Hello everyone,
I am looking for someone who bought this card as well.
It is a Samsung OEM 4GB card, which is supposed to be 150x
Unfortunately all I can get from it is:
2MB/s write speed
8-9MB/s read speed
I tried 3 different memory readers to be sure I am not limited by them for some reason.
150x about 22-25MB/s is far away from what this card can perform
I’ve found some other guy doing similar tests.
http://www.thedvdforums.com/forums/showthread.php?t=455418
He’s results are very low comparing to advertised specs.
eBay seller mr. fastmemoryman is strongly stating that it is 150x and they tested it, however he does not explain how he managed to obtain that results.
He insists on sending in back as it is broken in his opinion. Doing so will make no difference as I bought from him as well 8GB version of that card. This time from USA, and not UK. After I did it I read it is not supported in Universal as it is SDHC
So 2 different cards, 3 different card readers …. Still no results even near 150x.
Btw. Can you post guys post your results. Just copy some big files to and from memory card. Preferably write to and then copy to different location as it might be cached in ram and that would false results.
I am gathering evidence to report him to ebay. They might be some cheap fakes or he might be just misleading people with specs.
Cheers to everyone from this forum, it helped me a lot in my early days of having Universal.
Transcend 4Gb 150x
Hiya,
Just wanted to say off the subject, I've just bought a Transcend 4Gb 150x and it's performing really well on my XDA Exec. Just thought if you don't have any luck with your Samsung, it's a viable alternative...
Best of luck with your tests!
Come on guys, could you please post some results from cards you bought?
I believe there is a lot of discussion about SD Cards on the Universal Accessories. Maybe others don't want to respond to a repetitive question.
I am looking for soemone with 150x Samsung OEM, which you can buy on ebay to verify my results.
I did use search button and checked few threads, but did not find any with many results.
I am just wondering which 4B SD 1.1 not 2.0 would have write speed of 5-10MB/s and not 2MB/s like the one I have.
oh dear, i also ordered an 8GB samsung 150x from fastmemoryman and like you it too is being sent from the US. How long did delivery take for your card? Soon as I receive mine, i will post some results as vista does show the actual transfer rate from PC > SD Card.
Ordered 21st of Jan and got it yesterday much more than 15 days.
8GB is about 4MB/s write speed and 4GB is 2MB/s .... but not 15 like advertised hehe.
4GB SD OEM from Fastmemoryman not 150X
I've had exact te same experience (same card from Ebay, same - slower - speed and same reaction from mr 'Fast'memoryman), and decided to let it be. At the time I bought it, it was cheap and I can live with this speed.

Hi there,
Bro has just picked up an Xda Orbit and I wanted to know if there are any high speed Micro SD cards at 1GB or 2GB available?
Since my Xda2i days, I've been impressed with the Transcend range but they dont seem to do any hi speed micro sd cards - or at least I can't see them listed !
I'm open to other's Sandisk etc but I'd like them to be hi speed cards
Can anyone point me to sites which have them please?!
Cheers!

Right hand side 2gb £49.99 +postage, I bought one just before Christmas all cool.
But note the thread on MicroSD issues on the Artemis/Orbit in other thread - issues with the PDA not SD card.
http://forum.xda-developers.com/showthread.php?t=285511
i can only recommend the card mentioned by ricardoC above. have been using it for about twelve weeks now and had no issue with it at all. you should keep in mind though, that afaik,the speed of a card INSIDE a ppc device is purely dependant on the speed of the device. therefore the stated read and write speeds not applicable. nevertheless i FIND the card to perform faster in my hero in comparison to sd cards inside my mdac one.

got mine here: http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=270057565199
SanDisk memory products have never given me any problems, plus there is 5 year warranty here in Switzerland.
I used a "standard" SD in my old BlueAngel and when I changed it for an UltraII Sandisk SD TomTom map access/scrolling was a LOT faster. Its true the card is only as fast as the interface but you want to get the max out of it so fastest card you can get is best.

