I tried searching for a xfer rate of the Touch to its microSD card but couldn't find anything. Can the Vogue/Touch utilize the faster speeds of Class 4 or 6 microSD cards? Or is everyone just buying regular speed cards? Thanks.

Yes it can use the faster cards. There is an onboard driver for SDHC, allowing the faster transfer. Get the fastest and your Touch will be much happier!
Booting
I've heard that the non HC are better for booting.
Love to know if this is true.

They are better for flashing ROM and radio, but that's their only advantage IMO.

Hi,
does the Wizard have a maximum transfer speed for access to the miniSD card slot?
I'm looking for a miniSD card, and thinking of whether the Wizard can take advantage of the very high speeds of the latest cards. Is it worth giving the extra money to get a very fast card or not?
Is 150x about the fastest available?
AFAIK 80x is the fastest available miniSD
Im using it (1GB 80x)
Maybe we can do some benchmarks? any good software to test memory?

Don't bother spending extra money for a high speed card. Even going back to the earliest days of PPC's, it's all about the PPC's I/O to the media card. The only real advantages of a high speed card is when using with a digital camera or when using the card in a card reader.
I have a Sandisk 1gb card that runs just fine in my K-JAM. On my 2750, I have a 1GB Lexar sd and 1gb Lexar CF.

You won't be able to use the full potential of fast cards. Please read http://pocketpcmag.com/forum/topic.asp?TOPIC_ID=17921 for my article on all this stuff.
I'm glad I found this thread. I've installed some software onto the miniSD card and I noticed they load slower. The worsest problem is now the soft keyboard selection menu takes a full 7 seconds to pull up. I was thinking about buying a faster miniSD to solve this problem, looks like I'll just have to live with it.
I got a 32Gb MicroSDHC class-10 memorette card.
I verified the speed with a card reader + h2testw that write speed is : 14.7MByte/sec
read speed: 17.5MByte/sec
But when I used the class10 card in tmobile HD2, I am shocked.
When I copy a 720MB movie the write speed is about 4MByte/sec.
h2testw program when used on hd2 connected to PC, showed write speed as 4.8 MByte/sec only.
It needs to be noted the same card when tested with h2testw and a card reader gave 14MByte/sec but gives less than 4.5MB/sec on HD2.
How to fix this problem of HD2 microsd card speed!
Looks like HD2 usb controller has some problem.
the card is indeed class-10.
Please let me know a solution to this problem on HD2.

The HD2 doesn't read or write to sd cards at that high of speed... that's why it's pointless using class 6 or 10 cards in a HD2. I think most phones are like that. Class 6 and 10 cards are mainly used for digital cameras, where having high sequential write speeds matters.

I have earlier used a nokia 5800 xpressmusic phone with a class 6 16GB card.
The data transfer speeds were higher than HD2.
Generalizing from a single instance (HD2 scenario) may not be correct.
I'm going to go with that the HD2 does not transfer faster than 5.3 MB/sec between the PC and the phone regardless of what the internal transfer rate between the phone and card is.
Using a class 6 card myself, i have noticed that the phone is much more responsive than it was with the class 2 card in there and movies play without stuttering from the class 6 card and applications launch quicker.
my nokia n81 8gb did 8MB/sec from internal 8GB and so did my KM900. The KM900 did 6.2MB from the same classs 6 card
I was under the impression the HD2 maxed at 16 gig. Maybe that's the problem?
Like zarathustrax said, the HD2 isn't capable of read/write any higher than a class 4 card. I think somewhere on the EVO forum there's a fix to unlock the read/write capability for a higher speed but I dunno if anyone here has tried the fix, or if it even works for the HD2 at all.

This is not true. I've copied large files at over 10MB/s directly to the phone. I can't vouch for every hd2 though as it's quite possible they have different hardware. Also the speed drops dramatically if you're copying many smaller files.
I am thinking to buy memorette 32 gb microsd class 10 for my HD2.
As far as I have understood:
1) No matther what I cannot use it fully Class 10 speed when connected to HD2
2) When I connect it to my PC with card reader I can fully use class 10 speed.
I have sandial 8 gb class 2. When I connect it to my pc with card reader and transfering large amount of data (150+ MB), it cease to operate. I have to reconnect it. Then I shuld transfer in less amount of data or reduce copy speed (such as UltraCopy) . I think that is a safety issue for preventing disk from get burned. My question is, will I possibly have some issues with memorette or some other class 10 cards?
Also would it not better using class 10 card in HD2 for using on SD installed Operating System instead of class 6 or 4?
I would appriciate if someone return about memorette. I have never heard about that trademark. I am planning to bid on ebay today.

A good quality class 2 or 4 sd card is usually better for running an operating system off of, as lower class cards tend to have faster random access speed and better random read/write speeds. Class 6 and 10 sd cards are designed to have a higher sequential write speed, but to achieve these higher speeds, the card initializes the part of the card that's about to be used. The initialization takes some extra time to get started, but boosts the sequential write/read speed so it's great for digital cameras or writing files sequentially.
But when it comes to using the card to run an OS off of, like android or wp7, or using the card to run apps off of, you are going to be reading and writing many small bits of data from different parts of the card. When it comes to this, you need a card that has a good random access speed and random read/write speeds. A high class card that is tweaked to have high sequential read/write speeds ends up being slower because it keeps initializing each part of the card before accessing it, while the lower class 2 or 4 card that doesn't do the initialization is a lot quicker accessing many small parts of the card because it doesn't have that extra step... but they don't get the speed boosts with sequential read/write.
Many people just assume that a higher class card is always going to be better, but this isn't true at all. It all depends on what you are using the card for. Higher class 6 or 10 cards are perfect for digital cameras, recording video, or transferring large files, etc... if you are going to be doing sequential reading or writing, higher class is better.
But for running apps off of, or running an OS off of, or using it as internal memory for an OS like wp7, or anything that will be accessing many parts of the card quickly or reading many small bits of data, etc., you want a card with a good random access speed and random read/write speeds, and that is something that is not rated on cards... but generally lower class cards are better than higher class cards... especially if you get a good quality brand, like sandisk. Sandisk class 2 and 4 are very good cards for random access speeds.
I hope some of you find this info useful and stop assuming a higher class card means better for all situations.

