Transcend claims that both its 64GB and 128GB models have a maximum read speed of 95MB/s and maximum write speed of 60MB/s, and we found that our review card came pretty close. However, its write speeds proved inconsistent, fluctuating from a low of 20MB/s to a high of 55MB/s.
Read speeds were more consistent, frequently reaching between 70MB/s and 80MB/s, topping out at 87.1MB/s. While that's not going to match the speed of even the slowest modern SSDs, it's a decent speed for the kinds of tasks the card has been designed for, which is storing and viewing multimedia files such as videos, music and pictures.
