with the 3200mAH battery and cover but I dont know if he was successful.
The custom back-cover that comes with it should have room for this.

Hi Britoso..I was think about putting out the money for the 3200mAH battery...but then I found the case for it was too big...
The mod that I did is something that I think a lot of people can live with..its not ugly..the crystal case fits...and the grip of the phone has changed a little..I find it feels a little better.
Forgive my ignorance I have been on this site for several years now and still do not know everything...what do you mean by "OP"..set me straight and I will place the pictures there..
To All...
Again with this mod the cover slides off like it should...I put a small slit in the cover for the flex cable...and placed protective tape on both sides of the flex cable to prevent damage.
So at the most I just have to buy a new back cover and return the phone to OEM condition.
Oh I did shaved the battery a little by the MicroSD slot area...
If anyone is really interested in this converter let me know...like I said...$200.00+ for a 32GB Mirco SD card...I have seen them selling for $395.00..no way I say.
This mod ran me $82.00 for the 32GB standard class 10 card and $35.00 in parts.. Grand total of $117.00 for massive storage...I say the little bump on the back is worth it..phone can quickly be restored to OEM..
Maybe in 1.5 years from now when 32GB MicroSD cards come down to earth....I will get one..then I will just use my 32GB Class 10 Standard SD in a HD camcorder...
If it fits inside the battery cover it will be safer from movement, dust, drops etc.
OP= Original Post, the first post
You can also Add "Mod" to the title, need to go into the advanced edit mode for that.

BTW, "class" on a (micro)sd card is for measuring _write_ speed only. Hence playing a video will test precisely nothing relating to it's class rating.
And yes, the N1 can saturate the write speed on a Class 2 card _very_ easily.
Anyone still looking for an adapter. I found this:
http://www.ameri-rack.com/APA-TFC1m.html
They sell this directly for around $24 + shipping.
A few weeks ago I took the plunge on a deal for a 64gb microSDXC card from BBuy thanks to Slickdeals for $100. Some users had reported the card worked on their android devices so I went forth and purchased it. I finally got my card yesterday and though my Inspired warned me of a "Damaged Card" upon mounting, a simple format on the phone solved that issue. It's larger than my previous (32GB class 10) card, with no hiccups or issues and seems to perform like a class 6 SDHC card, with the benefit of being reverted back to the class 6 SDXC format for faster speeds in future phones with SDXC support.
Bottom line: This card works with my rooted Inspire in SDHC mode. If HTC releases phones with SDXC support, you know this card will be reused again.
Thanks for your time and take care XDA-ers

I filled it to 55GB only once and it's been that way for 2 1/2 days. No issues at all. Performance seems the same as before but every once in a blue moon it will take a little bit to do a search on files or scroll through a huge image folder (over 1000 images) but that's to be expected, since my old Class 10 PNY 32GB used to do the same when it was nearing full capacity. Playing MP3s or watching movies (MKV, DiVX, MP4s) didn't hiccup or lag. I will erase and refill the card to 100% a couple of times.
I am more than satisfied with this card, but I'm still testing it as it is. I was able to get a second 64GB card from BBuy before they ran out of stock at $99, and I don't know if I should FAT32 it to be used on a tiny USB drive reader or sell it.
I'll post any issues pertaining this card's usage.
Take care
Great!... Thanks 4 the info!
Awesome. I was debating getting one of these for my Inspire. Thanks.
Thanks for the info. I don't load enough media to warrant that much storage space. But if a great deal is found, why not?
if it isnt too much to ask. with an almost blank card could you create a zip file thats about that size, do an md5 of it, then move it to the card, md5 it again, and then transfer it back off and do another md5. just to check integrity?

