Memory Card Benchmarks 2gb v 16gb

---

All,

Just thought i'd let you know the benchmarks I got from the exisiting 2gb card and a new 16gb card I've bought.

The card I've bought is the new Sandisk Class 4 Ultra micro sdhc which cost me £50 from Amazon.co.uk. I was a bit sceptical at first as the 2gb seemed quite fast so wondered what class it was as it doesn't say and I didn't want the new card to be slower. But I went ahead and bought it anyway as i needed the space.

Both cards are formatted to fat32 with 4096 of allocation

So, CrystalDiskMark benchmarks...
100mb file, 3 passes...

100mb file		Sandisk 2gb		Sandisk 16gb
			Read	Write		Read	Write

Sequential		10.67	6.639		19.93	16.57

Random Write 512k	10.55	1.261		19.52	2.634

Random Write 4k		2.822	0.010		3.984	0.026

Speeds are in MB/s

Quite a bit faster than I was expecting, so quite happy about this. I know there will be some hardware limitations in the phone so it can only read / write at certain speeds, but for taking pictures, it can save the images quicker and thats a plus for me. Plus the reading of data in music player etc...

Hope it helps some people

quite an impressive hike in write speeds.


I did wonder about the transcend class 6 they have for £55 but then I realised it said 2-3 months expected delivery !

In the end I bought the PNY 16gb card from play for £26 it's supposed to be a class 4 I'll benchmark it when it arrives.

quite impressive
congrats mate for the new card

However, i guess it makes more sense if the larger card volume was a bit slower!

Anywayz, doesnt the bigger card have any negative effect on the battery in terms of consuming more power to mount the storage volume?

Interesting - I have a 16Gb Class 6 on it's way - should be here next week. I'll try and run the benchmarks for it and see if there is much difference.

would be nice if someone could try the class 2 sandisk 16 gb

how did you do the benchmark?

PNY card class 4 - where from?

I too have a class 6 16GB card on it's way and I will post my bench's as soon as it gets...

I won't buy a higher one than my 8GB one till a 32GB is released -.-
