Capacity: 128GB Style: Memory Card Only
I’ve been using this SanDisk 128GB memory card for a while now, and I’m really impressed with its performance. As a part-time photographer, it’s been perfect for all my photo needs. It handles high-res images and large files without any issues, and I’ve had no problems with it during shoots. The card has been reliable and works seamlessly with my camera and laptop.

    • Reliable, Fast, and Worth Every Penny
Capacity: 1TB Style: Memory Card Only
I picked up the SanDisk 1TB Extreme PRO SDXC for my Maschine Plus, and I couldn’t be happier with the purchase. Right out of the box, it was ready to go—pre-formatted and up and running in seconds. No hassle, no setup stress—just plug and play. The speed is flawless, with no lag or stuttering, even under heavy workloads. I’ve experienced zero data loss, and the performance has been rock-solid no matter how much I throw at it. The 1TB capacity is more than enough for large sample libraries, beats, and projects, making it a game-changer for serious music production. When it comes to value, the price is absolutely justified—you’re paying for top-tier speed, reliability, and storage capacity. I’ve trusted SanDisk for years, and they’ve never let me down. Well, except for that one time I lost one—but that’s on me!

    • Reliable and Fast SD Card for Everyday Use
Capacity: 64GB Style: Memory Card Only
The SanDisk 64GB Extreme PRO SDXC UHS-I is a solid choice for users looking for dependable storage with fast read and write speeds. It offers read speeds up to 170MB/s and write speeds up to 90MB/s, which is more than sufficient for most photography and Full HD/4K video recording needs. The build quality feels sturdy, and the card is marketed as temperature-proof, waterproof, shockproof, and X-ray-proof — making it suitable for various shooting environments. Compatibility is broad, working seamlessly with DSLRs, mirrorless cameras, and even some video cameras. While it performs well in most scenarios, professional users working with high-bitrate 4K or RAW video might find UHS-II cards more suitable due to their higher sustained write speeds. However, for the price point and performance, this card offers excellent value. ... show more

Great memory card, as always. SanDisk has been a go to for many years. I use them with my 3D printer and they work well for that. Also use them in my camera and work well there too.
