SDHC 4Gb on Blueangel with AKU3.5

Guys, I know this has been asked before - I just cant seem to find a conclusive answer. But here goes;
Will a SDHC 4GB SD card work on my Blueangel with Helmi's BA WM2k5 AKU3.5 (v.1.4 )? Has anyone got one working?

Hi J_Hutt
I have a 4gb SD card in my BA and it works just fine.
http://en.wikipedia.org/wiki/Secure_Digital_card
Untill reading your question and the wikipedia page above, I wasn't aware that my 4gb card was an SDHC card. My card does not show an SDHC logo, but from that wikipedia article it seems all cards >2gb are SDHC (1024byte blocks as opposed to 512).
We are of course at the mercy of wikipedia here though, its information is not always perfect.

Thanks for that, tho I gather the SD"HC" cards are different to the standard SD and not all devices are compatible (same form factor, just something about transfer rate / capacity / Fat32 file system etc)
Is anyone using a SDHC card in their WM% Blueangel?

As I can understand, there are some 4GB SD - non SDHC cards. Google for TS4GSD150. Or read this: http://www.hjreggel.net/cardspeed/index.html#special-sd.html - section "SD and SDHC Card Size Overlap"

Yeah I am aware of that (non SDHC 4GB cards) Situation is that I bought a 4GB SD (not SDHC) card online and it was DOA (not just in my BA, but in readers etc)
Supplier has just emailed me offering to replace it, but do I want a SDHC at no extra cost blah blah....and I am thinking, why not if it will work.
So, again...has anyone used a SDHC in their BA?

You can get it, and if it doesn't work on BA you will have a good excuse to buy a new smartphone...

Hi thingonaspring,
which card you have (brand, model..)? I would want to buy a 4gb's card for my Q9090. What I can buy?
Thx

4Gb SDHC card doesn't work
Not that long ago, I bought a 4Gb SDHC card and not knowing about SDHC (thinking it was another marketing term) and even though it was working fine in the cheap card reader on my desk, it did not do anything in my BA.
Went back to the supplier and switched it for a regular SD card and that one has been working fine since.

SDHC cards
SDHC cards are 3d generation SD card technology,
They have some abilities,
1 to 32 gb capacity
Improved read and write speed,
Data stability,
Content encryption etc..
This technology requires hardware support which device will use, there is no software support. ( Except USB 2.0 cardreader used computers. )
Don't buy SDHC cards, there is already normal 4 gb SD card from SanDiskand kingston, and future 8 gb will coming.
Thx.

That's a bit shortsighted IMHO, 32 gb isn't all that much these days.

i found this when i was searching. If anyone found a regular 8 GB SD card please post it here, i'll be tempted to buy it for sure because it seems like thats the best way to go. Overall if you do get the BA to accept this type of card it wont be compatible in other older devices thats currenly out now. So i think buying a SDHC Card isn't a good investment right now.
But please don't let me change anyone's mind, I'm just looking for a good investment right now.

SD Card info ... from the Windows Mobile Team ...
Everything you wanted to know about SD Cards, but were afraid to ask:
http://blogs.msdn.com/windowsmobile/archive/2007/01/12/everything-you-want-to-know-about-sd.aspx
The SD Standard used by the PPC phones at present does not support larger than 2Gb by definition. However, some 4Gb SD Cards will work in the BA, but this depends solely on the block-size which is being used by the cards.
Your mileage may vary ... try before you buy, and if you do find a 4Gb or an 8Gb one which works (and gets 8Gb of storage - not overlapped!!!) then post the brand/make/model here, as I'm sure many people would love to take their music collection along - a.la.ipod style ...

I have a knockoff SanDisk 4Gb from ebay that works in my BlueAngel (wm2003SE)
I also have the Transcend 4gb 150X card that worked fine. The card itself has problems, which is why I swapped to the knockoff.
beware that some usb readers are not able to deal with 4gb SD cards (notably the Lexar 12 in 1)
If your reader is IDing the card as 900 and change MBs your reader is struggling try another.
I have had no problems with the HTC unit and the cards. The transcend was messing up the same way in the device and every reader I threw at it...
Good luck

Incorrect, I just posted about this. SDHC format can handle much more storage than 32 GB, however there are physical theoretical limits to flash memory, just like there are those for CPU's. My post