The OP implies some form of belief that 32gigs is somehow an imposed limit of Android for SD card size. This is like asking you if you are still beating your dog. It has a supposition of fact where none is established.
Since you seem to think that refuting baseless supposition with simple logic is somehow not enough, allow me to educate you fully with information you could have found yourself:
FAT32 is used to format these cards. Why? Because Windows can read it. The 32 in the name has nothing to do with volume size limits, it signifies that the filesystem is the 32 bit version of the old FAT system. Previous versions were FAT16 and FAT. There is an exFAT too, but it typically gets used for thumbdrives. FAT12 was not a MS deal.
A lot of people assume FAT32 has a 32gig limit either because of its name (baseless) or because of Windows 2000 and 98 refusing to format a volume larger than 32gigs (understandable). This was simply Microsoft tossing limits at things that were far below the spec however and the ACTUAL limit for a FAT32 varies between 1 and 2 TB based on how many sectors per cluster are allocated.
So there you have it. The actual barrier is 2TB.
Note that once you pass about 128gigs on a FAT32 volume, you are wasting absurd amounts of space just because of how FAT works. So look out for people claiming there is a 128gig barrier.

If you consider his post not needed then your post is twice as bad, actually it is trolling. As is mine for that matters. Your post ads nothing to the thread except to scold another poster. And for what reason? Was he incorrect? Was he correct? Do you have any info to argue against his statement? Were you previously involved in the conversation of this thread? So where do you get off posting what you did? And if we look back at all your posts, will we find them all 100% informative? I think we all know the answer to that one.
yea instead of calling everyone idiots maybe he could have seen that so far most if not all android phones list as microsd card capable of up to 32gb. has nothing to do with fat32's number in the name, it has to do with manufacturers telling consumers that the limit is 32gb. try to be helpful and not insulting. people have been confused for whatever reason is irrelevant and the OP was helpful in giving people something they can see instead of just a forum post.
this was a good thread giving good proof for people. thank you OP. lets hope this doesnt go down in the sewer, or maybe hope it gets closed so just usefull info remains.
Well..

WOW. I don't know what led you to think my first post was about FAT32 having a cap of 32GB but apparently it hit a nerve thus making you reply with a post that was somewhat informative, but yet with a condescending undertone based solely on assumptions. Maybe making oneself seem more knowledgeable than others while belittling them is a way to show huge levels of testosterone and dominance over the kingdom. Maybe jealous that some members are willing to shell out money for something that may not be a necessity but something they want to tinker with or experience themselves (Hey, it's our money. Let us use it as pleased.)
I wasn't the first person trying the 64GB sdxc card, but I was one of the first to test it on the Inspire. I wasn't sure if the phone was capable of using SDXC cards so I gave it a shot and ran with it and provided my input for other members to make a decision to purchase, go for further testing, or pass on this card, and that was that. No "HEY GUYS I'M COOL 'CAUSE I BEAT THE FAT32 LIMIT LOLOL!!!" or "I HAV INFINITE MONEEZ" or "I AM BETTER DAN YU" or "LOLWUT".
When I named my post "Beyond the 32GB limit" I was only thinking about what the manufacturer and all other phone sites had on their list of specs for Android on the Inspire. This: (Highlighted in the "MEMORY" row)
You took the title way out of context and contributed nothing to the community in regards to this particular post.
Next time I suggest you look before you leap. And lay off the coffee.
As far as the card goes, it's been running great since I got it. When I get a chance I'll do the MD5 checksum test that Darunion asked.
Take care guys

Very well put, the test is not a huge deal im just curious if any read/write errors occur when r/w beyond 32gb on the card. not sure if any sd card software will do that or not. my inferior self can only get a 32gb card LOL
The fact remains that there is no such limit.
When was the last time you put RAM in an old system? It was probably more than what the makers said was the 'limit'. This is the same thing. The limit is how much you want to spend.

i remember putting a 32mb module into a system only able to address the first 16mb. but that was sometime ago and as i remember a few months later a bios update was released to fix that. god the memories (pun intended) lol
I am looking to replace the 16Gb SD Micro SD Card I use in my Sensation given that I have a sudden need for MUCH more storage space now I have switched over to FLAC format music and 1080p movies to take advantage of the extra quality.
I'm curious though, has anyone tried the new SanDisk Mobile Ultra 64Gb SD Micro Card yet? I've been searching for a few days and I have read all sorts of conflicting reports of people saying they do/do not work can read some/all of the available space and even those who say they work till you've used over 32Gb then become unreliable....
I have found a very reasonably priced site but it is still quite a price if it does not work...
I tend to use my phone mainly for listening to music and watching the occasional video on the move and to be honest my class 4 16Gb card seems to run quick enough but just does not have the space I need. Am I really going to see much improvement from a higher class of card with this?
Does anyone have any advice to help?
Yes, I'm sure some have.

