The Samsung EVO Select 256GB microSDXC card offers huge capacity and impressive speed. The new 256GB capacity card offers 95MB/s read and 90MB/s write speeds, well above the 80MB/s read and 20MB/s write speeds claimed for the lower capacity cards in the same series. The 256GB EVO Select card supports the high-speed UHS-I interface and is UHS Speed Class 3 (U3) rated to assure full HD and 4K video streams can be recorded without interruption. The U3 rating means the card can sustain at least 30MB/s write speed continuously. The lower capacity cards in the EVO Select series, 32, 64 and 128GB, are rated U1 (at least 10MB/s write speed). The 256GB microSDXC card (MB-ME256DA/AM) tested in this review was made in Korea. Samsung EVO Select memory cards are covered by a 10-year warranty.
Speed tests were run using USB 3.0 card readers. The highest sequential read speed benchmark reached 98.4 MB/s, well above Samsung's 95MB/s read claim. The sequential write benchmark measured 89.6 MB/s maximum, just reaching the 90MB/s write speed advertised by Samsung. These numbers are impressive for such a large capacity card and makes one wonder why Samsung put such a high performance card in the EVO Select line rather than the PRO Select.
