Explanation of microSD card classes and speeds

[dcreed]

I keep seeing people misunderstanding what the class rankings of microSD cards are and mean. And, unfortunately, there's no independent rating authority to guarantee that some company claiming to have a Class 6 card really is a Class 6 card. So if people want to chime in with their real-world measurements of cards, that'd be great.

First of all, Mb means Megabits or millions of bits, MB means Megabytes or millions of bytes -- 8 bits in a byte. Computer Science 101, folks. So pay attention when your cable provider uses an upper-case or lower-case "b" in their advertising.

Class 2: read/write at 16Mbits/second (~1.9 MB/second).
Class 4: read/write 32 Mbits/second (~3.9 MB/sec).
Class 6: read/write 48Mbits/second (~5.7 MB/sec).
Class 10: read/write 160 Mbits/second (~19 MB/sec).

win32diskImager, which you'll probably be using to write an image to a microSD card, will give you a basic rating of how fast it's writing to your card...or reading from it when you make a backup -- and I recommend backup images so you don't have to start completely over sometime. I'm sure others will recommend other things like Sandra for measuring speed, and they're probably more accurate.

Your card-reader is probably hooked up to a USB 2.0 bus on your motherboard, and that's 480 Mbits/second, so don't try to blame that as the bottleneck; unless you're running USB 1.0 which is only 12 Mbits/second.

Just thought you'd like to know.

Real world experiences would be appreciated! Especially if they include brand, model number of the card, and where purchased from.

I just used CrystalDiskMark 3.01 to do my bencharking. Did 50MB read/writes, 5 iterations.

An ADATA 8GB "Class 6" microSD card (from MicroCenter):
Sequential Read: 18.25 MB/s (~Class 10)
Sequential Write: 5.46 MB/s (~Class 6)
512KB Random Read: 18.29 MB/s (~Class 10)
512KB Random Write: 0.98 MB/s (~Class Kaka)
4KB Random Read: 4.06 MB/s (~Class 4)
4KB Random Write: 0.01 MB/s (~Class Sewage)

By comparison, an Extreme III ("Class 6") SanDisk SD card I use for my 15Mp camera:
Sequential Read: 19.99 MB/s (~Class 10)
Sequential Write: 19.01 MB/s (~Class 10)
512KB Random Read: 19.71 MB/s (~Class 10)
512KB Random Write: 3.65 MB/s (~Class 4)
4KB Random Read: 3.52 MB/s (~Class 4)
4KB Random Write: 0.04 MB/s (~Class Bupkiss)

So your Sandisk Class 2 outgunned the Adata Class 6. Nice. It was the only card I could find around here for a decent price, but I guess I got what I paid for. Now off to NewEgg....

 

[Mark_Venture]

One thing to note.. my cards were BLANK and formatted as Fat32 if that makes any difference.

[crspy]

I believe the 4k is what affects performance the most. It's similar to access time correct? (it's slower but it's the "real" world access time) Also everyone should benchmark the cards specifically on the nook color, so we know the physical limitations of the device and buy a card accordingly. Just some thoughts

 

[surfmly29]

Here is a Transcend 16GB Class 6. Heard some good things about this card (and just could not find a SanDisk this size and class):

I'll try and post again with times from running it on my NOOK, once I get things running on it.

NOTE: I tried a cheaper Patriot 16GB Class 4 first (from local Frys) and it had such low marks I didn't even take the time to copy the test details, I just returned it on the spot.

Re-posting the definitions so folks don't have to refer back to page 1 of this thread all the time.

Class 2: read/write at 16Mbits/second (~1.9 MB/second).
Class 4: read/write 32 Mbits/second (~3.9 MB/sec).
Class 6: read/write 48Mbits/second (~5.7 MB/sec).
Class 10: read/write 160 Mbits/second (~19 MB/sec).