It might be true on a Blue Angel but the standard SanDisk SD card is more than fast enough for the Magicians SD interface so buying an Ultra version is just a waste of money.
Disregard my reply, I thought I was still in the Magician forum.
It might be true for the Artemis though.

high speed micro sd card - update
Hiya
I ordered a 1GB Sandisk Ultra 2 card for my bro's orbit and hopefully it'll work without hiccups and possible corruptions!
My bro's Orbit will be my little test unit and if all is well, I'll get one too ! and the same micro SD card of course!
thanks for the pointers
Cheers, Dennis! West London UK!
Depending on what you want it for note that TomTom's single map of western europe is 900mb - so it will nearly fill a 1gb card, just thought I would mention it.
I use transcend never have any problem with P800w or Artemis
i'm using this brand since Dopod 818Pro or XDA NEO
I´ve done a Benchmark with the MicroSD Cards I had available.
Please find the results attached.
Bought the 8GB SDHC Card at the same place as Snake28:

I made all required steps, I registered, waited for activation.
Still not able to view your benchmark.
I have to buy a microSD card. I am looking for 2 GB.
I use to look arround and buy best performance components, but now I was not able to find my way.
I would be grateful if you would supply me the results.

Hi mboxmbox,
I just send an e-mail to the adress you provided with the Benchmarkresults attached as a pdf File.
Sorry that the provided zip File above was not accessible for you.

I got the requested file
I would like to thank you for your very quick response, for your help.
It is strange that manufacturers do not provide enough info regarding this type of card, while for other cards there are available full specifications : CF cards are much better documented, as you know. I think that the number of devices using smaller size cards will grow, this is a natural tendency.
I just recently bought a device that is able to use microSD card and I use to carefully look around and read others experience ; vendors tend to say only part of the truth. I want to use the card not only “inside” of the device, but also to carry data and feed it to several PCs, so speed of the card might be important.
m.
Im glad that I could help you.
But - as you see I did not measure the MicroSd Cards performance when connected to a USB 2.0 Port at the PC. As far as I know, the Artemis Device is just capable of USB 1.0 to read/write to the internal MicroSD Card. So it can be expected that performance will rise significantly when connected to a USB 2.0 capable PC.

Great results.. Could you hook me up with SKTools? I'm receiving my 8Gb card tomorrow or Saturday and I would like to benchmark it and post the results for you to compare.
You will find the Software here:
http://www.s-k-tools.com/
Its not free, but you can use it for a period of time. Which should be enough to do some Benchmarking.

USB 1.1 is 12 MBit/s
Does your benchmark is MByte/s ?
2 gb micro sd card
dear all,
im using HTC touch, right now im using 1 GB micro Sd card, i want upgrade it to 2GB. my htc touch will compatible for 2GB card? it will work smoothly or it will hang?
pls suggest me.........
Have just acquired a Touch Pro 2 on eBay, and am now thinking about getting an SD card for it. I assume the TP2 supports SDHC...?
I can get a 16GB class 2 card for about £30, or a 16GB class 6 card for £50. Am I likely to notice much actual difference in speed between the two when used with a TP2?
Depends.
In day to day usage of the TP2, no I don't really think so. You're not going to be able to take pictures any faster (the camera isn't capable of fast shooting), movies will run fine from a slow card. Maybe searching through your email would be a bit faster, if you have a lot, but I can't imagine it will be significant.
Where you would see a difference is if you take your SDHC card out of the TP2 and put it into a PC for dumping lots of data on it at once - for example, copying over lots of MP3s or movies. If you're transferring multiple GBs at a time direct from a PC, you will notice a worthwile % increase with the faster cards.
So if you do that regularly it might be worth it. If you tend to change the data on the card only infrequently, then I doubt it is.
Personally I will be getting a slow card. I only have a fast card SD card for my Digital SLR camera, where the faster card enables more shots to be taken per second.
whatever you do do not get a Transcend class6 16Gb card. They are not compatible. I know there's a thread listing card compatibility in the rhodium forum, but I couldn't find it now.

