G.SKILL 64GB Secure Digital Extended Capacity (SDXC) Flash Card Model FF-SDXC64GN-U1

Pros: None

Cons: Bought this because of the name, size and the stated speeds.

Unfortunately read/write speeds were slow from the start, 10mb/s. But I just thought my USB card reader was being finiky with the new SDXC format.

Read speeds were then very slow in my Tegra 3 tablet for 6 months, CBR's took forever to load. But it still no errors or major problems, and mp3's ran fine.

Then 1 day the card was not visible, even after remounts and reboots. Attached the card to my USB reader and Windows instantly asked me to format, like the file system had disappeared, and all of the data with it. Luckily everything on it was just a copy from my main system.

Other Thoughts: Dealing with GSkill RMA support now. So far they've been nice and quick to respond. I'll see how the replacement goes.

Dear Customer

We are sorry to hear the product has been disappointing. It is strange the speeds were so low, they should be much higher than 10MB/s, depending on testing program used. Keep in mind that a recent high speed card reader is necessary for optimal performance; if not, speeds can be bottlenecked. Since you are having issues, please send it in for RMA exchange and a new one should work much better. All G.Skill flash cards are backed by a lifetime warranty. At any time it is defective or not working to specification, feel free to send it in for RMA exchange and a replacement should work much better. The G.Skill RMA process is quick and hassle free, so you can receive a new one shortly. For any further questions or concerns, please don't hesitate to contact us directly.

Thank you

Pros: Got this to have some extra storage on my Laptop because the SSD I had was only 80GB so it filled up fast. Used it to store documents, pictures, general files etc. It has held up quite well and transfers to and from run at decent speeds.

Cons: On occasion the card won't be recognized in the drive forcing me to take the card out and put it back in. Rarely happens and it's a minor pain.

Dear Customer

Thank you for your G.Skill purchase and review. Glad to hear the SDXC card is working well for you. This is definitely a great high capacity, high speed portable storage device. 64GB and it is only a fraction of the physical size of an SSD. It is a great extra storage device to store pictures, videos, documents, and so on. There is no better compact storage on the market today. For any further questions or concerns, please feel free to contact us directly.

Dear Customer

We sincerely apologize for the inconvenience. It is very strange the extreme capacity SD card failed abruptly. Please send it in for RMA exchange and a replacement should work flawlessly. This is a high speed, high capacity flash card so it should work very well with any device that can support 64GB. Write speed is the fastest on the market, so transferring large files such as HD videos or HD photos will be very smooth. Once you receive the new card, it should be much more reliable. Visit the Official G.Skill website for complete RMA procedure. The G.Skill RMA process is quick and hassle free, so you will receive a new one shortly. For any further questions or concerns, feel free to contact us directly.

G.Skill RMA procedure|

Pros: It's fast...it remembers stuff.

Cons: none

Other Thoughts: Bought this for my Nikon D5100, no problems here.

Pros: This UHS Class 1 card is very fast. The price was awesome at the time of purchase $45. I have had no problems with it across multiple platforms.

Cons: none so far.

Other Thoughts: Since I have only owned this product two weeks it is yet to be seen how reliable the card will be. Although G.Skill has an excellent warranty (lifetime).

Pros: good price if the camera would have recognized it

Cons: camera wouldn't recognize it. I am guessing this is a flash card problem and not a camera problem. camera had the latest firmware. the camera wouldn't even recognize the card to the point it would allow to format the card--so I couldn't even try that option.

Dear Customer

We are sorry to hear you are having issues. The flash card should be compatible with your Nikon D5100. If you continue to have issues, send the memory in for RMA and a new kit should work better. This is a high performance, high capacity microSD card that should work in most Nikon cameras. Should problem persist, we will contact Nikon to have this combination tested, and if necessary, a firmware upgrade to resolve the issue. For any further questions or concerns, please feel free to contact us directly.
