will type II compact flash work in the xda II? Seen 2.2 gig for under a £100
Only if the backpack accepts this type.
cf is slower then sd right ?
cf or sd
technically, cf are faster than sd and sd are faster than mmc, that is if all are the regular type of cf/sd/mmc, not those 16x or 40x type...
cf are originally used for highend digital cameras as they are relatively big in size, sd are the replacement for mmc, smaller than cf, but slower.
in terms of functionality, cf has more functions. all these are based on my passed observations, it might not be 100% correct, pls correct me if there is any mistake.

Can we use the Sandisk 'Ultra' line? If yes, does anybody know if the faster transfer rate of the Ultra card is supported by the XDA?
try using pocketmecanics it got a benchmark tool
and that seem to show that
the xda2 at least use the pretty slow intel xcale internal sd interface
making the xda1 faster when it comes to sd speed
with mechanics you can compare your result with a list of pda's with different sd cards
non of them ever reach ultra speeds
heck they dont even reach the max speed of normal sd cards
if you compare the speed with the same card in a SD card reader
but that dont mean there is not difference in speed
like Sandisk is the slowest thing ever
I'm using a Panasonic 512MB SD Card and it's supposedly faster (and better) than the SanDisk Ultra.
YMMV
Hi guys!
I've got 2 512M SD memory card:
- Sandisk UltraII 512MB
- Panasonic High speed 512MB
...and I've got 2 device:
- i-mate Jam (QTEK S100)
- Canon PowerShot SD300 camera
Waht's the difference between the 2 SD?
In your opinion the speed are identical?
Is it better to put the Sandisk into Jam or into the camera?
Hi
I read a long discussion about SD card speeds on this site ages ago.. as i understand it, PPC can only read and write at a FRACTION of a slow/normal SD cards read/write speed, so it really makes no difference.. might as well put the biggest, cheapest card you can in it as anything alse is a waste of a memory card...
My own limited experince with a few sd cards i have (bog standard up to sandisk xtreeme III) shows no difference in speed across the cards.
Lovely caemra you have by the way

Well... I understand that in ppc I can put the slower one but...
Sandisk Ultra II vs Pnasonic highspeed?
What is the faster? (I'll put the faster in my camera!)
I am perhaps hours from buying HTC Tytn..and from what I can see maximum size you can buy is 2 gig. Compared to my pocket pc (which had an sd and cf slot), I can put up to 4gig cards in its slot. I am going to really miss having a bigger capacity for extra programs, and memory for files. If they do come out with a larger Micro SD,, lets say eventually 4gig for example, do you think that all it would take to be able to adopt this new size would be to to a ROM upgrade (update) or is it written in stone that the max on this unit is 2 gigs.
Thx for any input, and especially any enlightenement in regards to larger micro sd's that are on the horizon.

AFAIK there is no 2Gig limit and 4 gig would be OK, but lets here from others.

Anyone know if that will work on a hermes device?
Is MicroSDhc a different incompatible standard?
I dont think wm device do support sdhc system so we are limited to 2 gb or at maximum 4gb but no sdhc....
i will be more then happy if anyone can prove me wrong...
PS:just a note somewhere i read that the maximum possible capacity for micro sd is 32gb but im not sure is it obtainable with sd 2.0 specification (sdhc) or with standard sd 1.1 specification....??
SDHC cards don't work in normal SD slots, like the Hermes has one. There is hope for non SDHC 4GB MicroSD cards though, because there have been 4GB SD cards and now also 4GB Mini SD cards available, that are non SDHC compliant and work in standard Pocket PCs. So let's hope for non SDHC 4GB MicroSD that will work in our Hermes.

