MicroSD cards solve the storage problem on phones, tablets, cameras and gaming devices but their tiny size makes them ridiculously easy to lose in couch cushions or washing machines. But the Samsung EVO Select 512GB somehow manages to pack half a terabyte of storage into something smaller than your thumbnail.
Amazon just dropped it to an all-time low of $32 for Black Friday, down from its usual $46 price tag. You get read speeds up to 160 MB/s, U3 and V30 ratings for 4K video recording, and an SD adapter that makes it work with virtually any device.
Keeps Up With Modern Files Size
The 512GB capacity holds about 100,000 photos, 80 hours of 4K video or 150 full console games, depending on file sizes. You can load your entire photo library onto it, download Netflix shows to watch on flights, and install dozens of Switch games without constantly juggling what stays and what goes. Considering modern smartphone cameras capture massive RAW files and 4K video that chew through storage in a blink, this much space is necessary rather than excessive.
Read speeds of up to 160 MB/s means that files actually transfer to your computer instead of taking hours. You can move an entire vacation’s worth of 4K footage in minutes rather than leaving your camera or phone plugged into your computer overnight. The write speeds support real-time 4K video recording at 60fps without dropping frames or stuttering.
The U3 speed class guarantees minimum write speeds of 30 MB/s which makes it suitable for burst photography and high-bitrate video. V30 video speed class certification ensures sustained performance during extended 4K recording sessions. A2 app performance class means you can install and run Android apps directly from the card with acceptable responsiveness.
UHS-I interface technology maximizes transfer speeds when combined with compatible card readers and devices. The interface supports bus speeds up to 104 MB/s, which the card utilizes to the fullest during file transfer operations. On the other side, older devices still operate using the standard SD interfaces, but at slower speeds. The included SD adapter transforms the microSD card into a full-sized SD card that fits cameras, laptops, and desktop card readers.
Water, extreme temperatures, X-rays, magnets, drops, and wear are all covered by six-proof protection. You can wash the card in your pocket or drop it in snow by accident without losing data. The durability goes beyond common consumer electronics, which makes these cards reliable for outdoor photography, action cameras, and rough handling. Samsung backs such durability with a 10-year limited warranty, well over what most competitors can offer, and indicative of confidence in long-term reliability.
The card will work perfectly with Nintendo Switch consoles for storing downloaded games and screenshots with no performance issues. You may finally create a digital library of your games without being forced to delete previously purchased titles just to make space for newer ones. Smartphones with microSD card slots receive huge boosts in storage for photos, videos, music, and apps. Android phones that have low internal storage benefit hugely from offloading media files onto the card. Action cameras, like GoPros and DJI drones, rely on fast and reliable cards to capture high-bitrate footage, and this Samsung card does so consistently.
For $32, this Samsung EVO microSD card offers flagship capacity and performance for less than what a good phone case usually costs.
