So I picked up a 1GB Kingston card from Fry's for cheap, fine and dandy, but I didn't really think about R/W speed. If I'm the type to OC my 8125 to make it snappier, am I going to want to look into getting a 1GB that's got faster throughput? I've got all my startup apps residing on the phone, so maybe I won't really notice a difference anyway?

Hi all,
I need your opinion. I'm planning to buy a Sandisk 512MB SD Card. How much does it compare with the 256SD Card with regards to speed? Is reading/writing much slower because of its bigger size? BTW my device is XDA. Thanks
My understanding of speed diffs
I don't think 256 vs 512 will make speed differences. The speed differences come between specific cards. My brief research yesterday suggested to me that SanDisk are kinda slow, even the Ultra II cards. It seems the fastest card, consistently, is the Panasonic. I have a plain 256MB sandisk card it PocketMechanic benchmarks it at 0.7x. I will test my new Panasonic card when it arrives later today (hopefully!).
Just for comparison, Lexar 32x cards are rated at 4.8MB/s, the Panasonic is supposedly rated at 10MB/s.
Another data point, I saw a discussion on Amazon.com reviews about the SanDisk 512 and somebody stating it was faster than the 256.
All this leads to: you really need to benchmark the specific cards you are interested in to see if they meet your speed needs. Speed is really variable, people talking about a single process that takes 45 minutes on one card and just like 1 minute on another card (brand).
Got the panasonic card
I got the panasonic card. It writes at "2.9x" as opposed to "0.7x" I got with the stock sandisk. That is better than 4 times the speed. Benchmarked using Pocket Mechanic on an XDA.
I'm familiar with the difference between the class 4 (4MB/s transfer speed) and the class 6 (6MB/s transfer speed). But is there any value in using a class 6 card on the XV6800 (regardless of size)?
I ask because I have a 4GB class 6 A-Data microSDHC card in my XV6800 right now and there is no problem at all with it. However, I am considering purchasing an 8GB class 4 Sandisk microSDHC card. So it got me thinking, even thought the A-Data card is capable of a faster transfer speed, that doesn't mean the XV6800 is ever actually using that extra speed. So would I see any slowdown if I moved to a "slower" spec'd microsdhc card?
I looked around for transfer speeds on the XV6800's microSD card slot and didn't come across anything.
Anyway have any data on this? Thanks in advance.
Depends some on what you are using it for but I doubt you will notice much of a difference. When transferring using a card and a card reader from your computer you may notice a difference but otherwise the interface in the phone itself doesn't seem to be all that fast anyway.
Don't get me wrong, I appreciate the comment, but that's why I'm asking if anyone has any actual data. The device either reads and writes to the microsd card slot above 4MB/s or it does not. I have not found a way to benchmark it so I'm looking for some actual detail. But thank you.
So I found an application that is supposed to measure the transfer speeds of the card slot on a Windows Mobile device. It's from Audacity Audio. The link on Softpedia is here.
I'm familiar with the application because I used the Palm OS version on my old Treo 700P. The problem is that he results always seem inconsistent and confusing.
In any event, I ran the test on two different microSD cards. The first is an empty 1GB Sandisk microSD card with. These cards don't have a "class" rating. The second is a 4GB AData Class 6 microSDHC card. I still had 2.5GB of the 4GB empty.

Honestly, the scores don't seem to make much sense. The read speeds all indicate north of 4MB/s and most of the time above 6MB/s. That's good. But the write speeds seem pointless. 330KB/s (.3MB/s) for the 1GB and 110KB/s (.1MB/s) for the 4GB ?!?!?! That doesn't seem right.
Anyway, any ideas would be welcome.
Write speeds are typically going to be a great deal slower for flash memory. And larger cards being even slower for writing makes a twisted sort of sense. All flash cards have "load-leveling" algorithms built into them to spread the writes across the flash disk in order to reuse locations as little as possible (flash memory cells have a limited lifetime). So the bigger the card, the more memory the load leveler has to manage. Of course, I could have it completely wrong....
Hi all,
For android on TP2 (rhodium 400 for my case), would it be worth upgrading to a 4GB SDHC to run the android files?
Would it be noticeably faster?
I see 4GB microSDHC goin for about $8 on Amazon, and I might go for one if it makes any difference in android performance. Anybody's opinions?
Currently I have 2GB (I think class 1).
Thanks in advance.

If it's not an SDHC (or better) card it's technically "classless". At any rate, I doubt seriously that you'd see any better performance on it. I have a 2gb "classless" card and an 8gb class4 card, and honestly Android runs about the same on either card...

most of the 2gb cards are pretty good in speed, name-brand manufacturers didn't have to put a class on it - i get around 19mb/s read, 10mb/s write on my sandisk 2gb.
anything more - 4gb/8gb/16gb/32gb have classes because they had to do some tweaking for the sdhc specifications, with classes meaning minimum sequential write (C2, C4, C6, C10 = minimum 2mb-4mb-6mb-10mb/s sequential write). obviously, there are some cards that could perform faster than their minimum write speed (my sandisk 32gb C2 does 5.5mb/s write, and my a-data 16gb C4 does 9mb/s write)
just don't get a crappy generic
Mine must be classless. I am not exactly sure how fast my 2gb is, but it's at a decent speed. When I transfer about 200 mb files, it takes me about a minute roughly. I will just stick to my 2gb then.
Saves me $8 bucks! Thanks to both.
Hi just wondering if anyone would know if we can upgrade our ram? i spoke to a online dell person they said no. but then im thinking did they say no cause it makes the phone void or cause its not possible. they told me the ram is sdram and i was thinking if you got 1gb or 2gb of sdram running at the same mhz would it work? also upgrading internal memory? give it a class 10 32gb upgrade?
I would imagine the ram is surface mount, so if you wanna take your phone apart and solder in new team, go for it.

Internal SD upgrade
I dont know if I would go as far as trying to upgrade the RAM, but I did replace the 2GB internal microsd chip with a 4GB class 10 microsdhc chip with no bumps and I can certainly tell the difference.... Boot up is several seconds faster and anything that requires accessing the card is much snappier....
Cant remember the link, but you can do a search on Google for changing the Streaks internal SD and it will take you to a thread over at modaco with a full take the phone apart route and a "cut a piece out" as I call it route.... I cut the small piece out (very carefully, so carefully I was able to glue it back in and can barely tell it was touched)
Eventually I'm going to have to take mine apart to replace the glass. At that point I'm going to upgrade the memory. I saw that article too. The general consensus seems to be that if you go with high grade high speed memory it is worth it. I just couldn't be bothered until it needs to come apart anyway.
yh i thought upgrading internal sd with something big and speedy would def benefit for games and stuff to store on phone. but would def love to have a gb or 2 of ram. who needs duel core if you got decent ram for it. i personally think duel cores are only good for big multi tasking otherwise a single core with high ram would be faster or the same
While looking over some antutu benchmarks posted for both phones I couldn't help noticing the substancialy higher write speeds of the One X. I was juist wondering if the 32/64GB S3 versions might also have faster internal SD. Does size matter like it does for pc-based SSD's performancewise? With the faster CPU, slower writes might become noticable I think. That said the S3 will probably be my best phone
