Lexar Professional 1066x microSDHC/microSDXC UHS-I Memory Card Review

Lexar Professional 1066x microSDHC/microSDXC UHS-I Performance Testing

Once opened and photographed, I hopped straight into testing. I slotted the microSD card directly into Lexar’s card reader and plugged it into my USB 3.1 motherboard port and fired up CrystalDiskMark to put the packaging claims to the test. I’m always nervous about “up to” claims, but as the image below shows, this card meets the mark.

Paired with a performant card reader and machine, we can see that the microSD card just about lives up to the claimed speeds on the packaging. With a read speed of 153MB/s and a write speed of just over 120MB/s, the performance is quite good. As the queue depth stacked up, of course, we can see both read and write performance drop off. Having fast performance like we see here is very important for a certain set of photographers and videographers. In my case, the 7D I shoot action with can take up to 10 full-size photos per second, generating 200-300MB/s of data. The faster the memory card, the longer it takes for the full speed cache to fill up on the camera and slow down the picture capture speed. When shooting action, you frequently need to take many pictures quickly to get the perfect shot.

I also tested copying over a batch of images in Windows Explorer. I moved 32 CR2 image files from my SSD to the microSD card. Windows reported a transfer speed of right about 100MB/s. Total data transferred was 717MB, and it took just 7.5 seconds.

 

Final Thoughts on the Lexar Professional 1066x microSDHC/microSDXC UHS-I Memory Card

There are some other nice touches that are worth mentioning. For instance, the card itself features no stickers, so there is no adhesive or paper to potentially jam up an expensive camera memory slot. The silver and black color scheme, while unlikely to be seen frequently, is appealing and sets it apart from other generic microSD cards that I have used in the past (and still occasionally use in Raspberry PIs).

With RAW photos weighing in at roughly 25MB a piece, a larger card is appreciated. It’s nice not worrying about running out of space when out on a shooting trip or at the critical moment during a wedding. The one major downside to relying on a larger card is if something fails, you lose that many more pictures. This is one reason I tend to stay with smaller cards. However, Lexar’s fantastic warranty lends trust that the card will remain functional for years, somewhat allaying the concern.

When it comes down to it, I can easily recommend this microSD card. It’s fast like it claims to be. But, it’s not too expensive either. At just $59.99 on Amazon (in the US), you’re getting performant storage and good capacity at a reasonable price. Whether you’re needing a new drone SD card or looking to expand your phone’s storage, look no further than Lexar’s 256GB microSD card.
