Default What microSD speed for Curve?

Please Login to Remove!

I'm thinking of getting an 8GB microSD card for the Curve. I've found out that there are Class 2, Class 4 and Class 6 cards available, with the class rating relating to the read/write speed.

I'd like to get the best performance possible, but I don't want to spend the extra money for a faster card if it doesn't make any performance difference. Does anyone know what the fastest class rating is that the Curve is able to take advantage of?

For unequal speed ratings I guess that the system (i.e. phone + memory card combination) will operate no faster than the *slowest* of the 2 components.

Regardless of that, I own a Class 4, 8 GB Kingston microSD card and it works as expected in my Curve 8320.

I found one in eBay: NEW KINGSTON 8GB MICRO SD SDHC MICROSD MEMORY CARD 8 GB - eBay (item 250313120724 end time Nov-21-08 09:59:08 PST)

Default micro sd speed

I have never tested it. When I bought the 4 gig card on newegg a few months ago it was very cheap and rated very fast. it is a hdsd card. As far as I can tell there is no lag what so ever when accessing or recording data on the card.
$ gig seems to be enough as I have a little over one gig free all the time. Glad to know that 8 gig cards are out there...
I am also happy that the card I have will work in the new phones rim is producing.

I've been searching the forums for the same thing, and so far I don't see an answer to the question. RIM's no help either.

Answer is in the above post:

Quote:
Class 2: 2 MB/s
Class 4: 4 MB/s
Class 6: 6 MB/s
The Class only refers to transfer speeds.

MB/s means Megabytes per second; a measurement of transfer speed...

I understand classifications for the microSD

but what i'm actially asking is how fast the blackberry writes and reads the card
in otherwords, what's the transfer speed of the Curve (8320/8330)?

What's the class for the Curve???

There is no transfer class for the Curve, afaik. The speed of the device might be affected by the amount of memory available.

ok, I'm guessing that's internal memory.

thanks for the input.

I'd consider class 2 kind of slow... They have quite a few class 6'es out there. (But 4GB for 10 bucks not bad.)

Newegg just had 4gig class 6 for $6. I got 2, couldn't pass up the deal. Check slickdeals.net. They are on sale all the time. I cant wait for a 16gig for around $10!

What do you all mean slow? There is no noticeable difference between classes unless you use the media card in a fast motion digital camera. What you need is to get a name brand quality multi-wipe media card from a reputable manufacturer and retailer. A BlackBerry does not access the the card for anything that requires faster speeds. Even the video function is relatively slow. However, cell phones users do tend to add and subtract data from media cards often.

+1

the berry reads our card so slow it doesent matter. it reads maybe a meg a second. For instance i have a 8gb class 4 card. i transfered a 350 mb movie to the card while hooked up via blackberry and it took like 9 or 10 minutes then i used a card reader and took less than 3 minutes.
