I have seen various makes / models on the market and I am thinking about a
SanDisk Ultra II 512 card
Does anyone have any experiance of this model

512 SD card
what about a 1gb card has anyone got any suggestions on which one to get the o2 data support said that there are 1gb sd cards out there but all they've tested is up to 512 mb. They are firmly against the MMC cards but they couldn't explain why. The MMC card is cheaper.

The 1-GB SD cards only became available for purchase a little over a week ago.
The MMC is cheaper because it has a lower maximum transfer rate. But I have found many stores where the price of MMC and SD cards are the same.
Ultra II sd cards as far as i know only run at ultra speed if your sd-slot support it
ok guys any idea
how much a 1gb sd disk will cost, compatability and where from
cheers john

As far as I know, the only 1-GB SD card brand available now is SanDisk. The price is around US$395. Other brands will soon follow.
with the price of 1GB compared to 512 and 256 then i'd rather have more cards and switch between them like
1 for goat and sheep p0rn collection
1 for mp3 music
1 gps maps (if i had a gps device)
1 for programs

totally agree
as only one has just come out it's likely to be quite expensive
but if people keep a look out they can let us know when other models come out and where to get the best prices
failing that they could swap their donkey porn collection that takes up less memory !
I use a Kingston 512mB SD, works well in the XDA II, no speed problems or loss of data. I use it mainly for camera images and large data files but also for my regular backup (Sprite Backup Premium) and several applications which I don't use often.

I have a 512mb ultra ii on order, for quicker access to gps maps and voice etc, and should receive it next week. I'll try to post back here when I've tried it, assuming that there is any discernable difference.
frankly speaking I use regular sandisk 512MB SD card only due to high price for everything with Kingston sticker on it, IMHO kingston has not been manufacturing memory cards for years but branding other manufacturers products, including memory ...
one thing that is of interest to me is .... whether these sandisk ultra II SD cards are really faster and to waht extent, especially considering the fact what is the SD card port in XDA / XDA II, i.e. what is the internal port speed limit as compared with new and speedy cards ??

I've just received the ultra ii and although I haven't USED it yet, here are some benchmarks...
Internal Integral SanDisk Ultra II
Read MB/s 1.55 0.13 0.20
Write MB/s 0.10 0.02 0.68
Min Read ms 0.25 0.25 0.25
Max Read ms 1.50 9.75 8.5
Ave Read ms 0.32 4.14 2.43
Total Read ms 813 10368 6089
Min Write ms 0.25 0.75 0.28
Max Write ms 165 108 6.75
Ave Write ms 4.87 28.85 0.72
Total Write ms 12310 72246 1810
I've only done a quick test abd should really have repeated them several times and taken averages. However, this clearly shows that the Ultra is built to WRITE FAST, even blowing away my XDA II's internal storage.
sandisk 256MB
I just bought my second sandisk 256MB works fine for me, i bought it for my new NAVMAN 4410
I use a Kingston 512Mb
Works great, using it mostly for watching divx but I also have some music and GPS maps on it. In Sweden Kingston is much cheaper then Sandisk.
The only strange thing is that Im only able to use 488Mb...
The card was preformated so maybe thats a reason...
Steves digicams did a big test some time ago on compactflash memorys and the ultra memorys wasnt always faster. I would save the money and buy regular, its fast enough for the programs in the XDAII.
/miki
seem to recall that all sd cards give you less then they are labeld because of the secure encryption features which make SD cards different from mmc cards apart from being a bit thicker
has,nt anybody got any price,s?
I paid £129 through eBay.
Sandisk 512 Mb for € 159,-
www.geheugenkaart.be
So around £129 for an Ultra II or around £107 for a 'normal' one - I know which one I'd rather have!
thanks i think its time i get my wallet out.hehe
I need 1 gb SD-card for my MDA-II. Which SD-card is the best in concern to write-speed?

I dont think you can use 1MB card on your meching, but if you can i dont mind buying one as well
You absolutely can use a 1GB SD card in the II - I have been using a SanDisk 1GB SD card in mine for several months now and it works flawlessly. It is not the fastest card available, but I have never seen any adverse performance from it. Granted, I do not watch movies with my II on a regular basis.
Is there no comparision available of the write/read-speed of the different 1 gb-cards??
not that i've seen try searching on google
or try looking in the benchmark part of pocket mechanics if they have some 1GB cards there
I'd alsolike to buy 1Gb SD CARD. Does anybody now if the following are any good and if they would work in a XDA1
http://www.memory4more.com/show.cgi?inhalt.htm has 1GB SD-Card Fast 45x Transcend Ultra Performance 45X for 103Euro +tax +shipping
http://www.aria.co.uk has brandless 1GB SD CARD for £48.5 + shipping
2 512 or 4 256 would be a better path imho
first of all with the few 1GB cards the lack of competition would mean slow speed and high price
higher then more of the other cards
a flash card have a limited number of writes before it join its ancestors in the world after having a flash card of 1GB is a bigger investment so having it being worn out is more of a drag
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!)
Hi All,
I just wonder why most of PDAs including Hermes have a very little RAM. Is it because the memory for PDA is very expensive or because of something else? I don't mind to pay an extra $100 if they can increase the RAM to at least 1G. iPhone can have 8G, why can they made 1G PDA
hi mate...u can use 8Gb micro sdhc on your hermes you know...why pay extra 100$ for 1G???and with my experience, a memorycard + card reader is WAY FASTER than any internal memory...cheers....
Some of applicantions can not run in sd card or run faster if you install in internal memory. 64MB is too small. The latest HP iPAQ 110 still only has 64MB. Is there a reason why they can not increase the memory?
Note that the iPhone's 4/8Gb is storage, equivalent to the memory card slot on a PDA (which the iPhone doesn't have).
Several iPhone hacking sites put the actual RAM at 128Mb, which more than a few PDA's and smartphones already have.
They (HTC) and they will do it. Its just a matter of economics. They will increase the memory to get you to buy a new PPC.
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?
