Samsung EVO Select 256GB microSDXC U3 Memory Card Review

Samsung EVO Select microSDXC 256GB Card

Introduction

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.

Performance

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.
