Is Lexar a good brand of micro SD?
Best microSD card for professional photographers It's impossible to cover storage media for cameras without including Lexar, as it's one of those brands that's been around since the dawn of storage. Great performance, excellent limited lifetime warranty, and another brand that's not let me down.
What does 633x mean on a SD card?
To help put it in more modern terms, a rating of 633x is equal to 95Mb/s read speed.
Which is better SanDisk or Lexar?
SanDisk is generally the most reliable brand. Actual failure rates are difficult to compare because reports aren't always centralized, but I did extensive online research looking for anecdotes about this, and most people reported that SanDisk cards were noticeably more reliable than Lexar and other brands.
How fast is a 633x SD card?
Lexar Professional 633x SDHC/SDXC UHS-I cards let you quickly capture and transfer high-quality photos and 1080p full-HD, 3D, and 4K video, with a read transfer speed up to 633x [95MB/s]. The cards leverage UHS-I technology [UHS Speed Class 3 [U3] for 32GB-256GB capacities] for high-speed, Class 10 performance.