True, but can never be too safe (Newegg's counterfeit CPU incident as well as Amazon). And you never really know till you benchmark the product as there has been some shady sites that have sold "authentic" but failed QA products. Meaning products that were suppose to be thrown away but have been hauled/stolen.
Nevertheless this is on slickdeals right now so it should be good.
But yeah pretty good card, benchmarked here:

Yeah I overlooked the 2nd benchmark because the Samsung Galaxy S3 paths things differently, so I'll try to upload another benchmark but they're pretty much 1~3mb/s lower in range. (USB Adapter being 20read/11write).
I'm on CM9 on the Skyrocket and /sdcard/ and /mnt/sdcard/ are the same thing showing the external storage for me and /emmc/ and /emmc/external_sd/ (embedded multi media card) shows the internal storage.
Not sure how ICS ROMs do it but under /sdcard/ I dont see an /external_sd/ and it just goes directly to the files so thats where it gets a little confusing. So the pathing of the ICS, CM9 and Galaxy S3 are a little different.
replaced my samsung 16gb class 6 with this card - just got it in the mail today.
first thing i noticed, was my phone took like a second to do the media scan (i have 14gb of data on it)
with my sandisk class6 card, it would take like 15 seconds.
this one was almost instant, it was crazy
Speed tests:
done almost 10 times:
write: 10mb/s almost ever time, maybe once it was 9.8
read tests: 20-21mb/s
Hopefully they have a much faster sd slot on this one than the s7
Does anyone know yet if the SD slot on this will have UHS 2 or 3 speeds (confirmed the required pins, or seen a speed test off a demo phone with a fast card)?
I am also trying to find this out
Is it having a hybrid Sim slot???

I'm curious. I did a lot with my Note 3-4, V10, and V20. I never noticed any lag in anything running from SD card. I had a 200Gig card in the V10 and V20 and am not sure what was the issue with the SD cards. If anyone can explain what the issue was, I'd be really grateful.

The 32GB is just barely enough for my storage needs for things that can't be moved to the SD card. It was totally unusable for VR since that can't be put on the SD card. Giving out free Gear VR's with a 32GB phone was pretty silly actually. Luckily we still had an s6 with 128 to use the Gear with.
When any storage medium gets more than haf full you start to notice slow downs. It's MORE obvious on mechanical hard drives but it's still noticeable on ssd's an other solid state storage. It's definitely noticeable on the s7. I've done tests where I reset it instal just a few apps and it's BLAZING FAST, then I install my apps, email, texts, etc, fill it up, and bam it's a slug.
I spent 6 months COSTANTLY screwing around with moving things from the storage to the sd card. It's a tedious and annoying thing to have to do. Having come from the s6 with 128 and never needing to even thing about storage it really pissed me off to have to go backwards on my next gen phone.
So then I finally caved in and did adoptable storage. Well the thing is the internal storage is FAST until you fill it - it's still fast, but you do notice a lot of lagging just going from screen to screen. It clocks in the mid 200MBs. But the SD card is slow. I bought a UHS 3 card hoping it would match the internal ram. The card clocks at 280MBs in a uhs 3 usb 3 reader. It clocks in the 80's in the phone when it's empty. More like the 40's when it's filled with photos and music.
So doing adoptable storage means mixing a single volume with 280MBs and 80MBs storage. Which makes the phone EVEN Slower, but at least I don't have to screw around with moving stuff constantly anymore.
The thing is that people clamored for sd storage. I have no idea WHY they clamored for it. It's beyond inconvenient. It's not like you can pull it in and out since it's on the sim tray. And Samsung decided that in order to include it they had to stop making larger storage versions.
I think what we have is a case of be careful what you wish for.
It's far better to have larger FAST internal storage and a FAST usb connection than it is to have the stupid sd card.
That's my rant on this, but here's the bottom line summary:
1. The 32GB is incredibly inconvenient if you are heavy user like me with lots of stuff. Micromanaging the storage makes the phone a chore to use, and the full card slows the phone down a little bit.
2. Using adoptable storage is more convenient, but the slow SD slot makes the phone really really laggy - at least for a heavy user like me.
I've put my s6 128 next to my s7 edge with adoptable storage, and the s6 is way more responsive. I just can't go back to that small screen!! LOL

