Navigating the various types and formats of Lexar memory cards can seem daunting at first, but understanding them is key to making an informed choice. Let’s break down the main categories you’ll encounter.

SD Cards (Secure Digital)

Standard SD cards are perhaps the most common format, widely used in DSLR and mirrorless cameras, camcorders, and some laptops. Within the SD family, Lexar offers several sub-types based on capacity:

• SD (Standard Capacity): These are the oldest, with capacities up to 2GB. While rare in new devices, some older cameras might still use them.
• SDHC (High Capacity): Ranging from 4GB to 32GB, SDHC cards use the FAT32 file system. They are a popular choice for many mid-range cameras.
• SDXC (Extended Capacity): Offering capacities from 64GB up to a massive 2TB, SDXC cards utilize the exFAT file system, making them ideal for handling larger files like high-resolution photos and 4K videos. Most modern cameras prefer SDXC cards for their ample storage.
• SDUC (Ultra Capacity): The newest kid on the block, SDUC cards shatter the 2TB limit, promising capacities up to an astonishing 128TB. While device compatibility is still catching up, Lexar is at the forefront of this emerging technology, paving the way for future ultra-high-capacity storage solutions.

When choosing a Lexar SD card, always check your device’s manual to ensure compatibility with the specific SD format. Using an SDXC card in a device that only supports SDHC might lead to compatibility issues.

microSD Cards

These tiny powerhouses are compact versions of SD cards, primarily found in smartphones, tablets, drones, action cameras, and portable gaming consoles like the Nintendo Switch. Like their larger counterparts, Lexar microSD cards come in HC and XC variants:

• microSDHC: From 4GB to 32GB.
• microSDXC: From 64GB up to 2TB.

Lexar also offers microSDUC cards for future high-capacity needs in portable devices. The diminutive size of microSD cards makes them incredibly versatile for devices where space is at a premium, without sacrificing performance or capacity.

CFexpress Cards (Professional Grade)

For the ultimate in speed and performance, particularly for cinema-grade video recording (like 8K RAW) and high-speed burst photography with advanced mirrorless cameras, Lexar offers CFexpress cards. These cards are significantly faster than even the highest-end SD cards, utilizing a different interface to deliver unparalleled data transfer rates. While they are a premium option, they are indispensable for professionals who demand the absolute best from their equipment. Lexar’s Professional GOLD CFexpress 4.0 Type B cards, for instance, are designed for such intensive workflows.

Understanding Lexar’s Speed Ratings: A Deep Dive

The front of a Lexar memory card is a treasure trove of information, packed with symbols and numbers that indicate its performance capabilities. Understanding these ratings is crucial for matching the card to your device and usage.

The “Numbers Game” on Your Card: Read vs. Write Speeds

You’ll often see two prominent numbers on Lexar cards: maximum read speed and maximum write speed, typically expressed in MB/s (megabytes per second).

• Read Speed: This indicates how quickly data can be transferred from the card, for example, when offloading photos and videos to your computer. Higher read speeds mean a faster workflow and less waiting.
• Write Speed: This is how fast data can be written to the card, which is critical for continuous shooting (burst mode photography) and video recording. For video, especially 4K and 8K, the sustained minimum write speed is far more important than the maximum peak write speed, as a consistent data flow prevents dropped frames and recording interruptions.

“According to our internal testing at Srkaj.com, while advertised peak speeds are impressive, real-world sustained write performance is the true measure for demanding applications like high-bitrate video recording,” notes Alex Chen, Srkaj.com’s Lead Memory Card Analyst.

Speed Classes (The “C” with a Number)

The oldest and simplest speed rating, indicated by a number inside a circle (e.g., C10), denotes the minimum sustained write speed.

• Class 2 (C2): 2 MB/s minimum write speed.
• Class 4 (C4): 4 MB/s minimum write speed.
• Class 6 (C6): 6 MB/s minimum write speed.
• Class 10 (C10): 10 MB/s minimum write speed. This is the baseline for Full HD (1080p) video recording and most modern digital cameras.

UHS Speed Classes (The “U” with a Number)

For higher performance, especially with SDHC and SDXC cards, the Ultra High Speed (UHS) class is more prevalent. These cards use a faster bus interface.

• UHS Speed Class 1 (U1): Guarantees a minimum write speed of 10 MB/s, equivalent to Class 10. Suitable for Full HD video.
• UHS Speed Class 3 (U3): Guarantees a minimum write speed of 30 MB/s. This is essential for smooth 4K video recording and high-speed burst photography.

UHS also defines the bus interface versions:

• UHS-I: Theoretical maximum transfer speed of 104 MB/s. Most common for U1 and U3 cards.
• UHS-II: Features an extra row of pins, allowing for simultaneous data transfer, resulting in theoretical maximum speeds of 312 MB/s. These are crucial for 4K and 8K video, and high-resolution RAW burst photography. A UHS-II Lexar card will often be significantly faster than a UHS-I card, but your device must support UHS-II to reap the benefits. If a UHS-II card is used in a UHS-I device, it will simply operate at UHS-I speeds.
• UHS-III: Theoretical maximum speeds of up to 624 MB/s, though products with this spec are not yet widely available.

Video Speed Classes (The “V” with a Number)

Specifically designed for video recording, these ratings are crucial for videographers. They indicate the minimum sustained write speed required for various video resolutions and frame rates.

• V6: 6 MB/s minimum write speed (suitable for HD video).
• V10: 10 MB/s minimum write speed (Full HD video).
• V30: 30 MB/s minimum write speed (4K video).
• V60: 60 MB/s minimum write speed (high-bitrate 4K and some 8K video).
• V90: 90 MB/s minimum write speed (high-frame-rate 8K video and professional cinema cameras).

Application Performance Classes (The “A” with a Number)

For microSD cards used in smartphones and tablets, Application Performance Class ratings (A1 or A2) indicate how well the card handles running apps and storing app data.

• A1: Good for running apps, offering a minimum random read IOPS of 1500 and random write IOPS of 500.
• A2: Even better for app performance, with higher minimum random read IOPS of 4000 and random write IOPS of 2000. This translates to faster app loading and smoother multitasking on your mobile device. Lexar PLAY microSDXC cards often feature these ratings, making them ideal for gaming.
