The Nikon Z6 II is a versatile powerhouse, but its dual-slot configuration\u2014one CFexpress Type B\/XQD and one UHS-II SD\u2014often leaves photographers scratching their heads. To truly unlock that 14fps burst rate and high-bitrate 4K video, you can’t just grab any bargain-bin plastic. I\u2019ve spent years testing these cards in the field, and I\u2019ve found that while the Delkin Devices BLACK remains the gold standard for professionals, there are several fantastic alternatives that won’t break your gear budget.<\/p>\n<\/div>\n\n

Delkin Devices BLACK CFexpress Type B View on Amazon<\/a> View on B&H<\/a><\/h3>\n

When I\u2019m shooting fast-moving subjects, the last thing I want to see is the “Busy” light on my Z6 II. The Delkin BLACK is the most reliable CFexpress Type B card I\u2019ve ever used. While many cards boast high “peak” speeds, the Delkin BLACK focuses on sustained write performance, ensuring the buffer clears almost instantly even during 14fps RAW bursts. It\u2019s also built like a tank\u2014serialized and rigorously tested for extreme environments. In my experience, it handles the heat generated during 4K\/60p recording better than almost any other card on the market. The only real downside is the premium price and limited availability at some retailers, but for peace of mind during a once-in-a-lifetime shoot, it is worth every penny. If you are a professional who cannot afford a single dropped frame or a corrupted file, this is your card.<\/p>\n

ProGrade Digital CFexpress Gold View on Amazon<\/a> View on B&H<\/a><\/h3>\n
\n
Best For:<\/span> Enthusiast photographers and hybrid shooters<\/div>\n
Key Feature:<\/span> NVMe PCIe 3.0 x4 architecture<\/div>\n
Rating:<\/span> \u2605\u2605\u2605\u2605\u2606<\/span><\/div>\n <\/div>\n

The ProGrade Digital CFexpress Gold card is the “sweet spot” for most Nikon Z6 II owners. It offers a massive leap in performance over the older XQD format without the astronomical price tag of the “Cobalt” or “BLACK” series cards. I\u2019ve used the 128GB and 256GB versions extensively for portrait sessions and travel photography, and they\u2019ve never skipped a beat. You get read speeds up to 1700 MB\/s, which makes offloading your day’s work to a computer incredibly fast. While it doesn’t quite match the sustained write speeds of the Delkin BLACK for long-form 4K video, it is more than capable for the Z6 II\u2019s internal recording modes. It\u2019s a reliable, high-performance card that feels like a logical pairing for a mid-range full-frame mirrorless camera. For those moving up from SD cards, the speed difference during playback and file transfer will be immediately noticeable.<\/p>\n

\ud83d\udcb0 Budget Pick<\/div>\n

SanDisk Extreme Pro UHS-II SD View on Amazon<\/a> View on B&H<\/a><\/h3>\n
\n
Best For:<\/span> Backup slot or casual photography<\/div>\n
Key Feature:<\/span> V90 Video Speed Class rating<\/div>\n
Rating:<\/span> \u2605\u2605\u2605\u2605\u2606<\/span><\/div>\n <\/div>\n

If you’re looking to fill that second slot on your Z6 II without spending a fortune, the SanDisk Extreme Pro UHS-II is the industry standard for a reason. While Slot 2 is technically slower than Slot 1, using a high-quality UHS-II card ensures that the camera doesn’t slow down when writing to both cards simultaneously (Overflow or Backup mode). I often use this card for JPEG backups while my RAW files go to the CFexpress slot. It\u2019s rated V90, meaning it can handle almost any video mode the Z6 II throws at it if you choose to record to SD. The build quality is decent, though obviously not as robust as the metal-cased CFexpress cards. Just be aware that if you use an older UHS-I card in this slot, it will bottleneck your camera’s performance. Stick with this UHS-II version for the best experience.<\/p>\n

Sony TOUGH CFexpress Type B View on Amazon<\/a> View on B&H<\/a><\/h3>\n
\n
Best For:<\/span> Extreme environments and professional use<\/div>\n
Key Feature:<\/span> 5x more drop resistant than standard cards<\/div>\n
Rating:<\/span> \u2605\u2605\u2605\u2605\u2605<\/span><\/div>\n <\/div>\n

Sony\u2019s TOUGH series is legendary among photographers who work in the mud, snow, or rain. This CFexpress Type B card is practically indestructible, designed to withstand significant pressure and drops. Beyond the physical protection, the performance is blistering, with write speeds reaching 1480 MB\/s. When I\u2019m on a remote shoot where I can\u2019t easily back up my files, I trust the Sony TOUGH because of its superior structural integrity. It lacks the fragile ribs and write-protect switches of standard cards, eliminating common points of mechanical failure. It is undeniably expensive, often costing 30-50% more than “standard” cards of the same capacity. However, if you\u2019ve ever had a card crack in your bag or fail during a shoot, you\u2019ll understand why people pay the premium. It\u2019s a “buy once, cry once” investment for your Nikon Z6 II.<\/p>\n

Lexar Professional 2000x SDHC\/SDXC UHS-II View on Amazon<\/a> View on B&H<\/a><\/h3>\n

Best For:<\/span> High-speed SD slot performance<\/div>\n
Key Feature:<\/span> 300 MB\/s read speeds<\/div>\n
Rating:<\/span> \u2605\u2605\u2605\u2605\u2606<\/span><\/div>\n <\/div>\n

The Lexar 2000x is one of the fastest SD cards available, making it a perfect partner for the Nikon Z6 II\u2019s secondary slot. If you prefer to use your SD card for more than just a slow backup\u2014say, you want to record video directly to it\u2014the 2000x provides the speed required for 4K capture without hesitation. I find these cards particularly useful for weddings where I need to offload JPEGs quickly to a laptop for a same-day slideshow. The high read speed makes a massive difference when you’re transferring 64GB or 128GB of data. While Lexar has had some reliability ups and downs in the past, the 2000x series has remained a staple in my kit for years. It even comes with a small UHS-II card reader in the box, which is a nice added value. If you want the absolute best performance from Slot 2, this is the card to get.<\/p>\n

Buying Guide: How to Choose the Best Memory Card for Nikon Z6 II<\/h2>\n
\n

Choosing a card for the Nikon Z6 II is unique because of its dual-slot architecture. You have a choice between CFexpress Type B (which also supports XQD) and SD UHS-II. To get the most out of your camera, I always recommend prioritizing the CFexpress slot for your primary shooting. These cards are significantly faster and more durable than SD cards. When looking at specs, don’t get distracted by “Maximum Read Speed”\u2014that only affects how fast files move to your computer. For actual shooting, “Sustained Write Speed” is what determines how long you can hold the shutter before the camera chokes. If you’re a video shooter, look for cards with a V60 or V90 rating for the SD slot, or “Video Performance Guarantee” (VPG) for CFexpress. Price-wise, expect to pay a premium for CFexpress, but remember that these cards are designed to last for many years of heavy professional use.<\/p>\n
