Lexar Professional microSDHC 1000x and 1800x cards are the fastest of the land and they’re reliable

In the 4K video age, memory cards should be blazingly fast but even more so: dependable. Memory cards that break after five hours of use are a frustration at best and a catastrophe in many cases. The Lexar Professional microSDHC UHS-II 1000x and 1800x are both extremely fast and they won’t break that quickly.

After having shot a mix of 2.7K and 4K footage for a total of five hours over the course of 14 days, my A-brand MicroSD memory card suddenly gave up. The dreaded “SD Error” message appeared on the LCD screen of the camera. Whatever I did to bring this card back to life, it wouldn’t work. It was bye-bye to the footage that was on it. The card I used for that particular job was the brand most people will use when they’re not using Lexar. It wasn’t their first that died on me.

For some time now, I noticed that Lexar seems to be the manufacturer with a big range of the fastest memory cards available. That by itself was reason enough to review their two fastest microSDHC cards. After the experience with the broken card, I also decided to test the two cards for reliability. Previous Lexar cards have never failed on me, but I’ve also never shot in 4K before.

Consequently, I first ran a couple of speed tests and then used them for five hours on end each day for a period of four days. It’s not a scientific test, but it should at least give an idea of the Lexar Professional cards’ durability — especially in view of the heat that’s generated when shooting footage for five consecutive hours.

The performance tests were easy. The cards are claimed to have read speeds of 150MB/sec and 270MB/sec, and write speeds of 45MB/sec and 245MB/sec respectively. The claims for the Lexar 1000x were spot on. The higher rated 1800x was about 5% slower than claimed.

To see how reliable these cards are, I used them with a GoPro HERO4 set at 4K/30fps in its waterproof housing. From experience I know the GoPro gets really hot after half an hour or so. That should give me a good idea of how resilient the Lexar cards are with respect to a hostile environment. The competing card that I lost gave up after five hours of recording at a mixture of 2.7K/4K with the GoPro not even in its housing. The Lexar cards microSDHC hummed along fine after four days of recording. I have Lexar cards (that can’t sustain the speeds required for 4K) of five years old that I use all the time, and they’re still working without a glitch. I see no reason why the new cards would be any different.

The Lexar Professional 1000x microSD cards have completed the “Works with GoPro” verification process. The “Works with GoPro” program enables memory card manufacturers to ensure that their products achieve optimal performance and compatibility with GoPro products. Lexar microSD cards are specifically designed for high-speed capture of high-quality images and extended lengths of 1080p HD, 3D, and 4K video.


Lexar has been at the forefront of speed and efficiency for some time now. Their Workflow HR1/HR2 card reading stations boost productivity as you can offload multiple memory cards simultaneously. Lexar memory cards are faster than any other these days as well.

The Lexar microSDHC UHS-II 1000x and 1800x are no exception. For 4K recording, both cards will do. As these cards are not likely to break quickly and will therefore serve you for a long time, you can probably save money by buying a 1800x model because it’s fast enough to accommodate the higher transfer rates that will be needed in the future. It also fits the needs of RAW video recording and recording to high-bitrate codecs like ProRes.

The cards are reliable and that’s what you need when shooting video for a living. The 1000x is available in sizes from 32GB to 128GB and costs from around €48 to €140. The 1800x is available in the same sizes, but prices range from €89 to €300.
