anyone know a good app where i can test my sd card speeds?
thanks
This is the best one there is:
SDTools

Hi,
I'm just wondering if it would be possible to boot our ROM from sd card, so that we had more RAM and internal memory free? I'm not talking about dualboot.
I too was wondering about this!
I read somewhere that this was possible on the Xperia X10 mini, as far as I remember, at least a Class 6 microSDHC card was required else the booting will be very slow!
Doesn't anyone here have an idea on this?
There was an experimental data to sd that did this when we were using 2.2 rooms, but it was never very stable. I think the only advantage was to boost quadrant scores, apart from that you can do almost the exact a few thing with link 2 sd

whyy bother when we have so super-cool RAM. besides its wasting SD-card space.
Looking for people who have benchmarked their sd cards.
I have a fairly old 32gb generic sd card, it doesn't even have a speed rating on it.
I want to use bootmanager but I'm not sure this old card is fast enough to boot off of. I'm testing with SD tools on my tbolt
I get about 6 mb/s write speed
I get about 7-9 mb/s read speed in SD tools,
I know class 10 cards can vary wildly in performance and quailty
I am wondering if anyone has recommendations for the best quality card
with the highest read/write speeds, I want to get a new card but I don't want to pay a lot of money for a card that is only marginally better than mine.
i just downloaded that program to help you out,
got
7.0 read speed (peak was 8.6)
17.6 write speed
I am a long time user for boot manager and havent had any lag issues with this sd card
sd card is
32 gb
sandisk
class 4
came with my tbolt
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!
Code:
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.

Previously, I tried to use an Adata class 10 32GB micro SD and mounts2sd to work around the small data partition problem.
It might be the slowness of that card (pasted the benchmark by Crystaldiskmark), my Evo 3D starts to lag that I have to move the application data back to the data partition of the phone's eMMC. The read write speed using A1 SD Tool is 19.33MB/s and 10.19MB/s.
I bought another Sandisk Ultra 64GB micro SD and benchmarked it using Crystaldiskmark and A1 SD Tool. The read speed using Crystaldiskmark is above 40MB/s, but the read speed tested using A1 SD Tool is 20.50MB/s. The write speed tested using A1 SD Tools is 9.17MB/s, which is even lower than the original card.
I would like to get a micro SD, maybe even a Sandisk Extreme Plus, but I am afraid that there is an IO limit on the micro SD card slot, which is a hardware limitation.
Any pointers? Thanks!
Does anybody know if this tablet actuaklly supports UHS-1, while mean that it uses the UHS bus and thus cann write/read with this speeds?
I do not ask if such sd cards work in the tablet, which they do. i want to know if the tablet can use the full performance potential.
I did a speed test with a benchmark app and it seems it doesn't support the full speed of my uhs-1.....
I should try with other test apps
