Samsung EVO U1 SD Memory Card Review
The Samsung EVO card is one of Samsung’s slowest cards. It’s also a fairly old card as the new models of the EVO cards put out some decent performance. I…
Samsung Pro U1 SD Memory Card Review
The Samsung Pro U1 SD Memory card is a decent card from Samsung. It performs about the same as the Sandisk Extreme Plus except this card comes in a U1 variant, which could create problems for videographers. Samsung does have a U3 version of this card but it's much more difficult to find. It may have been discontinued.
Samsung memory cards also have some compatibility issues with 4k or XVAC S video in Sony cameras. And since this card isn't U3, it won't be compatible with Sony's advanced video codecs.
For casually shooting with any other brand like Fujifilm, Canon or Nikon, the Samsung Pro U1 card works great.
Sandisk Ultra SD Memory Card Review
The Sandisk Ultra is sort of Sandisk Junk card. They aren't yet available in the U3 or V30 speed class and their performance in general is very slow. But not all is bad with the Ultra cards. They do have some very impressive read speeds, but write speeds are usually on the bottom of the charts. This could still be a good memory card for videographers that are using cameras that don't record in a very high bitrate. For example the Micro-SD version of this card is a great sd card for the GoPro. This of course is not the micro version and I believe GoPro stopped using standard SD cards after the Hero3.
Sandisk Extreme SD Memory Card Review
The Sandisk Extreme cards sit further down the Sandisk family in terms of performance. Where the Sandisk Extreme Plus saw the same read speeds as the Pro and only slightly slower write speeds, the Extreme will have even slower write speeds and slightly slower read speeds.
This doesn't make Extreme a bad card, in fact the Sandisk Extreme cards are still great for many devices. A lot of entry-level cameras aren't capable of producing very fast write speeds, so this makes the Sandisk Extreme a great bang for the buck for those devices.
Sandisk Extreme Pro SD Memory Card Review
There is no question that Sandisk makes some of the best SD memory cards in the world, and the Sandisk Extreme Pro is their flag ship top performing UHS-I memory card. With in-camera performance and speed it almost always out performs all other brands, making the Sandisk Extreme Pro U3 memory card the best card you can buy for UHS-I devices.
Transcend U3 SD Memory Card Review
Transcend is one of the better memory card brands when it comes to performance. They're UHS-I cards aren't quite as fast as what you can get from Sandisk, Kingston and Delkin, but they are all around decent cards and Transcend is a very reliable brand that has been making memory cards for a very long time. They also have a wide range of cards that run at different speeds for different applications. I only use and test the fastest Transcend cards.
Lexar 600X SD Memory Card Review
The Lexar 600x has just about the same performance as the 633X but is a touch slower. The 600x is also only available in the U1 speed class where as the 633X can be found as both the U1 and U3 class.
In terms of performance and speed, the card is about average, it's not a very fast card but not slow either. The only reason you would be buying this card is if you wanted something inexpensive for a camera that didn't require high speed memory cards.
Delkin 633X SD Memory Card Review
The Delkin 633X U3 is an incredibly fast UHS-I SD memory card and gives even the top brands like Kingston and Sandisk a run for their money. The Delkin 633X is often in the top of the list with the in-camera memory card speed tests and Delkin is a very reliable and trusted brand. This makes the Delkin 633X a great buy for those looking for an alternative to the Sandisk Extreme Pro.
