Samsung PRO Plus 64GB microSDXC Memory Card Review

Samsung PRO Plus 64GB microSDXC Card

Introduction

The Samsung PRO Plus microSD cards were introduced in mid-2015 and positioned just above the existing PRO series cards. Samsung claims PRO Plus series cards offer 95MB/s read and 90MB/s write speeds, compared with the 90MB/s read and 80MB/s write speeds of the PRO series. Samsung PRO Plus microSD cards are available in 32, 64 and 128 GB capacities. The 64GB microSDXC card (MB-MD64DA/AM) is tested in this review.

The 64GB PRO Plus microSD card is UHS-I compatible and rated UHS Speed Class 3 (U3). The U3 designation is used to identify cards that can sustain at least 30MB/s continuous write speed for HD, 4K and 3D video recording. Samsung PRO Plus memory cards are backed a 10-year limited warranty.

Performance

In performance benchmarks the 64GB Samsung PRO Plus microSD card reached up to 97.8MB/s sequential read speed. The highest speed was measured in the Lexar Professional Workflow SR2 UHS-II card reader. This is slightly above the 95MB/s speed advertised by Samsung. The highest write speed benchmark measured 88.2 MB/s, very close to the 90MB/s write speed claim.

It is interesting to compare the benchmark results of this 64GB PRO Plus microSDXC card with the 64GB Samsung PRO microSDXC card. The read speed benchmark results were nearly identical between the PRO and PRO Plus microSD cards, while the write speed of the PRO Plus was about 9MB/s faster on average.
