Dumb questions about expandable storage

Should any micro sd card work or do you need a special one from motorola? 2gb is not enough for me.

P.S. really loving the phone so far, but VM's 3g speeds suck :(.

Any will work, just make sure you get it from a reputable source. There are a good number of SD and uSD cards being sold that are 1 or 2gb but hacked to display 16 or 32gb.

I use Sandisk personally.

It was $50, only a couple bucks less than the ones from Newegg. I highly doubt you're going to get a reliable 32gb uSD for too much less than that right now. 16gb is another story. I just got one for right around $20 on sale.

Might be legit IF he makes sure that it is NOT selling from China. All the bogus card reports I'd read about were from cards purchased in or from China from bogus sellers.

Sandisk & Kingston are just re-badgers...

Name an electronic device that isn't anymore. If you buy a Kingston or Sandisk from Newegg, Newegg and/or Kingston/Sandisk is going to make good if you get a 32gb that holds only 2gb. A seller on ebay otoh, I highly doubt will. Whether he is in the US or China.

Reputable companies stand behind their product.

Toshiba, A-Data(IIRC), and a few others from Taiwan and Korea that I don't recall the brand names of any longer. Any "Made in Japan" card is really a Toshiba card as they have the only plant in Japan... Usually the highest quality cards too, followed by Taiwan with China anchoring the bottom.

Easiest way to tell is to look at where the item ships from...

First I've heard of class 10 data corruption. How come it'll corrupt a phone's data and not a camera's data?

The card data is what's corrupted. If a class 10 card is used a error will popup saying the sd card is damaged.

The class number is the cards write speed. Most phones have a max write speed of about 6-8 MB/s. Class 10 is made for 10+ MB/s speed, if the phone speed is slower data corruption happens.

Cameras can push 10+ speeds so a class 10 works very well with them.

I have a Class 10 32GB card I use as a thumb drive for watching movies on my work computer.

So the short answer is don't buy a class 10 32 gb sdhc for use with the Motorola Triumph otherwise you will get data corruption errors? I've been shopping around for a class 10 since I've heard it is a noticeable improvement in data transfer speeds/performance . But what's the point if class 10 doesn't work for this phone?

Do you have any articles or forum discussions about this? I've searched (this is the 3rd thing that pops up for me on google when searching the matter) and come up empty handed.

I would find this very hard to believe. If the card is FASTER than the phone is capable of supporting (R/W speeds), one would think the card is being merely under-utilized. However, the faster card should support a slower-speed system.

Faster transfer speeds? For what putting content on or off the card to a PC? I hardly believe you'd notice any difference with a Class 4, 6 or 10card when using the USB connection, or FTP. I could be mistaken of course.

I would expect if you had a very high-end digital camera, you'd want the fastest speed possible such that the system is ready to shoot and save another image. I would think, phones are just not that fast.

Contact Motorola Customer Support.
 
According to a Motorola representative, any class SD will work. Asking the SD card manufacturer to make sure Class 10 works on Motorola phones would be better though.

32GB MicroSDHC Class 10 $55 ($45 for new customers) @ Newegg.com
I've been tracking these things for over a month now, and it's finally back in stock.

Just as a heads up, the reviews all say that these cards are on the low end of Class 10. Mostly ~ 10MB/s write 15MB/s read.

New customers (or new accounts) save $10 by using promo code: NEWCUSTOMER10

Might not even apply to the MT as it's not even a Motorola design, just a Motorola branded Foxconn ODM phone.

It's probably more likely a possible OMAP3 SD interface problem maybe? Or whatever changes Motorola made to Android on their inhouse designed phones... (MT is pretty definitely based of Foxconn fw given all of the log labels, hope that Motorola/VMUSA coughed up for further support... specifically OS version upgrades...)
 
My Samsung Intercept was the one giving me errors using class 10 and Virgin Mobile support gave me that info but..... It's looking like this Motorola Triumph can handle a Class 10 without errors. :)

Right now, I'm using ADATA 32GB Micro SDHC (Class 10) $69.99 without any problems and running full speed.
