Review on 📷 SanDisk Extreme 256GB SDXC UHS-I Card (SDSDXNF-256G-GNCIN) [Updated Version] by Derek Evans

SanDisk has several cards called Extreme. The Extreme 90MB/s series replaces both the Extreme 60MB/s (16,32,64GB) and the Extreme 80MB/s (128GB, 256GB). This test compares the 32GB Extreme 60MB/s, 128GB Extreme 80MB/s cards and the new 32GB and 128GB Extreme 90MB/s Cards. The 32GB Extreme 90MB/s cards are an upgrade over the 60MB/s Extreme cards only in terms of read speeds. The card showed read speeds of up to 99,552 MB/s (Lexar SR2 reader). The write speed on the new card was slightly slower. That's still faster than SanDisk's advertised write speed of 40MB/s. 32GB Extreme 90MB/s = 95-99MB/s Read. 49MB/s writing. 32GB Extreme 60MB/s 75MB/s read. Write 55MB/s. Tests of 128GB Extreme 90MB/s and Extreme 80MB/s are almost identical. Read speeds weren't exactly the advertised read speed of 90MB/s, but both were faster than the advertised write speed of 60MB/s. Since Extreme 80MB/s cards have been around for a while, I believe SanDisk just changed the label to bundle them into the new Extreme 90MB/s series. 128GB Extreme 90MB/s = 85MB/s read. 78MB/s writing. 128GB Extreme 80MB/s = 85MB/s Read. Write at 80MB/s. Testing was performed using CrystalDiskMark 3.0.3 and tested on a dozen different USB 3.0 UHS-I and UHS-II SD card readers. For the price, the SanDisk Extreme 90MB/s is a great solution. The increased READ speed on a 32GB card is good when downloading images with a fast card reader. The 49MB/s write speed is pretty fast, but if you have a new UHS-I capable DSLR (SDR104 mode) you should probably consider 128GB or go for the Extreme Pro (90+ MB/s write speed). . . With). . Not all UHS-I cameras support DSR104 mode and can use the slower 50MB/s bus speed, making a slower write speed card suitable for many inexpensive or legacy DSLR, mirrorless, or compact cameras.