There is no incorrect comment.
SDHC is an 3 generation NandFlash technology.
Now, The limit is 32 gb at this time,
Mean of limit is Secure, stable and usable.
May be some firms reached this limit (however you know more than 32 gb I don't now) but not this time.
There is only 8 gb cards on sale and 16 and 32's are coming in 2007-8.
Why i write 1-32 gb?
Because, there is no 512 mb SDHC but well 1 gb SDHC, you may find it.
What is SDHC, why not compitable with standart SD cards.
#1) Disk write and Read functions and commands are changed, New SDHC cards can write upto 6-10 mbps to disk and 50-80 mbps Read from disk. ( I sad disk them, they have no unique name ). This differents come from his hardware structure -->> I/O Busses, Voltage levels, frequenties and other reasons.
#2) They have a chip, he manage reading and writing operations, they have no processor, may you say DCU ( Data Controlling unit, that is mine ID ).
#3) They developed with NandFlash 2.0 technology, This is third of Nano Sized Memory blocks technology. ( You may find somethings about it ).
At the and.
SDHC cards are not compitable with SD 1.0 and 1.1 platforms, not like bluetooth 1.0 and 2.0, there is no old format support. ( No one has been sad yet )
if you want to buy SDHC, be sure the compatibility.
Blueangel's SD 1.1 slots have 1.2/12 mbps speeds ( Write/Read )
"This is not maximum speed of SD 1.1 they reached 2.1/25 mbps on USB 2.0 cardreaders."
The numbers may be some wrong, but be sure they are nearly values.
And lastone.
CPU's are not simple units. And they have so much parts.
You may find somethinks like of this comments in the Internet.
Just search it.

Come on ppl buy buy buy
http://search.ebay.com/search/search.dll?from=R40&satitle=8+gb+sd+card
Just leave one flash drive and the 8GB combo for me. When your done just let us hear the reviews

Well perhaps "incorrect" was a bit harsh. It all depends on where you get your info. here lists the ultimate capacity under the new memory addressing scheme as 2 TB. Where as here the maximum size is listed as 32 GB. Now I did mention that there are physical limitations of flash memory, and may not be able to reach the 2 TB limit, but under the SDHC standard, 2 TB is supported.

This is what I had read also. I had done some little investigation into this a few months back, so I'm no stranger to searching the web, and had done so back then and once again. With that said, the second link above actually had some new info. It lists SDHC readers as being backwards compatible. Where as what I had read sometime back, was that there were legal restrictions imposed by the SD group to prevent this. Perhaps this has changed now. Well I suppose I may be defending a bad premise, because to be honest, when I had originally searched about SDHC, I didn't come across the 32 GB limit. And I suppose I could have been more specific about what I was referring to in your post.
Regards,
Jason

Good but...
This is mine last post about SDHC.
32 is Maximum reached SDHC capacity at this time, 2 TB is only theorical limit.
When someone make 2 TB SDHC then you can say the upto 2 TB capacity.
May be 2 TB SDHC's will come in future, then we can talk about 2 tb.
This is an example:
Intel goes to 45 nm technology, and that give a way to 8 or more core processor and upto 3 ghz per core speed without Netburst technoloy.
"Can you say there is already 8 core processor with 24 ghz total speed?"
You sad:
"It lists SDHC readers as being backwards compatible"
1-I sad about cards, not readers.
2-I sad SD 1.0 and 1.1 slots are can not use SDHC cards, I didn't sad SDHC Cardreaders can not read SD cards.
I write somethings about SDHC, because someone can buy them, this tech useless for our PDA's, i want help people. Because
I'v got so much help here,
May we can use SDHC's in nexttimes with external adapters or converters as SD.
May be...

I wasn't correcting you when I said this, I was correcting my statement that there was no compatibility. I had read at one point that there was no backwards compatibility (for legal reasons), but it looks like they changed that. but I will say that technically there aren't any 32 GB SDHC cards either. It is just a matter of what the question is asking, what is the largest capacity in development vs. what is the largest capacity possible.

Hey guys i just bought the 8GB SDHC card and the flash drive reader/writer that comes with it.
It will take about two weeks in shipping for me so i'll keep you guys inform of the type and where i bought it from.

Fast 4GB Micro SDHC

Hi,
I am sure that we would like to have the "best" accessories for our beloved HTC Kaiser.
So, what is the best 4GB Micro SDHC?
The best = The fastest and most reliable.
I found SanDisk 4GB is rated as Class 2 (2 MB/s) :
http://www.reghardware.co.uk/2007/06/12/re..._4gb_microsdhc/
And Integral 4 GB is rated as Class 4 (4 MB/s) :
http://www.lowpricememory.co.uk/Integral-4...-SD-memory.html
What is yours?
Does this classification work in real life situation? Because I am afraid that it works on a lab / test environment only.
Thanks.

