Are the read/write speeds on this the same as on the 32gb version?

I copy a couple hundred 10 second video surveillance files to the Leaf daily. I don't know about the 32gb unit, but this little 16gb does the job in seconds, a bit faster than the 1TB hard drive in my Mac. I have displayed the videos without much (if any) noticeable latency. I would suspect the transfer speeds are equivalent. I don't have any documented evidence of my assertion.

Is it normal, ya sort of :) Not real world results, but it gives you a number for comparison between other devices. Its sort of like car performance and fuel economy results, they are test track and not real world results if that makes any sense. 32gb is the unformatted size, so figure a loss on average of about 74 megabytes (MB) per GB for formatting, basically 32 x 74mb, is about 2.368 gigs, and 2.368 subtracted from 32 = 29.632 but close enough to your 29.71GB number. It may vary slightly on different devices like sticks, drives, etc, depending on what they need for overhead. As far as the speed tests, that really depends on the type of file you are reading or writing. Tiny files in short bursts will give you a different result than reading or writing a 5 or 10gb file. I think the stated 40 mb/s speed is an average of whatever mixture they test on these devices. The chances of hitting that speed is probably not going to happen. What you seem to be averaging is about 1 meg a second write and 2 megs a second read speed, so a 10 meg file would take 10 seconds to write and 5 seconds to read with the data that you used for testing. Hopefully that helps.

My son has the 64 GB and it worked perfectly. I am not sure about the 32 GB.

If I understood the description when I read about the comparison at the time I made my purchase, the Ultra disk downloads and records video faster than the 32gb. The Ultra is a class 10 which is a speed measurement and the regular 32gb is a class 4. How much difference is the actual speed I have no idea. This is the extent of my knowledge.

I wrote a non-techie review of my 64g and 128g. I compared writing 37.3 gig of data - the San Disk disk took 5:55 minutes for the 64g and 5:50 for the 128g. The other 2 (not cheapies) took between 25 and 36 minites. All were done with the same source data on the same computer using the same USB3 port. They were all USB 3 drives. Not sure what the specs are, SanDisk has them on their website, but I can tell you it is faster than any of the others out there except maybe the Lexar and the price on those is much higher.

Be careful, the advertisement is incorrect, the picture IS the part you're getting. Its 35 MB/s, NOT 90. And the write speed is about 2/3 of that (22-24 MB/s). I bought one and the company isn't particularly responsive to correcting the error in its advertising. I'm still working thru a case with Amazon as the part has since failed.

Yes it is in my case I currently have 4gb and find it fast enough for my needs but I will plan to upgrade in near future depending on my work

http://www.sandisk.com/products/memory-cards/sd/. Yes the read/write speed is 95 MB/s compared to 80/60.

I would imagine the 32 gig model is faster since it would have more flash chips on it. trust corsairs site over all other references which aren't highly trustworthy review sites.

Yes it is! I now have 8 of them! They are real fast write speed! Good card!

I just tried several shots with a 32 GB class 10 card and it seemed to clock in at about half the time you are experiencing at most.***Update*** I just purchased a SanDisk 64GB Extreme Pro class 10 and it says it is rated at 95 MB/s. The 32GB ws an Amazon Basics class 10 card. With the new card, there is no appreciable delay.I hope this helps.Don

Yes. I've got the same model; I upgraded from 2gb to 8gb, and it's working beautifully.

I tried to update from the company but it didn't work either. But it still running fine at the writing speed roughly 80-90Mb/s. But don't know for some reason sometimes fail to write

I am also wondering the same thing. But I don't think there should be any difference between the 8GB and 16GB models

rated speed for read/write. But Sandisk Class 4 tested among highest in lab tests.

No, this is just the speed that the interface can handle. In a perfect world, we would have 6Gb/s R/W speeds....

I have had no problems with this memory card, as far as download speeds. it has done its job very well, to determine that you also have to factor in network connection. The read speed is the up to 40.