Wow, thanks for the warning, that was exactly what I was thinking of getting.
firstly i beleive the class relates to write and not read speed.
second do not buy a card off ebay whatever you do.
i have come accross an a-data 16gb class 6 in my searches. in the end i got 8gb class 4 from play for a tenner delivered. may get a 16gb if i ever hit the limit. by then the price will have dropped to reasonable level.
i had a 2gb in my xperia and never filled it. i have a ipod touch for music and a netbook.

all the cards i have ever bought off ebay have been fakes.
some have worked but been slow. others have corrupt sectors. some have failed all together. thankfully last time pay pal refunded me.
look at www.sosfakeflash.wordpress.com/
buy the card if you want. that site has programs you can test it with to determine if its legit. i will never buy a memory card from ebay again.
Class only deals with write speeds, not read speeds BUT if the card has a higher write speed, it will normally have a higher read speed as well. (Though it's not a set rule).
Thx for the heads up. I think i'm going to risk it anyways. This seller has been on there since 2000 and has sold a ridiculous amount of flash memory ~20,000. I would hope the system would show some signs of fakery over that span of time.
I will try the tool you linked once it arrives tho.
Thx again
PS here is the ebay item # if you want to look: 380143609813
I decided I didn't really need 16GB of storage anyway, and ordered an 8GB class 6 card - a SanDisk Ultra. Got it from these guys on Amazon UK Marketplace.
They have a pretty high turn-over - nearly 30,000 ratings in the past year. I also used this tool to check whether the card was genuine or counterfeit. It passed with flying colours (no errors at all) so I think it's probably the real deal.
A quick, informal test (copying a 700MB file onto the card) suggested it was writing at about 12.5MB/s when the card was connected directly to the PC's USB port, and about 5.5 MB/s when accessed via the phone (in disk-drive mode). That suggests that the phone might get some benefit from a class 6 card, although it's hard to be sure. Certainly this a is a VERY fast card when removed from the phone and connected straight to the PC. (In fact the testing software rated it even higher - 14.9MB/s write, and 17.5MB/s read).
No reliability problems of the sort associated with the Trascend cards (although I'm not sure that affects 8GB cards anyway).
Trancend 16GB Class 6
I currently have a Trancend 16GB Class 6 and it works just fine.
I only buy cards from Sandisk and usually from amazon. EBay has a lot of fakes on it! I have a 16GB Class 2 from amazon that I picked up for $40. Speed test while in Disk Drive mode through the phone show a Write speed of 3.8MB/s and 6.4MB/s read speed. I have 10GB filled so far and It didn't really take that long to do. I'd say if you were filling the card up with 10GB of new music a day then yeah those speed suck but for a few big loads just to get it started no big deal to me.
I can stream a 800x480 AVC ~1.2Mbit off the card with no hiccups. So I'm not worrie about the speed considering anything more then that the processor becomes the bottleneck not the card.

Do you use your tp2 for music?
try playing a few songs in a row from the music tab with screen turned off...
I just recieved an A-Data 16GB Class 6 from ebay. Seems to be fine, passed memory test with no errors @ 8.9MB/S write and 15.1MB/sec read.
Worth the money just copying video and music files to the drive via pc. Way faster than my previous 8GB Class 2. Don't notice any real difference in the phone tho.