While the headline might seem familiar with the same keywords of Samsung producing 128GB flash storage modules, this story is different from the previous one. Last month, Samsung announced a 128GB storage based on the new and anticipated UFS 2.0 standard and targeted for flagship high-end devices — it made its debut in the Galaxy S6 and S6 Edge. This new module, however, is based on the established eMMC standard and it will appear in mass market mid-range devices.
If you missed the previous explanation about the difference between eMMC and UFS, you should know that eMMC is the de-facto standard for storage on smartphones right now. It differs from the swanky UFS 2.0 in two areas: it can't read and write simultaneously and it doesn't have a Command Queue system to sort and re-order the tasks it needs to perform. By comparison, it is slower than UFS, but it remains significantly faster than external MicroSD storage.
Samsung's new 128GB flash uses eMMC 5.0 (there's a newer 5.1 standard that is slightly faster), and can deliver sequential reading speeds of 260 MB/s, random reading at 6000 IOPS (input/output per second), and random writing at 5000 IOPS. It is a "value-focused" module and the company's aim is for "mid-market smartphones [to] be able to increase their storage capacity to 128GB." There's no word on when this module will start appearing in phones and tablets, but you should hear about 128GB devices from Samsung and other OEMs later in the year.
It's worth noting that Samsung also highlights the speed gains compared to external memory cards in its press release, so you might want to take the hint that the company's devices that will be equipped with this new flash module won't have a MicroSD slot. Financially, it makes a lot of sense given the mark-up difference that added built-in storage incurs compared to external storage. And Samsung can rake in that extra casheesh instead of sending it SanDisk's (or Kingston's or other companies') way.

Complaining about the lack of micro SD is still a thing? I thought we went over this... multiple times...
It's time to accept the reality that all of the S6 versions will not have micro SD. If you need a micro SD then simply grab another phone.
I don't buy it. Does that mean USB OTG isn't going to work, either?

I actually am not bothered by lack if sdcard support as long as bigger storages wont be overpriced like hell. Anyways personally, for me speed and responsivness > sd card support

There's nothing in the software which prohibits it from being discovered by a file browser. It works but read/write speed in the music/video player apps is slower than if the files were on the internal storage themselves.
So, is this a confirmation on a feature which may or may not exist, on a phone which doesn't currently exist?
The SD card was an issue when the phone only had 8 or 16 GB of internal storage. Now that the phone has minimum 32 GB with an option of having 64Gb (of much faster storage) for a manageable price I don't think the SD card is a problem anymore. Most people i know only use a 32 GB SD card anyway.
Looks like USB OTG will work fine:

It was supposed to be a joke.
Samsung's Galaxy S6 Active may come with a microSD card slot, but at a high cost
Reddit user “garshol” sat down with a Samsung rep a couple of days ago to discuss the new Galaxies, and the Active was among the topics at the table. The ruggedized version of Sammy's latest flagship will boast “similar” hardware under the hood, according to the report, and will come with an SD card slot. However, it will also come at a cost – according to garshol's posts, the Active's camera will be a lower class than the one on the flagship model, but at least it may still have OIS. Additionally, the endurance model will not have a fingerprint scanner, and will lack a heartbeat sensor.
http://www.phonearena.com/news/Sams...-microSD-card-slot-but-at-a-high-cost_id67615
These tradeoffs would be acceptable to me. I'm curious about what the dimensions and weight of the phone will be.
I've read a few comments on some sites that suggest including an SD card slot and its associated controller slow down the overall performance of a phone, even if there's no SD card inserted. I have no idea if this is true, but if so, I can at least understand why the S6 lacks SD from a performance standpoint. I've assumed that Samsung's assertion that SD was too slow for the S6 was because they didn't want benchmarks/comments that the built-in internal storage is lightning fast, but SD card is still slow. More of a "we don't want any suggestions that ANY aspect of the S6 is slow", even though most users are well aware of SD's limitations and are primarily interested in simply having the ability to easily expand the storage space despite it not keeping up with the phone storage speeds.
I definitely will not be getting the S6 due to the lack of removable battery and lack of micro SD slot. I think that HTC and LG are going in the right direction here.
Can someone provide some insight about this total mess? I got this Huawei P8lite (or P8 Lite? damn hipster names!) and no idea about what faster and bigger capacity microsd card supports!
Android Pit, CNET, Car Phonehouse and XDA says 128GB.
Ubergizmo says 144 GB (16GB+128GB?)
Notebook Check says the specifications are 32GB, but it worked with a 64GB SDXC card.
Phone Scoop says "up to 32GB".
GSM Arena says it supports 256GB.
256GB can be too much space, but I find convenient to use the phone as some kind of HDD and use some syncing tool (Syncthing, Dropbox) to have all files on all my systems and backup online. I'm worried about those slim microusb connectors, something I need to solve
What's the maximum speed this device is able to support? I'm unable to locate it too? Why isn't specified? How to locate it? Sandisk Xtreme PRO has U3 (UHS 3) and supports reads up to 275MB/s* and writtings up to 100MB/s, for example. Can this mobile support it?

