solomon Posted November 30, 2006 Share Posted November 30, 2006 I looked at the "spec sheet" but it says little beyond the capacity. I *know* the capacity of my card already, I'd like to know the speed... (2GB MicroSD in this case) TIA, Richard Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 2, 2006 Corsair Employees Share Posted December 2, 2006 I am sorry but at this time we have not published the speed spec's because the performance will varry with the controller we use. Link to comment Share on other sites More sharing options...
solomon Posted December 2, 2006 Author Share Posted December 2, 2006 I am sorry but at this time we have not published the speed spec's because the performance will varry with the controller we use. That's an interesting answer in itself :) Do you mean there are multiple controllers in use within a particular capacity of MicroSD or that there are multiple controllers in use with different capacities? (Presumably the former...) Of course all of that begs the question of how we poor end users can tell what we have.... and even then I'd want to know what performance is for different versions. I'd hope they are not WILDLY different. Thanks for the response! Richard Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 4, 2006 Corsair Employees Share Posted December 4, 2006 Exactly there is more than one controller in use and they will varry in performance. I have asked for something for reference but as of now there is nothing I can tell you! Sorry! Link to comment Share on other sites More sharing options...
stev Posted December 15, 2006 Share Posted December 15, 2006 Is this the controller speed of the card reader? That I can relate to. Some computers are faster while others are slower using the card reader. It would be nice just to know of a max burst speed of the microSD cards in general without the card read limitations. Then add an note stating, "with other card readers, performace will vary." Knowing the max speed of a Dodge Viper is really cool, but the posted speed (the controller) is all you get without getting a ticket. :D: lol I'm more amazed of the size of the card to fit 1Gb or even 2Gb onto it! Peace! Stev Link to comment Share on other sites More sharing options...
solomon Posted December 15, 2006 Author Share Posted December 15, 2006 Is this the controller speed of the card reader? No, he's talking about a silicon chip on the flash module. There are two major pieces on a flash memory module - the actual flash memory chip and the flash controller chip. The flash controller "translates" the serial SD/TF protocol into read and write cycles to the flash chip. Speed of an SD/miniSD/uSD card is a function of the access and cycle times of the flash memory chip AND the abilities of the flash controller. In your analogy, the controller is the DRIVER of the Viper - it doesn't matter if you have 500HP, if the guy behind the wheel can't give the thing directions quickly enough there will be trouble. Perhaps a more accurate analogy is that the controller limits performance in much the same way tires do - no matter how many HP you have, if you can't get the power to the road you go nowhere. What the Corsair guy is saying is that they have different brands of tires - some might give you all 500HP, some might not. The problem is most module suppliers in the "value" space source multiple memories and multiple controllers - and they switch those around in their products from day to day depending on pricing. This makes it tough/impossible to spec the end module - and since guaranteed specs are part of the price adder for "performance" modules, there's even less incentive to open that can of worms in their "value" lines. Personally I still feel that they should spec some minimum (and not something pointless like "1X") and if you get a module which is faster, then more power to you! Here in uSD Corsair only offers one line, so I find the lack of specs disturbing.... Richard Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 15, 2006 Corsair Employees Share Posted December 15, 2006 Just got this from our Flash Engineer! The average will be about: Read: 10MB/s Write: 5MB/s Operating temp range: 0 – 70 degree C For the entire currant Mini SD Cards but it’s subject to change with out notice!

Thanks RAM GUY!!!! Did you mean Micro or are the numbers just for Mini? That (~30X write) seems respectable. Richard Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted December 15, 2006 Corsair Employees Share Posted December 15, 2006 No that was for Mini SD cards sorry I dont have the information for Micro but I would suspect its close to the same! Link to comment Share on other sites More sharing options...

Ok, thanks for the clarification! Can we buy a beer for the flash engineer and pry the Micro specs out of him? :D: Richard Link to comment Share on other sites More sharing options...
