How fast can ACE read an SD?

---

Who can really answer this one? What is the maximum speed ACE can read data from an SD?

For example a reading speed for a class10 SD can reach 20MB/sec. So can ACE really cope with that?

I am asking this cause I also have a class4 with maximum read speed at 13MB/sec.

So, is there a limit at how fast ACE can read data from an SD? It hasn't got a very powerful processor so is there really a need for a class10?

Do not tell me about write speed, that I know!

My SlaidMod script boost your SD write/read to make it very fast even with A2SD darktremator!!!

Yes I know man but that was not the question and...

...ooops, I posted in wrong section, Can a moderator please move this to general talk, thanks and sorry for that!

ah,for your question I think ACE read SD card with it's default speed


PS:you should move your thread to Galaxy ACE general FORUM

yes I noticed and asked for a moderator to do this cause I cannot (I think)

By the way your script rocks, it's included in ICS2 Final I believe!

NO,It isn't my build.prop tweaks that are included not script but you can install it weven if the final ICS2 has gadgetcheck turboboost

don't worry. the bus speeds between the RAM module (most likely a LPDDR1 RAM) and the CPU is much much faster than that (at least 200MB/s). The bus connecting the SD card reader and the CPU also have a good bandwidth and therefore you can be sure that whatever Class rating of your SD card is, it won't go to waste.

As a side point, do take note that Class rating of different brands are not the same in real speeds. E.g. Sandisk Class 2 is faster than Kingston Class 2.

I hope its not off topic.. But how do i know the class of my SD card?? It doesn't say anything on the package nor on the card itself?? Sorry if its a stupid question..

Nope, not stupid question no worries. Use the table as reference.



Now go to this link to test the read/write speeds of your card.H2test2 1.4.

Just take note that this app is written by a German and so take some time to slowly navigate it. Also how this thing works is that it auto generates a file and send it back and forth from your computer and the sd card. Which means that ideally you should clear your whole card so that the utility can work. However the utility can work with whatever free space your sd card has currently. Meaning only the read/write speeds of the "empty" space gets tested, not the entire card if you get what i mean.
