Fast Write Speed In Canon 6D
This thing is a really nice upgrade so far. I usually take a few shoots to break in new cards so I went up to the mountains and did some bracketed panoramas and the card wrote really quickly and it was nice being able to see that histogram / image show up nearly instantly. I use a Canon 6D and tested it on RAW and all video settings and it recorded cleanly. I was using a Sandisk 32 gig 60/40 and those things are garbage now. I rarely shoot video so that was necessary but yeah the speed on this thing is worth it. I have only done one shoot with it so not too much experience with it but it looks and feels durable and it wrote quickly and uploaded quickly. Love it so far. Will update it if it dumps out on me.

5.0 out of 5 stars This Thing Is Blazing Fast -- Perfect for the GH4 4K Video
Reviewed in the United States on May 5, 2014
Capacity: 64 GBVerified Purchase
On my Apple computer using USB 3 this card averaged 60MB/s write and 80MB/s read speed. I compared this to my SanDisk 30MB/s card which I averaged 20MB/s write and 23MB/s read.

Before I got this card I was using the SanDisk card to record 100 mb/s video and it worked fine because you only need 12 MB/s to record that. If you want to recored the 200 mb/s you need 25MB/s.

None of that really matters because this card is crazy fast and very affordably priced.

For anyone not very familiar with how to treat these cards here is my recommended protocol.

1) When you put the card in your camera, format it in the camera. Never format it on your computer.
2) When you are finished with your shoot, take the card and copy your images to your computer. If your computer asks to delete the images on your card say no.
3) When you put the card back in your camera, format it.
4) Never, delete images in the camera. The only time you should delete images on your card is when you are reformatting it.
5) Don't use your camera card as a memory stick. Use a USB drive for that purpose.
6) Always, keep these protected in a case or your camera. Don't let them float around in your pocket with keys and loose change.

Following this protocol I have not had any issues with any card for at least 6 years.

5.0 out of 5 stars Excellent value; works perfectly in Panasonic LX100
Reviewed in the United States on July 29, 2015
Capacity: 64 GBVerified Purchase
The Transcend 64 GB High Speed 10 UHS-3 SDXC card is an excellent value. For the size and speed, it costs about half of what its competitors charge. I typically use Sandisk Extreme Pro cards, which have always performed well for me, but when I saw that this card was half as expensive with similar read/write speeds, I decided to give it a try. So far, it works superbly in my Panasonic LX100 for everything, including high speed burst shooting and 4K video.

If you're looking for a great value in an SDXC card, this is the card I recommend. If you have an LX100 camera, note that the manual only lists 48 and 64GB cards in its table of supported cards. I have heard reports that larger cards will also work, but I haven't felt a need for more space and I prefer to stick with what the owner manual specifies as a supported format/size. If that's what you're looking for, too, then this card should suit your needs perfectly.

Fantastic card! I almost puke in my mouth every time I go to a box store of some kind (Best Buy, Target, even Walmart) and see the prices they are charging people for flash memory that costs pennies on the dollar to manufacture! The amount of profit they make on these cards is absurd! I have ordered flash memory cards from Amazon for probably the last 5-6 years. This card in particular was a great deal and specifically was meant for my new Canon 80D for recording video and having a fast buffer speed. Every video I have created thus far has no zero issues with buffering video or pictures. I will be getting another 2 of these cards considering how great they have performed.

4.0 out of 5 stars Recovered From Error After First Use - Good Price
Reviewed in the United States on December 20, 2015
Capacity: 64 GBVerified Purchase
Used in a Nikon D750, there is no noticeable difference in speed compared to my usual card, the  SanDisk Extreme PRO SDSDXPA-064G-X46 SDXC Flash Memory Card with up to 95MB/s . I have NEVER had any issues with the SanDisk cards and practice terrible card hygiene: I save images for long periods of time, and use in multiple devices, and very rarely reformat (rather than reformatting in camera every time the card is inserted as the pros recommend).

However, this card produced and error making it unreadable in the camera after the first photo was taken. I was still able to read the card on my desktop, reformatted it (not "quick" reformat), and then the camera was able to read the card. No problems since and have shot a couple hundred photos. Maybe it was a fluke. If I have any other issues, I will probably stick with the  SanDisk Extreme PRO SDSDXPA-064G-X46 SDXC Flash Memory Card with up to 95MB/s  in the future.

5.0 out of 5 stars Great performer, especially for recent model DSLRs
Reviewed in the United States on April 30, 2015
Capacity: 64 GBVerified Purchase
Outstanding performance on a Canon 70D, compared to the Transcend 64GB High Speed 10 UHS Flash Memory Card TS64GSDU1E (up to 45 MB/s, 300x). The TS64GSDU1E is no slouch, but this is just obviously better listening to the two before one needs to measure with timers and so forth. The TS64GSDU1E allowed 16 continuous shots before slowing down, allowing a shot or two per second or so. This UHS-3 version allowed 21 continuous shots and the slow down was allowing a couple of shots per second or so. Both were tested after a in-camera format.
Might as well pony up the few extra dollars if you can afford it for the performance difference.
Note: If your device does not require high read AND write performance, consider the many highly regarded and reviewed class 10/UHS-1 cards for about $10-15 cheaper (look for specials) as of 4/2015. You only want to pay the extra money for card because of its high write speed. Yes, this card reads super fast but there are intermediate priced cards that read as fast but just do not write nearly as fast.
2nd note: We still regard the TS64GSDU1E as a very good card. But the ~10% price (4/2015 pricing) difference makes it hard to settle for the TS64GSDU1E.

Reviewed in the United States on February 15, 2015
Capacity: 128 GBVerified Purchase
I didn't realize the importance of UH-3 speed until I purchased this SDXC card. 4K UltraHD video requires a lot faster reads and writes to record reliably. Previously I was simply using a "class 10" rated card to record 4K and encountered intermittent failures to record. Since I purchase this class 10 UHS-3 card, I have encounter no more recording failures. The 128GB size is very nice for 4K video and I felt that the price was a bargain, given the performance of this card. Sure, 4K video *MAY* record with slower SDXC cards but if reliability is important to you when recording video, this UHS-3 card is a must. I have used this card in both Sony FDR-AX100 4K camcorder and Panasonic Lumix DMC-LX100 4K camera and it performed flawlessly with each!

These are great deals. I bought two. I'm going to buy more. There is free recovery software included so the price is unbeatable. I used them for three weeks out of the box, there were no problems. For 4K video these are very good. Put one in an HD camera and your good for 1/2 day. I have worked with wedding shooters who deal in large volumes of footage. The cards are mostly Transcend: No problems.

Je m'en sers pour synchroniser mes données avec historisation de toutes les versions des fichiers remplacés au cours de la synchronisation. Ce lecteur synchronisé mais sert de sauvegarde ponctuelle pour restaurer un fichier corrompu ou modifié par erreur. Il me sert aussi de déploiement de toutes mes données (environ 40 Go, photos comprises) sur un nouveau PC le cas échéant.

Très nombreuses écritures : très bonne endurance (deux ans d'usage sans aucun souci) de la mémoire et très rapide. C'est plutôt le lecteur de cartes intégré qui est le goulot d'étranglement avec un débit d'environ 35 Mo / secondes en régime continu.

Très bon produit, je le recommande !