I've never run out of space on the sd, but there's only certain things that can be put there, so it was always half empty with like 29-31 GB of stuff clogging up the internal storage.
The s7, for people like me, made you choose between convenience and speed. That's frustrating for a phone that came out in 2016. Especially when the 64 or 128 s6 gave you the best of both worlds.
I feel like the 64 in the s8 will be enough that if I fill it it will only be every few months so less maintenance. If it has a uhs 3 reader and does adoptable storage then it's the best of every possible world. Maximum options for the maximum number of use cases.
I saw a Tested.com podcast once where they brilliantly slammed the s7 and the iphone at 32GB. They pointed out that these are the two specific phones where the least technical people are going to buy, and in the end, they are the two phones that will need you to mess with them if you take a lot of pics or download a lot of music. Meaning that for a less technical person, it's better to have the larger storage and that Apple and Samsung needed to raise their bottom number in order to not cause grief for their most common customer: the less technical user who buys the lowest price one because they don't know any better.
I get a LOT of calls from IT customers asking me to help them figure out how to get stuff off their 32 GB iphone or Galaxy because it's full. I hate that call. I didn't get into IT to babysit customer's personal music collection.

Maybe UFS support
Hi Y'all.
If this holds water:

The card bay should be UFS supported like this:

As usual they don't seem to be able to clearly mark the speed of anything. I have a Sandisk Extreme Plus, rated at 95mb read, 90mb write. But it says U3 and V30 on it. Which according to that table can only do 30mb (except it DOES do 95/90), this is due to the quoted speeds for V30 etc being minimum speeds and not set speeds.
Most people also get confused over U3 speeds and UHS III bus type (which has a second row of pins to enable faster speeds but most devices do not support), the UHS III bus has only recently been agreed apparently (https://petapixel.com/2017/02/25/uhs-iii-sd-card-standard-announced-maxes-insane-624mbs/) and there are no cards out yet for it, so youll only get UHS II at best on the S8 and theres no way the S8 will support UHS III. Whether it even supports UHS II, I don't know, it really shouldn't be that hard to tell since it requires a whole extra row of pins but I have seen a dozen threads in forums asking the same question and not a single answer so far, someone even asked Samsung support and as expected, they were useless.
It's like the USB-C/USB3.0/USB3.1 all over again where you need to be a detective to work out whether you get usb 3.0 speeds, 3.1 gen1 speeds (5gbps) (which are often also referred to as 3.0) or 3.1 gen2 speeds (10gbps) (which are often referred to as just 3.1) from a particular cable or device. When these geniuses setting these standards are incapable of even getting the NAMING of these things right, you know we are in trouble!

That's because the naming is done by marketing committee. More concerned with fancy pointless marketing names than really conveying what the technology is capable of. The 'name by committee' factor is in full effect too.

Then they should all be sacked for being useless at their jobs. Marketing is pointless if you create endless confusion for consumers (not to mention the opportunity for scam sub standard products taking advantage of the stupid ambiguous naming). Rule number 1 should be crystal clarity on 'spec x = speed y' with no possible confusion between spec x y or z!

As usual they don't seem to be able to clearly mark the speed of anything. I have a Sandisk Extreme Plus, rated at 95mb read, 90mb write. But it says U3 and V30 on it. Which according to that table can only do 30mb (except it DOES do 95/90), this is due to the quoted speeds for V30 etc being minimum speeds and not set speeds.

It's a minimum of 30MBps. you can probably hit 90MBps if you transferred 1 file that's over 90MB. It would be considerably slower if you transfered 90000 1kb files. Same with all storage mediums.
