What is the write speed of your SD card?

Don't know what you're using it for. I'm a broadcast professional and use these cards in my nikon to shoot video. If that is your purpose, you must use a Class 10. I just finished a documentary, and used 3 of these cards for the entire production. I couldn't have been happier, and the image was beautiful. Hope that helps.

I'm using: (2) 2x SanDisk Extreme 32 GB SDHC Class 10 UHS-1 Flash Memory Card 45MB/s

KE,I suspect you are confusing the 'Ultra II' with 'Class 2'. On each Sandisk Ultra II card it says '15MB/S'. So even if in real life you only get half of that speed, it is still much faster than class 2 (which means 2MB/S minimum).

I got the SAMSUNG MicroSDXC 64GB PRO Class 10 UHS-I Card for the fast read/write speed (70/20mbs). Search for best price!

this write speed is "normal" with all my sandisk ultra cards with all usb 2.0 devices. Tested in pc (h2testw) i can never get even close to class 10 write speed. Don't know what high end slr cameras or tablets are compatible with "Ultra" speed and don't care. Save your money and get a regular c10 card.

The speed of read/write are great but I am not certain if your camera has any restrictions for the capacity of the card.

Interesting. I never even knew that standard SD (not SDHC) were available up to 8 gig. I thought that they maxed out at 2 gigs. good to know. Wish the thing DID read SDHC at the card slot. Still, it's a pretty nice device.

It means the fastest class- however, it says that it has a 20mb/s write speed in DSLRs and 60mb/s transfer speed in computers The average small SD card that comes in a camera bundle usually does at least 30mb/s, but thats irrelevant if you shoot portraits or other non rapid fire photos

To each his own. May I ask why? What are you doing with your phone that you would want a faster write speed?

Yes--mine has one that was just kicking around the house. The higher "class" micro sd cards do write/read quicker, I think, so if you're buying one, that's worth considering.

As a class 10 device it's required to have a minimum of 10MB/s ... in standardized tests. (Meaning real-world could find it slower in certain cases.) No other speed is listed for it, so I'd have to assume that's it's speed. Especially as it was one of the early class 10 devices. So 40MB/s is highly unlikely. Besides, your camera gives you a list of recommended cards (of which this card isn't in the list) which would probably be the best place to look: SanDisk Extreme 32GB microSDHC (SDSDQXL-032G) SanDisk Extreme 64GB microSDXC (SDSDQXL-064G) Lexar 32GB SDHC 600x (LSDMI32GBSBNA600R) Lexar 64GB SDXC 600x (LSDMI64GBBNL300R) Delkin 32GB SDHC (DDMICROSDPRO2-32GB) Delkin 64GB SDXC (DDMICROSDPRO264GB) Samsung 64GB SDXC (MB-MGCGB/AM)

Speed doesn't matter for MP3 files, they are very low bandwidth. Think about it - memory cards are measured in Megabytes per second, MP3 files are measured in Kilobytes per second. So even a slow 1MB card is more than 3x fast enough for a very high quality 320Kbps MP3 file. That said, I only use the biggest available, which is 64GB - the only card I use is the "SanDisk SDSDQUA-064G-U46A Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s with Adapter" - conveniently made by the same company that makes the player. I don't care about the other features, but I do care about the 64GB size. Speed doesn't matter for MP3 files, they are very low bandwidth.

The card readers are all USB 2.0. Running a benchmark on a Class 10 SD yielded typical transfer rates of 30-35 MB/s.

Good question, and one that I posed to Eye-Fi. On 11/2/07 they replied as follows: ---------------- "Thank you for your interest in the Eye-Fi Wireless SD Card. "Eye-Fi does not share the information about the cards specific read/write speeds. I can tell you however, that the card is on par with the speed of basic consumer SD cards on the market. "I hope this information helps." ----------------------------- Draw your own conclusion from that response.

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

This thing is very fast never had a read issue. I think it would be more dependent on the speed class of the SD card. The USB speed on this thing blows my mind!