I'd say the best is the Kingston 4GB: http://www.gomemory.co.uk/kingston-4gb-micro-sd-card-sd-adapter.html

the following considerations are important. remember, a chain is as strong as the weakest link and so when buying a microsd card, you have to think about how you will be using it.
0. i have named this factor "0" because i am myself not sure about the kaiser's performance when it is INTERNALLY accessing your storage card. as far as i know, the kaiser's internal access speed is nothing to write home about even with the fastest cards. i'm hoping someone else can comment and shed some light.
1. do you intend to perform heavy data transfers to/from your device/pc using:
a. activesync?
b. card reader?
if option (a), a fast card won't get to show its full speed because the usb port on the kaiser does NOT run at full USB2.0 speeds. in fact, the SLOWEST card completely saturates the activesync connection.
if option (b), a fast card will make a noticable difference. but then you have to think about the following.
2. the card will understandably be used for READ operations and performance will be important in that aspect. if WRITE speed is important to you because you will be frequently dumping data into the card, then check up the write performance of the card(s) you are considering.
3. other aspects to consider are warranty, reliability, brand name (if you are so inclined, most things, even from the best brands, are made in china any way, probably at the same factories some times )
good luck!

The higher the class the faster the card access like you say though i'm not sure on the Kaisers hardware as to wether it can access the data @ higher classes but if you can get a card with class 6 then go for it i'm using a Samsung 8GB Class 6 and hasn't let me down, all the brands you mention are reliable mind you i've got generics that work just as good on lower class's.

What is the fastest SD card the z3tc can fully use?

I have obviously bought the slowest SD made, so I want to shop something new before the marshmallow update comes (and I can make it "system memory").
5 write and 12 read is not enough. How high can the z3 go?

128 GB Sandisk SD Card
I bought one of these from Amazon back in October for £49.99:
SanDisk Ultra Android 128 GB microSDXC Memory Card plus SD Adapter up to 80 MB/s, Class 10 [Newest Version]
I did notice a bit of improvement in the transfer speed as I utilse my tablet for quite a bit of downloading with ttorrent.
I've not actually tested the data rates but I did notice that it transfers big files better than lots of little files.

With A1 SD Bench I get 18MB/sec both read and write with a card I found in my dashcam. Not convinced that it's the best I can get.
With only 16 gig onboard and Marshmallow 6 with the possibility to make the SD "internal" memory, I might want to spend a good amount to get the best possible.

Just benchmarked my card and the speeds are worse than yours - Read: 10.54MB/s Write: 8.69MB/s
Mine is the SGP612. Perhaps the bigger the slower with some of the older flash memory such as mine?

I really hope that Android 6 helps.

My card is up to 48mb/s but A1 SD Bench gives 16 read 14 write, idk if android 6 is going to improve the performance since i believe is a hardware limitation

any updates?
Wondering if anyone has updates for this topic. I just ordered a lexar - 1000x microSDXC 64GB UHS-II/U3 and hoping it will work well.
thanks.

Sorry to break it to you, but Sony chose to not support the sd card to internal storage feature.

Marshmallow doesn't help... I get around 14MB/s with an UHS I Samsung Pro.

I want to know too. In PC my card read 79 MB/s, write 22 MB/s but in this tablet it only runs at 12/4 r/w.
I had better performance in Asus K013 at 20/20 and that device was a cheapo low budget.

Samsung Evo+ 128gb or SanDisk Ultra 12gb ?

I was looking at these two memory cards online. The evo+ 128gb is around £40 and the ultra 128gb around £33. Out of the two which should I go for putting inside my s7 edge. Which one has better performance and reliability.

both are good, go with scandisk for cheaper price.

check this article
http://www.phonearena.com/news/Thes...our-Galaxy-S7-S7-edge-LG-G5-or-HTC-10_id80277
and you have this post about microsd.
http://forum.xda-developers.com/s7-edge/accessories/suggestions-microsd-t3321569
I recommend to take SanDisk Extreme Plus UHS-I U3

Don't get the Sandisk Extreme Plus 128gb. It's $200-$300 and has almost zero availability.
If you want to save money and get a fast 128GB microsd card, go with the Samsung EVO+ (i use this in my S7e).
If you want to spend $100, get the Samsung Pro+ 128gb card.
Both Samsung and Sandisk are reliable.
As far as performance of the two cards you listed....
Samsung EVO+ -- READ 82, WRITE 26
Sandisk Ultra -- READ 92, WRITE 19
Get the EVO+. Write speeds are more important than the read speeds, especially if they are higher than 70mb/sec (both are).

Correct me if I'm wrong but isn't for a phone the random write speed the more important figure vs. the sequential write speed you listed?