I had a Transcend 16Gb class6 that disconnected if I tried that. I had to reboot to get the card to register in the Phone.
Been out on the road for work all week using music over bluetooth and co-pilot 8 heavily. Working like a charm.....maybe i just got lucky.
I'm putting my $0.02 on the table on MicroSDHC cards. Basically for those of you that want faster data transfer on a larger card like an 8GB or 16GB MicroSDHC, it can make a difference but beware of brands that are not well known and their transfer speeds. The Class ratings on the MicroSDHC cards only apply to their guaranteed throughput rates and are NOT indicative of the actual speed experienced on the cards. I've seen some Class 2 Sandisk cards outperform Class 6 A-Data cards before which is a little scary.
I hope I posted this in the right section, I wasn't sure where a question about MicroSDHC cards would go here.
By the way, I live in the US.
I have been Googling this for days now, and coulden't find any conclusive information, especially since most of it was from random tech blogs and not respected tech/research sites.
I am looking to buy two MicroSDHC cards to use in a Photofast CR-5400 ( http://www.amazon.com/PhotoFast-CR-5400-MicroSD-Adapter-Dual/dp/B001I0T92Q ), speed and performance are pretty important as I will he handling a lot of data through it.
First of all before I start, anybody familiar with this adapter? Where would be the best place to purchase one so I don't wind up with a Hong-Kong bootleg? Ive had trouble purchasing flash memory online before from places like Amazon or Ebay where the memory was a bootleg that didn't perform anything like the real thing.
Now, I know that Memory Stick Pro DUO devices are generally faster than SD or SDHC devices, but AFAIK that device sets them up in a RAID 0 configuration so I am hoping that will help, this is why im trying to get the best performance MicroSDHC cards I can afford. And trying to get reliable information on these things has been a lesson in confusion.
First of all, it almost seems like the class speeds don't matter. Ive seen benchmarks that showed class 4 or class 2 cards outperform a class 6. Whats the point of these classes if they are so meaningless? How can a class 2 device have faster write speeds than a class 6? And is this classification only for writing or reading too? Why are the "ultra" models of some cards, which are supposed to be very high speed, listed as class 4?
Second, I heard that there are other variables that usually are not listed anywhere, such as Random Access Times, which from what I read are internal processes taking place in the card itself rather than having anything to do with the card reading/writing to whatever it is plugged into. And I really have no idea what else could be a factor.
I was looking at THIS Transcend card ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820208475 ) mainly because the previous 8GB version ( http://www.newegg.com/Product/Product.aspx?Item=N82E16820208453 ) seems to be the best one you can possibly get, the 8GB model is class 6, rated as very high speed, and even has a low Random Access Time. But that doesn't mean that just because the previous model was good, the next one will be of the same quality, and on top of that I don't know if it'll even matter in that Photofast adapter or not. Not to mention its kinda pricey, don't forget that I will need to buy two as well as the adapter (though since the 16GB Memory Sticks came out at over $200 and they are barely around $100 now, and the 32GB still isn't out yet, I am going to assume it will still be at least $50 cheaper than just buying a 32GB Memory Stick............ when they come out).
So what would you recommend I do? Where can I find information that makes sense of this? Where can I find good benchmarks/testing done on these cards that on top of speed measures the other factors as well? Where would be the best place in the US, retail or online, to purchase such a 16GB MicroSDHC card for the best price?
Thank you for your time.
what are you using the Memory card for? (what application, video/photo taking, loading applications...)
Class X just says the minimum write speeds on an empty(defragmented) card... 2 means 2MB/s write, 4 means 4MB/s etc...
some SDHC cards also come with another rating... 133x that says max 20MB/s speed, depending on the manufacturer, that may be write or read speed
best place to buy is directly from Newegg/Tigerdirect, or from Amazon fulfilled by Amazon itself or a reputable merchant

Patriot 8gb class 4- very slow from pc to card ???
Anyone having any current luck with Patriot 8GB Class 4 micro sd's?
I copied everything from my PNY 2GB to my netbook. Very quick as expected...
Formatted the Patriot FAT32. Tried to copy back to the 8GB from the netbook and it was painfully slow. So slow it is not usable.
Both pc and Tilt recognizes the Patriot as 8gb.
Anyone having similar problems or any suggestions?
Possible formatting issue... No more Patriot SDHC.
I think I got it...
Took about 12-15 minutes to copy back to card.
It appears to be a formatting problem with the XP fomatting.
Used this... http://www.sdcard.org/consumers/formatter/
Tried the Wife's new HP laptop (school issued) last night and had the same problem. That pointed me to a possible card issue.
Moral of the story- google is your friend.
Just to be safe, I would stay away from Patriot's 8GB C4 cards.
I would just try another brand of microsd card. Sandisk are reputable but usually the most expensive, though on amazon 8gb cards can be had for less than 20 bucks. Kingston is another good brand.
I decided to order from Amazon the card. Is it better to Kingston microSDHC 32Gb Class 10 or Samsung 32GB Class 10 Micro SDHC Extreme Speed Card? nowhere to be found a benchmark, I saw a mention on the forums, such as that Kingston is quickly. any ideas?
what? no one? no one has good card?
I don't really think it matters, not to me anyway.
That said, have a look at this thread: http://forum.xda-developers.com/showthread.php?t=1150369
i saw it, it wasn't helpfull...
I would suggest going with the kingston one myself, never had any problems with them in any of the phones I owned.
Might want to browse newegg for sdcards and look at the feedback people leave for sdcards there, a lot of people post their benchmarks on their phones there.