You must be special then. In my tests I had no difference in a class 2 and class 6.

I am using memorette class 10 32GB microsd currently.
Its affordable and is fully working. I have tested to full capacity read/write using h2testw as I wrote in an earlier post.
Just check the seller's feedback and the description though.
I use TEAM micro sd class 10 on my hero,but after a month my sd card write speed is only 2MB/s.
At the first time,it reach 11MB/s when i tested it with h2testw and sd speed test on my handset.
I only use 640MB for app2sd (ext2) without swap cache.
Could someone explain to me what was happen to my sd card?
Sorry for my bad English
I have a micro sd 2gb card , its class 4. And i have problems when i install some roms with data on ext, and similar.. so i will buy a new one.
i need an advice from you.. Which card should i buy so i can get that my hd2 works normally with rom with data on ext ( i mean that the partition sd card to be the main memory for all that stuff on phone) ?
Which class and size?
thanks

Size depends on your usage, you'll have to judge for yourself. I personally would stick to class 2 or 4, they perform as well if not better than class 10 cards for running SD Android, class 10s are only really good for large file transfers. Far more important than class is brand from what I've seen. SanDisk and other branded cards perform much better than unbranded cards (although this obviously comes at a higher price too).
I'd be very grateful if you could explain the contrary between this:

I don't have class 2 micro sd card. Comparing class 4 G.skill and class 10 Sandisk on HD2 they are almost the same write speed to 5MB/s-7MB/s. but testing on PC, the class 10 is faster can reach 10MB/s write.
... but as we all know by now, the raw write speed of the card is no indicator of how well it will perform, since most files accessed are in the 4k filesize range, and many class 10 cards have TERRIBLE 4k block size read/write speed, whilst lower class cards ( 8, 6, 4) usually have better 4k random read/write speed.

Basically what samsamuel said. If you have the time, you could also read this thread from ny_limited, which explains a lot about SDs. It's in the Android general though so I don't know if it'll have anything about specifically running an OS from the SD card. Either way, he's very adamant on the NexusHD2 thread that class doesn't necessarily matter.
I search around website but couldn't find the specific specs for the micro sd card reader for Shield TV. Does it support UHS-II? I am planning to purchase the Lexar 1800x and want to make sure if I can take full advantage of that card which support read speed up to 300MB/S. I'm also wondering about the writing and reading speed of original storage on 16GB version.
Nvm I contacted Nvidia support, only support UHS-I class 3.

I assume all the card reader of UHS-1 class3 should have same limit...based on the wiki the limit for that is 104 MByte/s.
I did some further research and seems like random writing and reading speed is actually more important than sequence speed. However, the review on amazon shows Samsung pro plus is best on both random and sequence speed so I guess I will just go with that for now. Laxer is actually only good at reading speed.

thats a pretty misleading article, there compairing a 128gb evo plus to other various sized cards. from what ive seen (so far) all premium 128gb cards have relatively low write speeds vs their smaller counterparts.
lexar's generally have the best sequential read/write speed, samsung's usually are better with random read/write, and sandisk is definitely solid too.
for example
lexar 64gb 633x sequential read/write 93.36 / 48.09 MB/s
lexar 128gb 633x sequential read/write 73.17 / 22.16 MB/s
results are basically the same for other manufacturers.

Definitely a fast card read/write was a bit faster than 80/40 MB/s iirc.
I haven't ran any legit benchmarks on shield yet, but regardless of the sd card i haven't really seen write speeds over 12-15 MB/s while transferring from internal to sd with file managers, ES specifically.
So im thinking internal storage isn't particularly fast, just like on the shield tablet. If i get bored I'll run some tests and see what I come up with
I haven't found a device that's not a camera that support this format yet.
^^ yeah pretty much. even if they call it out. real world speeds dont seem to get there. outside of HD cameras
The microsd reader is UHS-I so you will spend money for nothing. No matter how fast the external storage is you still depend on the speed of the internal storage which is gong to be the bottleneck when you run the OS and apps. 4K video needs 25Mbps and UHS-I can deliver easily. Same story if you read from USB 3 ports. I don't know the speed of the internal storage but it should be at the commercial level of the beginning of 2015.

what's the maximum speed of the micro sd card reader? write and read speeds?
I know some android phones are kinda limited. like having 20mb/s maximum speed so it was no point buying a 90mb/s one.
I would like to know what's the lg v20 limit.

Not sure what exact limit is but there are 2 threads on here already about micro SD cards speeds. I suggest going through those to get an answer.
Also bear in mind that alot of those advertised speeds are theoretical speeds and you will most likely never see that speed under actual use. At least in my experience
if it would answer my question I wouldn't be making this thread.