Personally id go with the samsung evo.

Only if you elect to use the Adoptable Storage option in Android 6.0. If not, sequential write speed would be the key field.

Whichever is cheapest at the time of purchase. You'll notice no difference once it's in the phone.

I ended up going with the 128 GB Pro + - can be had for $90. Much higher write speeds than the Evo +. The new 256 GB Evo + might match or even outclass the 128 GB Pro +, but at $250... I'll pass.

NOTE 9 sd card slot speed rating

Hello,
has anyone been able to figure what the sdcard ratings are on this?
is it UHS ii?
can anyone post their write speeds?( people with sd cards anything under UHS i/ v30 please dont bother posting)
edit:
Also, to unify results can everyone use Androbench app?
And be sure to go to settings and point your ext sd card.
thanks

ain't anyone interested/curious in how fast their transfer rate to their sd card is? gues because it has nothing to do with facebook or antisocial media then it doesn't count as being a real thing...

if you have Solid Explorer you can visually see your transfer speed.
transferring the same file across different phones / SD cards can give you a comparison.
i believe the bottleneck is the SD card, as the phone is capable of transferring at speeds far beyond what the SD card is capable of. so even if the Note 9 can transfer faster than the other phones, the SD card will limit it to a fraction of its capable speed.

check Notebookcheck.net
Also most of the phone is stuck at <100MB/s for SDcard transfer rate atm. I don't know why but, maybe to prevent heat generated.
You can get an UHS-II TypeC card reader ya know. or get 512GB for full UFS 2.1 speed.

No not really. Different files and sizes transfer at different speeds. Also, you're basically stuck with whatever speeds you get as there are very few ways to 'optimize' or 'tweak' performance of a SD card. And besides most people are still buying MP3s. Why? I don't know. Ain't anyone interested in listening to CD quality music? Myself, I still buy compact discs and rip them into FLACs and MP3s when I get it then the CD mostly collects dust.
And some of us are waiting on 512GB cards from Samsung and SanDisk to come out. No point in buying a 400GB card when I know I will get the 512 when the price comes down.

all this is fine and dandy but i was expecting actual file transfer read and write data numbers.
none provided their current rates. all other info is irrelevant.
thanks

I'd be interested to know the slot speed rating as well. Currently the phone defaults to using the internal capacity to write to for things like high-end video recording, due to the external SD not being fast enough.
...But is that actually due to the slot speed not being fast enough? Or because the vast majority of users will use standard SD Cards, which aren't fast enough to keep-up and it would cause complaints. Would be nice to find out it's the latter, I wouldn't mind investing in a faster SD Card for a little boost in performance.

Although I don't know the specifics for the Note 9. The SD card reading hardware on the device is the bottleneck and a source of where all manufactures go cheap. The read and right will top out between 60MB/s to 70 MB/s. This is why the internal storage is preferred but I the device for use and the main thing people overlook when it comes to devices with expandable memory. Expandable storage is simply meant for storage and not for high quality video recording and bust, super slow-mo, and other high quality video and image writing.

4k video takes about 100- 150Mbs on a high end camera. That's about 18 MB/sec write speed. All the medium/high quality sd cards can do those speeds...

Yes, but most cards don't reach their advertised potential and multiple simultanious writes impact speeds a lot more. This is why there are 512GB devices and why they still sell. The average person won't max out the capability of the SD slot but you always get a few that will use the device well beyond what most of us will.

I'm getting read 73.41mb/s Write 31.85mb/s with the 256gb card that came free with the note 7. Also note, I only have about 47gb free on it so that may affect the results.

I use a Samsung EVO Plus 128GB card. 68MB/s sustained read and 62MB/s sustained write, using a 28GB 4k Blu-Ray rip. The card can read 100MB/s and write 90MB/s but those speeds are only close to achievable when plugged into my USB 3 card reader.

It's rated at 100 gigawatts.

Yes, but it is a large file. Read and write speeds tend to start off a bit better and should be a bit better for smaller files.

no problem, tests are encouraging. i have the evo plus 256gb and and on the note 8 was getting barely 10 MB/s write speeds.
on the computer was getting the advertised speeds on an UHS 3 reader.

Samsung EVO+ 256GB UHS-I microSDXC U3 (exact same as aznmode above).
Using the AndroBench app:
1st Run:
Read: 76.1mb/s
Write: 31.01mb/s
2nd Run:
Read: 77.24mb/s
Write: 29.56mb/s
As a reference, the internal memory bench is:
Read: 747.8mb/s
Write: 189.0mb/s