It can support class 10 and above sdcard(I inserted a slow sdcard so it showed a notification that use class 10 or above sdcard(on emui 3.1) . I think 128 GB the max capacity.

Thanks for your input, it's greatly appreciated. What capacity that SD card had?
Yes, it said the same here. I know that's going to be an issue, as I want a massive SD card for different stuff.
Are there someone that casually has big SD cards (128GB+?) and wants to do some tests? What about speed tests?

I don't really use that space. I am fine with 16GB class 10 external SD card(the slow one was class 4 8GB). I don't think this phone can handle 128GB sdcard well since it's a midrange phone. However I can ask Huawei care center about this.
@Suleiman01 i think it should, i have the G play/ Honor 4x (same hardware specs than p8 lite, except internal storage, battery and screen size), and it says max support 64gb, but a 128GB sdcard works too

Then you are right. But it might not be able to handle 128GB+ sdcard. I have emailed Huawei lets see what they say.
Basically it can support all sizes but depends on the file system used. I have a Sony 32GB Class 10 which by default was formatted in FAT32 and i have formatted it to exFAT and it works great on my P8. If the phone supports officially at least 64GB cards then it'll support bigger sized ones because SD cards with capacity of 64GB and up by default come in exFAT file format so this means that it can support higher capacities. Here's the proof
If you are going to buy one then go for the fastest possible or you will have stutters while listening to music and doing some file transfers at the same time. ????
I have a Sandisk 128GB (Obviously formated to FAT32) and works good as hell. All SD cards formatted to FAT32 should work.

What about using EXT4 instead? I use Linux.
Ive never seen a microsd card formatted to ext4. Bigger cards are formatted to exFat which is the formatting that a lot of phones dont support and thats why they say thay they dont support sdcards over xxxGB, but what they actually dont support is exfat. Thats why if you format any size card to FAT32 it will work on any phone regardless of what the manufacturer specifies as the maximum sdcard size. Also ive heard EXT4 is not very nice on flash memories since it wears them out very quickly because of indexing, but I might be going way far here.
Edit: Anyhow linux will support FAT32 so i dont think that makes a problem
@pilililo2
It would be very interesting to know. I know EXT4 provides extensions for SSDs and such since years, but not sure about flash drives (that it seems to use some kind of "HDD emulation in them", right?).
There's this 2010 article about what's the fastest filesystem for cheap flash devices

SDXC cards are mandated to be using exFAT (just like SDHC cards have to use VFAT, and indeed this is the only difference between the two) by the SD card standard. If you don't use this, you are strictly speaking
in violation of the standard and the cards might not behave as designed.
In particular, the card is allowed to only do efficient garbage collection for the access patterns that you get with a single exFAT partition that spans the entire card and has all its metadata aligned exactly in the way that the spec defines.
In practice, things tend to work mostly ok with other file systems, but if you use NTFS or ext3 (rather than ext4), you are usually asking for
trouble.
The best longevity would be provided by f2fs, which is designed to work fine on most SD cards. The downside is that it only works on relatively modern Linux kernels (3.x or higher).
I would expect that cards today use only dynamic wear leveling, not static wear leveling as real SSDs do. This means that content on a read-only partition will decay with the normal life of the card (several years, but depending on the quality of the card and the environmental conditions, e.g. not too hot), independent of the presence of partitions you write to.
Dynamic wear leveling works best if you have a lot of unused blocks, so a good strategy for long life would be to leave a whole partition (e.g. 20% of the size of the writable partition, the more you have, the longer the card will survive) that never gets written after manufacturing, or at least gets erased using the fitrim ioctl command after the initial imaging.
For a 128 GB card with 115GB of actual space, you could then use something like:
* 80GB zisofs/cramfs/squashfs for static data
* 30GB f2fs/ext4 for writable data
* 5GB unused space for wear leveling

You very probably already know that exFAT is totally owned by Microsoft and that there's a leaked GPL-based.exFAT driver for Linux kernel, but this filesystem it's patent encumbered and not merged into mainline.
Why do I mention this?
Because it's a pain in the butt to use it across operating systems and needing to use a custom kernel on your Linux box makes things harder.
I know many custom ROMs with custom kernels use exFAT and very probably even official kernels too, but that's a gray area. Phone manufacturers are able to pay the Microsoft's Android Tax if they want to.
Sooo, what about the bus speed? Is p8 lite compatible with UHC 3 even?
