[Q] Does anyone else have slow SD Card speeds?

---

My RAZR's external SD card speeds are extremely poor. I get 4MB/s transfer speeds. I used my SD card on my older phone and the speeds were much better, reached upto 8MB/s on the same set of files. I tried setting the read ahead cache to 2048 but nothing changed.

Does anyone else have slow SD card speeds?

Is there any possible fix for this?

Thanks!

1) what's yous sdcard class?
2) read ahead cache, is not bigger=better, let's try other values, not just the minimum and maximum, it changes it's optimum for each memory card
3) how did you measure your speeds? on my lg dual i had for example, my class10 sdcard
12w 17r on phone with sdtools
19w 25r using it as a memory reader

A fix for this is to get higher transfer rate sd card, say 10 mb/s. But it would be more expensive.

I bought a class 10 sd card from amazon, which got a writing speed ~15m/s.

I have a class 4 SD card. So my speeds won't be great, I know that. But my card used to manage better speeds before. Is the problem with the RAZR then?

I tried 128, 1024 and 2048. There was no change in the transfer speeds. I read these speeds off teracopy's window. Is there a tool for measuring read-write speeds for the SD card?

Try SD Tools, free in market.
